In this video segment from ZOOM, two cast members repeat an experiment designed to separate fresh water from a liquid solution, this time using colored sugar water in one solar still and orange juice in another. The basic still design they employ tra...ps water vapor that is created when the Sun's heat causes water to evaporate. As the vapor cools, it condenses and trickles down to a collection container. Were they successful in their experiment this time? A final taste test reveals all. This video could also be used with a lesson about the scientific process and forming a hypothesis. Closed captioning included. Run time 03:55.

Freshwater seems abundant, but when accounting for all the water on Earth, it's in limited supply. Just three percent of the water on our planet is freshwater. A majority of this water, about two percent of the world total, is contained in glaciers a...nd ice sheets or stored below ground. The remaining one percent is found in lakes, rivers and wetland areas or transported through the atmosphere in the form of water vapor, clouds and precipitation. Rain and snowfall replenish freshwater sources, making it vital to know when, where and how much water is falling at any given time. Using NASA's Global Precipitation Measurement satellite, researchers can track precipitation worldwide and monitor levels from space. (02:49)

Water is the fundamental ingredient for life on Earth. Looking at our Earth from space, with its vast and deep ocean, it appears as though there is an abundance of water for our use. However, only a small portion of Earth's water is accessible for ou...r needs. How much fresh water exists and where it is stored affects us all. This animation uses Earth science data from a variety of sensors on NASA Earth observing satellites as well as cartoons to describe Earth's water cycle and the continuous movement of water on, above and below the surface of the Earth.

The water cycle is the constant movement of water through the Earth and its atmosphere. Water on the ground evaporates, becoming water vapor. The vapor rises, becomes clouds, and then falls back to the Earth as rain, snow, sleet, or hail. Learn mo...re about the water cycle with this cartoon animation from StudyJams. A short, self-checking quiz is also included with this link.
