Do Colours Attract Heat?
Aim:
To paint coke cans different colors and test which colours attract the most heat.
Research:
After researching colours on the internet, I found that darker colours, like black or purple, should attract more heat than lighter colours such as pink or yellow.
Hypothesis:
I predict that the darker colors, will attract more heat than the lighter colours because they will absorb the heat, instead of reflecting it.
Equipment / Materials:
I will need the following:
• 7 coke cans.
• 7 different coloured spray paints.
• A paintbrush.
• Water
• A thermometer.
• Pen and Paper to record results.
Method:
These are the steps I took in my experiment:
1. Find 7 coke cans with the same shape and volume.
2. Apply 2 coats of white oil paint.
3. Paint 6 of the cans different colours leaving the seventh white.
4. Fill the cans with water. And leave in a shaded place for 20 minutes.
5. Check temperature of water in each can. (Should be the same.)
6. Place all 7 cans in a row in a hot sunny spot.
7. Return in an hour and check the temperature of each can, record each temperature.
8. Return another hour later and repeat step 7.
9. Return 2 hours later and repeat step 7.
10. Find the increase in temperature for each can.
11. Empty each can and recycle them.
