  1. Do different colors absorb different amounts of heat?

  2. Purpose Which color absorbs the most heat?

  3. Hypothesis I think the dark blue cup will absorb the most heat.

  4. Materials For this project I used: • Six different color cups • 45 watt flood lamp • Digital Thermometer • Measuring cup • 150ml water per cup

  5. Procedure • Step 1: Gather the materials that you will need for this experiment. • Step 2: Fill each cup with 150ml of water • Step 3: Place all cups under the lamp so all the cups will receive the same amount of heat. • Step 4: Measure the starting temperature. • Step 5: turn on the lamp and wait 90 minutes.

  6. Step 6: Measure the temperature of each cup • Step 7: Record your results • Step 8: Repeat steps 2-7 two more times to make sure your results are accurate. • Step 9: Calculate the average temperature for each cup.

  7. Variables Manipulated: The color of the cup Responding: The temperature each cup reaches Controlled: Amount of water, time under the lamp, placement of cups (so each cup receives equal amounts of heat)

  8. Results Starting Temperature: 6.6° C

  9. Analysis

  10. Conclusion The color that absorbed the most heat was the blue with an average temp. of 22.3°C . The color that absorbed the least amount of heat was the white, with an average temp. of 18.9° C. My hypothesis was correct.

  11. Sources of Error Three sources of error would be: • The starting temperature may have been slightly different for each cup. • The cups may not of received the same amount of heat. • The amounts of water may not have been equal.

  12. Ways to Improve Three ways to improve are: • Make sure all starting temperatures are the same. • Use a bigger lamp so all the cups receive equal amounts of heat. • Find a more accurate way to measure the water.
