Solar Energy

Aim: To learn about how solar energy is used. 

Hypothesis: I think that silver will attract the most heat because, when the light shines on silver it will reflect on it. 

Materials:

1. White Paper 
2.  Styrofoam Cup (X2)
3.  Clear Cup
4. Roll of Tinfoil 
5. Black plastic
6. Lamp
7. Thermometer

Steps

1. Gather all materials.  
2.  Put down some paper, tin foil and a piece of black plastic on the table.
3.  Wrap some tin foil on one styrofoam cup. 
4.  Cut a circle piece of black plastic and wrap around a clear cup.
5.   Put each cup on eat coloured material. etc. Black, white and silver.
6. Set down lamp and face towards cups. Make sure lamp is on.
7. Wait every 15 minutes and use thermometers to record the temperature. 

Findings:

Time	Cup 1 White	Cup 2 Black	Cup 3 Tinfoil
0	16	16	16
15	20	23	20
30	21	23	21
45	21	23	22

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	1	9
Your Choice...	Yes	No

Conclusion:

1. Solar is a renewable source because the sun can live up to millions of years. 
2. The sun has enough energy to power earth.
3. Water is renewable energy, because of the water cycle, it repeats all over and over again. 
4. The wind is a renewable energy because it does run out.
5. It costs more to my coal rather than solar power. 
6. Solar is better than coal because solar can live up to billions of years.
