Primary challenges (ages 5-11)


Typically completed by 5-11 year olds (Key Stages 1 and 2), CREST Star and SuperStar challenges relate to everyday experiences.

The activities are designed to be easy-to-run and low-cost, and you don’t need to be a teacher, have a science background or have access to specialist equipment to run them. Children are eligible for a CREST Award after completing eight of the challenges and you’ll find helpful hints and tips in each pack for you to use, explaining the scientific themes and offering guidance on conversation topics for your children.

There are many more CREST resources which have been developed by our partners and by providers in your region. Click here for links to CREST accredited resources developed by partner organisations, CREST accredited schemes and education providers who can deliver CREST accredited activities.

Discovery Bag Activity

Discovery Bag Activity Card Cosmic It is nearly the end of the long summer holidays. Cosmic and Gem are bored. Uncle Astro I’m so fed up! I’ve played all my games and read all my books and there’s nothing else to do. How about I make you a discovery bag? That should keep you busy for a while. Aunt Stellar The children love Uncle Astro’s mysterious ‘discovery bags’. Each one is filled with a collection of interesting things to investigate and explore. Oooo a discovery bag, what fun! I wonder what’s inside? Your challenge What has Uncle Astro put in the special bag for Cosmic and Gem to explore? They think the bag has parts of trees inside but they are not sure. They want to find out more. Can you help Cosmic and Gem explore what’s in the bag and decide where all the things have come from? Aunt Stella thinks they are all parts from one tree Cosmic thinks they are all parts from different trees Gem thinks some of the things in the bag are not from trees at all

Discuss How will you find out whether all the things have come from trees? Have you seen trees growing? Where have you seen them? Do they all look the same? What else can you find on a tree? Getting started Use the magnifying glass to look at each thing carefully. What can you see? Are some things the same and some different? Test your ideas Group together the things that you think come from trees and those that don’t. You can use a tree guide or pictures to help you. How many trees do you think there are? Where do you think each tree might grow? Does everything come from trees? Share your ideas Draw a picture of what you think one of the trees may look like. Make a picture of a tree using your tree parts. Make some tree or bark rubbings. Extra things to do Can you think of any other ways of finding out about trees? See if you can find any of the trees growing nearby. See if you can make your own tree discovery bag. Investigate animals that make their homes in the trees.
