Nature is good for kids in so many ways. Yet some studies suggest the amount of time they spend outdoors has dropped 50% in a single generation. Earth Day, celebrated on 4/22 and intended to raise awareness of environmental issues, is an ideal moment to connect kids with nature while building scientific thinking skills.
That’s important for many reasons. It sharpens curiosity and critical thinking, but scientific thinking also helps develop resiliency by encouraging trial and error. And science is best learned through hands-on discovery. The good news? Meaningful science learning can happen anywhere, no lab required!
Hand in hand with science, outdoor play supports observation, problem-solving, exploration, and creativity. Parents and teachers: keep reading to find simple and fun activities for kindergarten through fourth-grade learners to help them explore science outside the classroom.
Why outdoor science learning matters
Few activities match the benefits of outdoor science education. Green Schoolyards America suggests, “Outdoor learning helps students become better communicators, more engaged learners, and flexible problem solvers,” also noting that it improves academic performance across the curriculum.
Science exploration for children in the great outdoors:
• Promotes better physical and mental health
• Creates opportunities for social interaction and collaboration
• Helps teach appropriate risk-taking
• Supports the development of STEM skills.
• Builds real-world connections with classroom and at-home learning
Activities to help kids get excited about the outdoors
Despite those many benefits, a combination of factors, including screen time, parental concerns about safety, and busy activity schedules, work against getting kids outside—to the point that the natural world can almost feel unnatural!
1. Nature Scavenger Hunt for Budding Scientists
Older kids often create projects like leaf or insect collections for biology classes, but similar outdoor science activities for kids can work for kindergartners through fourth-graders. Help children search for natural objects while practicing classification and observation skills.
Here are a few how-tos:
• Create a checklist (could be a picture board or a written checklist, depending on age) of leaves, rocks, insects, flowers, or textures - make your own or find many templates online for free to download
• Practice sorting by color, size, or type
• Introduce vocabulary like “living” vs. “nonliving”
• Encourage drawing or journaling their discoveries
• Adapt difficulty by age group
Nature scavenger hunts nurture a love for the environment, encourage physical exercise, and, if done in a group, promote teamwork. They also reduce stress, boost sensory awareness, sharpen observational skills, and stimulate creativity.
2. Mini Weather Station
Kids are probably most interested in the weather when hoping for a snow day off from school or sunshine for an outdoor game or party. They might also be a little—or a lot—afraid of thunder and lightning. But building their own weather station could crank up their overall weather curiosity! It lets kids observe daily weather patterns and learn basic meteorology concepts. Little Bins for Little Hands provides one version with description, materials lists, and how-tos, and My NDNA offers another.
Building and using a weather station encourages kids to:
• Track temperature, clouds, wind, rain, snow, and sunlight
• Gather, use, and analyze data
• Discuss patterns over time
• Make predictions
• Practice math skills and vocabulary, like measurement and volume
As a complementary indoor activity, Anywhere Teacher, School Zone’s online learning program for ages 2-8, includes a number of weather-related activities. Of special note are Weather Flash Cards, which teach fun facts about phenomena like wind, rainbows, and thunderstorms.
Studying the weather first-hand could inspire the next generation of meteorologists!
3. Backyard Bugs
Explore insects and small creatures while learning about habitats and ecosystems. Merlin Academy, in "Why Bugs Bug Us," explores the “science behind our fear of bugs” but also suggests that fascination with bugs can actually be a superpower, especially for neurodiverse kids. They note that “The insect world is incredibly diverse, with over one million described species.” Bugs, they say, “offer endless opportunities” for honing highly valued skills like categorization, pattern recognition, and systematic observation, for example, watching the life cycles of different insects.”
During bug-hunting expeditions, be sure to:
• Practice safe observation of bugs using magnifiers
• Practice respectful interaction with wildlife
• Discuss habitats and roles in nature (think bees and ants!)
• Compare insects’ sizes, colors, and movements
Kids can study and apply their learning to bugs in the backyard, a school garden, or a nature trail. Whether bugs send your child screaming in terror or giggling with delight, hands-on learning will increase their excitement, generate curiosity, and develop some math and logic skills if comparing and tracking the bugs. Familiarity might even reduce the fear factor!
With insects too, Anywhere Teacher helps hands-on learning take flight indoors with Insect Flash Cards! Kids discover fun facts about a weevil, ladybug, mosquito, and many more bugs. And the Exploring Nature life cycle video series includes “The Life Cycle of Butterflies.”
