Science Fair Projects on Effects of Color on Temperature Abstract asked the question, “How does shingle color affect temperature inside the house?”
4th Grade – Age 9
PROBLEM: – What effect does shingle color have on the temperature inside a house?
HYPOTHESIS: – I believe houses with dark colored shingles will be hotter inside than houses with light colored shingles.
I put together the 5 cardboard boxes and hung a thermometer in the middle of each box. Next, I covered the top of the first box with one layer of fiberglass asphalt roofing shingles. I covered the 2nd, 3rd, and 4th box in the same way, but I used different colored shingles. I left one box uncovered – no shingles. I set all 5 boxes in a sunny spot in my cul-de-sac. All the boxes were sitting on the same surface and facing the same direction. I recorded the outside temperature and the temperature inside each box every hour from 7:00am until 7:00pm.
Dark colored shingles will make the temperature inside your house hotter if it is sunny because they absorb light/heat from the sun. If you have light colored shingles or paint your house white on top, your house will stay cooler when it is sunny because light colors reflect light/heat from the sun. If it is not sunny, shingle color doesn’t effect the inside temperature of your house. Fiberglass asphalt shingles do not help to keep heat in or out of the house. They are not insulative.
If I did this experiment again, I would use shingles made out of different materials.
