In this optics activity, learners examine how a transparent material such as glass or water can actually reflect light better than any mirror.

Can gelatin (like Jell-O ®) change the speed of light?

In this activity, learners test the Law of Reflection based on experimental evidence. Learners produce raw data and explanations based on their data: pencil tracings of incident and reflection rays.

In this activity, learners use gelatin as a lens to investigate the properties of laser light.

In this activity, learners use a laser pointer, empty soda bottle, rubber plug and water to demonstrate total internal reflection.
