1. Differential Heating

Lecturer Procedure

Step(s) to Follow Expected Result

1. Start with the strip in contact with one of the lightbulbs.

2. Plug in the power cord to wall outlet

3. Use Bunsen flame to heat strip

The strip will bend toward the other lightbulb, eventually making contact and lighting it.

*Troubleshooting - If the strip doesn't bend toward the 2nd bulb when heated, turn strip around*
