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

Learners investigate one factor affecting reaction rates: temperature. In a darkened room, two identical lightsticks are placed in water -- one in hot water and one in cold water.

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

In this activity, learners thread colored beads onto string. Each beach represent a process of the water cycle.

"What's in the Water" lets participants use tools to solve the mystery- what chemicals and compounds are in a sample of water?

In this activity, learners explore the concept of density-driven currents (thermohaline circulation) and how these currents are affected by climate change.

In this activity, learners explore how salt water freezes in comparison to fresh water.

In this activity, learners make a model of the hot water of a deep sea vent in the cold water of the ocean to learn about one of the ocean's most amazing and bizarre underwater habitats.

In this activity, learners are challenged to lift a floating ice cube out of a glass of water using just one end of a piece of string.

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 quick activity, learners observe how salinity and temperature affect the density of water, to better understand the Great Ocean Conveyor.

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

In this activity, learners add food coloring to hot and cold water to see whether heating or cooling affects the speed of water molecules.

In this activity, learners explore temperature changes from chemical reactions by mixing urea with water in one flask and mixing calcium chloride with water in another flask.

In this activity, learners examine the parts of a thermometer. After placing a thermometer in hot and cold water, learners look at molecular model animations of the liquid in a thermometer.

Learners design their own experiment to compare how well cocoa mix dissolves in cold and hot water. They will see that cocoa mix dissolves much better in hot water. Adult supervision recommended.

Learners observe a sealed test tube containing a small amount of solid stearic acid.

In this activity, learners heat and cool carbonated water to find out whether temperature has an effect on how fast the dissolved gas leaves carbonated water.

Visitors mix urea with water in one flask and mix calcium chloride with water in another flask. They observe that the urea flask gets cold and the calcium chloride flask gets hot.

In this activity, learners investigate the effect of heat on a reaction.
