Solar energy

Aim - is to see how Solar Energy works.


Materials:

1. Cups (x4) 

2. Water 

3. 1 large cup

4. 2 sheets white paper

5. 1 large black piece 

6. Thermometer 

7. Tinfoil 

8. Lamp

Steps
1. Fill the cups with water 

2. Then you place each cup on separate pieces of sheets and put the large cup on on of the cups that are on a white piece of paper.
 

3.  Then plug your lamp in and make sure that it is covering all cups.Then you leave it for the amount of time it requires.

4. When that's done then grab the thermometer and see how hot it is.

5. Then you put it done on your blog. 

Which surface conducts / attracts the most heat?

The tinfoil and black paper had the most heat in 40 minutes which was both 20 degrees

Time +

temperature
Cup 1
- 0 minutes 12 degrees 40 minutes 15 degrees 

White paper

Cup 2
White paper+ plastic.
- 0 minutes 12 degrees 40 minutes 14 degrees 

Cup 3
Black paper
- 0 minutes 12 degrees 40 minutes 20 degrees 

Cup 4
Tinfoil
- 0 minutes 12 degrees 40 minutes 20 degrees

Findings:

That the tinfoil and black paper were the hottest ones at 20 degrees in 40 minutes which kind of warm. But the least warmest was actually the plastic and white paper one which only reached 12 degrees in 40 minutes which only went up 2 degrees since we started it.

Conclusion: 

I think that they are the hottest because black attracts the sun to it and we used black paper.But I think that tinfoil was high because it is like a mirror which reflects the sun which would’ve reflected it into the water in the  cup.
