“Look, look! Come and see what is inside this flower!”  It’s a warm, late-spring day and our friends are scattered around the yard, discovering the new surprises that have popped up overnight. The flowers are finally showing their beautiful blooms!

“Is it a bumblebee?” I ask. They look at me—their eyes big with wonder. It’s been many months since we’ve had flowers, and their young brains may not have retained that bit of information. “Sometimes the bees go inside of the flowers to get nectar and pollen. Nectar is like a little energy drink for the bees.”

“Nooooo! It’s black!” says Jamison. His friends gather around to take a closer look at the flower. We have just formed our curriculum for the day—or at least for the moment. We have science as we explore and gain a better understanding of the world around us. We have math as we count and discuss attributes and take parts and join them into a whole. We have language as we learn new vocabulary words. We have art at our fingertips as we explore the beauty of this flower in all of its blossoming glory.

I tell the children that the black pieces are called anthers and the tall green piece at the center of the flower is the stigma. “This is where the pollen and nectar are kept,” I say, “and why the bees like to buzz around inside of our flowers.”

“Can we drink the energy juice?” asks Eve, much to the delight of her giggling friends. Eve smiles, but I know that her brain is really trying to work this out.

“I think we should leave it for the bees,” I suggest.

“The bees will make honey from the nectar,” four-year-old Noah explains. “We can eat the honey but we can’t eat the nectar!”

I see Noah’s friends nodding, as this makes complete sense to them.

“Let’s have honey with our snack this afternoon,” I suggest to the delight of our class.

“This flower has five petals!” I turn around to see our subitizing queen, Annika, at it again. Subitizing is the ability to “see” a small number of objects and know how many are there without counting. When we roll dice, we don’t need to count the pips, we know the number when we see it. Some children grasp this concept easily, while others need to work with it a bit more.

We continue to count the petals, find the stem and leaves and find the anthers again. Individual flower parts are not exciting on their own but, when these pieces are put together, they make something more complex and more beautiful. The learning flows from the lips of the young friends as they share insights and ideas and think out loud as they process all that they are absorbing.

We find the dandelions on the hill and we are again measuring, building our vocabularies and investigating with the field of gold. “Look at how long THIS stem is!” shouts Violet.

I look over to see Claire in a world of her own. Quietly splitting the stem into pieces. Ah, decomposing. Math. Deep exploration to develop an understanding that will make sense in a classroom years down the road.

This is the learning that makes me smile. This is what learning can look like if we give children time to explore and move and play and figure it out in nature. This is the good stuff that sticks in the brain, like nectar to a flower. The foundations of math, science, exploration and investigation. Give your children the gift of nature and let the learning flow on their terms. The math and science and language are all just outside of your door. Enjoy!

If you’ve been fortunate enough to visit The Morton Arboretum in Lisle, Illinois, or driven by the Arboretum on Interstate 88, you may have spotted Joe the Guardian, a 20-foot-tall, spear-wielding troll peering down at the passing cars from atop his grassy berm. Joe is just one of six towering troll statues created by Danish artist Thomas Dambo. Fashioned from repurposed wood and other natural materials foraged from the Arboretum’s vast acreage, these incredibly detailed trolls have been delighting and inspiring visitors of all ages since they were installed as a temporary exhibition in Spring 2018. 

I like to say that Dambo never lost his childhood love of playing with loose parts. If you’ve followed my blog, you know about my own passion for using loose parts in early childhood classrooms! Some of our students have been fortunate enough to visit the trolls on weekends—and they are always eager to share their tall troll tales with their friends on Monday mornings.

Here’s some rare good news in a year that has had more than its share of bad news: The pandemic that has interrupted life as we know it has also put a pause on the trolls moving on!  If you have a chance to visit the Morton Arboretum before the end of the year, it’s worth a trip. Turn off those screens, get out of the house and breathe in some fresh air. This is STEAM learning in action that will inspire your own loose-parts play!

The Troll Hunt features a collection of trolls constructed from reclaimed wood. But these woody behemoths are 15 to 30 feet tall—a bit more than our gang is capable of constructing. Creating more diminutive trolls is definitely more our speed.

After several weeks of Monday-morning reports of troll sightings at the Arboretum, I took advantage of the trend. First, I printed out photos of the trolls to inspire our early learners to create their own versions of these mythical woodland creatures. Next, we sorted all of our loose parts into baskets and small bowls. Then we created trolls of various shapes and sizes out of small sticks, tree cookies, leaves, buckeyes, corks, shells and fabric—using bits of clay to connect the loose parts.

Architect Simon Nicholson first introduced the concept of loose parts back in the 1970s. Nicholson believed that we are all creative and that loose parts inspire children to engage in experimental, creative play, which is beneficial for child development.

What exactly are loose parts? They are materials that can be moved, carried, combined, redesigned, lined up and taken apart and put back together in multiple ways. They are materials with no specific set of directions that can be used alone or combined with other materials. (Kabel, 2010)

We like to think of loose parts as shells, rocks, sticks, acorns, feathers, pinecones, flowers, flower petals, fabric, water, sand, dirt, moss, leaves, bark, rocks, pebbles, pine needles, seeds and whatever else is native to your region. But we can also use blocks, people, animals and other manipulatives. Loose parts can range from dramatic play props to toy cars, pots, pans or pouring devices.

After studying the photos to determine the materials that were used to create the trolls at the Arboretum, the children noted that the hair on Dambo’s trolls was made from branches and observed the intricate detail on the troll faces and toenails.

