Primary challenges (ages 5-11)

Typically completed by 5-11 year olds (Key Stages 1 and 2), CREST Star and SuperStar challenges relate to everyday experiences.

The activities are designed to be easy-to-run and low-cost, and you don’t need to be a teacher, have a science background or have access to specialist equipment to run them. Children are eligible for a CREST Award after completing eight of the challenges and you’ll find helpful hints and tips in each pack for you to use, explaining the scientific themes and offering guidance on conversation topics for your children.

There are many more CREST resources which have been developed by our partners and by providers in your region. Click here for links to CREST accredited resources developed by partner organisations, CREST accredited schemes and education providers who can deliver CREST accredited activities.

Rainbow Collectors

Rainbow Collectors RAINBOW COLLECTORS Activity Card It’s a wonderful sunny day. Cosmic and Gem have gone to the park with Aunt Stella. They have had fantastic fun whizzing down the slide. Now they are going on the swings. Suddenly splish, splash, tiny raindrops start to fall. RAINBOW COLLECTORS RAINBOW COLLECTORS “Oh dear,” says Gem. “Oh dear,” says Cosmic. But Aunt Stella simply smiles and points behind them. There across the sky is a rainbow. It is the most beautiful rainbow that they have ever seen. “Wow!” Cosmic and Gem whisper to each other, afraid that if they speak too loudly the rainbow will go away. But then, as quickly as it had started, the rain stops. Gradually the rainbow fades away. Cosmic and Gem look sad. “Don’t worry,” says Aunt Stella. “Look around you. There’s green grass and yellow buttercups. The world is full of colours. You can be rainbow colour collectors and make your own rainbow.” I wonder if they can? Perhaps we can help them. Have you seen a rainbow? Which colours did you see? Do you think that Cosmic and Gem can find all the colours of the rainbow? Your challenge Can you help Cosmic and Gem find all the colours of the rainbow?

Discuss Talk to a buddy about your ideas on how to find all the colours of the rainbow. CTORS Getting started You are going to collect your rainbow on a palette. Look around you very carefully. You might find leaves, flowers and other things. You only need tiny bits of each colour. Stick the bits of colour on your palette. Test your ideas Do you think Cosmic and Gem will find the same colours in spring, summer, autumn and winter? Share your ideas Put all your palettes on display to make a beautiful rainbow. Extra things to do You could take some photographs or draw pictures of the different colours you can see around you. You could make a rainbow scrapbook.
