Using a cardboard box of any size, along with other recyclables you can find and use safely, we challenge you to get creative and bring one of our ideas to life, or go a step further and invent your own project. Download our free activity sheets below.
Secondary school students can try their hand at junk modelling too and why not add a coding element to get your creation moving and talking. No idea is off-limits and we can’t wait to see what you come up with!
Share your amazing ideas with us on social media so we can send them digitally all the way around the world for real inventors to see @IETeducation.
Why not team up with others or run a mini-competition to see who can come up with the most exciting idea.
