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

In this activity, learners create a water prism to break light into the seven colors of the rainbow.

In this optics activity, learners explore why the sky is blue and the sunset is red, using a simple setup comprising a transparent plastic box, water, and powdered milk.

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

In this activity, learners make their own heat waves in an aquarium.

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.

In this activity, learners explore color, light and shadow by creating their own puppets to hold in front of a light source.

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

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 sublimate dry ice and then taste the carbon dioxide gas.

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

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 discover how sediment is affected in an oil spill. Learners investigate the differences between heavy and light oil as well as the differences between different sediments.

Working in groups, learners model the continuous destruction and creation of ozone (O3) molecules, which occur in the ozone layer.

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 technology activity, learners light up the room with electrifying play dough creations. Learners use conductive and insulating homemade play dough to build simple circuits.

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

In this demonstration, adult learners create a lava lamp using beer and nuts! Use this pub-themed activity to demonstrate the effects of buoyancy and bubbles.
