CRESTStar Investigators is a UK-wide award scheme that enables children to solve science, technology, engineering, and maths (STEM) problems through practical investigation. The activities focus on a mixture of practical activities and discussion, and encourage children to work independently of adults. They are designed to be used primarily outside of lessons and you don't need a science background to run them, as full notes are provided as part of the resources. The activities are suitable for STEM clubs, the classroom, and home education. www.britishscienceassociation.org/creststar
