Designing a lunchbox to keep food cool

A graphic organiser for children to plan their design for a lunchbox that keeps food cool. Space to make notes or write reasons as well as areas to sketch the inside of the lunchbox and also provide a diagram of how the insulation works. Storage could be how the lunchbox will be stored - thinking about the shape of the lunchbox. Pupils could also consider the eco friendliness of the materials used.
