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.

In this activity, learners investigate whether having sugar already dissolved in water affects the speed of dissolving and the movement of sugar and color through the water.

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

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.

Learners investigate how the temperature of water affects its density.

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.