Then they began to build their own trolls. At first, the children created two-dimensional trolls. But, as the troll workshop continued and they became more confident and creative in their use of loose parts, they began building in three dimensions.

“I need a leg that is the same size as his arms! See? These legs are too little!”

Jamie was not happy with his troll’s appearance. Digging through the bowl of small twigs, he discovered a longer “leg” and kept digging until he found another that satisfied him. Jamie was busy measuring, sorting and comparing his loose parts, employing nonstandard units of measurement. Sure enough, he was knocking out those early learning standards through play once more! This was a morning spent exploring concepts such as symmetry, geometric shapes and spatial awareness (how things fit in front, behind, next to or underneath something). Recognizing, predicting and building patterns are all important early math and science skills that lay the foundation for later STEM and STEAM learning.

As they engaged in these simple experiences, the children were becoming more proficient at problem-solving, reasoning, predicting and making connections in the world around them. By creating these opportunities for children to see the world through a different lens as they play with loose parts, we open up new avenues of exploration and discovery.

“Sally, you are using shells for your troll’s eyes,” Noa pointed out to her friend. “I used pine cones!”

By observing, asking questions and drawing conclusions, children develop scientific skills. Comparing and describing physical properties while creating their trolls allowed our young learners to think out loud and try out new ideas. When the children weren’t satisfied with how something looked, they would often rearrange the loose parts or start all over again. There was no anger or frustration—just calm exploration.

“Where did you find that grassy stuff for your hair?” Noa asked Sally. But Sally was deep in a state of creative flow. Sally often incorporates fabric into her creations and proceeds more slowly than her peers. But she is very deliberate about her choices. All of this takes time. We don’t need to look at the clock and decide when this activity should end. We can let the children decide. On this fall morning, the troll table sparked a play buzz that lasted for more than two hours as our troll makers followed their curiosity, becoming more confident as they took advantage of new opportunities to engage in art, math and science.

We rarely take walks without bringing home all kinds of loose parts—what the children refer to as “treasures.” If your child keeps small items in containers to create “things” with, your child is playing with loose parts! Take advantage of what you have around you. Those are your tools for setting up a math- and science-rich environment.

If you haven’t experienced the Troll Hunt at the Morton Arboretum, autumn is a great time to visit the Arboretum’s beautiful grounds and maybe find some loose parts along the way. Just be sure to call first to make an appointment, as the Arboretum is enforcing social-distancing measures to ensure visitors’ safety. Don’t forget to check into a membership when you pay for admission. That membership is your ticket to a full year of adventures at more than 300 gardens around the United States. It is a great investment or gift idea. Consider it a year of math and science curriculum as we hit the pause button on life to collect loose parts and scout out those magical, mythical trolls. Happy hunting!

“LOOK!” screams a four-year-old with such joy that we know this isn’t a garden-variety “I want to share something with you” moment.

As the gang rushes to her side, they come to a complete standstill, frozen in awe.

Oh happy day! Some kind souls have shared a fort with the community! There before us stands the most wonderful teepee-shaped fort that we have ever seen. Forts have been popping up all over town this year—and I couldn’t be happier about this trend.

This 14-foot high monument has sparked wonder and curiosity in all of us. We have stumbled upon a STEM adventure! This is math, science and engineering play that allows the learning to come naturally and at each child’s developmental level. This is also sharing. It teaches children that our community creates beautiful spaces to be enjoyed by all.

“Who lives here?” asks Liam as he bravely ventures closer.

“Can we go in?” questions three-year-old Madison, not sure that she really wants to.

We do go in, and the investigation into fort building sets us in motion for the day. Do you remember building forts when you were a kid? Did the memory of that fort just resurface? If it did, you retained that memory and are likely able to build another.

These are the moments that we like to create for our early learners. Hands-on learning enables children to take their understanding to a deeper level so that they can analyze the information that they have collected and then apply this knowledge when they create their own forts.

After giving everyone a turn to observe and discuss the masterpiece in front of us, we take a good hard look at the fort and investigate how it was constructed so that we can build a fort of our own.

We discovered this fort (above) while hiking in our neighborhood.

“I think this fort was started from that fallen branch!” Harper hypothesizes.

This leads to closer observation as we determine that this fort has sides that were built with sticks ranging in size from large to small. By leaning them against the main branch, the architects made the fort longer and wider. We begin to get a better sense of measurement as we visually estimate the length and width of the fort.

We always add a few sticks or branches to any fort that we discover, and today is no different. The older children quickly begin to add branches—an activity that reinforces our perception of the fort as a communal structure. When our younger learners hesitate, we reassure them that they really can’t go wrong by adding a stick or two.

“It looks like a triangle!” shouts Elizabeth. This declaration leads to an animated discussion about shapes and ways to incorporate doors, windows and other shapes into our fort.

We have a geometry class happening before our very eyes! We are looking at two- and three-dimensional shapes and using visualization, spatial reasoning and geometric modeling to solve problems.

These are opportunities that are rich in learning, creativity and team building. We share theories and develop hypotheses about the number of people it might have taken to build the fort, how they got the biggest branches up so high and how they created a base to stabilize the entire structure. We also examine the bottoms of the branches and hypothesize that they were probably broken off during a storm, rather than cut cleanly with a saw.

