Solar Energy

Aim: To find out which colour attracts the suns heat.

Hypothesis: I think the colour black attracts the sun because it absorbs everything coming in from the sun and it is the darkest colour.

Materials:

1.  A plastic cup
2.  A clear plastic cup
3.  A piece of white A4 paper
4.  A piece of tinfoil
5.  A plastic cup covered in tinfoil
6. A square piece of a cut up black plastic bag
7. A black paper sleave
8. A  small heat lamp
9. A themomator

Steps

1.   Get a plastic cup and the A4 paper and place the cup onto the paper on a hard surface
2.   Next to the A4 paper Get a plastic cup and put the black paper sleave over top and place the cup onto the square piece of the cut up black plastic bag
3.  After that next to the black sleave cup Get a piece of tinfoil and the plastic cup covered in tinfoil place the tinfoil cup onto the piece of tinfoil.
4. Then get the small heat lamp and plug it into a plug on the wall and place it in front of all of the cups so the get heat in them.
5. In 15 minutes put the themomator in each cup at then put down your recordings
6. After that take out the themomator for 1 minute
7. Next do the same thing for 30min and 45min

Findings:

I these photos from the experiment called solar energy it shows you how to set it up and what the experiment is.  

Time	Cup 1 White	Cup 2 Black	Cup 3 Tinfoil
0	16c	16c	16c
15	20c	25c	19c
30	20c	35c	20c
45	20c	30c	20c

Conclusion : Today in science we have been doing an experiment about solar power we need to use a thermometer to record the water in the cups and then wait till it is done. we had to all of the materials from the teacher so we can set it up and get ready for the experiment. Black attracts more than silver and white because a black object absorbs all wavelengths of light and converts them into heat so the object gets warm.
