Primary challenges (ages 5-11)


Typically completed by 5-11 year olds, CREST Star and SuperStar challenges relate to everyday experiences. Children complete eight activities to gain a CREST Award, with each activity taking between 45 minutes and 1 hour to complete.

The activities are designed to be easy-to-run and low-cost. You don’t need to be a teacher, have a science background or have access to specialist equipment to run them. The packs contain helpful hints and tips for you to use, explaining the scientific themes and offering guidance on conversation topics for your children.

There are more CREST approved resources that have been developed by our partners and providers specific to your region.

Useless Umbrella

Useless Umbrella Activity Card Aunt Stella is in a tizzy. She has been invited to a party at Buckingham Palace. “Wow!” say Cosmic and Gem. “You must be very important.” USELESS UMBRELLA “Have you got a new dress,” Cosmic asks, “and a new hat?” Aunt Stella goes to her wardrobe and pulls out a rainbow coloured dress and a bright purple hat. “You’re going to look fantastic,” says Gem. “Do you have an umbrella too, in case it rains?” Aunt Stella nods and goes to the cupboard and pulls out a huge, rainbow coloured umbrella to match her dress. “Here it is,” she says. “It’s enormous! Can we try it Aunt Stella?” shouts Gem, as she rushes outside to open the umbrella. But it’s raining outside and no sooner has Gem opened the umbrella than drip, drip, drip, rain is tumbling on her head through the umbrella. The umbrella is full of holes! The umbrella is useless. “What am I going to do?” says Aunt Stella. “I don’t have another one.” “Don’t worry Aunt Stella, I am sure we can fix it for you,” says Gem. “We just need to find something waterproof.”

Your challenge Cosmic and Gem need to find something to fix Aunt Stella’s umbrella. What are umbrellas made from? How do they stop you getting wet? Gem thinks they need a sponge to make it waterproof Cosmic thinks they need thick fabric to fix the umbrella Aunt Stella thinks they need brightly coloured, thin fabric to fix the umbrella What do you think? Find the best material to fix Aunt Stella’s umbrella. Discuss USELESS UMBRELLA Talk to your buddy about which material you think will be the best for an umbrella. How do you think you can find out? Getting started Collect some different materials. Put each one on top of a different piece of paper towel. Put one drop of coloured water onto each piece. How much water goes through? How can you make sure the test is fair? Test your ideas Can you think of any other ways to find out? Share your ideas Draw Aunt Stella’s umbrella and stick pieces of the best materials on the picture. Do you think Aunt Stella will like the umbrella? Why do you think that? Is there anything you think you should change? Extra things to do Make a list of other things you might want to keep dry. Here are some ideas to get you started – a rabbit in the garden, your books on the way to the library and shopping on the way home from the shops. Design ways of keeping them dry.