We know that our forts won’t look like the ones that we’ve encountered. We’ll have to use whatever materials we can find in our own play spaces. But our observations give us a better understanding of the fundamentals of fort and teepee construction. These found structures are the spark of inspiration that we need to design a fort of our own!

It’s time to bring out the assessment chart because this gang is on fire! This playful experience in engineering involves concepts such as angles, inclines, balance and elevation. When we let children learn through play, movement and trial and error, we lay the groundwork for the kind of deep learning that builds new neural connections.

Once the seeds are planted, the children often continue to develop their fort-building skills in our program or in their own backyards.

When the Midwest experienced a rare derecho in August 2020—and every house in our area suddenly had a backyard full of branches—our students immediately began collecting the fallen branches to build forts in their neighborhoods.

They had joined the community-wide fort-building movement!

Notice the similarities? By giving our children long periods of uninterrupted time to play and investigate, we empower them to build their own forts and develop new STEM skills and insights that they will be able to transfer to worksheets when the time is right.

When our students returned to our program this fall, we began napping outdoors on a daily basis. Not surprisingly, when a parent suggested a weekend nap to their child, the child insisted on napping outdoors—in her fort. When children build structures, the joy comes not only from the building but from returning to this place that they have created by themselves, for themselves.

These are the moments when I thank our anonymous community of fort builders for “planting the seeds” of fort building with our young learners. These industrious fort architects may be 12 years old or 90 years old. They may be building these impromptu structures to offer protection from the weather, bring joy to others or simply provide a peaceful place for fellow community members to commune with the natural world.

These lovely forts are gifts of time, hard work and beautiful design that bring science, math and engineering into the lives of our youngest citizens.

Thank you for making so many moments of STEM learning possible through play with the children of our community! You inspire all of us! Thank you! You are truly changing our world!

“I found an empty nest! Can we keep it?” Owen’s joyful discovery captures everyone’s attention.

Three-year-old Avery comes running. “Are there eggs?” she asks her older and wiser five-year-old friend. “Can I see?” she begs. “Please let me see?”

“There are no eggs, just an old nest. Can we please keep it?” pleads Owen.

After a quick glance to confirm that the nest cradled in Owen’s hands is not harboring a feathered inhabitant, I grant my permission.

Owen handles the nest gingerly before realizing that it is sturdier than it looks. After a few tugs and a few moments of studying the nest, he very gently hands it over to the others.

We have a collection of nests. We love to study the materials used to build each nest, as well as the nest construction methods used by different local bird species.

We also try to guess the type of bird that built each nest and how many eggs might have been laid in these cozy homes crafted from sticks, grass, leaves, string, mud and other found objects.

I watch Ave silently investigating and collecting data as she turns the nest in one direction and then another. You can almost see the wheels turning.

“I think the bird used some litter [drinking straws, food wrappers and other debris] to build this nest.” Ave giggles. “And there are like a million sticks in here!”

“A million?” I echo.

“Maybe more!” Ave theorizes.

This moment gives me a valuable insight into Ave’s nascent number sense. Connecting numbers to quantities is a skill that will continue to emerge and evolve with age and brain development.

“The bird added string—and look at this piece of wire she wove in!” shares Maya. “It’s lightweight but very strong. How long does it take her to make this nest? I think this nest is smaller than the others we have.”

This is how we set our curriculum for the day—by following the interests of the children. When we return to our indoor classroom, we will dig out our books to learn more about the various engineering practices that local birds use to build their homes and compare this newest nest to the others in our collection.

Living along the Mississippi River as we do, we are blessed with the return of our beloved bald eagles each winter and spring. From December to March, these magnificent birds migrate south from Canada and often make our area their winter home. Some even like it so much that they make it their permanent home.

In the fall and winter, the eagles rebuild their nests to prepare for the hatching of the eaglets. Eagles nesting in our area typically lay their eggs in mid-to-late February, and the eggs hatch by mid-to-late March.

Once the eggs have hatched, the female stays with the eaglets while the male leaves to find food for the female and her hatchlings.

The eaglets grow quickly and are ready to fly—or “fledge”—by late May or early June. A number of webcams have been set up by organizations in the area so that we can watch the life cycle of the eagles playing out before our eyes.

This is where I struggle. We are a screen-free environment. I know that we can link to so much learning with technology. I know that I need to stop being so stubborn. I am that old-school playground leader who hasn’t embraced the many educational benefits of 21st-century technologies.

We weren’t always screen-free—and I have fond memories of the year when we observed a wee bit of eagle life via webcam.

I hated the screen, but I loved learning about our local eagles. When an eagle brought a large fish to the nest, we were spellbound. But the fact that we’d been sucked into spending time staring at a screen contradicted everything that I believed in regarding early education—and I was overcome with guilt.

So when the first warm day of spring arrived, we created our own eagle’s nest in the center’s outdoor play area.

“Declan, how big is an eagle’s nest?” I asked, measuring tape in hand.

“Seven feet wide,” he responded. “What are you doing?”

I quickly measured out seven feet and put a heavy rock from the rain garden on the spot. The children began adding rocks until we had a circle that was seven feet in diameter.

For a few minutes, the children pretended to be eagles living in a happy little rock nest—until one perspicacious preschooler called me out.

“Wait! This isn’t a nest!” Asa declared. “We need to add sticks and leaves and yarn. We need more!”

“We do need branches and sticks!” agreed four-year-old Joshua.

“Over here!” directed two-year-old Gabe.

