In this optics activity, learners create flip books by drawing an image like an eye opening and closing on 24 small pages of paper.

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

Learners examine the properties of light by experimenting with an LED-flashlight and polarizing filters. When two polarizers are used, they block all light when they are placed at right angles.

Learners experiment to see which colors of light will cause a phosphorescent (glow-in-the-dark) material to glow.

Learners shine the light of a laser pointer through sheets of fabric that all have a different number of threads per inch.

In this activity on page 13 of the PDF, learners use a laser pointer (with known wavelength of light) to measure the thickness of a human hair.

In this activity, learners will use Google Sky to observe features of the night sky and share their observations.
