Dewey and Chemistry: The Water Cycle Revisited

Is artesian water designed to be better, or is it just from wells similar to those in the city of Artesium? This experiment looks at many different types of bottled waters, including artesian. Using a soap mixture, scholars test to see...

Explore the water cycle with a hands-on earth science activity that prompts pupils to measure the amount of water normally transpired by plants. After they describe the flow of the water cycle and provide examples of how human activities...

How do we affect the ecosystem, and what can we do to preserve it? Pupils explore chemicals that promote and inhibit plant growth, then discuss the importance of nitrogen and phosphorus to the survival of organisms and describe how...

Examine the behavior of energy as water freezes and melts. An engaging activity provides a hands-on experience to learners. Collaborative groups collect data and analyze the graphs of the temperature of water as it freezes and then...

Introduce biogeochemical cycles and goes into detail about the hydrologic and carbon cycles. A scientific video engages learners and teaches them at the same time.

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.

Students perform an experiment to measure the density of tap water vs. salt water.

Gorongosa National Park holds a fascinating and ever-changing landscape. What makes the water cycle in the park so special? Travel to Mozambique to learn more about the park using a short video. Content includes rainy season in the park,...

It's commonly known that over 70 percent of of the earth's surface is covered by water, but exactly where did it all come from? Join this short video as it travels back to the beginning of the universe in search of the origins of this...

Some aquifers took thousands of years to collect water, yet they have been depleted in only a hundred years. Viewers learn about where humans use water and the serious concerns for the future of the water supply in the second of 10...
