In this activity, learners explore what happens when polarized white light passes through a sugar solution.

In this activity, learners use simple materials to create giant bubbles.

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.

This is a quick activity (on page 2 of the PDF under Stained Glass Activity) about the "Tyndall effect," the scattering of visible light when it hits very small dispersed particles.

In this activity (posted on March 12, 2011), learners follow the steps to construct a spectroscope, a tool used to analyze light and color.

In this activity, learners explore chemiluminescence and fluorescence. Learners examine 3 different solutions in regular light, in the dark with added bleach solution, and under a black light.

In this activity, learners make a photographic image—without a camera!

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

Learners mix a solution of luminol with hydrogen peroxide to produce a reaction that gives off blue light.

This is an activity (located on page 3 of the PDF under Stained Glass Activity) about nanotechnology making its way into everyday products, such as sunscreen, and how effective these invisible particl

In this activity, learners make a photographic image--without a camera!

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

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

This activity provides an opportunity for learners to observe and examine how carbon dioxide, water, and light produce glucose/starch through a process called photosynthesis.

This is an activity about turbidity, or the amount of sediment suspended in water.
