In this three-part activity, learners conduct simple experiments to see how light refracts and reflects, and how colors of light affect what we see.

In this activity, learners make prisms from gelatin. Learners then shine light through the prisms and discover what happens. This activity introduces learners to the idea of refraction.

In this activity, learners explore phosphorescence and how certain materials can absorb and store energy from a light source.

In this four-part activity, learners explore light and sound through a variety of hands-on investigations.

Have fun with additive mixing! Observe what happens when the three primary colors of light--red, green and blue--are mixed together, resulting in white light.

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.

In this activity about light, learners explore how water can refract light and change the way they see things.

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.

In this experiment, learners work in teams to investigate how the color of a surface influences its ability to reflect light and therefore heat.

In this activity, learners explore liquid crystals, light and temperature. Using a postcard made of temperature-sensitive liquid crystal material, learners monitor temperature changes.

In this optics activity, learners explore color by examining color dots through colored water and the light of a flashlight.

Learners observe different light sources, outdoors and indoors, using prism glasses (diffraction glasses) and color filters.

In this math activity related to light, learners assemble a photometer and use it to estimate the power output of the Sun.

In this activity, learners use a flashlight, a glass of water, and some milk to examine why the sky is blue and sunsets are red.

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

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

In this quick and simple activity about reflexes (at the top of the webpage), learners conduct a simple test to explore pupillary response.

In this activity, learners investigate the speed of chemical reactions with light sticks. Learners discover that reactions can be sped up or slowed down due to temperature changes.

In this activity, learners determine the necessary conditions for pea seed germination.

In this activity, learners compare and contrast different forms of luminescence by observing how chemiluminescence, phosphorescence, and fluorescence produce or emit light.
