We had been in our class making models of the water molecules. We were modeling the part of and their polar and non-polar effects. We learned that water is polar so it can stick to other non-polar objects. The way we modeled is that we stuck together magnets to represent the way water always finds a way to stick back together.
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 removal 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 man made pipe that has water travel through so that the water can get to us and we can use the water.
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.
341.452 liters
Record your water use on the sheets provided.

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.
We can observe the water by checking the water and see how it reacts. Cohesion if it just attracts or adhesion if they attracted based on their element.
