Learners are challenged to discover the relative densities of colored liquids to create a rainbow pattern in a test tube.

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 use pop-beads to understand the characteristics and properties of polymer chains.

In this chemistry lab activity, learners model the colors of fireworks by burning metallic solutions in a flame and observing the different colors produced.

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.

Learners experiment with a commercial photo-sensitive paper (Sunprint® or NaturePrint® paper). They place opaque and clear objects on the paper and expose it to bright light, observing the results.

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.

Everybody loves bubbles, and this is the best bubble recipe ever!

Learners experiment with water gel crystals, or sodium polyacrylate crystals, which absorb hundreds of times their weight in water. When in pure water, the water gel crystals cannot be seen.

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

In this activity (pages 32-41), learners learn how the atomic and molecular arrangement of matter are related to physical properties.

In this simple chemistry activity (page 1 of PDF under SciGirls Activity: Colorblind Dogs) about acids and bases, learners will mix a baking soda and water solution and use it to paint a message on a

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 written as a display, but can easily be adapted to a hands-on activity. Learners observe and shake containers of shiny liquids.

In this art meets chemistry activity, early learners discover the almost magical absorbent properties of salt while creating ethereal watercolor paintings.

In this activity on page 8 of the PDF, learners investigate vitamin C. Learners conduct a chemistry experiment to determine if Tang drink mix or orange juice contains more vitamin C.
