In this activity, learners mix water, cooking oil, and liquid food coloring to create beautiful colored designs in a cup. Use this activity to explore liquid density and solubility.

In this chemistry activity, learners prepare two petri dishes, one filled with water and one filled with milk.

In this activity, learners add different liquids to water and apply their working definition of “dissolving” to their observations.

Learners design their own experiment to compare how well cocoa mix dissolves in cold and hot water. They will see that cocoa mix dissolves much better in hot water. Adult supervision recommended.
