In this activity, a lightbulb is placed in front of a concave mirror. The actual lightbulb is not visible to the viewer, but the viewer can see the mirror image of the lightbulb formed in space.

In this activity, learners explore how nanosized structures can create brilliant color.

In this activity, learners explore the invisible infrared radiation from an electric heater.

Learners use two mirrors to explore how images of images of images can repeat forever.

In this activity about light and reflection, learners use a special device called a Mirage Maker™ to create an illusion.

In this activity about light and reflection, learners discover that what you see is often affected by what you expect to see.

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

In this demonstration, amaze learners by performing simple tricks using mirrors. These tricks take advantage of how a mirror can reflect your right side so it appears to be your left side.

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.
