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...

Turn up the heat. Individuals conduct two experiments to observe the difference between heated water and air versus cold water and air. Using food coloring, pupils observe the movement of the molecules in the two temperatures of water. A...

The introduction to the instructional activity mentions a sailor's limited capacity to store drinking water on his ship. Pupils then set up an overnight experiment to remove freshwater from salt water by distillation. There is a math and...

In lab groups, young scientists place aluminum cans with a bubble-solution cap into different temperatures of water to see what size of bubble dome forms. As part of an atmosphere unit in preparation for learning about convection...

Curious physical scientists follow a activity on the properties of water with this activity on distillation. They observe a miniature water cycle model that filters dirty water into clean water. These two lessons combined are an...

In this Looking at the Water Cycle worksheet, read an explanation of the water cycle and fill in missing words. Students also create a poster about the water cycle, deliver a weather forecast, and research further questions.

Tired of waiting for hot water? Groups of three determine the efficiency of an electric water-heating device. They calculate the amount of energy it takes to heat the water and the theoretical amount of energy required to heat the water....

Learners brainstorm on ways they use water, and where water comes from. They view video, Down the Drain, to gain specific facts about water use, properties of water, problems of water and the water cycle. They perform a lab activity...

The basic elements of the water cycle and how water is recycled through our environment is focused on in this lesson. Your students construct classroom terrariums and learn to make and record observations relating to the water cycle....

Students explore the water cycle and associated phase changes. They predict what happens to the mass of an ice cube in a Ziploc bag, discuss and act out phase changes and diagram the water cycle.
