Solar Energy (Part 2) | Conservation/Sustainability

Welcome to another post on my blog. For science today, we have been writing instructional writing for our Solar Energy experiment. Here is my work. I hope you like it.

Title	Solar Energy
Aim	To find out which colour attracts the suns heat.
Hypothesis	I think that white will attract the most because solar panels have white around the edges.
Materials	Heat Lamp 2 Styrofoam Cups Plastic Cup 2 Tin Foil Thermometer White Paper 100mls Water (in each cup) 2 Black Plastic Timer
Steps	Get a heat lamp, 2 styrofoam cups, a plastic cup, 2 tin foil, a thermometer, a white paper, 100mls of water (in each cup), 2 black plastic and a timer. Put the cups in order. (left, styrofoam cup, centre, plastic cup with black plastic, right, styrofoam cup with tinfoil through. Plug the heat lamp. Put some water in the cups. Every 15 minutes, check the temperature with a thermometer.  Record the findings.
Data/Findings	Time  Cup 1 White Cup 2 Black Cup 3 Tinfoil 0 16 16 16 15 17 17 17 30 17 22 18 45 18 22 18 When we timed the first cup (white) at fifteen minutes, only 1 degree had increased, which is pretty normal. At 30 minutes, we tested again and we got the same result, 17 degrees, there was no change in the cup. After 15 more minutes (45 minutes), 1 degree had increased, which led up to 18 degrees. The water had changed by 2 degrees, from 16 to 18. The second cup was similar to the first cup, but a bit different after. At fifteen minutes, it was 17 degrees. At 30 minutes, the temperature burst like a rocket and let up to 22 degrees Celcius. After 15 minutes, the temperature stayed at the same position, 22 degrees. The third cup with tinfoil, at 15 minutes it was 17 degrees like the white and black cup. At 30 minutes, it increased by 1 degree to 18 degrees. At 45 minutes it stayed the same.
Conclusion	In conclusion, my findings in this experiment state that black attracts most to heat. At 30 minutes, it went up to 22 degrees, which was surprising, because I thought that white had attracted the most when white got only 17 degrees. I had learnt that black attracts most to the sun’s heat. I think that darker colours attract more to the sun’s heat. That’s why the solar panels colour is black, not white. What I also leant today is that in hot countries, they paint the houses white because it doesn’t attract the sun. If they painted the house black, then, the house will be hot as fire.
