Introduction I chose this topic because I am interested in buying a pair of socks that will keep my feet warm in the winter. I am also curious about which materials make the best insulators.

Aim Which fabric makes the best insulator?

Hypothesis I think that wool will be the best insulator becasue it is anatural fibre and we often wear woollen jerseys in cold weather. I think that nylon will be the worst insulator becasue it is a man-made fibre and it is very flimsy.

Equipment 1 nylon sock 1 woolly sock 1 cotton sock 1 polar fleece sock 4 x 200ml beakers 4 x thermometers stopwatch

Notes to self • See mr Marsh about borrowing beakers and thermometers
 * ask dad for some of his smelly rugby socks
