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.

SUPER SPINNERS Take it further In this situation, gravity pulls an object towards the Earth, but air pushes against it. Flat paper falls slower than screwed up paper because there is more air resistance. Gravity pulls the spinners down. The air resists the movement and pushes on each blade causing the spinners to spin. Spinners with longer blades will normally spin more slowly. This is because there is more surface area for the air to push against. The material on large spinners needs to be stiff enough to hold the blades in place to allow it to spin. Sycamore seeds are sometimes called helicopters because of the way they spin as they fall. Keywords • Flight • Shape • Size • Aerodynamics Watch out! It can be useful to drop the spinners from a height greater than a child’s height. However, children should not stand on chairs or tables to launch their spinners unless very closely supervised. A library stool or kitchen steps are better. Children need to handle and carry scissors in a safe manner. SUPER SPINNERS British Science Association Registered Charity No. 212479 and SC039236
