Color Vs Energy

By Lynn.  RM19

Question:  

Will a dark or light color paint on your house reduce your energy bill?

Hypothesis:

I think dark colors take more energy to heat because they don't attract as much light as the bright colors,therefore I think a light color will be better on your energy bill.

Variables:

Manipulated-

*paint color

Controlled-

*time of heat

Responding -

*amount of time heat stayed in house

materials:

2 shoe boxes, 2 thermometers ,1 heat lamp ,1 Large tray ,1 of each orange and dark blue Paint, Paintbrushes

Procedures:

Gather materials Paint two different boxes one a dark blue and one orange.Put boxes under heat lamp then turn on heat lamp.Put thermometers in the boxes.Wait for about 5 mins then check the temperature.Record temperature then do steps 5-6 again. See if your answer is right.

Conclusion:

My hypothesis was right because the darker the house the hotter it is inside. The lighter the color of the outside of your house,the cooler it will be inside . If your house was black, it would be hotter than a house painted white.

Research:

*The reason why your energy bill is so high is when your house is a dark color it  more energy to make it brighter.


*The reason why your energy bill goes down when you paint your house a bright color and the sun touches the paint it makes the room brighter.
