Which color absorbs the most heat?Which color absorbs the most heat?

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

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

• 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.

• 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.

Manipulated: The color of the cupResponding: The temperature each cup

reachesControlled: Amount of water, time under the

lamp, placement of cups (so each cup receives equal amounts of heat)

Cup Color Time 1 Time 2 Time 3 Average

Blue 21.8°C 22.9°C 22.2°C 22.3° C

White 19.0°C 18.6°C 19.2°C 18.9°C

Orange 19.7°C 20.8° C 20.1°C 20.1° C

Yellow 19.3°C 19.4°C 19.7°C 19.4°C

Red 20.9°C 21.8°C 21.2°C 21.3°C

Green 19.7°C 21.7°C 21.1°C 20.8°C

Starting Temperature: 6.6° C

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.

Three sources of error would be:Three sources of error would be:1.1. The starting temperature may have been The starting temperature may have been

slightly different for each cup.slightly different for each cup.2.2. The cups may not of received the same The cups may not of received the same

amount of heat.amount of heat.3.3. The amounts of water may not have The amounts of water may not have

been equal.been equal.

Three ways to improve are:1. Make sure all starting temperatures are

the same.2. Use a bigger lamp so all the cups receive

equal amounts of heat.3. Find a more accurate way to measure

the water.
