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.

Goodbye Old Tree

Goodbye Old Tree Organiser’s Card About the activity This activity is designed to get children thinking about trees, and the different materials we can get from trees. The Treedwell local government want some ideas on what to do with in old tree once it dies. Can the children come up with any good ideas? Through this activity you will support your group to: • Research the possible uses of different parts of a tree and decide which they think are the most appropriate and interesting. • Create a story about the life of the tree. • Record and share their research and ideas. Kit list Access to the following will be helpful: • Paper • Pencils • Access to the internet What to do 1. Introduce the activity using the story. 2. Give out activity cards to the children. Encourage the children to think about all the things they know that are made from trees e.g. paper, wood, leaves, etc. 3. Support children to conduct their investigation and make their own records of their results. Encourage the children to do their own research using the internet or by reading books. Let them talk together about what they have found out. If children need help you could get them to look at how wood is used to help wild animals (e.g. bee, bird and bat boxes), or point them towards wooden items that could be used in the town (e.g. benches and sculptures made from wood) 4. Ask the children to present their findings to the rest of the group, they can be as creative in their presentation as they want. They could create a collage using the different tree parts or take bark or leaf rubbings.

Things to think about There is no right or wrong answer for this challenge Keywords • Trees • Nature • Recycling • Wood Find out more Show them art work made from leaves etc. Examples can be found at Help them find out more about how letting the wood rot supports biodiversity (e.g. the range of animals and plants that live in log piles).
