In this activity, learners explore the different salinities of various sources of water by taste-testing.

In this quick activity, learners observe how the added sugar in a can of soda affects its density and thus, its ability to float in water.

In this activity, learners investigate diffusion by creating underwater "fireworks" using food coloring, oil and water.

In this demonstration, learners observe the effects of air pressure. They will watch as marshmallows inside a bottle expand as a vacuum pump removes air from the bottle.

Perform this classic inertia demonstration to illustrate the transfer of potential energy to kinetic energy.

In this activity (2nd activity on the page), learners explore how the nose is responsible for part of the flavor we taste in food.

In this physics demonstration, learners are challenged to insert a straw the furthest into a potato.

In this chemistry demonstration, learners investigate the rule "likes dissolve likes" by combining three, immiscible liquids to create a colorful density column.

This is a highly visual demonstration that illustrates both the effects of density and chemical reactions.

In this introductory activity and demonstration, learners are introduced to the concept that different substances react chemically in characteristic ways.

In this activity, learners explore healthy choices related to the liquids they drink. The importance of water and milk as essential nutrients for a healthy body is the focus of the experience.

In this demonstration, adult learners create a lava lamp using beer and nuts! Use this pub-themed activity to demonstrate the effects of buoyancy and bubbles.
