Solar Energy

Aim: To find out which colour attracts the sun's heat.

Hypothesis: I think that it the colour Silver or black with attract more sunlight than the colour white. 

Materials:

1.  Tin foil Plastic Cup
2.  Clear plastic Cup
3.  Black plastic paper
4.  White A4 Paper
5.  A4 sized foil 
6. Thermometer
7. Heat lamp
8. Plug for Heat lamp

 Steps

1.   Get your materials, set them up like the photo below.
2.  Plug in the heat lamp and place it facing in towards the cups.
3.  After 15 minutes measure each cup with a thermometer and record findings.
4.  After 30 minutes measure each cup with a thermometer and record findings.
5.  After 45 minutes measure each cup with a thermometer and find recordings.
6. 
   

Findings: Below is a photo of how we setup our experiment and also how it should look like, so on the left side we have our heat lamp set up in the middle, we didn't put the heat lamp close up to the cups as you can see in the photo. 

Time	Cup 1 White	Cup 2 Black	Cup 3 Tinfoil
0	16	16	16
15	19.1	19	20
30	25	27	26
45	20	24.5	22.5

Conclusion:

Today in science we have started on a new experiment called Solar energy. I was in a group of four with Janel, Anneleise, and Rowina. We have to collect all of the materials that was needed for the experiment and had to record the temperatures of each of the cups. A tin foil cup, a white cup and a clear plastic cup covered with the black plastic. Overall it was a great experiment and lesson learning about solar  energy.
