2. How does the color of a building affect the indoor temperature?

Purpose
Can Your House's Color Reduce Your Summer Energy Bill?

4. Research
If you are going to cut the grass in the summer, you wouldn’t wear a black shirt. You would get too hot.
“A black object absorbs all wavelengths of light and converts them into heat, so the object gets warm.”
“…white, on the other hand, reflect all wavelengths of light and therefore absorb the least heat.”
The more pigment an object has the more it will absorb light energy.

5. Hypothesis & Variables
If I paint a house black, then the indoor temperature will be greater than a house painted white. Independent Variable – Color of house Dependent Variable – Temperature Controlled Variables – house size and materials, placement of houses, time outside, thermometer

6. Materials I Used
2 sheets each of Black, white and purple construction paper
One pair of Scissors
Three cereal boxes 20.5oz size
Transparent Tape
3 Thermometers
A sunny spot outside on a day that
was 70 degrees Fahrenheit

7. Procedures
Cover one cereal box with 3 sheets of black construction paper using transparent tape.
Cover one cereal box with 3 sheets of white construction paper using transparent tape.
Cover one cereal box with 3 sheets of purple construction paper using transparent tape.
Put a thermometer in each box, close it, and take it outside.
Place the boxes in the sunny spot you picked. Leave it there for 30 minutes.
After 30 minutes, open the box and quickly read and record the temperature on the thermometer.
Put the thermometer in the shade somewhere near the box (still outside). After it has adjusted to the shade, read and record the temperature.
Repeat steps 4-7 two more times for each colored box on two different days.

10. Results – 1st Trial

11. Results – 2nd Trial

12. Results – 3rd Trial

13. Results - Average 82 75

14. Graph Variation

15. Conclusion
The white box was the coolest inside, compared with the temperature in the shade nearby. The black box absorbed the most light, and this energy was transferred inside of the box over time and warmed up the thermometer. The black box was the hottest compared with the temperature in the shade. The purple box absorbed some light, so it also warmed up, but its temperature was somewhere in between those of the black and white boxes.
My hypothesis was if I paint a house black, then the indoor temperature will be greater than a house painted white. My results do support my hypothesis.
If I had to do this experiment again I would pick different colors to test or test indoor temperature depending on house shape.
