Why is it important that some water be stored in ice or snowpacks? (See: http://www.proteacher.com/redirect.php?goto=5347)
Explanation Then, using a graphic organizer or table, chart the use of water in contemporary civilization (e.g. one family); extrapolate; leave a column open for long-term effects and issues. Finally, research and develop questions on the shortages of potable water and possible solutions.
Focuses on a particular aspect of experience and demonstrates conceptual understanding.
Questions: Does salt water act the same way as fresh water in the water cycle?
Activity: Place appropriate terms for water cycle in visual representation, as the one from the U.S. Geological Survey. (3 stage learning technique; identification, understanding, evaluation/explanation). See: http://www.proteacher.com/redirect.php?goto=5347
Elaboration
Challenge and extend conceptual understanding and skills through new, deeper, and broader activities.
Questions: What impact has civilization had on the water cycle? Are there dangers to irrigation or transforming arid areas into agriculutural areas? What about the polar ice caps?
Activities: Using gained knowledge, chart the amount of water it takes to grow a single hamburger, then research the number of burgers sold in your city; extrapolate to state, nation, etc. -- is this a good use of water?

Water Global Human Needs System Thinking and Transformative Social Systems in Sustainability It is a fact that above 70% of the surface of the Earth is water. However, the real issue despite the abundance of water is the availability of fresh water (Amanda, 2013). Of the total waters on Earth, 97.5% of this is salty water; this leaves only a 2.5% as fresh water. To add on this deafening fact, of all
Water Cycle Performance objectives Understanding the water cycle The cycle of evaporation and condensation that controls the distribution of the earth's water as it evaporates from bodies of water, condenses, precipitates, and returns to those bodies of water. The targeted students need to posses a prior knowledge of living things and general knowledge of the earth and the earth's physical settings. During this unit the students will have the opportunity of learning new terminology,
With this information, people can make informed decisions regarding the water they consume. Which additives are healthful? Which are not?