Game on! Now we were learning, creating and analyzing. We’d taken what we’d learned during our screen time and translated it into real-life, hands-on learning that met so many of the math and science standards that they would struggled to achieve on a worksheet!

This was when we grabbed our books and discovered that an eagle has a wingspan of 6-8 feet. We also learned that a mature eagle has 7,000 feathers, weighs 8-11 pounds and has vision so keen that it can see the print on a newspaper at a distance equal to the length of a football field. These are the details that young children are likely to absorb.

Because bald eagles are most active from sunrise to 11 a.m. as they feed along the open water of our locks and dams, this coincides quite well with our outdoor times. Lucky for us, they return to their roosting areas in the afternoon hours.

After lunch, some time spent browsing through eagle books and a nap, the boys made their way back out to their new eagle’s nest. If they build it, they will play in it. They had been playing there for a good long time when, sure enough, up in the sky, an eagle appeared!

Yes, a  real live eagle! Would she think this was HER nest? Could she see the boys in HER nest?

As the boys contemplated the possibility of the eagle swooping down and landing amongst them, they scrambled out of their nest in pure terror.

The eagle did not land in our nest. But, sadly, our frightened little learners never returned. I left the nest in place for over a week, and some of the younger children played in it, but the boys who built it kept their distance!

I often find that most of the fun is in the building phase of the project. The collaborating, creating, adding, subtracting, analyzing and evaluating with friends is actually the play for building kids. This is the good stuff that happens with play; enough time to engage in deep, investigative learning; and, sometimes, just the right amount of technology.

Take time to follow the lead of your students and see where their interests and curiosity take you. Then match their learning up with your early learning standards.

This link will take you to the Arconic Eagle Cam.

Full disclosure: The male eagle will bring food back to the nest. This could be a raccoon, a fish or a mouse. It is nature. It is graphic. It can be addicting or terribly uneventful at any given moment!

When we build nests of our own, we often use this Scientific American site as a reference. But if you’ve lingered too long on the Arconic Eagle Cam link provided above and feel guilty about overdoing the screen time, you can just WING it—pun intended!

Ha! Let’s get outside and play.

“It works! The water is coming out!” Rokia cannot contain her excitement as the discovery of a full rain barrel adds a new avenue of discovery and learning for our week.

“How did you do that? Can I have a turn? Get a bucket!” The excitement builds as so many little brains begin to figure out what is happening here. We have hypotheses, theories and observation humming away. There is nothing like water to bring a group of children together for a day of play and learning that can help you meet your curriculum goals.

As the United States begins to open up with precautions in place to prevent the spread of COVID-19, there are opportunities to literally change the landscape of early childhood education by spending more time in outdoor spaces.

The best place for our children as we navigate this “new normal” is in nature. Studies show that sunlight, higher temperatures and humidity are detrimental to the survival of the coronavirus.

We also know that exposure to dirt helps young children develop healthy microbiomes and strong immune systems. Outdoor activities make social distancing easier—and research suggests that outdoor learning can deliver many other benefits, from boosting mood and increasing concentration to reducing stress.

You can meet many important early learning standards easily with outdoor play. And once you take your curriculum outdoors, you may never want to head back inside!

It’s important for anyone working with young children to understand the enormous potential for learning and brain development that exists when children are connected to nature. As children actively use their senses to explore the natural world, they are forging new neural connections and strengthening neural pathways through sensory play.

In short, outdoors is where our children need to be—and setting up an outdoor classroom is easier than you think. You don’ t even need to have a natural setting.

Water is a great place to start because we want the children in our care to wash their hands A LOT during the pandemic—and we can set up water play just about anywhere.

Incorporating water into our daily play with a rain barrel was one of the smartest things I ever did. We love using rain barrels for scientific exploration and discovery, as well as teaching children how to be good stewards of the earth’s limited resources. Many cities give away rain barrels for free to promote water conservation. If your city doesn’t have a rain barrel program, you can purchase a rain barrel for $50-$150 or make your own from a plastic trash can with a lid.

The children love to use the spigot on our rain barrel to explore the concept of flowing water and control the water’s flow. Let me tell you, being in control of something so powerful is a pretty powerful experience in its own right!

The communication and social-emotional skills that develop during this outdoor activity are worth their weight in gold. If your building has a downspout or an outdoor water source, that may be where you place your rain barrel. During very hot, dry summers, we sometimes have to resort to filling the rain barrel with our garden hose. By taking the time to think about these issues, you will help ensure the success of your own rain-barrel adventures.

We are also big proponents of tubs for water play. We use everything from big plastic tubs to utility tubs from auto stores to bus pans from restaurant supply stores to commercial school-supply tubs. This summer, we are adding soap bubbles to the buckets to encourage play and kill germs in a calm, not-in-your-face-scary-virus way. Doing this in front of the students will be a whole science and math lab in itself as they discuss the addition of ingredients, the change in matter, the chemical reaction that takes place and the change in physical properties. So, yes, grab those standards! This is the hands-on learning that we love—all while keeping our children safe from germs!

We were fortunate to have a handyman in our lives with the vision and skill to create a working pump. We buried a short, wide rain barrel and connected it to the farmhand pump. If you’d like to give this a try, you can get the step-by-step directions here. This pump has added hours and hours to our investigations and play. We absolutely LOVE our pump, and it is one of the most popular additions to our outdoor classroom. Many an hour has been spent here learning about cause and effect as the children see “what happens if….” Trust me, they have investigated the craziest ideas that adults just wouldn’t conceive of!

