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.

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 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 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

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.

This is an activity (located on page 3 of the PDF under Butterfly Wings Activity) about how visible light is affected by tiny nanoscale structures, producing iridescence on butterfly wings, soap bubbl

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