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 related to nanotechnology, learners observe some of the effects that result from creating a thin layer of material several nanometers thick.

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

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 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 activity, learners arrange triangles together to make patterns to create paper quilts. Learners experiment with arranging the triangles in different ways to make various designs.

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

In this activity, learners repeat patterns in two and three dimensions to create tessellations. This activity combines the creativity of an art project with the challenge of solving a puzzle.

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

In this activity, learners repeat patterns in two and three dimensions to create tessellations.

In this activity, learners design unique tiles and make repeating patterns to create tessellations. This activity combines the creativity of an art project with the challenge of solving a puzzle.

In this activity, learners discover how to rotate a flat shape into the third dimension. Learners draw and cut out a shape that has at least one straight edge on an index card.

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.

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 math activity, learners experiment with the concept of symmetry.

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 build inexpensive kaleidoscopes using transparency paper and foil (instead of mirrors).
