Catching the sun movie

Materials:

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

Steps

1. Fill 3 of the cups up with water.  
2. Lay down each of the surfaces.
3. Place the cups of water onto the papers and tinfoil. For one of the white paper place a the bigger cup on the top of the smaller one.
4. Plug in the heat lamp and wait for each time stamp.  
5. After waiting for each time stamp check the temperature and right down the results.  

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	12	12	12
40 minutes	15	14	20	20
15 minutes	15	13	19	19
30 minutes	17	19	22	22

Findings: During this experiment I found that when we didn't have the heat lamp on the temperatures still went up which I didn't expect to happen, we were in front of natural light so that could have somehow triggered the temperature to rise with out the heat lamp. Also the black paper and tin foil had the same results which but the two white paper didn't 

Conclusion: I thought this experiment was very interesting, it was cool to see how different objects/things can effect the temperature of something. In the end I was really surprised how two cups of waters temperature rise without the heat lamp. Overall I enjoyed this experiment and would love to do something similar to this one again.
