In this activity about water solubility and density, learners use critical thinking skills to determine why water can dissolve some things and not others.

In this activity, learners conduct a series of hands-on experiments that demonstrate how the working of plants' veins, known as capillary action, enables water to travel throughout the length of a pla

In this chemistry challenge, learners identify which plants have the enzyme "catalase" that breaks hydrogen peroxide into water and oxygen.

In this activity, learners observe how salinity affects the freezing point of water by making and enjoying ice cream.

The Ancient Egyptians used a naturally-occurring salt from the banks of the Nile River, called natron, to mummify their dead.

In this activity, learners burn a peanut, which produces a flame that can be used to boil away water and count the calories contained in the peanut.

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

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