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 one 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.

RECYCLE REUSE Recycle Reuse Activity Card Paper was first created in China by Ts’ai Lun in A.D. 105. He mixed hemp, mulberry bark, and rags with water, mashed them, pressed out the liquid and hung it to dry. This humble idea has allowed people around the world to communicate ideas, share news and create works of art. But paper production has a major impact on the environment. It’s time to take action! You can help by recycling. RECYCLE REUSE Your challenge Find out more about recycling paper and make your own paper by recycling waste paper. Discuss Why do you think it is better to recycle paper than to throw it in waste tips? If you look at different types of paper with a magnifying glass or microscope, what can you see? What kinds of paper do you think you could recycle?

RECYCLE REUSE Getting started Tear old paper into small pieces, put in a bowl, cover with warm water. Mash or whisk until it is like thick porridge. Make a frame from a coat hanger and old tights. Dip your frame into the liquid and make sure it is evenly covered with pulp. Let the water drip back into the bowl. Put the coat hanger down on absorbent paper or cloth. Leave to dry. To speed up drying, put another piece of paper or cloth on the top of the pulp and roll firmly with a bottle or rolling pin. Ironing it will help too. Ask an adult to help. Your paper needs to be left to dry for at least a day before you try to write on it. Test your ideas Make a plain piece first, then try different ideas. You could add colouring, seeds, glitter or other tiny items to your paper as you mix it. You could put leaves, buttons, pieces of string or other interesting things on top of your paper to make patterns. Share your ideas Look at the different papers that have been made. How will you change what you do next time? You could make a display of the finished paper. Extra things to do How strong is your special paper? Find out how much paper you use each day.
