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.

PLANT DETECTIVE Plant

PLANT DETECTIVE Plant Detectives Activity Card Cosmic is walking along the street to meet Gem at the shops. On the way he notices a plant sticking out of a crack in the pavement. How exciting! Plants usually grow in gardens, not in pavements. How did the plant get there? He thinks that perhaps someone dropped it as they walked along, but who? Cosmic runs to ask Gem to help him solve the mystery. She’s bound to know the answer. Cosmic explains what he has found, but Gem isn’t sure how the plant got there either. She wonders if the plant might have grown from a seed under the pavement, but who could have planted the seed? Cosmic and Gem know they have to look for clues to solve a mystery. They can’t wait to start searching. Aunt Stella loves plants, so she comes to help them. But where will they begin? Can you be plant detectives and help to find clues about plants that grow in unusual places? Where have you seen plants growing? Have you ever seen any plants growing in a pavement? PLANT DETECTIVE Your challenge Become a plant detective and help Cosmic and Gem solve the mystery of where plants grow.

Discuss Talk to your buddy and plan where you will go on your plant hunt. Getting started Have a good look around outside. Look up and down, in corners, on buildings and patches of land. Remember, clues about plants might be hidden anywhere! Can you find any plants with flowers? Where is the strangest place you can find a plant growing? Do you notice anything about where you find plants growing? How can you make sure that everyone stays safe? Test your ideas If you find any plants, can you work out how they got there? Share your ideas Take photographs or draw pictures of the plants you find to make a plant detective album. Mark on a map where you found the plants. Extra things to do Try to discover the names of the plants you found. Try to find out if plants always need soil to grow. Would you find different plants at different times of year?
