Of all the water on earth, how much is in the ocean or in glaciers or underground, and how much can we actually drink? Model and graph the Earth’s water distribution after playing a game that illustrates all the places where water can be found.
Program option: Your location
NGSS Disciplinary Core Idea:
Nearly all of Earth’s available water is in the ocean. Most fresh water is in glaciers or underground; only a tiny fraction is in streams, lakes, wetlands, and the atmosphere. (5th grade: 5-ESS2-2)
Water continually cycles among land, ocean, and atmosphere via transpiration, evaporation, condensation and crystallization, and precipitation, as well as downhill flows on land. (6th grade: MS-ESS2-4)
