The Cracking Ideas competition is open to all 9 and 10-year olds in school, in clubs or learning at home.
Enter as many times as you'd like by completing any one of the four Lesson Plans focusing on sustainable energy - the theme of the new Wallace and Gromit film 'A Matter of Loaf and Death'. You simply submit a photo or drawing/scan of your Cracking Idea.
It’s great fun, and you could win some fantastic prizes, including an original bespoke trophy, created by Aardman.
