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

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

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

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 related to nanotechnology, learners observe some of the effects that result from creating a thin layer of material several nanometers thick.

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 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

In this activity, learners use earthworms as "unknown creatures" from the South American jungle to find out how animals use senses.

In this lab (Activity #1 on page), learners explore how we see color.

In this activity, learners explore how mirrors reflect light and change the way we see things.

In this activity, learners set up an experiment to investigate the effects of hot air on the path of a laser beam.

In this outdoor activity, learners use only their senses to to find the extremes of several environmental variables or physical factors: wind, temperature, light, slope and moisture.

In this outdoor, winter activity, learners find living green plants under the snow and determine the light and temperature conditions around the plants.

In this activity, learners explore conservation of energy by experimenting with a solar cell light device.

In this activity about bones (page 12 of PDF), learners investigate and compare the weight-bearing capacity of solid and hollow cylinders.

Using zebra mussels (Dreissena polymorpha), elodea and an indicator dye, learners study the role of light in photosynthesis.
