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.

Getting started You need

Getting started You need to compare how well each material can be seen. Make a dark space by drawing curtains, working in a corridor or other dimly lit area, to help you see the difference between good and bad light reflectors. Which materials can you see the best? What difference does having more light make? What can you see in complete darkness? Do some colours work better than others? 2/2 Test your ideas Make a table to record your results. Material How well does it reflect? Complete darkness A little bit of light A lot of light Shiny material White material Dark material Share your ideas How did your investigation go? Was there anything you could have improved about your test? Why not design something for Cosmic and Gem to wear? Extra things to do Find out if you can see reflectors in total darkness. Design a warning poster to help children to be safe at night. British Science Association Registered Charity No. 212479 and SC039236 12

Uncle Astro Cosmic Gem Confusing Cans Organiser’s Card About the activity This activity is designed to get children thinking about weights, ramps and investigation. Gem and Cosmic want baked beans for lunch but Uncle Astro’s cans don’t have any labels! Gem thinks that they can roll the cans to find out what is inside them. Through this activity you will support children to: • Think about how to find out what is inside a can without opening it • Conduct an experiment to find out what is inside various cans • Record and present their results. Kit list • A can of tinned tomatoes, soup, baked beans, cat food for each group, labels removed and marked with different numbers or colours • A set of cans with labels for comparison • Boards/trays to make the slopes plus blocks/ books to support it • Metre rulers, tape measures and other distance markers • Can opener What to do 1. Introduce the activity using the story. 2. Give out activity cards and equipment to the children. 3. Explain that they will be exploring how to find out what is inside the tins without opening them. 4. Encourage children to discuss their ideas and how to carry out their investigations. Discuss how they might make the cans roll. Can they make it a fair test e.g. using the same slope or letting go of the cans rather than pushing them from the top etc. 5. Support children to conduct their investigation and make their own records of their results. Let them explore the unlabelled cans first. Then roll the labelled cans to make a comparison. Ask them to use their observations to predict which of their cans contains the beans. Talk about the distance each can rolled and what is inside it. Can they see a pattern? Let the children try rolling other things to see if they fit the pattern. You could open the chosen cans. 6. Ask the children to present their findings to the rest of the group, they can be as creative in their presentation as they want. 13
