In this art meets science activity, learners pack silver, ball-shaped ornaments in a single layer in a box to create an array of spherical reflectors.

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

In this hands-on activity, learners build their own kaleidoscopes and explore how light can reflect of off surfaces such as mirrors, to produce beautiful patterns.

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

In this activity, learners use transparent tape and polarizing material to create and project beautifully colored patterns reminiscent of abstract or geometric stained glass windows--no glass required

Learners observe different light sources, outdoors and indoors, using prism glasses (diffraction glasses) and color filters.

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

In this activity, learners investigate color vision as well as plan and conduct their own experiments.

In this activity, learners use pattern blocks and mirrors to explore symmetry. Learners work in pairs and build mirror images of each other's designs.

Create 3D glasses and use them to explore color, light and optics. Fool your brain into 'seeing' three dimensions on a flat surface!

In this math activity, learners experiment with the concept of symmetry.

In this activity, learners investigate the reflective properties of light and mirrors as they make a kaleidoscope.

In this activity, learners build inexpensive kaleidoscopes using transparency paper and foil (instead of mirrors).

Have you ever heard of a camera without a lens? In this activity, learners create a pinhole camera out of simple materials. They'll see the world in a whole new way: upside down and backwards!

This fun activity uses simple materials such as milk cartons and mirrors to introduce the ideas of optics and visual perception.

In this activity, learners construct a device that allows them to view 2-D images in 3-D.
