Water Cycle Stories

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...

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,...

A micro-unit on the phase changes of water includes three laboratory activities. Junior scientists compare the densities of ice and water, and then they do the same for cold and warm water. They examine freezing and boiling temperatures....

General facts about Earth's water sources, human use, and the water cycle are outlined by this presentation. Slide three has a grammatical error and slide nine refers to the local watershed of the author, so you will need to make a few...

The oceans contribute 37 trillion tons of water to land masses in the form of rain and snow. The third in a four-part series from NASA show satellite animations highlighting the precipitation on Earth. The videos show the movement of the...

Explain the two-step process of photosynthesis to your high school biologists with a focus on the Calvin cycle. Using adorable animation, a video likens the cycle to a tiny, sustainable factory. Even though the enzyme-bird rubisco...

Be water wise! Science scholars learn the water cycle on a global scale in part seven of a 13-installment series. The hands-on interactive allows them to explore Earth's water storage, types of precipitation, and the cycling of water...

Dive into a lesson on the hydrosphere with this Powerpoint presentation. Building on prior knowledge of the water cycle, young scientists learn what happens to water after it falls as precipitation and explore the...

What a fresh approach to learning about water! Chef Jamika Pessoa explains the chemical composition of this vital compound, what happens when heat is added or removed, and how much water is contained in different organs and...

Take an energetic ride through the phase changes of a water molecule in a compact activity. Young scientists learn about the phases of matter and discover the role of thermal energy in governing phase changes while watching a short...
