Two things that came to my mind when I thought about light were:
1) Photosynthesis
2) The concept of the Speed of Light
Other groups and group members came up with:
Travels as a particle
part of electromagnetic spectrum
Travels in a vacuum
We also described different light sources that we saw. The glow stick produced a light green color that was easy to look at, while some of the other light sources were extremely bright and strained the eyes (LED, Fluorescent Lamp). Also we shined the lights on different CD surfaces to see what type of spectrum appeared. Some videos and pictures of that experiment can be seen below.
Finally, I especially liked learning about the chemistry behind the Glow Stick. The source of the glow comes from a chemical reaction between H2O2, and a oxalate ester. Depending on which color is desired different dyes are added.
