Which Is Hotter Color Science Experiment

In this fun and easy color science experiment, we’re going to investigate if certain colors get hotter faster than others.  

Materials:

• Two thermometers
• One sheet of white paper
• One sheet of black paper
• Two tin cans
• Black paint
• White paint
• Pitcher of water
  
  
  
  
  

Instructions:

1. Place each thermometer outside in the sun.
2. Put the white piece of paper over one of the thermometers and put the black piece of paper over the second thermometer.
3. Wait thirty minutes.
4. While you are waiting, paint one of the cans white and the other can black.
5. Once thirty minutes have passed, write down the temperatures from each thermometer.
6. Now fill each can with water.
7. Place a thermometer in each can and place the cans back outside.
8. Put the white piece of paper on the white can and the black piece of paper on the black can.
9. Wait thirty minutes and then write down the temperature from each thermometer.

How it Works:

The black color absorbs more sunlight. This converts to heat and increases the temperature. The white color reflects more sunlight and thus does not absorb as much heat. 

Make This A Science Project:

Try this experiment with different colors. Try spraying sun block on the black color. Try spraying sunblock on the surface of the water.
