✧･ﾟ:Solar Energy

╔═══════════════ ∘◦ ☆ ◦∘ ═══════════════╗

Aim: To learn about how solar energy is used.

Hypothesis: I think that black will attract the most heat.

Materials:

1. Solar Heater
2.  Thermometer
3.  Tinfoil
4. White cup 
5. Clear Cup
6.  White Paper
7. Black Plastic 
8. Water

Steps

1.  Get your materials.
2. Set up your lamp.
3.  Cover the cups one cup in tin foil, and one cup in black plastic.
4.  Place the cup with tin foil on a tinfoil sheet, Place your clear cup with black plastic on to black plastic and finally put your white cup on a white piece of paper. 
5.   Put all the cups in a line.
6. Place them in front of the lamp.
7. Record every temperature every 15 mins.

Findings:

Time	Cup 1 White	Cup 2 Black	Cup 3 Tinfoil
0	16	16	16
15	19	21	21
30	20	22	20
45	20	24	21

In pairs rate the livability of coal vs solar energy.

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

Factor	Solar	Coal
Livability	10	4
Sustainability	10	2
Accessibility	10	3
Cost	9	5
Your choice...	10	1

Conclusion:

1. Solar power is more sustainable than coal is.

2. Sun, wind & water are all renewable energy.
3. The color black attracts the sun & heat.
