Students will conduct an experiment focusing on materials and their properties, going on to create a campaign for change in their school or community. Includes fact file to support teaching, image reel, activities, and links to follow-up learning. Linked to national curriculum in England, Curriculum for Excellence in Scotland, Curriculum for Wales, and Eco-Schools topics.
