Water: A Portfolio of Student Learning

1. Describe the evolution of NYC's sewage system. What were some of the challenges that the city faced in its development of a waste system?What are some challenges that still remain?

1. In what ways did New York City's location (surrounded by water!) allow it to become a major urban center of the world?  Include in your response the different roles that water played in New York's development throughout history.

1. What is an aqueduct? What makes the Croton Aqueduct an aqueduct?

An aqueduct is a conduit or artificial channel for conducting water from a distance, usually by gravity.  What makes the Croton Aqueduct an aqueduct is that it is the water where most of New York City get their water from.

2. Why was the Croton Aqueduct built? What need was it constructed to fulfill?

1. Using your water log (and average water use from the days you logged), calculate what your average water use per year might be. 

My average water use per year might be around 5,000 liters of water.  I came up with this calculation by using the water calculater and this told me my water footprint.

Water Cycle:

1. Why is the water cycle an important factor in one of the earth's process?

The water cycle is an important factor because without the water cycle, the Earth's process might be really different. The water cycle is what keeps our earth with water. No water cycle, no water on the Earth.

2. How does percipitation, condensation and evaportation play a role in the cycle?

1. How can we observe the cohesion and adhesion of water?  Give examples that an average person could understand.  Also, you might use counter-examples, of substances that don't display cohesion or adhesion.

Cohesion:
