Heat Absorption Lab
Does the color of the object affect heat absorption?
If the color of an object affects how much heat it absorbs, then the darker the color, the hotter the temperature is going to be. The darker colors of an object absorb more heat than lighter colors that reflect heat.
Independent Variable: Color of paper
Dependent Variable: Temperature
Control Group: The starting temperature of the paper is the control group because it is used to compare how much the temperature has risen from the beginning of the experiment. It is not added to the average.
Constants: Size of paper, duration in sunlight, and distance from heat source: the sun.
1. Gather materials:
a. Paper: white, red, blue, and black construction paper
c. scotch tape
2. Measure construction paper to the size 5”x 8”
3. Cut paper to that size
4. Now fold each paper in half.
5. Tape the two sides of the paper connected to the fold to create a small pocket.
6. Place thermometer tip inside each of the open pocket – take base line temperature in degrees Celsius. Records results.
7. Place all 4 pockets in direct sunlight and time exposure using stopwatch for 30 minutes then check temperature. Records results in degrees Celsius.
8. Repeat step 7 an additional two times and record results.
Color of Paper Control Group:
Starting Temperature Temperature (in Degrees Celsius) Average
Trial 1 Trial 2 Trial 3
White 22° 25.4° 39° 40° 34.8°
Red 22.5° 31.6° 41.7° 43.2° 38.8°
Blue 23.2° 40.3° 43.2° 45.4° 43°
Black 24.5° 42.3° 47.6° 50.3° 46.7°
Heat Absorption Levels of Colored Paper Measured in 30 Minutes trials
Average temperatures of the papers that absorbed heat
My hypothesis was correct because the darker colors of the paper absorbed more heat than the lighter colors. Therefore, the color of an object does affect how...
