A global primary Upd8 from ASE and Practical Action
This Upd8 looks at a 'big question' facing a girl called Grace who lives in Sudan...how can her family keep their fruit and vegetables fresh for longer?
Pupils gain an understanding of what it might be like to be a child like Grace, to live in a village with no electricity to keep fruit and vegetables cooll. They then go on to investigate how building a special container using insulation to stop heat transfer may help. Finally they look at the actual solution used by families like Grace's in Sudan.
