The Limit Less campaign

Mimi’s Rainbow Adventure is part of the IOP’s Limit Less campaign, to support young people to change the world and fulfil their potential by doing physics.

Doing physics can open up a huge range of opportunities but, unfortunately, too many children are told that there are limits to who and what they can be when they grow up.

As parents and carers, you have a vital role to play in making sure that your child can fulfil their potential. By having conversations about science and taking part in activities together, you’re helping to give your child a great start as they begin thinking about what they want to do to change the world for the better.

Find out more and join the campaign.
