In this activity, learners create a water prism to break light into the seven colors of the rainbow.

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 activity, learners explore how pictures change in curved mirrors. Learners make cylindrical mirrors by wrapping Mylar around soda cans.

In this activity, learners will explore light with reflective surfaces. Learners will make predictions and share their observations as they experiment with directing a beam of light.

In this activity, learners explore how mirrors reflect light and change the way we see things.

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.

In this activity, learners make optical fibers out of strips of gelatin.

In this activity, learners construct a projector out of cardboard to view their favorite images (such as storybook illustrations) on the wall.

In this STEAM activity, learners create a "pixel tube" to explore reflections of light and color mixing.

In this activity, learners construct a device that projects images onto a surface, so they can trace landscapes and other sights.

In this optics activity, learners build a spy tool to secretly view things over walls or around corners.
