Not only does a concave mirror focus light waves, it can also concentrate infrared radiation into a hot spot. If you have a small electric heater and such a mirror, demonstrate this for your physical science class.

Concave mirrors and the images they produce are traditional topics in the physics classroom. This resource explains how to set up an investigation of them, and it provides you with the explanation of concepts.

A parabolic mirror toy demonstrates how concave mirrors objects reflect light and produce a realistic image at their focal point. This resource probably doesn't explain any more than the printed insert that accompanies such an apparatus...

The concepts of refraction and reflection gel with your physical science class during this colorful exploration. Shining lasers through Petri-dish-shaped gelatin desserts, they will notice how the light travels and bounces off the sides....

When school and community leaders are at odds, what's a young person to do? Grouped pupils examine the details of a difficult situation during the 10th in a series of 12 leadership activities. Presented with a decline in community...

Investigate sound waves with acoustic mirrors. Using audio software, groups make recordings of musical instruments, both with and without acoustic mirrors. They compare the recordings to see the effect of acoustic mirrors on sound...