“Eve, come see!  Look what’s crawling under the bridge!” Jamison has discovered a daddy longlegs out for a morning stroll in our rain garden. Many cities and towns across the U.S. are beginning to award grants for rain gardens. We took advantage of our local grant program and created a rain garden filled with native pollinating plants and a dry creek that gifts us with insects, an occasional toad or two, and plenty of opportunities for exploration, observation and investigation.

Last summer, we added a mister connected to a simple garden hose to our tree. With pools closed during the pandemic, this mister (which we ordered from Amazon) is a great alternative that you can take advantage of without great expense or worries about water safety. We supplement the mister with big tubs of water and plenty of buckets and spray bottles. Heavy buckets of water and spray bottles are great resources for building strong arms, wrists and fingers for future pencil gripping. Bring in measuring cups, measuring spoons, tall containers and short wide containers and you have set your students up for outdoor learning activities that will foster the development of predicting, data analysis, probability and geometry skills.

It won’t take the children long to figure out that the mister will afford them many opportunities for water collection. This, in turn, will encourage pouring and measuring and experimenting with volume. Nearby plants, flowers, rocks, shells and other loose parts will add to the value of the play. When children make dandelion soup or rock salad, they are combining, collaborating, creating and imagining. It’s all there for us to document. They don’t need worksheets, they need play!

As we navigate our way around the pandemic, maybe we need to return to the roots of early childhood education by taking a page from the playbook of the German educator and nature lover Friedrich Froebel, who founded the first kindergarten (which translates literally to “children’s garden”). Froebel’s original kindergarten model in 1837 emphasized time and opportunities for children to connect with natural materials in a garden for play. Maybe this is what kindergarten could and should emulate as we reimagine early childhood education this year.

All of the activities that you need to meet your math and science standards are awaiting you in the garden. Head outside and lay the foundation for math and science success with a developmentally appropriate day of nature play.

Let’s take back what early education could look like in America. Join me!

“AAAAUUUUGHHHHHHH! Worms! Look, look! They are everywhere!” Eleanor is jumping up and down hysterically. Nothing will bring our crew running faster than a good worm sighting!

Let the earthworm exploration begin. We love worms!

Last spring, we witnessed an unusual natural phenomenon as a mass of earthworms wiggled out of their subterranean homes in the soil and squirmed onto our sidewalk.

This weird worm event elicited great joy and excitement from our early learners as they raced over to investigate.

There are a number of names for a large group of earthworms, including a bed, a bunch, a clat or a clew. So if you casually refer to a squirming mass of earthworms as a bunch, you are technically correct!

Why are there so many?  Why are they tangled?  Will they bite me? Where is the worm’s mouth?

The curiosity is flowing faster than the answers. When you see excitement at this level, embrace the moment! Grab a camera and start documenting the Illinois Early Learning Standards that you’ll be meeting today!

Worms can be used to teach length—and we sometimes measure them with tape measures. But this is just one of the ways that worms spark investigation, inquiry and analysis in our outdoor curriculum.

Our love of worms has afforded us days and days of study. In the photo above, you can see collaboration, hypothesizing, theorizing and prediction in action.

This is a group of three-year-old scientific investigators—and their brains are on fire! This is STEM exploration at its most engaging as we measure, count, estimate and subtilize while learning about earth science and life science.

Our students are learning that living things grow and change. They are drawing conclusions from their investigations as they scrutinize the worms’ anatomy and behavior.

This fact-finding mission also fosters a respect for life in all its forms. We try really hard not to hurt our worms. When a two-year-old child engages in hands-on investigations with an earthworm, it doesn’t always end so well for the worm. To protect the worms from overzealous handling, we’ve taught the older children to monitor the well-being of the worms in the hands of their younger peers. This is hands-on learning, coupled with collaboration!

As your early learners explore the world of earthworms, encourage them to ask questions that will guide their investigations. By encouraging them to engage in deeper scientific inquiry, you’ll be setting them up for academic success in the years to come.

“Can I hold it? ” asks two-year-old Alex.

As an older friend passes a worm to Alex, she pulls her hand back a few times before she is ready to receive it.

We offer Alex a glove, but she wants to be like the “big kids” and go gloveless. After we reassure her that the worm has no teeth or pincers, she tries again. This is a good example of the importance of time and patience as we guide children through the investigative process.

People often ask how we “get” our kids to hold a worm. We read a lot of books about worms and I make sure that there are worm books on our shelves from March through October. We also observe worms for long periods of time. If our early learners have one brave friend who is willing to pick up a worm, that’s all it takes to persuade the others to persevere, despite their initial trepidation.

As the children engage in their hands-on worm investigations, we throw out facts, often in whispered voices: “Did you know that worms do not have teeth? Worms also do not have pincers or stingers. They have no eyes, legs or arms. They will never hurt us.”

These are the facts that I share with young learners who are anxious or experiencing worms for the first time. A child who investigated worms as a two-year-old last fall may not have retained that memory as a three-year-old—and we may need to reintroduce worms this spring.

Retention and problem-solving skills continue to evolve as students seek answers to their questions through active investigation. Last fall’s observer may be this spring’s hands-on investigator. Our students need long periods of time to observe and learn as this curriculum unfolds in front of their eyes.

By creating an environment that leads to discovery, you are setting your curriculum in motion. Add large rocks, tree cookies or even soil-filled planters that can serve as worm habitats. Some teachers add soil and worms to their sand and water tables to create worm farms in their classrooms. Our goal is to foster the development of inquisitive minds.

