Inquiry | Testing experiments

Insulators are used to stop heat from moving place to place. Five materials were tested for the ability to insulate: glass,plastic,metal,paper, and polystyrene.

The best thing for keeping things warm was polystyrene because the average cooling rate was 8.

 The worst things for keeping things cold were: plastic,paper,tin.

The best insulators for keeping things warm and cool was tin because the cooling sheet for tin was 13 and the warm sheet was 10.