4. Sink or Float Science
A simple experiment using outdoor materials can amuse kids as they learn important lessons about mass, density, and buoyancy. The National Day Nurseries Association (NDNA), based in the U.K., notes that a simple sinking or floating activity “encourages children to experiment with sinking and floating by testing different objects in water.”
Here are basic how-tos:
• Collect natural objects (sticks, stones, leaves)
• Make predictions before testing - will it sink or float?
• Discuss density in simple terms
• Compare results and patterns
• Encourage hypothesis and reasoning skills
This fun, simple activity promotes critical thinking as children make predictions, test hypotheses, observe results, and develop vocabulary. Watch their confidence and curiosity grow, too.
5. Shadow Tracking
What child isn’t fascinated by shadow play on walls and ceilings? Taking it outside makes it a dynamic science lesson. The Exploratorium, a museum and public learning lab in San Francisco that intertwines art and science, notes the simplicity of it: “In order to create a shadow, you need three things: light, something blocking the light, and a surface for the shadow to fall on. A shadow is an area where light is being blocked.” Around those basics are opportunities for multiple lessons. And the only tools and materials needed are a sunny day, chalk, a safe surface to write on, and a buddy! Their Science Snack Outdoor Shadows page offers multiple ideas.
In general, follow these basic steps:
• Trace shadows of different objects at different times of day using chalk
• Observe how shadows move and change size
• Discuss the sun’s position
• Connect to the time and the rotation of the Earth
• Try to predict where the shadow will move next
This activity combines science with drawing or measurement, and kids will also learn about spatial awareness, shapes, sizes, and dimensions.
6. Building Outside
Multiple generations have enjoyed building forts and hideaways. Seldom do we consider that these activities introduce early engineering skills! A Facebook page for TimberNook, a nature-driven school program, suggests, “There are endless benefits to building forts with other children!” adding, “From much-needed sensory input to boosting teamwork, problem-solving, and confidence, fort building works on every aspect of child development.”
Here are a few ways parents and teachers can up the construction game without disrupting the fun:
• Urge kids to build shelters, dens, or bridges using natural materials
• Encourage teamwork and problem-solving
• Help them test strength and stability
• Discuss trial and improvement processes
• Connect to STEM and real-world engineering (what might their fort share in common with castles and skyscrapers?)
7. Plant Growth Experiments
An excellent way to pair time outside with science lessons is to teach plant biology through planting and observation activities. Learning about plants’ essential needs, such as light, water, and soil, develops environmental awareness. It also enhances sensory and fine motor development as well as cognitive growth and can be a starting point for discussing food and nutrition. Why are vegetables good for us?
To get started:
• Plant seeds in soil or recycled containers
• Observe changes daily or weekly
• Discuss sunlight, water, and nutrients
• Measure plant growth over time (it’s a great way to introduce charts and graphs!)
• Record findings in a learning journal
Watch this quick video from Quality Start Los Angeles that encourages celebrating Earth Day with little ones by germinating seeds in a clear jar, on a damp paper towel, watching it grow, and then about two weeks later, transplanting the seedling outside.
Keep the learning going with Anywhere Teacher’s “The Life Cycle of Apple Trees,” one of the online program’s four Exploring Nature life cycle video series.
8. Stargazing Fun
Notable individuals throughout history, from diverse walks of life, have marveled at the night sky and its ability to inspire both awe and joy. Cartoonist Bill Watterson poignantly observed, "If people looked at the stars each night, they'd live a lot differently." Backyard stargazing, whether learning the location of the Big Dipper or seeing Jupiter lined up with the moon, creates great memories. It is also an opportunity to introduce concepts such as the solar system, moon phases, and gravity.
To get kids looking skyward:
• Set up a backyard “camp” with blankets, chairs, or comfy cushions.
• Use apps to help identify constellations or specific stars in the sky.
• Use standard binoculars to look at the craters on the moon, or a telescope for exploring the moon and stars in more detail.
• Make star journals, where children draw the constellations they see, note the moon's shape, and record the date and time of their observations.
These types of activities introduce young children to astronomy principles, encourage critical thinking and observation skills, and can reduce stress.
Kids can continue exploring space with Anywhere Teacher’s Space Flash Cards, which provide definitions and fun facts for terms that include galaxy, planets, asteroid, and many more.
Make outdoor science part of everyday learning
The big takeaway for families and educators? View outdoor spaces as powerful “classrooms”! Earth Day activities help focus attention on the environment and natural world, and a little “science in the backyard” changes up routines and builds curiosity and confidence. It could even spark a passion that kindles a future career!
Science experiments are not all about Petri dishes and Bunsen burners. Small activities for school-aged kids can create big learning, especially when we keep in mind that asking questions is more important than giving perfect answers.
