EXPERIMENT 9:

HELPING YOUR REFRIGERATOR
WORK EFFICIENTLY

Two ways we all make our refrigerators work harder (and thus use more energy) are:

1. Putting warm (often steaming) things in the refrigerator

2.Opening the refrigerator door more times than absolutely necessary

This simple experiment will show you how significant these everyday “mistakes” are. Before you begin, though, be sure to get permission. And pay close attention to the instructions — if you are careless you could spoil some food.
