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

In this three-part activity, learners conduct simple experiments to see how light refracts and reflects, and how colors of light affect what we see.

Challenge popular misconceptions, learners explore how a mirror actually reflects an image in this activity.

This hands-on astronomy activity allows you to create a “cutaway” telescope to clearly show how reflector and refractor telescopes work.

In this activity, learners discover that it is difficult to trace a curve by using its reflection in a mirror. Use this activity to discuss how the brain works.

This fun and simple hands-on astronomy activity illustrates the path of light as it reflects off of mirrors and how this is used in telescopes.

In this fun optics activity, learners explore principles of light, reflection (mirrors), and perception. Learners work in pairs and sit on opposite sides of a "two-way" mirror.
