1. Make an air leak indicator by cutting a piece of tissue paper 5 inches wide and about half the length of a pencil. Tape the long side of the tissue paper to a pencil. Facial tissues may be used instead of tissue paper.

2. Become familiar with how incandescent and compact fluorescent light bulbs work by exploring the following sites:

3. Purchase incandescent and compact fluorescent light bulbs with the same number of lumens (equivalent light levels). The Incandescent vs. Compact Fluorescent overhead transparency has a comparison chart, but the number of lumens may vary with brand, so be sure to check the packaging or display for this information. Gather desk and/or table lamps for the student investigation. Each group needs two light sockets. Make sure the bulbs you purchase are rated for the sockets you’ll be using.
