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.

Perhaps one of your readers could give us some advice.” Your challenge Can you help them to decide the best design for a raft? You can make models out of paper. What shape of raft will hold the largest number of objects before it sinks? You can only use one sheet of paper at a time. Discuss What do you know about rafts? Have you ever made one? What shapes do you think might make good rafts?

Getting started You can use sheets of squared or A4 paper to make your models. You can make the paper into a raft by bending up the sides and folding the corners. Fasten the corners. Don’t cut your paper. What different shapes and sizes can you make by folding your pieces of paper in different ways? Test your ideas Put your raft to the test! See which shape holds the most objects without sinking. What’s the best way to add the objects? Which raft do you think will win and why? You could record your results in a table like this: Picture/ description of raft Maximum number of marbles before sinking Raft 1 Raft 2 Raft 3 Share your ideas You could make a model of your best raft to send to Natty Nodrum. Extra things to do Would it matter if you use different types of paper? Could you make the raft without fasteners? What other materials can you use to make a raft?
