The Fun Tests activity includes two tests that students can do at home.

• The first test measures the water flow of their showerhead. If the shower fills a half-gallon milk carton in less than 10 seconds, it is using more water than an energy-efficient shower head would use.
• The second test has students search for air leaks around doors, windows, and air conditioners and notify an adult of any leaks they find. This activity can be done at home or at school.
