Amateurs of alternative energy build a mini parabolic-trough solar energy collector and use it to heat water. Temperature is recorded over a three-minute period and the data is graphed and analyzed. Note that in order to paint aquarium tubing black, you will need paint designed to adhere to plastics.

Pros

• Demonstrates the effectiveness of solar energy as a renewable energy source for heating water
• A concisely written lab activity that comes complete with background and follow-up questions

Cons

• Controlling water flow may be quite a challenge, so be prepared to have lab groups repeat the process as they become more familiar with their constructed equipment
