In this activity (on page 2 of the PDF), the learner places a golf ball between salt water and colored fresh water. The golf ball is not as dense as the saltwater.

In this activity, learners discover the primary physical properties used to separate pure substances from mixtures.

Learners create hard water by mixing Epsom salt and water. Then they compare what happens when soap solution is mixed with hard water and regular water.

In this activity related to the human circulatory system (on page 10 of the PDF), learners observe the dispersion of a drop of food coloring in water, draw conclusions about the movement of dissolved

Learners apply their knowledge from a previous study to identify different liquids--water, corn syrup, and vegetable oil.

In this activity, learners will "paint" their own crystal artwork by creating a picture with a super saturated salt solution.

"Nature of Dye" allows participants to create their own dyes and art while exploring how chemicals interact and how these interactions can have real-world applications.

In this chemistry activity (on page 2 of the PDF), learners make a layered drink with liquids of different densities.

An estuary is a body of water that is created when freshwater from rivers and streams flows into the saltwater of an ocean.

In this sensory activity, young learners explore chemical reactions by making their own play dough from home.

In this activity, learners apply a dissolving test to known crystals to identify the unknown. Since the unknown is chemically the same as one of the known crystals, it should dissolve similarly.

In this activity, learners investigate whether having sugar already dissolved in water affects the speed of dissolving and the movement of sugar and color through the water.

In this simple activity (on page 2 of the PDF), learners make a crystal garden using salt, water, and a brick.
