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.

Tree Trouble Activity

Tree Trouble Activity Card Save the tree There’s a dilemma in Treedwell about an old tree: The local government think we need new houses in the town, but the old tree is on the site. The builder says he wants to cut it down. keep our shade Protestor 1 thinks if they cut the tree down, there will be nowhere for animals to live and it will affect the local biodiversity. Protestor 2 thinks we need the shade from the tree to sit in when it gets hot. Do you think the old tree should be chopped down? Your challenge Find out whether it makes a difference to animals and plants if a tree is chopped down. Discuss What do you think biodiversity means? What sorts of wildlife would you expect to find on and around a tree? Are plants wildlife too? Do you need to look at lots of trees or is one tree enough?

Getting started Some fellow investigators have had some ideas to get you started: If we lay a large sheet under the tree, we could gently shake some of the branches and catch what falls out. Then we could find out about what we have caught. We could see how much shade a tree makes and find out whether there are more plants and animals in its shade than in the open. We could use the internet to look up what types of plants and animals might live around a tree. By sitting quietly and watching the tree, we could see what types of animals come near it. Test your ideas Does a tree have any life on and around it? If so what kinds? Do you think it is the same for all trees? How would it affect plants, animals and people if an old tree was being cut down? You might like to record your results like this: Living thing Would it be effected by cutting down the tree? E.g. Squirrel It would have nowhere to climb and hide Share your ideas Write a report to Treedwell’s local government and explain what you found out. You could include some bar charts or drawings to help explain. The town needs new houses, so do you think it is a good idea to cut down the tree? Why? Produce a poster to convince other people.