We extend our learning with songs and finger-play. We enjoy “Eat Like a Worm Day” as we snack on vegetables such as carrots, cucumbers, lettuce and apples. We make “worms” out of clay—some thick, some thin, some short and some very, very long.

Mr. Nicky (pictured above) has a wonderfully funny song titled “Earthworm,” that has taught our children so much about the vital role that worms play in keeping our soil healthy. There are many silly worm songs, but this has a great hook and gets our children moving as they learn new facts about worms while having fun. It’s one of our favorites.

We always try to return worms to their natural habitat when our observations are over. We thank the worms for doing their part to make our lawn healthy and beautiful as we release them back into the place where we found them. We send them home to their families, which resonates with our young learners.

We wish you many happy STEM adventures as you and your early learners study these champions of the soil.

Happy worm hunting!

“I see the daddy cardinal, do you know where the mama bird is?” Four-year-old Noah, binoculars in hand, is busy counting birds in our outdoor classroom.

Are you aware that the annual Great Backyard Bird Count is coming up later this week? This is a great opportunity to create a bird-watching station and knock out some STEM and early learning standards while encouraging family involvement.

Mark your calendars for Feb 12-15 and join us for this fun and educational week!

February and March are good months for bird watching and bird counting in our program. This is a great way to accelerate STEM learning on days when below-zero wind chills make outdoor play impossible.

We have bird feeders set up right outside of our windows so that we can set up indoor bird-watching stations to give the children close-up views of their feathered friends.

We provide clipboards, books, binoculars and our abacus to help with the bird count. We also use this opportunity to teach our students how to tally on a tally chart. We reference the eBird website, which shares local sightings of different bird species.

I take the top ten birds sighted in our area on the eBird website and add pictures of those birds to our abacus. To do the same thing, just add your location to the eBird website and you’ll see which birds are sighted most often in your area. It’s quite fabulous!

We also like The Cornell Lab and the Audubon Society. I have the Cornell Lab Merlin Bird ID app on my phone to help us identify birds by their songs.

Your local U.S. Fish and Wildlife Service may also be able to provide free materials for bird identification. There is a big difference between bird identification books for children and those that were written for mature bird watchers. I would check some out at your local library or bookstore before purchasing.

This is a great opportunity to practice not only counting, but grouping by attributes or close observation of the differences between a downy woodpecker and a red-bellied woodpecker.

We try to keep a ruler nearby for our older children to use to determine whether they have spotted a six-inch downy woodpecker or a nine-inch hairy woodpecker. This offers the children an opportunity to use estimation and practice using real tools for observation.

This is also a great time to introduce Venn diagrams for clarification and documentation.

By creating a comfortable and inviting place for the children to birdwatch—complete with pillows, chairs and tables with baskets of binoculars—you can encourage them to slow down and observe more often.

By planting native plants in your outdoor classroom, you will also attract more birds to your bird-watching stations.

We remind our kids that outdoor birds are hard to spot but easy to hear. We ask them to close their eyes and point to where the song is coming from. I like to teach common mnemonics like the American Robin’s cheery up, cheerio, which can be picked up on almost any bird walk in the United States. Learn some mnemonics for common birdsongs here.

We have tried the inexpensive plastic binoculars from school-supply stores and toy aisles. They really didn’t work well and broke the same day that we brought them out. Smaller, child-sized binoculars are much easier for little hands to manage. Children enjoy using “real” tools and will treat them with much more respect than a pair of cheap plastic ones. I often teach them how to focus the binoculars to get a clear image. I place these binoculars in a basket, along with the identification books. We also stock our bookshelves with a wonderful collection of books about birds, nests and hatchlings.

We talk so much about STEM these days. This is one of the easiest and most magical ways to create a learning hub that can inspire young learners to engage in STEM exploration and discovery.

By participating in these learning adventures, you can learn right along with the children as you observe, ask questions, draw conclusions and discuss your findings with your early learners.

When we observe birds from our indoor birdwatching stations and then take those same observational skills outdoors, we have a deeper understanding of the birds we see and the birdsong we hear.

By adding the technology from the websites mentioned above and building bird feeders from oranges or peanut butter and seeds, we can include engineering in our learning adventures. We can include math as we count the number of birds arriving at the feeder and then subtract the birds that fly away. By grouping, measuring and comparing the birds, we can meet our early learning standards and benchmarks.

I hope you will join us in our Great Backyard Bird Count this year. Birds of a feather flock together. Come join the fun!

“Evie, come look! I’m a superhero! I have superpowers!” calls Jamie from the foyer.

Curiosity piqued, Evie leaves her blocks behind to see what her best friend is up to now.

“Rainbows!!!” Evie shrieks as she spies the colorful light pattern on Jamie’s wrist.

Everyone within earshot dashes over to see the rainbows. And, just like that, our morning activities morph into a joyous exploration of light and color.

Squeals are the soundtrack for this sudden spasm of joy as the children dance around the room “catching” rainbows.

The rainbows that have inspired this impromptu STEM investigation are coming from the leaded-glass windows on our old schoolhouse.

During the winter and early spring, the sun hits these windows at just the right angle and we find these refracted-light rainbows on our walls, the floor—and even on the faces of napping children.

