Solar Energy-Hurumanu

Solar Energy

Aim: To learn how solar energy is used.

Hypothesis:

These are the colors-What one attracts the most heat:

White-

Silver- 

Black-

-I think that black would attract the most heat because whenever i touch other colors on a hot day it feels normal but when i touch black it is hot and black also absorbs sunlight and makes it hot.

Materials:

1. Piece of white paper

2. Plastic cup x1

3. Heat lamp

4. Polystyrene cup x2

5. Tin foil

6. Black plastic

7. Thermometer

Steps:

1. Wrap the tin foil around the Polystyrene cup.

2. Plug in the heat lamp to a power point

3. Wrap the black plastic around the other cup 

4. Pour water inside all 3 of the cups and use white paper under neath the white cup and put the tin foil cup on tin foil and put the black cup on black plastic

5. Face the heat lamp towards the Cups

6. Wait 15 minutes and check how hot it gets with the thermometer

Findings:

I found out that black is the Hottest 

Time	Cup 1 White	Cup 2 Black	Cup 3 Tinfoil
0	16	16	16
15	21	24	21
30	21	23	21
45	22	23	22

Conclusion:

Activity:

In pairs rate the livability of coal vs solar energy.

Today we have been continuing learning about solar energy and the changes it does to humanity and earth.We made diagrams and written key words in our hurumanu books we had to connect the things that relate.

Comparing Coal energy with Solar energy ( Rate; 1 = poor to 10 = great)

Factor	Solar	Coal
Livability	8	4
Sustainability	10	1
Accessibility	7	7
Cost	4	1
