This is an activity that demonstrates how batteries work using simple household materials. Learners use a pickle, aluminum foil and a pencil to create an electrical circuit that powers a buzzer.

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

This display shows the dangers of acid rain on buildings and other structures as two concrete bunny rabbits are disintegrated by sulfuric acid. Learners scrape chalk onto the concrete bunnies.

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 experiment, learners work in pairs to create two gloves -- one that contains a layer of shortening (blubber) inside, and one that doesn't.

This is an activity (on page 2 of the PDF under Bone Regrowth Activity) about the two main components of bone - collagen and minerals (like calcium) - and how they each contribute to its flexibility a

In this activity, learners explore how packaging engineers develop customized shipping and packaging containers to meet the needs of many different industries.

In this experiment, learners test multiple food items to see if they are an acid or base using an indicator solution created with red cabbage.

In this activity, learners simulate what happens to a human spine in space by making Sponge Spool Spines (alternating sponge pieces and spools threaded on a pipe cleaner).

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 laboratory activity, learners design an experiment to evaluate how environmental factors influence the growth of molds.

In this activity (on page 5 of PDF), learners use dry ice and household materials to make scientifically accurate models of comets.

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.

In this four-part activity, learners explore how the body works and the chemistry that happens inside living things.

In this activity, learners are introduced to challenges of maintaining temperatures while living in space.
