Water Purification by Evaporation and Condensation
This easy-to-perform demonstration shows students how the water cycle, specifically the processes of condensation and evaporation, purifies Earth's water supply. Just mix up some water, dirt, and gravel in a glass bowl, place a cup in...

Water Temperature
Water temperatures connect to the movement of the ocean. Pupils read two articles about the temperature and the motion of the oceans before small groups investigate the interaction of hot and cold water. Team members add cold and hot...

Water Cycling in the Wilderness: Alaska quarter reverse
The Alaskan wilderness contains every imaginable element of the water cycle: it has flowing streams, cool spring rain, and frozen glaciers. Pupils use a series of worksheets to identify and define evaporation, condensation, and...

The Water Cycle (Evaporation, Condensation, Precipitation)
The 3 steps of the water cycle, evaporation, condensation, and precipitation, are the focus of this lesson. After a neat demonstration of rain using hot water, a pie tin, and ice cubes, young scientists observe and discuss the elements...

Heat Up and Cool Down
Don't be so dense! Using food coloring, pupils conduct two experiments with the difference in densities of hot and cold water. In the first experiment, learners add dyed hot and cold water into room temperature water and observe how the...

Can Gases Dissolve in Water?
Why does soda fizz when opened? Learners discuss the appearance of bubbles in soda bottles when opened. In groups, they design and complete an experiment comparing the amount of carbon dioxide dissolving in cold versus hot liquids.

Molar Heat of Fusion for Water
How can you describe heat of fusion in a way the class understands and relates the importance of this concept to present day issues? In this third activity of the series, learners conduct an experiment, demonstrating the flow of heat...

Temperature Affects Density
Different substances can have different densities, but can the same substance have different densities? Lesson explores the effect of temperature on the density of water. Extension idea connects the concept of how melting ice in lakes...

Changing State: Condensation
When you have a cold drink and you notice the water forming on the outside, it is literally pulling the water from the surrounding air to form the condensation. After watching a demonstration of condensation forming on a glass,...

Smoke on the Water
How do clouds form? Learners demonstrate the formation of clouds and the water cycle by testing four different setups in a plastic bottle. They identify the key components of a cloud to help them understand the process of cloud...

Hot and Cold Colors
Students engage in an activity that will allow them to observe that hotter conditions can speed up changes in materials. They will predict whether food coloring disperses more quickly in hot, cold, or room temperature water, and then...

Hot, Cold, Fresh and Salty
Students observe the effects of layering water and what is more or less saline than normal. For this geoscience lesson students create saline solutions, layer them and observe how the water becomes different temperatures in different...

The Water Cycle
Fifth graders identify organisms and processes involved in three cycles: the water cycle, the carbon cycle, and the nitrogen cycle. They produce a pictorial or abstract water cycle, and appropriately place life forms onto an existing...
