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

Players take turns adding shapes made of three squares to a grid. They try to fit their shapes on the grid in a way that blocks the other player.

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 optics activity, learners explore how many objects they can see in a set of mirrors (hinged like a book) at various angles.

In this activity, learners create a cylindrical mirror to see themselves as others see them.

In this math lesson, learners explore transformations and quadratic functions through toothpick patterns.

In this math-based activity, learners model the intensity of light at various distances from a light source, and understand how astronomers measure the amount of sunlight that hits our planet and othe

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

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 explore how mirrors reflect light and change the way we see things.

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 activity, learners use a compact disc to make a spectrometer, an instrument used to measure properties of light.

In this activity, learners explore how polarizing sunglasses can help diminish road glare.

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 play a game and use pattern blocks to explore mirror images and reflection.

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

In this optics/mathematics activity, learners use two hinged mirrors to create a kaleidoscope that shows multiple images of an object.

In this activity, learners use a laser pointer, empty soda bottle, rubber plug and water to demonstrate total internal reflection.

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

In this physical sciences activity, learners use science to solve a "crime." Learners collect trace evidence (glitter) and explore its characteristics, such as color, size, shape, and light reflection
