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

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

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

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 light and dark colored objects absorb the Sun's radiations at different rates.

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

In this two-part activity, learners explore the properties of liquid crystals, which are responsible for why mood rings change color.

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

In this activity, learners explore how mirrors reflect light and change the way we see things.

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