Show video, "Light & Optics" by Bill Nye. More than adequate coverage of/preparation for SOLs. Fast-forward to ~24:00 [begin misc. notes from video] Use a 35mm slide projector (e.g., a TMC projector or old filmstrip projector) to project a beam of light into an aquarium of colored water; point beam of light at a mirror. It's cool -- you can see the path of the light beam clearly! Use the same set-up for a follow-on demo of "internal reflection": When the mirror (immersed in the water) is angled sharply enough, there is a point at which the beam of light is reflected off the upper surface of the water in the aquarium. Remote controls (e.g., for TVs, VCRs, etc.) use infrared light. Point the remote control at both a piece of white and black paper: the beam will reflect off the white paper; be absorbed by the black paper. Remember angle of incidence = angle of reflection. Concave vs. convex. Refraction of light in water: Aim low to touch objects in water.
