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	15	13	12	13
40 minutes	17	16	24	22
-15 minutes	18	17	23	22
-30 minutes	17	18	22	22

Findings:

That findings that I have is that some cups temperature went up after the heat lamps were taken away. I think that it did that is because the room was closed in and we were talking and it heated the temperature. 

Conclusion:

My conclusion is that some water heat was different than others. Because of the material that some were on. Also the room that our cups were in was closed off. Also we were in the room so the heat of our breath had an affect on the temperatures. So I do not know if this is a precise recording.
