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.

It has been raining for days, but now, HOORAY, the sun has come out. What a wonderful day for a party! Gem is so keen to get to the party that she skips on ahead. “Wait for me!” Cosmic shouts. But Gem doesn’t hear him, she is too busy dancing along in the sunshine. Suddenly, SPLAT, Gem trips and falls into a muddy puddle. Oh no! Her lovely new T-shirt is covered with mud. What can she do? Luckily MUDDY they are MESS very close to Aunt Stella’s house, so they knock on her door. “Oh dear,” says Aunt Stella, as she opens the door. “What a muddy mess!” “Can you get me clean again for the party?” Gem asks in a sad, little voice. “I am sure there is something we can do,” says Aunt Stella kindly. “We just need to think about it.” Gem thinks the mud will brush off when it’s dry Cosmic thinks we might need soap and water Aunt Stella thinks it will soon rinse out with some cold water Have you ever got your clothes really dirty?
