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.

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.

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

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.
