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.

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.

This fun video explains how to make a batch of oobleck (or slime) and why this special substance is known as a "non-Newtonian" fluid. Watch as Mr.

In this activity about magnetism (page 13 of the pdf), learners will experiment with magnets to explore how water and other liquids affect the strength of magnetic fields.

In this introductory activity, learners discover that sugar and food coloring dissolve in water but neither dissolves in oil.

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

Learners carefully pour vegetable oil, water, and corn syrup in any order into a cup and discover that regardless of the order they are poured, the liquids arrange themselves in layers the same way.

In this playful, goopy activity, learners mix two liquids to create a solid (that sometimes acts like a liquid ), using basic household materials such as borax and glue.

"Sublimation Bubbles" allows learners to explore how some solid materials, such as dry ice, can phase change directly from their solid to gaseous form.

This activity (on page 2 of the PDF) features a recipe to create the stretchy polymer Flubber from Borax detergent, white glue, and water.
