World Environment Day 2025: Activities and Resources for Schools

May 29, 2025

What is World Environment Day?

World Environment Day, celebrated on June 5th, is a global event organized by the United Nations to raise awareness about environmental issues. It is the largest global platform for environmental public outreach, celebrated by millions of people across the world.

The theme for 2025 is #BeatPlasticPollution, focusing on driving momentum to 'refuse, reduce, reuse, recycle and rethink' plastic use. In this blog, we offer a variety of activities and resources to help schools participate and educate students on how to #BeatPlasticPollution.

Purple Mash activities for World Environment Day


Rubbish and Recycling

Start the learning in your classroom by reading What a Waste: The Problem with Rubbish with your students. The quiz would also be a great whole-class activity to work though. Then, children could create a Recycling Poster to put up around the school. Older children might want to take part in a Recycling Debate, while younger students could explore the recycling activities in Simple City.

Refill to Stop Landfill - NEW refillable glue sticks!

Make a positive environmental impact in your classroom this World Environment Day with new Purple Mash refillable glue sticks! We've teamed up with U-fill, creators of the world's only refillable glue stick system: instead of throwing out empty glue sticks, you can simply refill them with U-fill canisters - again and again.

They're also purple! They've been designed especially for young learners, allowing them to clearly see where they've applied the glue. It dries clear, but the visibility during use makes it easier, neater, and more fun to get creative.
