Aim: To learn about how solar energy is used.
Hypothesis -
I think that black would attract the most heat rather than white or silver.
Materials -
- White cup x 2
- Clear cup
- Black plastic
- Tinfoil
- Paper
- Water
- Thermometer
- Heat lamp
- Grab all of your equipment from your teacher.
- Keep one of the white cups on the side because that will be your white color for this experiment.
- Mold some tinfoil onto the other while cup to create your silver cup.
- Cut along the top of your plastic bag so both ends are open and fit around your clear cup.
- Pour some water in each cup making sure it is around 1/4 full.
- Turn on your heat lamp making it face all of the cups so the experiment has the correct results.
- Test your water in each cup every 15 minutes for about 45 minutes making sure to leave the thermometer out long enough to get the right temperature in each cup.
