Interactive introduction to the 17 Sustainability Development Goals, adapted from free ‘Earth Cubs’ resources. http://earthcubs.com/ Slides could be printed double-sided, laminated for outdoor use & longevity, and weighted down with props eg, small book for education, plastic bottle of water for water, empty food carton for food, etc. Hanging them in a random order along a trail (from trees or along corridors) makes the trail more stimulating. QR code reader will unlock short videos. The trail sheet can be used as pattern/number recognition exercise for v young pupils, or increase the challenge by linking each image to its descriptor, ‘what can I do?’. Alternatively encourage older pupils to set up the trail for younger children - ‘which props would you choose for each card?’ 'would you embed different video clips?'etc Easily developed further for staff CPD about SDG’s, or for pupils to do with parents.
