Celebrate Earth Day with These Classroom STEM Activities

Earth Day, celebrated annually on April 22nd, offers the perfect opportunity for teachers to engage students in STEM activities that focus on the environment and sustainability.

As educators, one of the best ways to promote environmental awareness to students is through hands-on STEM activities in the classroom. These activities provide a great opportunity for students to explore the natural world, understand environmental challenges, and develop solutions. In this article, we will discuss five exciting STEM activities that can be easily incorporated into your classroom to celebrate Earth Day.

Carbon Footprint Explained to Kids

Explaining the concept of carbon footprint to kids may seem like a hard task, but once you bring in a list of daily activities and explain how they harm the environment the idea of carbon footprint becomes much clearer. 

A simple, general explanation of what carbon footprint is, is the amount the carbon dioxide produced as a result of our daily activities. Carbon is a greenhouse gas, that traps the heat from the Sun and stops it from escaping into space. This makes the Earth warmer, causing global warming. 

Here is a list of daily activities to discuss in class – driving a car instead of taking public transport or carpooling; wasting energy at home, for example leaving the lights when you are not in the room, or leaving electronics on; throwing out leftovers/ wasting food; not recycling garbage. 

Once you have talked about a few examples of what contributes to the carbon footprint, the challenge for the kids would be to come up with solutions and specific actions that lower our carbon footprint and create a poster about it. Divide the class into groups so the kids can discuss and have fun drawing together. 

Mystery Bag Recycling Challenge

Each student is given a brown paper bag that is labeled a “mystery bag” and tasked with filling it up with recyclable items they find at home or in their neighborhood. The first part of the challenge is to collect as many recyclables as the bag can fit, for example, plastic bottles, paper, cardboard, aluminum cans, and more.

The next day, the students return the bags to school. Students reveal the recyclables they have collected and place the bags at the “recycling station” table. Then each student chooses a random brown bag and has to design a device that can create renewable energy. Let your students’ imaginations run wild and see what crazy inventions they come up with.

Plant a Classroom Garden

One of the best ways to connect students with the environment is by planting a classroom garden. This hands-on activity encourages students to learn about plant life cycles, photosynthesis, soil composition, and the importance of pollinators. Students can grow vegetables, herbs, or native plants, and track their growth over time. This project can be adapted for various age groups, with older students delving deeper into topics such as sustainable agriculture and the impacts of climate change on plant life.

Create a Rainwater Collection System

Teaching students about water conservation is crucial in today’s world of increasing water scarcity. By creating a simple rainwater collection system, students can learn about the water cycle, water conservation, and sustainable resource management. Using recycled materials such as plastic bottles or buckets, students can design and build a system to collect and store rainwater. This water can then be used to water the classroom garden or for other non-potable uses.

Build a Solar Oven

Teaching students about renewable energy sources is essential in raising awareness of the need for sustainable energy practices. A fun and engaging way to introduce this concept is by building a solar oven. Using simple materials such as cardboard, aluminum foil, and plastic wrap, students can construct a solar oven to cook s’mores or other treats. This project allows students to explore the principles of solar energy, heat transfer, and insulation while demonstrating the potential of renewable energy sources.

Celebrating Earth Day with STEM activities in the classroom helps students develop a deeper understanding of the environment and the importance of sustainable practices. These activities promote critical thinking, problem-solving, and collaboration while fostering a sense of stewardship for our planet. By integrating Earth Day-themed STEM activities into your classroom, you can inspire the next generation of environmental leaders and innovators.
