5 Climate Action Kit and micro:bit Projects to Celebrate Earth Day

Earth Day isn’t just a moment—it’s a movement.

Since 1970, Earth Day has united people around the world every April 22 to promote environmental protection. Now in its 55th year, the 2025 theme, “Our Power, Our Planet,” calls on all of us to accelerate the shift to renewable energy and a cleaner, more sustainable future.

At Forward Education, we believe the power to protect our planet starts in the classroom. Through hands-on coding and robotics, we empower students to explore real-world climate challenges, discover purpose-driven careers, and build a better world—one project at a time.

To celebrate Earth Day, we’re sharing five of our favorite Climate Action Kit and microbit projects that align with this year’s theme. And if you don’t have the Climate Action Kit yet? No problem—we’ve included microbit-only alternatives so every student can join the movement.

1. Designing a Sustainable Smart Home

Grades: 6–8
Time: 60–75 mins
Theme: Sustainable Cities
Career Profile: Urban & Regional Planner
Urban and Regional Planners manage land use and help design sustainable communities. Their work supports eco-friendly infrastructure, housing, and transportation systems.

Project Overview:
Students build an automated smart home using sensors to save energy by adjusting lights and temperature based on environmental changes.

💡 Try This with Just a micro:bit:
Create a temperature alert system using the micro:bit’s built-in temperature sensor. Use the LED screen to show temperature levels and simulate thermostat control with buttons A and B.

2. Wind Energy in Action: Generating and Storing Power

Grades: 6–8
Time: 45–60 mins
Theme: Renewable Energy
Career Profile: Renewable Energy Engineer
These engineers design systems to harness wind, solar, and other clean energy sources, helping reduce our dependence on fossil fuels.

Project Overview:
Students design a wind turbine that generates and stores renewable electricity for later use.

Two students working on the Wind Turbine Climate Action Kit project in front of a computer.

💡 Try This with Just a micro:bit:
Use the accelerometer to simulate wind rotation. Attach the micro:bit to a spinning cardboard “turbine” and display a simulated energy meter on the LED screen.

3. Smart Streetlights for Sustainable Cities

Grades: 3–5
Time: 45–60 mins
Theme: Sustainable Cities
Career Profile: Street Lighting Engineer
These engineers design smart lighting systems for safe, energy-efficient cities—often integrating motion sensors and low-energy LEDs.

Project Overview:
Students build a motion-activated streetlight that turns on only when needed.

💡 Try This with Just a micro:bit:
Use the micro:bit’s light sensor to detect darkness and trigger a light bulb icon on the LED screen. Add motion detection using a shake event to simulate a person walking by.

4. Harnessing the Sun’s Energy with Solar Panels

Grades: 6–8
Time: 45–60 mins
Theme: Renewable Energy
Career Profile: Renewable Energy Engineer
They plan and manage the development of solar, wind, and geothermal systems—analyzing energy needs, optimizing systems, and ensuring environmental sustainability.

Project Overview:
Students create a solar panel prototype that senses and tracks the sun for maximum efficiency.

💡 Try This with Just a microbit:
Use the micro:bit’s light sensor to detect the brightest light source. Rotate the micro:bit and display directional arrows on the screen pointing toward the strongest light.

5. Smart Warehouse Vehicles for Industrial Efficiency

Grades: 11–12
Time: 45–90 mins
Theme: Smart Vehicles
Career Profile: Civil Engineer
Civil Engineers design and manage infrastructure—from roads to energy-efficient buildings. They play a vital role in building sustainable industry systems.

Project Overview:
Students build an autonomous warehouse vehicle prototype to explore automation, energy efficiency, and smart logistics.

💡 Try This with Just a micro:bit:
Create a delivery simulation using the compass. Press buttons to "send" the vehicle in specific directions (e.g., North = pickup, South = drop-off), and use LED icons to show delivery status.
