Steps

1.   Get your Materials.
2.   Put water in the 4 cups.
3.  Put each cup on a piece of white paper, black paper, tin foil and a bigger cup over top of the smaller cup over a white piece of paper.
4.  Take each cups temperature with a thermometer.
5.  Use a heat lamp to heat the water.
6.  Wait 40 minutes before checking the temperature again.
7. Turn off the heat lamp.
8. Check the temperature again then wait 15 minutes.
9. Check the temperature again the wait another 15 minutes.
10. Check the temperature and your finished.

Which surface conducts / attracts the most heat?

Time + temperature	Cup 1 White paper	Cup 2 White paper + plastic.	Cup 3 Black paper	Cup 4 Tinfoil
0	8	8	8	8
40 minutes	12	11	22	20
55 minutes	13	13	20	19
70 minutes	14	14	19	16

Findings:

Before we started all of the cups were at 8 degrees. Then we went out for luch which was 40 minutes then we checked them and the were at 12, 11, 22 and 20 degrees. We waited 15 minutes and it was at 13, 13, 20 and 19 degrees. Then we waited another 15 minutes and each cups was at 14, 14, 19 and 16 degrees

Conclusion

During the process one of our cups fell over so that was unfortunate but there was still water left that we used for our findings.
