In this optics activity, learners experiment with polarizers (small dark rectangles) to examine light intensity.

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

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

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 light and shadows by creating a lantern they can keep on their nightstand.

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

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

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 international citizen science activity, learners measure their night sky brightness and submit their observations into an online database.

In this optics activity, learners work in pairs to explore how mirrors work. Learners use tape to mark the angles needed to see each other's reflection in a wall mirror.

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

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

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

In this activity, learners test the Law of Reflection based on experimental evidence. Learners produce raw data and explanations based on their data: pencil tracings of incident and reflection rays.

Have you ever heard of a camera without a lens? In this activity, learners create a pinhole camera out of simple materials. They'll see the world in a whole new way: upside down and backwards!

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 explore how and why rainbows form by creating rainbows in a variety of ways using simple materials. Learners create rainbows indoors and outdoors.

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

In this activity, learners cut out and fold their own collapsible origami starshade, an invention that shields a telescope's camera lens from the light of a distant star so that NASA scientists can ex
