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.

Plant parents Activity

Plant parents Activity Card Uncle Astro has a broccoflower in the fridge - it’s a mix between broccoli and cauliflower! Uncle Astro “It is a GMO - a genetically modified organism.” Stella Cosmic “GMO foods come from plants that have had some genes edited to change the traits of the plant. Normally farmers use selective breeding to make fruits and vegetables that are bigger, tastier, or more resilient against pests. Sometimes scientists use gene editing to make the crops better adapted for droughts or flood prone areas or resilient against pests. Selective breeding takes longer, but genetic modification is much more difficult.” “Wow, think of all the different foods you could make!” Your challenge What ‘new’ crop would you make? Could you make it through selective breeding or would it need to be genetically modified? What would the benefits of your new crop be? Consider improving taste, appearance or health benefits. Discuss What traits would your ‘new’ crop have from the plants it was made from? What do you think the positives and negatives are of genetically modifying plants? Can you think of concerns that people might have? How could changing a plants’ genes help people around the world?

Getting started Think about some crops you would like to combine. Do research about the plants they grow on. What traits would you take from each plant? What will you call your new crop? Test your ideas Are your two plants similar enough to use selective breeding? Or would you need to use genetic modification? Share your ideas Design a poster to encourage people to buy your new crop.
