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

This warm weather activity introduces learners to the impact trees have on blocking the sun's heat and reducing temperature on the Earth's surface.

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

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

In this weather activity (page 4 of the PDF), learners will explore the water cycle through an interactive game.

Did you know that the water we use today is the same water found on Earth millions of years ago? The Earth constantly uses and recycles water in a process called the water cycle.

In this outdoor activity, learners compare the moisture released from different kinds of leaves and from different parts of the same leaf, by observing the color change of cobalt chloride paper.

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 act as water molecules and travel through parts of the water cycle to discover that it is more complex than just water moving from the ground to the atmosphere.

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

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