Materials:

1. Cups (x4) 
2.  Water
3.  Tin Foil
4.  2 sheets of white paper
5.  1 sheet black paper
6. Thermometer
7. 1 large cup
8. 1 heat lamp

Steps

1.   The first thing you need to do is gather all the material that you need.
2.   Fill up the cup with water in the right amount, they need to be the same amount.
3.  Place 2 white paper, black paper, and a tin foil on the table or on a hard surface.
4.  Put the cup in the top of the paper and the tin foil. 
5. Place the heat lamp in the front of the cup.  
6. The temperature should be different. 

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	12oC	12oC	12oC	12oC
40 minutes	15oC	16oC	26oC	25oC
15 minutes after, without the heat lamp	18oC	18oC	240C	23oC
15 minutes again but without the heat lamp	16oC	160C	22oC	22oC

Findings: We found out that if you place a cup in the top of the black paper it absorbed more heat than the one with the tin foil in the bottom. The heat of the white paper was almost the same as the white paper with plastic. 

Conclusion:

The black paper and Tinfoil has almost the same temperature. But the temperature of the white paper is the same as the white and plastic paper.
