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.

Be Seen Be Safe

Be Seen Be Safe Organiser’s Card About the activity This activity is designed to get children thinking about reflection and light. Children are asked to help Cosmic and Gem find out what materials will help railway workers be seen in the dark. Through this activity you will support your group to: • Test different materials to see how reflective they are • Test to see if other variables make a difference to reflectivity • Record their results and share them with the group. Kit list You might ask children in advance to bring things that they think will help them to be seen in the dark. • A selection of different materials e.g. different coloured T-shirts or fabrics, reflector armbands, foil, shiny paper, black paper, dark/light coloured objects • Torches • A place that you can partially blackout What to do 1. Introduce the activity using the story of Cosmic and Gem. Ask the children what they think will help people to be seen in the dark. Give out activity cards and equipment to the children. 3. Explain that they will be using the equipment provided to test the best way to be seen in the dark. 5. Support children to conduct their tests and make their own records of their results. 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. 4. Encourage children to discuss their ideas and how to carry out their investigations. Prompt questions: • What materials will they test? • How will they test to see if they are reflective? • How will they make sure their test is fair? • How will they record their results?

Things to think about Some things produce light, e.g. a lamp, the Sun. We call these light sources. Other things can reflect light, but they don’t produce light of their own, e.g. a mirror, aluminium foil, a white T-shirt. We call these reflectors. Some colours reflect more light than others. White is easier to see than red; red is easier to see than black. Reflectors will be seen if there is a source of light. Even on a ‘dark’ night there is usually light around, especially in towns. A good reflector may be visible on a dark night because of this. Cat’s eyes and reflective strips will also reflect the lights of cars. So people will need to wear something light coloured or shiny to be safe in the dark. Keywords • Reflection • Source • Light • Safety Watch out! ! Make sure that children are not wandering around in the dark with sharp objects. Make sure that the area is cleared of obstacles and dangerous substances
