This year's theme 

Each year has a different theme and this year the theme will be Strength in Nature. We'd like to encourage children to think about animals, plants and extreme weather conditions that illustrate strength on Earth.

This year's theme is supported by a host of environmental organisations and individuals including National Geographic Kids, singer and songwriter Lemar, illustrator Nick Sharratt, artist Alexandra Baily and explorer and naturalist Steve Backnall. 

To help inspire your group we've also developed free downloadable educational resources which further explore the Strength in Nature theme.
