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

Learners observe a flask with a balloon attached over the mouth and inverted inside the flask.

Learners create beautiful fluid motion. They explore fluid dynamics, surface tension, solubility, and buoyancy while mixing liquids together.

This kinesthetic science demonstration introduces learners to four states of matter: solid, liquid, gas, and plasma.

In this activity, learners add different liquids to water and apply their working definition of “dissolving” to their observations.

In this activity, learners heat and cool carbonated water to find out whether temperature has an effect on how fast the dissolved gas leaves carbonated water.

Learners identify an unknown liquid by comparing its behavior to known liquids. Learners drop liquids onto different surfaces and see how the liquids behave.

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

Learners experiment with a commercially available liquid-crystal coaster. They warm the material with their hands for varying lengths of time and observe the changing colors that result.

In this activity, learners separate a mixture of pebbles, salt crystals, and wood pieces. They add water and pour the mixture through a strainer.

In this activity, young learners will experiment with a basic chemical reaction and observe what happens when gas gets trapped! Activity includes step-by-step instructions, safety notes and more.

In this activity, learners make colored sugar and add it to water, alcohol, and oil to discover some interesting differences in dissolving.

This activity has learners observe water and compare it to other liquids.

Learners investigate how the temperature of water affects its density.

In this activity, learners test different food items by timing how long it takes each liquid to slide from the top of a ramp to the bottom.

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

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.

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

In this activity, learners observe a quick phase change as water rapidly goes from a liquid state to a solid state.

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