In this activity, learners explore the different salinities of various sources of water by taste-testing.

In this activity, learners investigate and compare the rate of drying in different conditions.

In this activity, learners explore sublimation by conducting experiments with dry ice.

Learners build models to learn about the special cells and structures that plants use to move water from their roots up through the stems and leaves.

In this activity, learners calculate the number of milliliters of water a nearby tree transpires per day.

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 explore liquid crystal thermometers to observe how heat flows by conduction, convection, radiation, and evaporation.
