Hurumanu- Solar energy

Solar Energy

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

Hypothesis:

I think that what will happen with solar energy's or what will happen with one...

Hypothesis meaning... It means to guess something... but out of the information you already have...

I think that the black covered cup will heat up the most because of how the heat will or can get threw the black paper but also make the heat stay inside of the surrounding black paper... 

Materials:

1.  Three plastic cups
2.  Tinfoil
3.  Black paper
4.  white paper
5. Water 
6. Heat lamp

Steps

1. Get the materials.
2.  Set up the cups.
3.  Cover the clear cup with a cut black plastic bag.
4.  Put the cup with a black plastic bag on top of another black plastic bag.
5.   Put the tinfoil cup on top of the paper.
6. Put the white cup on top of the paper.
7. Measure it every minute.

Findings:

Time	Cup 1 White	Cup 2 Black	Cup 3 Tinfoil
0	16 degrees	16 degrees	16 degrees
15	18D	19D	17D
30	21d	26d	23D
45	23d	24.5	25d

In this photo, there is a heat lamp heating up our 3 cups

Conclusion

THE BLACK CUP HEATED FASTER THAN ALL THE OTHERS BECAUSE IT WAS IN THE MIDDLE AND THE HEAT LAMP WAS AIMING AT THE BLACK CUP. THE WHITE CUP WAS TIED WITH THE TIN FOIL AT SAME DEGREES IN 30 MINUTES. I LEARNT THAT HEAT LAMPS CAN GET VERY HOT IN SHORT AMOUNTS OF TIME.

Activity:

In pairs rate the livability of coal vs solar energy.
