This experiment is about keeping the house cool in summer.
"The sun can't heat up your house if it can't get in." That's true in summer as well as winter. Awnings, louvers or shutters stop the sun before it gets into the house.
Shades, curtains or blinds work to help a room stay cool too, by reflecting some of the heat back out. But not so well as something like and awning that keeps the sun from getting in the first place.
- Make the awning and attach it to the house with push-pins.
- Place house with the large windows facing the sun. Try to do this on a day when the Energy House will get the same amount of sun as in Experiment 10.
- Measure and graph the heat rise.
- Graph the temperatures.
Things to Notice:
Compare your graph to Experiment 10 -- does the awning really work to keep the house cool? People use electricity to run air conditioners to take away the heat after the sun has heated up their house. Do you think it would be better and cheaper to prevent the house from heating up in the first place?
