Using two baby food jars, food coloring, and an index card, you'll 'marry' the jars to see how hot water and cold water mix.

Making liquids of different densities to perfectly lay on top of each other can be a frustrating exercise. The Exploratorium created this activity as a fool proof way of making a density column.

In this chemistry meets cooking activity, learners compare the stability of egg white foams with various additives.

Build a hydrometer (measures the density of a liquid) using a pipet or eyedropper.

In this activity, learners use heat to separate zinc and copper in a penny. This experiment demonstrates physical properties and how physical change (phase change) can be used to separate matter.

This is an activity about friction as well as kinetic and potential energy.

In this activity, sodium acetate hand warmers are used to introduce learners to supersaturated solutions, crystallization, and exothermic reactions.

This activity about density provides instructions for making a miniature "lava lite" with just salt, oil, water, and food coloring.

This activity shows learners (with adult supervision) how to make a Glitter Globe, a fabulous toy that shimmers when you shake it.
