4. Place 1 cup full of tap water with no cup over it on a piece of tinfoil 
5. Get a heat lamp 
6. Leave it for a little bit 

Which surface conducts/attracts the most heat?

Time + temperature	Cup 1 White paper	Cup 2 White paper+ plastic.	Cup 3 purple paper	Cup 4 Tinfoil
0	12'c	12'c	12'c	12'c
45 minutes	16'c	14'c	22'c	24'c
65 minutes	20'c	19'c	20'c	20'c
75 minutes	18'c	19'c	22'c	26'c

Findings:

Conclusion: For our experiment, we had 4 different cups on a table with a heat lamp on it. The first cup was plain water on white paper the first time we tested it was 12'c then after lunch which was 45 minutes then we waited 65 minutes the 75 minutes so we could see the different heat each time
