How does changing the color of an aluminum affect the
rate of temperature increase of water inside the can?

Procedure
• Paint six different cans in different colors
• Fill the cans with tap water
• Place one thermometer in each can
• Place the cans in direct sunlight
• Record the initial temperature of the water
• Record temperatures in two minute intervals for 20 minutes
• Repeat for three trials

Conclusion & Evaluation
• The brighter the color of can is, the greater intensity reflected upon the aluminum cans.
• Intensity Reflected.
• By changing the color of the aluminum can, the average temperature rate decreases.
