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

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, learners explore the difference between compact fluorescent light (CFL) bulbs and traditional incandescent bulbs.

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 math activity related to light, learners explore why a light, such as a candle or a streetlight, looks dimmer the farther away from it we get.

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

In this two-part activity about luminescence, learners explore the chemistry that happens inside glow sticks and other light producing reactions.

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

This is an activity (located on page 131 of the PDF) related to sleep and circadian rhythms as well as space travel.

In this food science activity, learners conduct an experiment that demonstrates the importance of light to plants.

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

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

Can gelatin (like Jell-O ®) change the speed of light?

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

In this space science activity, learners explore transits and the conditions when a transit may be seen.

In this data collection and analysis activity, learners evaluate fish physiology and ecology using vision research data from Dr.

The major goal of this math lesson is to have learners collect data from a variety of experiments, determine what models best fits their data, and explain why their models are best.

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.

In this pencil and paper activity, learners work in pairs and simulate how astronomical spacecraft and computers create images of objects in space.

In this physical sciences activity, learners use science to solve a "crime." Learners collect trace evidence (glitter) and explore its characteristics, such as color, size, shape, and light reflection
