3.  Tin foil
4.  2 sheets of white paper
5.  1 sheet of black paper
6. Thermometer
7. 1 large cup
8. 1 heat lamp

Steps

4.   after checking the temperature scale it on your device
5. then write a conclusion

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	12'c	12'c	12'c	12'c
45 minutes	16	14	22	24
60 minutes	20	19	20	20
75 minutes	18	19	22	26

Conclusion

At the start the water was 12'c  and then the water started rising as you can see on the tally. My group and I all think that the reason why the water temperature rise went high was because we were sitting next to a window and also because we were sitting right under a light.
