In this activity, learners investigate color vision as well as plan and conduct their own experiments.

In this activity, learners explore how the power of the sun can be harnessed to heat and cool a building.

Learners demonstrate how water can distort, refract and magnify light.

In this fun, hands-on autumn activity, learners experiment to discover whether the colored substances in leaves can be separated from the leaves.

In this four-part activity, learners will discover the exciting world of light--the most important form of energy in our world--and be able to identify and describe different types of light.

In this laboratory experiment, learners explore how effectively different sunscreens protect yeast cells from damage caused by ultraviolet (UV) radiation.

This activity (located on page 3 of the PDF under GPS: Light and Color Activity) is a full inquiry investigation into mixing colors with light.

This is an activity to do when there is a solar eclipse!

This lesson focuses on two simple activities that younger learners can do to gain an appreciation of nanotechnology. First, learners measure their hands in nanometers.

In this activity, learners investigate the sense of sight and develop and conduct their own experiments.

In this hands-on activity, learners investigate the functional design of leaves on a tree.
