The water topic that I
choose was how prescription drugs affect water and lake organisms. Today our
society is overrun by the use of prescription drugs; therefore our environment
is greatly affected by these pharmaceuticals. In order to become more knowledgeable
about my carbon footprint, I chose the topic most closely related to my impact
on the aquatic environment. I have learned that there are two main ways that
pharmaceuticals have become part of our environment: excretion and disposal. Through
the process of excretion, prescription drugs in your body exit into the wastewater.
People can also flush the unused medicine down the sink or toilet, which also
leads to the lake water, like excretion. Even if the pharmaceuticals are thrown
away, they end up in the dump and later seep into the groundwater. As the water
becomes contaminated, the organisms become feminized, causing sterile species,
and resulting in extinction. This topic is important to our society due to the
cleanliness and availability of our water and food sources. Consequently, if
proper disposal of prescription drugs is not taken seriously, our health will
be at risk.

Water Property Demo
In class today, we did our water
property demonstrations with our partners. The water property my group had was
pH and litmus paper. The pH is a scale that determines if a substance is more
acidic or basic. Our demonstration shows just that. We chose to demonstrate six
different substances and where they compare to water. Every
substance is acidic, basic, or neutral. That’s what we are trying to decide
with this lab and our topic. When we explained that the red paper turns blue
for bases and the blue paper turns red for acids, they could tell the
difference between substances. Then we went on to tell them about water and how
it applies to aquatic ecosystems. Pure water is neutral on the scale, neither
acidic nor basic. That helps define the property of water as classifying it as
neutral. This neutral property of water can be applied to the aquatic
ecosystems. Rivers, ponds, lakes, and wetlands are aquatic ecosystems that have
one thing in common, freshwater. Freshwater needs to be neutral in order for
the plant life and fish not to be affected. Having a high acidic level and a
high basic level can create bacteria causing the aquarium to be a harmful
environment. In conclusion, the pH level should remain mostly neutral to keep
the aquatic ecosystem a safe environment. The demo went as planned for the most
part. We weren’t quite sure on how was going to say what, how the other
students would do with the substances, or what order in which we would perform
our demo. Having said that, I would say that it went pretty well for us.
Aside from my demo though,
I enjoyed watching all the other demos. My favorite one was where they were
talking about specific heat of water. The balloon would burn with no water in
it, but wouldn’t burn with water in it due to a high specific heat of water.
Another fun one was where they talked about the mixture, solution, and
suspension. I liked how two substances could either mix or stay divided.
Another cool demonstration was the density with water, oil, and alcohol. They
colored the liquids in order to show how they all have different densities. One
floated to the top, the other in the middle, and the final at the bottom. I
also learned about adhesion and cohesion. Cohesion is where water only attracts
water, while adhesion attracts other substances. In addition, turbidity is the measure of relative clarity of a liquid. I thought it
was cool to learn about all these properties of water and enjoyed the
demonstrations.

Aquarium Set Up
Today
my aquarium set up went perfectly for my first time. The teacher went over how
we were going to set it up and then we were on our own. The first thing you
need in order to start setting it up would be an aquarium. My partner and I
chose our own tank that was a 10 gallon one. After we acquired a fish tank,
gravel was already in ours so we needed to clean it. We rinsed the gravel using
sieves, cleaned all the decorations, and then even cleaned the filter inside
and out. The filter was nasty to clean because it was so dusty. Once we were
done with all that, we cleaned the actual tank using no soap and a brush the
teacher gave us. We cleaned the aquarium twice because the water was dirty
after the first time. Everything was now clean so we added our decorations to
the aquarium and created hiding spots with them. The next step we took was
adding water to the aquarium, but it was hard because the bucket to carry the
water was heavy. We ended up having to ask a guy to help us. Since the water
was added, we followed the instructions to add dechlorinator and bacteria
supplement to the tank. Then we put the filter on and put water in it to run
correctly. The filter started working and our tank water was not cloudy, so we
didn’t have to start over! We finally finished by putting the lid on and
cleaning up the mess we made. It was overall and interesting process that we
successfully completed!

Aquarium Plans
I have never set up an
aquarium before, so this is new to me. I can either use a bottle or a fish
tank. I chose to use a fish tank and share it with one of my friends in the
same class. I don’t want to have a big aquarium because there is only going to
be two fish in it. My aquarium will have pretty gravel with cool decorations.
It will remind me of the one in “Finding Nemo” because if I had a fish tank I
always wanted it to look like that one. Maybe I will have a volcano that blows
bubbles just like it too! The question is, what fish will I have? Meg plans on
having a Beta, so I need a fish that will cooperate with it. I know for a fact
that I won’t have another Beta because they don’t get along. I might get a
Molly because it sounds cool. My goals for this aquarium are to keep the fish
alive and make sure the tank is kept well.
The
Molly will do well in this assignment because they are adaptable fish and live
well within a community. They would rather live in salt water, but they can
live in freshwater too. The only thing that is a downside is that the Mollies
grow to be four inches. They need a bigger tank reaching 15-20 gallons. So I
need rethink which fish I should have in my tank. If I do get a Molly fish, at
least I know that it will do well with the water and other fish.

Freshwater
In
class we did a round robin activity with different topics. It was interesting
to see all the different questions and answers that were discussed. Even though
they were unique and interesting, I can only remember my group’s question. We
had to come up with ways water is used. Of course there are the obvious uses,
like drinking water, swimming, showering, and rain. Then there are the ones
most people would not think of, like energy. Water is used for many things and
is a part of everyday life.
There
were many different topics for the round robin activity, but I just can’t
remember at the moment. Instead I will talk about freshwater uses, properties,
and ways to conserve our resources. When I think of freshwater, I picture the
lake and anything except the ocean. Freshwater is used for many things in the
world, even though it only makes up three percent of total water. Uses of water
include agricultural, industrial, household, recreational, and environmental
activities.
Water
does not only have many uses, but a lot of properties too! There is adhesion
and cohesion, buoyancy, surface tension, capillary action, density,
temperature, dissolved oxygen, hardness, ph, mixture, solution, suspension,
specific heat, solvent, solute, conductivity, turbidity, water cycle, and porosity.
Since water is used in many ways with its different properties, there are ways
we can conserve our freshwater. For example, choose landscape for your house
that is appropriate for the climate and then water is lessened. Save water and
take less time in the shower! You don’t need to take thirty minutes to shower.
Do laundry and dishes when the load is full. Another way to conserve water is
to eat less meat and buy fewer things. Turn off the tap water while you brush
your teeth or wash your face. The main thing is to RECYCLE though! We use so
much water each day so do the world a favor and do not waste water.
