1 Conduction of heat

2 heat moves from hot to cold
what happens to the drinks?

3 name some good insulators

4 name some good heat insulators
duvets (feathers) cotton wool name some good heat insulators polystyrene bubble wrap sheep's wool fleece

5 a Mexican wave particles DO NOT MOVE, but they VIBRATE

6 Testing different metals
Material Time 1(s) Time 2 (s) Time 3 (s) Ave time (s) Copper Aluminium Brass Steel glass

7

8

9 Different properties for different jobs

10 Explain why coffee cups are made of polystyrene
why double glazing is best why two thin layers are better than one thicker jumper why a plastic seat is warmer than a metal one why ice melts quicker on metal than plastic even though plastic is warmer