“I know the colors of the rainbow!” Noah sings. “R is for Red, O is for Orange, Y is for Yellow…” 

A chorus of little voices joins in, along with requests for our favorite “ROY G. BIV” song from the children’s CD, Here Comes Science (see image below).

The song is used as a mnemonic aid to help children remember the colors of the visible light spectrum in order of increasing frequency: Red, Orange, Yellow, Green, Blue, Indigo and Violet.

Color recognition marks an important developmental milestone.

Color identification helps children strengthen the cognitive link between visual clues and words.

Noah is singing the ROY G. BIV song while pointing to each color. As I watch, I make a mental note to check off color recognition, vocabulary and sequential ordering on Noah’s upcoming learning assessment.

I attempt to explain that the rainbows in our classroom are created when the sunlight gets “split up” as it passes through a cut-glass window that bends the light.

“Red tends to bend the least, so it appears on the top of the rainbow, while violet bends the most and ends up on the bottom,” I state.

My jabbering is met with silence. The children are deep into their own investigations.

“The librarian told us that rainbows are actually circles, but they look like arches when we look at them from the ground,” says Owen.

Heads pop up. Owen’s comment is met with quizzical expressions as the children try to process this information.

“If we dig down into the ground would we see the rest of the rainbow?” Roberto asks. 

“I don’t know,” shrugs Owen, glancing around at the rainbows in the room.

“What’s an arch?” asks Thali.

“You know, that part of the circle that looks like this,” says Jamie as he creates a half-circle with his hands. “It’s like you cut a circle in half!”

Thali nods and the focus of the group returns to the rainbows in the room.

This interaction prompts us to bring out our prisms and inject a bit of STEM into our hands-on play. Throughout the day, we experiment with other materials and sources of light.

First, we add Magnatiles to the windows in our block area (above).

Then we grab our liquid tiles (below) and place them in the window frame. We love these tiles and play with them often, but this is the first time we’ve tried to place them in the window. The colorful liquid in the tile is reacting to the pressure of Sally’s fingers, stimulating her sensory, perceptual and spatial pathways.

I offer a large liquid floor tile to our younger learners. Some of the older children immediately join in the exploration, adding enough weight and pressure to move the liquid and stimulate the senses of our younger friends.

If you don’t have cut-glass windows, a simple window film can bring about the same results. We added this film to the window below, and we are greeted with rainbows whenever the sun shines!

When these spontaneous moments of learning land in our classroom, my goal is not for the children to completely comprehend or master a topic.

My goal is to learn with them, to pique their curiosity with investigative opportunities and to allow them to engage in scientific inquiry while playing with light.

The act of playing with light, reflection and color invariably evokes a sense of wonder.

So seize the moment for some impromptu STEM play when a rainbow spontaneously appears—and expand the options for color and light exploration with a few new prisms and props!

“Hey everybody! Look at all of the tomatoes that are ripe today!” shouts Jacob to the gang.

“Can we eat them for lunch? Can we?” asks Lucus.

“Can we eat them now?” pleads Elizabeth.

It’s early September and preschoolers around the country are learning about apples, but we have tomatoes at our fingertips. The same tomatoes that we planted in the spring, watered, watched and then forgot about and ignored. But today these plants are full of red, ripe, juicy tomatoes. For the foreseeable future, our curriculum will revolve around tomatoes!

There’s been a lot of talk recently about curriculum themes and how they fit into early childhood education. So much of the learning that takes place in early childhood settings is spontaneous, rather than intentional. This doesn’t mean that early childhood educators shouldn’t be intentional about their curriculum development. They should. But great teachers are always willing to set their planned activities aside to seize a great learning opportunity when it arises.

I call these unplanned learning opportunities “teachable moments.” In so many ways, the child is the curriculum. By observing our early learners closely to see what ignites their curiosity, we can identify and build on the teachable moments that we encounter throughout the day.

Once we’ve identified a teachable moment, we can make the most of these spontaneous early learning adventures (and meet our early learning standards) by sharing our insights and asking questions that encourage children to dig deeper and make more connections as they engage in rich, authentic, hands-on learning that only looks like play.

After we engage in these impromptu investigations with our early learners, we can share the fruits of their learning adventures with parents and administrators, so that they can begin to understand how teachable moments can be harnessed to help prepare young children for the transition to kindergarten and success in the larger arena of life.

Soon, the stores will be filled with crisp, delicious fall apples, which will give rise to many of their own teachable moments, beginning with the letter “A.”  But today we have tomatoes, so we’re seizing the moment to harvest, sort, count, compare and investigate nature’s bounty!

It is only through genuine interactions and availability that teachers can identify these moments and act accordingly and spontaneously. Teachable moments require you to “think on your feet” and be flexible enough to stray from your planned path. If children’s interests take them in a direction that you hadn’t anticipated or planned for, you have to be ready to seize the moment and use it as a gift. Follow the joy of your students and your curriculum will develop organically!

“Look how many tomatoes are growing on this one vine!” Owen exclaims to his friends.

We are now collecting data and comparing attributes. Spontaneous discussions unfold as the children explore topics such as where the sun shines in the morning and which tomato plants get the most sunshine.

But how do the tomatoes ripen and turn red under all of those leaves? By observing, investigating and learning that living things grow and change, the children are building a strong foundation for future learning in earth science and life science.

We keep it simple. This type of learning is always developmentally appropriate because the children’s investigations are guided by each individual’s level of brain development.

“Avery, don’t eat them all!” cries one child as Avery pops a couple of freshly plucked tomatoes into her mouth.

