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

Learners add two dyes to mineral oil and water, and then compare their miscibility (how well they mix) in each.

Learners add drops of alginate solution to a solution of calcium chloride. The alginate does not mix with the calcium chloride, but forms soft gel beads.

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

In this activity (on page 2 of PDF), learners mix oil and water. Then, they add soap and observe what changes! The activity demonstrates how oil and water don't mix, except when soap is added.

Learners observe a bottle containing water and oil. They are invited to pick up the bottle and mix the contents together.

In this art meets chemistry activity, early learners discover the almost magical absorbent properties of salt while creating ethereal watercolor paintings.

Using yeast, sugar, and water, learners create a chemical reaction which produces carbon dioxide (CO2) gas inside a 2-liter bottle. They use this gas to inflate a balloon.

Learners mix liquid water with solid cornstarch. They investigate the slime produced, which has properties of both a solid and a liquid.

In this activity, learners investigate the process of osmosis by adding salt to a sealed bag of raw carrots and comparing it to a control.

In this activity (on page 2 of PDF), learners create a low-tech refrigerator that requires no electricity to keep food from spoiling.

In this activity, learners add dilute bleach solution to water that has been dyed with yellow, blue, and green food color.

In this experiment, learners will conduct chemical and physical tests to identify mystery substances.

Learners use a simple process to extract DNA from strawberries.
