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.

In this dramatic activity/demonstration about phase change and condensation, learners place an aluminum can filled with about two tablespoons of water on a stove burner.

In this activity, learners explore clouds and how they form.

In this activity, learners explore how air warms when it condenses water vapor or makes clouds.

In this activity, learners observe the water cycle in action! Water vapor in a tumbler condenses on chilled aluminum foil — producing the liquid form of water familiar to us as rain and dew.

In this chemistry activity, learners observe a combustion reaction and deduce the components necessary for the reaction to occur.

In this activity, learners conduct three experiments to examine temperature, the different stages of the water cycle, and how convection creates wind.

In this activity about phase change and condensation, learners boil water in an empty pop bottle in the microwave.

In this activity, learners observe the effect of transpiration as water is moved from the ground to the atmosphere.

In this activity/demonstration, learners observe what happens when two ping pong balls are suspended in the air by a hair dryer. Use this activity to demonstrate how rain drops grow by coalescence.

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

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 will simulate the processes of the water cycle at home in a plastic sandwich bag.

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