Water: A Portfolio of Student Learning

Rain & SlideIn this picture, we are doing a experiment that shows what happens when rain, rains on the mountains. It slides down to a lake or pond or river.Pull! In this picture, we are pulling up the sails. It was fun but hard work.

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?

  Well now we have a sewer systems which take all of our wasted water into another place. Some challenges is that since we waste like billions of water everyday, there might not be anymore water(fresh) left. When we waste,litter,and etc, we cause global warming. Which also melts the glaciers so there won't be that much fresh water.

 

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.

Well at the 1700's and 1800's they made a port. It was great for trading, selling, and buying. Soon tons of people came to New York and it was one of the most poplulated state in the world. The water helped New York travel so they can ship goods. Such as food, jewlery, and silk.

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

An aqueduct is a bridge that carries water from 1 place to another. It carries water from ossinging to New York.


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

It was build because everyone was getting bad dirty water. And this aqueduct would run clean drinking water. They needed 90million bricks. They used more than 4 million cash.

 

 1.  Using your water log (and average water use from the days you logged), calculate what your average water use per year might be.  219,000 a year 2. What is your estimated water footprint as found using the water calculator on www.waterfootprint.org? (Express in both cubic meters per year and liters per year)   Does this surprise you in any way? Why?

1. What can you tell me about acids, bases and testing?

•  An acid has a sour taste. An bases has an bitter taste. Testing is to test the pH of any liquid and determining its range from 0-14. 

2. What are the differences between acids and bases?

•   The difference between acid and base is that acid is a pH reading that is lower than 7 (1-7). A bases is a pH reading that is higher that 7(7-14).
   

3. Why might it be important to test water based on the acidity?

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

•   The water cycle is important because if there wasn't a cycle, the earth would soon run out of water. Then earth will be like mars.

2. How does precipitation, condensation and evaporation 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
   
    We could make an experiment that shows cohesion and adhesion. Then we can observe it and make notes. One experiment might be using some magnet marbles(like we did in class) and put it in a metal pipe. The water will be the magnet marbles and then you can see how it sticks. Since is when it sticks togther.
