Water, Water Everywhere

Junior geologists, hydrologists, or meteorologists simulate what happens during the flooding of a river and demonstrate factors that contribute to flash flooding. This outstanding resource provides a vocabulary list, online resources,...

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...

Small groups place sand and ice in a covered box, place the box in the sunlight, then observe as evaporation, condensation, and precipitation occur. These models serve as miniature water cycles and demonstrations of the three phases of...

Humans are quickly depleting Earth's fossil fuels and locating them is becoming increasingly difficult! Layered muffins are used for models as young geologists take core samples in order to determine the presence of oil. Consider first...

One of water's claims to fame is as the universal solvent. Young physical scientists experiment to discover which materials dissolve in this special compound. You could never be more prepared for teaching this lesson than by using this...

The water cycle is one of earth's most easily observable processes, but demonstrating each step within classroom walls can be a challenge. Through a series of videos and quick demonstrations, cover each aspect of the hydrologic cycle in...

Take young scientists on a trip through the water cycle with this interactive science activity. After setting up a series of ten stations representing the different places water can be found, children use the included printable dice to...

Learners study floods and flash floods. The About Floods page explains the difference between floods and flash floods, and why flash floods occur. The Flood Types page explores some of the different types of floods that occur. There is...

There's nothing quite like a glass of ice-cold, freshly squeezed lemonade. Lesson seven of this series explains how the water humans need to survive can come in many forms. Teach your class about how much water humans require every day...

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...
