There are quizzes to use with your class, and they could also write a letter to the headteacher about ofsetting climate change in the school.

Refill to Stop Landfill - refillable glue sticks!

Make a positive environmental impact in your classroom this World Environment Day with 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.
