In this activity, learners experiment with creating various types of bubble solutions and testing which ingredients form longer-lasting bubbles.

In this simple demonstration, learners investigate the properties of air pressure. Learners place an index card on top of a glass full of water, then invert the glass.

Young learners investigate and observe the properties of three liquids -- water, vegetable oil, and corn syrup. They use their senses to collect data and ask and answer questions.

In this activity, learners create a gelatinous slime using guar gum powder and borax. Educators can use this simple activity to introduce learners to colloids.

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, learners heat ice and water of the same temperature to get a hands-on look at phase changes. This is an easy and inexpensive way to introduce states of matter and thermodynamics.

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

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

Make a quick and easy filter from household materials. A filter will catch any solids suspended in a liquid and filter them out. By using a filter, learners can discover amazing things.

Learners initially test to see how many drops of liquid (water, rubbing alcohol, and vegetable oil) can fit on a penny.

This interactive demonstration reintroduces learners to three states of matter (solid, liquid, gas), and introduces them to a fourth state of matter, plasma.

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

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.

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

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

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