Student Responses to Pre-visit Question:
"How do humans impact/interact with watersheds?"
The following list of responses to the above quesion come from 11th graders at Delaware Valley Friends School, Paoli, PA. They are participating in a Bryn Mawr College program called Fridays in the Lab sponsored by Howard Hughes Medical Institute. This program brings selected high school science classes such as Delaware Valley Friends School to the campus on four Fridays during the academic year for interactive laboratory demonstrations and short experiments.
These responses were part of a pre-visit assignment designed to introduce an aqautic monitoring study of Rhoads Pond and Mill Creek.


we can prevent trees from being killed and plant more trees and if we
plant enogh they will suck up enough water to impact how much water is
left in the sheds and if it continutes all the water can be sucked in to
the trees cause the rain cant fill the water shed qicuk enough


Humans impact watersheds by pollution that people put in the water.


Humans impact and interact with watersheds because of polution and
trash.


Humans impact watersheds by the way they treat their environment. Such as
trash blowing into the watershed, cars gas pollute the watershed.


humans impact the streem by puting drainadge lines into it and runoff from
the roads and poulute the streem with waste and runoff from farms and
lawns they interact with it by swiming in it or fishing in it
 Humans impact / interact with water sheads by do in activities such as: fishing, boating and
swimming in a lake. Humans also can impact a watershead and not know it
like when they drive past a river on a rainy day and a drop of oil falls
out of the car into a stream that goes into a lake witch will make the
fish sick.


Humans imapact and interact with watershed in many ways. Humans pollute
the water by using moter boats. Animals waist gets washed into the water
after it rains. Chemicals get washed into the rivers every day. We effect
is by every day activities. Driving, building houses, throwing away trash,
putting things on our lawns to make the grass go out to keep bugs out.
thax for listing to what i think!


Humans impact/ interact with watersheds. For starters they pollute the
water by leaving waste in the environment. They interact with the water by
boating and swimming in it. Chemicals get into water frequently because of
human's carelessness. This is not good.


humans interact with the watersheads in may ways, Some good some bad. The
good things that we do are, we clean the water and test it to make sure
that its ssfe for animals and humans. we also dumpthings such as trash,
oil and pooh. Having a farm, or building a new house could affect it to. A
farm house cows and animals. The cows and outher animal waist washes into
hte ground and into the stream. Other things affect the water sheads as
well just like acid rain, this can make the water to acidic, or to base
affecting the about of oxyging in the water which can creat fish kills. So
theres many things that we do that affect the water sheads and as befoer
some are good soame bad. ide just like to think that someday we can afect
the water sheads in a positive way.


Humans interact and impact with watersheds in many different ways. I
remember the first time i ever went to the watershed, i went in about
fourth grade with my elementary school, it was the Wissahickon Water Shed.
I know the many boats and trash are put into waters esp. at water sheds.
Many chemicals get washed into the water after rain falls. Other things
such as driving, building, trash, and simple things as just urinating.


Humans intercat and with the watersheds in many different ways some in
good ways and in negative ways.

first off  we are always effecting the water with our chemicals used on
our lawn and faields to kill bugs and pests but usualy those chemicals
find there way into the grownd and edventialy into the water effectivly
polluteing the water and killing the animals and organisms the live  in
it. 
but humans also interect wiht the watersheds in indestructive ways  usualy
in recreation  such as fishing  boating and swimming
this way both the organisms can coenside togethor.


Humans impact and interact with watersheds by polluteing the water around
the city and in all different places. When people throw their trash into
the water they pollute the water and mess it up Sometimes the rain
pollutes the water when it rains the dirt turns into mud and the mud goes
into the water and makes it all muddy.


i thinc that wen animels and humins have wast we inpac the woter shed


Humans have both good and bad impacts and interactions with water sheds.
In the schuykill, many people boat and fish. boating does not have a
negitive effect, unless powerboats are used which pump gasoline into the
water. Fishing is not harmful unless the area is overfished, in which case
the ecosystem can be hurt. One bad interaction people have is that they
throw trash into the river, which kills wildlife and makes it look ugly.


Humans interact with watersheds by fishing, boating, and crew running.
Humans impact it by dumping thier oil down the sewer drain, throwing trash
in the river and not caring for Mother Earth at all period.


Humans have impacted water sheds a lot over time by throwing chemicals,
human waste and trash into water ways for years without ever thinking of
the impact it will have. Despite trying to clean out some of these water
ways, many are still too poluted for animals to live in or drink from. I
remember my parents telling me when they were kids that they would go and
swim in the local lake or stream. Now swimming in natural bodies of water
is discouraged because there are usually bits of rusty metal, broken
glass, trash or chemicals in them, which no one wants their children
swimming in. Unfortunatly, most people don't care about how they are
poluting the air and water ways and that soon the O-zone layer will be so
thin that you won't be able to leave the house without sunscreen, so i
don't know when all of this is going to be taken care of and it will be
safe to drink from natural streams again.
