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

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

In this sunny day experiment, learners measure and compare how quickly light and dark colored materials absorb heat.

In this activity, learners visualize the differences in water density and relate this to the potential consequences of increased glacial melting.

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 activity, learners observe how salinity affects the freezing point of water by making and enjoying ice cream.

In this activity, learners conduct an experiment by heating an aluminum can filled with water to investigate air pressure.

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 observe the effect of transpiration as water is moved from the ground to the atmosphere.

In this fun hands-on activity, learners use simple materials to investigate evaporation. How can the evaporation of water on a hot day be used to cool an object? Find out the experimental way!

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 observe the hydrologic cycle in action as water evaporates and condenses to form rain right before their eyes.

In this activity, learners create a biosphere in a baggie.

Learners explore the variables that affect the properties of ice and the places where different types of ice are found.

In this activity, learners practice the steps involved in a scientific investigation while learning why ice formations on land (not those on water) will cause a rise in sea level upon melting.
