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

In this optics activity, learners use glass and water to demonstrate total internal reflection (TIR).

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 trap a thin layer of air between two pieces of Plexiglas to produce rainbow-colored interference patterns.

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 (page 1 of the PDF under SciGirls Activity: Horse Ears), learners observe how an animal responds to its own 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

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

In this optics activity, learners explore how they can make gelatin stop light, but not stop them from seeing fruit suspended within.

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 quick activity, Dracula has a hole in his house and learners help solve the problem by using a mirror and protractor to reflect incoming light out of his house.

In this activity, learners explore how light and dark colored objects absorb the Sun's radiations at different rates.

In this sunny day activity, learners compare how a cup of water and a cup of tonic water reflect or refract light in the sun.

In this activity, learners construct a device that allows them to look over ledges or around corners.

In this optics activity, learners split white light into all its component colors using three household items: a compact disc, dishwashing liquid, and a hose (outside).

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