The addition of light bulbs and fluorescent bulbs is a great idea to tap into what the students already knows a little about and then build from there. I will add this to my classroom also. Since I also teach physics, I do more with light at that level as far as how our eye sees color and light, colors from addition and colors from subrtraction.

We found out this year that our students could not understand light at all. We had a pre-questionnaire in which we asked them about radiowaves, how their eyes perceived light, colors, etc. Once we had them fill out the questionnaire we talked about light and straightened out their many misconceptions. Then we edited our old flame lab to include examples of lightbulbs and fluorescent bulbs and even looked at some spectral images of different stars and the absorption and emission lines. It made them get the lab much better.
