Earth Day classroom activities give preschool and kindergarten students an early, hands-on introduction to caring for the planet, and they don’t need to be complicated to make an impression. From planting a class garden to turning empty milk cartons into planters, this guide covers simple, age-appropriate projects that fit into a single day or stretch across a full week of lessons.
Below, you’ll find planting ideas, recycled-material crafts, classroom games, and celebration tips. If you’re building out a broader activity calendar, you’ll also find more hands-on project ideas in AlphabetU’s Crafts collection.
Beautify the Earth and Your School
Getting students physically involved in planting is one of the most memorable ways to mark Earth Day, and it scales easily to whatever space and budget a classroom has:
- Start seeds indoors as a class project a few weeks ahead of time, then transplant them outside once they’ve sprouted.
- Partner with a local flower or garden center for donated seedlings if the budget is tight.
- Give each student their own flower or seedling to plant in a shared class garden bed, so everyone has a stake in how it grows.
- No outdoor space? A window box or a few potted plants on a classroom shelf works just as well for teaching the same lessons.
If your class enjoys a garden theme beyond just Earth Day, AlphabetU’s Discovery Garden Complete Prop Set is a fun way to carry that theme into photo props and classroom decor for the rest of the year.
Make Earth Day Crafts with Recycled Materials
Recycled-material crafts double as a lesson in reducing waste, and they’re inexpensive since most of the supplies are things families already have at home. A note home asking parents to save a few items ahead of time is usually all it takes to stock up:
- Milk cartons – Rinse and turn into small planters or simple toy boats.
- Paper towel tubes- Transform into binoculars, rain sticks, napkin rings, or hair accessory holders.
- Soda bottles – Cut and decorate into bird feeders, mini baskets, or toy rockets.
Round out any of these projects with basic craft supplies – stickers, paint, and embellishments – so each piece becomes its own small masterpiece.

Add Earth-friendly Classroom Games and Activities
Earth Day classroom games are an easy way to reinforce the day’s lessons without extra prep, and most can be adapted to whatever space and group size you’re working with:
- Recycling sort – Set out labeled bins and have students sort clean recyclables, trash, and compostable items – a hands-on way to teach the difference.
- Nature scavenger hunt – Send small groups outside (or around the classroom) with a simple checklist of natural items to find, like a leaf, a rock, or something green.
- “Reduce, Reuse, Recycle” relay – Have teams race to sort picture cards of common items into the correct category.
- Earth Day Bingo – Swap numbers for eco-friendly actions – turning off a light, picking up litter, recycling a bottle – that students can check off as they complete them.
These Earth Day activities for the classroom work well because they turn a big idea into something kids can do with their own hands.
Celebrate Earth Day as a Class
A little celebration at the end of the day helps the lessons stick, and it doesn’t have to be elaborate:
- Hand out small awards, favors, or prizes to recognize participation and enthusiasm throughout the day.
- Serve earth-friendly treats or organic refreshments as part of the celebration.
- Decorate the classroom with Earth Day posters and the recycled crafts students made earlier in the day, so the room reflects the day’s theme.
If you’re looking for ready-made ways to recognize students for the day, AlphabetU’s Awards & Recognition collection has options that work well for a quick, low-cost celebration.
Why Earth Day Classroom Activities Matter in Preschool and Kindergarten
Introducing environmental concepts early gives young students a foundation they’ll carry with them well beyond a single day of activities:
- Hands-on projects like planting and recycling make abstract ideas about caring for the planet concrete and easy to understand.
- Group activities build teamwork and communication skills alongside the environmental lesson.
- A yearly Earth Day tradition gives students something to look forward to and builds on what they learned the year before.

Bringing Earth Day Classroom Activities into Your School
Earth Day classroom activities don’t need a big budget or a lot of prep time to make an impact. A simple planting project, a few recycled crafts, and a short game or two are enough to give young students a real sense of what it means to care for the planet. Building in a small celebration at the end of the day helps the lessons stick and gives students something to look forward to each year.
However you shape the day, these Earth Day classroom ideas are an easy, memorable way to bring the holiday into any preschool or kindergarten classroom.

Planting seeds or a small class garden, making crafts from recycled materials like milk cartons and paper towel tubes, and playing simple sorting or scavenger hunt games are all easy, low-prep options for preschool and kindergarten classrooms.
