In this activity, learners will observe laminar and turbulent flow of water using only a plastic bottle, liquid hand soap, food coloring and water.

Using two baby food jars, food coloring, and an index card, you'll 'marry' the jars to see how hot water and cold water mix.

In this activity, learners explore Boyle's Law and discover that water will boil at room temperature if its pressure is lowered.

In this activity, learners conduct a simple experiment to see how electrically charged things like plastic attract electrically neutral things like water.

In this activity, learners touch supercooled water drops with an ice crystal and trigger the water drops to freeze instantly.

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

In this activity, learners sublimate dry ice and then taste the carbon dioxide gas.

In this activity, learners make their own heat waves in an aquarium.

In this activity, learners experiment with surface tension using everyday household items such as strawberry baskets, paperclips, liquid dish soap, and pepper.

In this quick activity, learners drink Avogadro's number worth of molecules - 6.02x10^23 molecules!

In this physics activity, learners conduct two experiments to explore free-falling.

This activity shows you how to make amazing crystal spikes using Epsom salt and the sun.

In this activity, learners investigate convection by using food coloring and water of different temperatures.

If you got a big graduated or clear cylinder, water, a pipe, and a tuning fork, you've got a sound learning opportunity! Learn about resonance with this Exploratorium Science Snack.

This activity provides instructions for using cornstarch and water to make an ooze which has the properties of both a solid and liquid.

In this weather-related activity, learners make a portable cloud in a bottle.

In this fun gardening activity, learners discover their soil type. There are three basic soil types: sand, silt, and clay.

Electrolysis is the breakdown of water into hydrogen and oxygen. This Exploratorium activity allows learners to visualize the process with an acid-based indicator.

In this activity, learners construct a simple electrolysis device. With this device, learners can decompose water into its elemental components: hydrogen and oxygen gas.

In this activity, learners build a simple electrolysis device. Then learners use an indicating solution to visualize hydrogen and oxygen molecules in water.
