Melting Ice - Blocks

On the 25 of September  we did an experiment about trying not to let your ice blocks melt in the sun for 1 in a half hour.My group was Charlize & Poet. Our plan was to get some material, cardboard, polystyrene foam, cardboard holder, ruler, lunch bags, juicies and sellotape. When our juicies were in the sun for 1 and a ½ hours it started to melt.That's maybe why it was cold in our creation. I think our creation didn’t work because we put too many layers on.
