Learners explore three-dimensional geometric frames including cubes and tetrahedrons, as they create bubble wands with pipe cleaners and drinking straws.

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 discuss and investigate how cameras, telescopes, and their own eyes use light in similar ways.

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

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

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 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.

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

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

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