Early years and primary – ‘Change and adapt’ poster competition
The theme for 2025 was ‘Change and adapt’, – there are loads of STEM topics to be explored. Pupils could create a poster showing how plants and animals adapt to changing seasons or surroundings, or how humans have adapted to changing technology. They could look at climate change and how we can adapt our behaviours to protect the environment, or their favourite science experiment and how it shows change. The more creative the interpretation of the theme, the better!
What were the prizes?
Prizes for the 2025 competition winners included:
An incredible range of STEM themed books for all ages; subscription to Eco Kids Planet, Okido, National Geographic Kids and Little Kids and Save My Exams; as well as copies of Hoopla and Whizz Pop Bang magazines; memberships to the Mammal society and My Science Club; vouchers for VEX robotics, the Science Museum and a WWF adoption pack; a large selection of games and toys including a plasma ball, MegaWatt games, Play Press kits, Cool Cat Chem Cards, At the museum jigsaw, Knex, Play doh, activity books, BBC microbit, challenge cards, Seedboms, National Geographic gemstone dig kit and sensory science kit, and a Kit box from Curiosity Box; as well as notebooks, mugs, rulers, DIY flashlights, microscopes and even an air purifier for your school!
Prizes may vary by age category and by availability and we reserve the right to make changes to the prizes. Any prize awarded will be split across the team should a poster be submitted by a team.
Secondary special competition category (also open to interested primary pupils aged 8-11). The scientists from UCL need your help!
Choose an indoor public space where you often spend time – this could be an area where you learn, or a place you visit regularly like a library, café or cinema. Do you think the air in this space is healthy and clean? Why? Come up with an idea or invention to change the air in your chosen space, making it healthier to breathe. How will it work? Could it be used in other public places too?

You might have a brand-new idea, or you might come up with something that already exists but re-imagined in a unique or creative way. The researchers at UCL have considered lots of different ideas for improving air quality and preventing the spread of viruses in hospitals. For example, you could think about face masks, curtains and screens, ventilation, fans or air filters.
Then think carefully about how you will lay out and present your idea. You should consider how best to communicate your research so that it is clear and logical. You could create a set of instructions, a detailed diagram or you might like to develop an eye-catching poster!
Entries must be A4 or A3 in size and you’ll need to be able to take a photograph of your work so it can be sent to us online for judging.
Researchers from the team at UCL, alongside members of the British Science Association, will shortlist entries, and a panel of judges will select a winner in each age category. The runners up in each age category will be uploaded to our Facebook page and the public will decide on a ‘popular vote’ winner.
