Learners experiment with a 2-liter plastic bottle containing water and four “divers." The divers consist of open, transparent containers with the opening points downward.

Learners observe a sealed container holding a clear colorless liquid. They shake the container and the fluid turns blue. When allowed to sit for a few moments, the fluid turns colorless again.

Learners mix a solution of luminol with hydrogen peroxide to produce a reaction that gives off blue light.

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

In this chemistry activity, learners witness an exothermic reaction, while making their very own, completely usable sidewalk chalk. This is also an excellent activity for exploring color mixing.

In this fun and delicious chemistry activity (page 1 of the PDF), learners will explore the difference between physical and chemical change by making homemade ice cream.

Visitors observe a graduated cylinder with a golf ball floating about halfway in liquid. The bottom half of the cylinder contains a concentrated solution of salt.

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

In this activity, learners investigate vitamin C.
