• «────── « ⋅ʚ♡ɞ⋅ » ──────»
• Aim: To learn about how solar energy is used.

Hypothesis:

I think that the colour black would attract the heat the most. 

Materials:

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

Steps

1.   Gather your materials.
2. Set up your lamp.
3.  Cover one of your cups with tinfoil.
4.  Place the cup with tinfoil on a sheet of tinfoil.
5.  Get your clear cup and put black plastic over the sides.
6.   Place cup with black plastic on a sheet of black plastic.
7. Get a white cup and place it on a sheet of white paper.
8. Put the cups in a line close together.
9. Place light in front of the cups.
10. Every 15 minutes use your thermometer to record the data of all three of the cups.

Findings:

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

Activity:

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	2

Conclusion:

1. Solar power is more sustainable than coal is.
2. Sun, wind & water are all renewable energy.
3. The colour black attracts sun & heat.
