I need to know materials I need( Example ) clay, thermometer
clay would work, something like plastacine or play doh, pastry would also work wellYou'll need about 3 equal size peices of whatever material you choose to useOne you can leave in the open as a control substance Three that you could wrap in different thingsLike, brown paper, cling film and tin foilRemember to leave them all in the same place for the same length of timesomaterial to cool, three sheets of different material, a thermometer (maybe one to take air temp too) and a table of some sort to record your results at several different times.