We are exploring the concept of “many vs. few.”  But some of the children are too young to care about this concept and just want to experience the sweet deliciousness of a ripe tomato straight from the vine.

Our tomato harvest has all of the hallmarks of a true STEM learning adventure: investigation, discovery, collaboration and discussion. The children are learning through their senses: the visual task of surveying the tomato plants and comparing and categorizing the tomatoes as unripe (green or pale orange) or ripe and ready for harvest (deep orange); the tactile pleasure of separating a plump ripe tomato from its green stem; and the delicious sensation of biting into a tomato, still warm from the sun, and feeling it explode on the tongue. All of the goodness of nature and little brains in motion!

While two-year-old Lauren is more focused on picking the tomatoes and filling her bowl, some of the preschool-age children are busy trying to collect as many as possible. “Look how many I have!” squeals Linnea. “I have more than you!”

As the children explore the physical properties of the tomatoes, we are suddenly counting, estimating, comparing attributes and organizing by color and size. We have vocabulary and math flowing off of the children’s lips, which are stained with the juice of the ripe tomatoes. We are meeting our early learning standards—and the children are developing their own curriculum as they go!

Children construct their own understanding of the world when we provide them with a rich learning environment (in this case, our tomato garden) and ample time to explore, discover and investigate. We want children to think for themselves and not simply follow a preconceived curriculum or theme.

By taking advantage of authentic learning experiences in sensory-rich environments, we are setting the stage for the natural integration of early learning standards and successfully incorporating STEM knowledge into the daily lives of our early learners.

When you foster the development of a creative learning environment where children can find joy in learning, you will discover that your curriculum and lesson themes will spontaneously arise. In other words, let the children lead and the curriculum will follow!

Once the children have “followed their bliss,” introduce the books and thematic materials that support their interests. Build on their energy, enthusiasm and inquisitiveness.

If you head to the tomato garden, I think you’ll agree: early childhood STEM education has never tasted so good!

“LOOK! We have icicles!”

“Can I have one?  I need one!”

On this brisk winter morning—much to the children’s delight—nature has given us the gift of icicles. The children’s fascination with these frozen treasures leads to an abundance of “teachable moments” as we engage in some STEM learning while getting some fresh air and exercise.

Soon we are counting, sorting and measuring the icicles. I can practically see those little brain synapses firing as the children use their senses to investigate the properties of the icicles and revel in the joy of being able to choose, hold and taste their STEM lesson for the day.

“My icicle is longer than yours!”

“I like the little icicles! They fit in my mouth better!”

“I like the thick ones, they last a long time! Look how fat mine is!” 

When I hear my students discussing size, comparing attributes and sharing their math vocabulary with their friends, my heart just soars. Mathematical language is one of the strongest predictors of children’s early mathematical success. Whenever children discuss relative concepts, they are doing math!

“Aww! I dropped mine and now it is in little pieces!” Janelle wails, holding back tears.

“They still taste good!  Now you just have lots of icicles!” says the ever-optimistic Claire. “Before you had one, but now you have more! You have 1, 2, 3, 4, 5!  You have five icicles!”  

Claire touches each icicle as she counts. The ability to count in sequence and use one-to-one correspondence to determine the number in a set is known as rational counting.

Janelle has the ability to rote count, reciting the sequence in the correct order without an understanding of one-to-one correspondence or the concept of cardinality (the number of elements in a set). “I do have five!” she shouts.

“Look, I can drop mine and it doesn’t break!” yells Owen as he drops the thickest icicle to the sidewalk, only to have a few pieces chip away.

It is difficult to ask children to compare quantities if they don’t know what “more” or “less” means. If they can understand “before” and “after,” they are more likely to know, or be able to understand, what number comes after four. When children learn this language in a math context, they are ready to move on to more advanced mathematical concepts. We are building our math foundation!

“How did you make these icicles? We don’t have them at my house,” asks Rowan as she chomps on her icicle. 

“I know!” chirps Robyn. “When the sun warms up the snow on the roof it melts and turns the snow into water and the water starts dripping and then it gets cold again and makes an icicle! “

We take a long look at the ice melting off of the neighborhood roofs and other inclines and see that the dripping has indeed created icicles. We discuss how warm temperatures melt the snow and that is why our clothes often get wet, even when the snow is frozen solid on the ground. Now we have science! I love it when our play leads us right down the path to new STEM experiences and investigations.

“Oh, when our hands are warm in our mittens, it melts the snow? I never knew that!” Logan has processed the information in a way that many of his younger friends don’t have the brain development to do. He seems quite astounded by this realization. Together, we hypothesize which icicles will melt faster or whose icicle will get eaten faster.

Then we swap out our wet mittens for dry ones and hunt for more ice to expand our STEM  vocabulary.

Discussions about the weather are often rote and meaningless in early childhood classrooms. Classroom activities that involve calendars and weather patterns can be boring for young children because they are removed from the actual seasons and weather events.

But bringing the children outside to experience the weather firsthand or bringing the snow inside to be investigated on a water table is interesting. Involving the children in hands-on investigations is a much better way to teach concepts such as “winter” or “cold” than directing a child to walk over to a window and report that “It is snowing outside.”

During this busy holiday season, give yourself and your students a chance to escape the heated classroom and venture into the great outdoors to breathe in some fresh air and find your curriculum in the natural world.

I promise you that this approach will lead to far more STEM learning than talking about the weather during circle time!
