Activity Ideas for WWF Earth Hour

Modified: May 22, 2025 · Published: Mar 19, 2016 by Emma Vanstone · This post may contain affiliate links · Leave a Comment

WWF’s Earth Hour is an environmental campaign where people around the world turn their lights off for one hour to raise awareness about our fragile climate.

Earth Hour is not about how much energy is saved during the hour but about highlighting the issues facing our planet and inspiring millions across the world to live more sustainably.

Activity Ideas for Earth Hour

I’ve put together a few activities to introduce children to renewable energy sources and pollution, as well as nighttime nature ideas.

Solar Powered Cars

Learn about renewable energy with a solar powered car from Teach Beside Me. This is a fantastic hands-on engineering project and a brilliant way to learn about solar panels.

How to make a solar powered car

Wind Powered Cars

Harness the power of the wind with wind powered cars from Housing a Forest. These are great for a team-building STEM challenge.

Solar Oven

Learn about the power of the sun with an easy solar oven and make a delicious dessert at the same time!

Water Pollution Demo

Create a visual display of water pollution using rubbish and food colouring in a jar.

More easy activity ideas for Earth Day

Bury an apple and part of a plastic bag outside and monitor how long each takes to degrade.

On a clear night, sit outside and look at the stars.

Can you think of any more ideas for us?
