Waste Water Treatment Lab 2
Abstract:
This is the summary of your project that you will put at the beginning of your paper. Generally when you
search for a scientific research paper, you read the abstract to get an idea of what the study was about
and whether or not it pertains to the research you need to do to for your study.
Paragraph 1
Summarize your experiment
What is the essential
question and
purpose of your
experiment?
What is a summary
of your
methods/procedure?
What were the
results of your
experiment?
What inferences
(conclusions) did
you draw from the
trends in your
results?
Introduction:
Write an introduction in paragraph form that follows the format on the graphic organizer for the
introduction. Use the reading and the notes. If you need to, look up other information on water
treatment systems, or remediation. Cite all your sources using APA format.
Materials:
You must come up with the materials you will use to purify your water. Suggestions: plastic water
bottles, 2 liter soda bottles, gravel, sand, coffee filters, tissue paper, pieces of cloth, plants, soil, grass
clippings.
Material
5 plastic water
bottles or 5 2liter soda bottles

Do background research using the materials that Ms. Hobson gave you and your notes to
familiarize yourself with different methods of remediation of waste water (such as sewage).
Work with your group to determine a mechanism to filter or purify 200 mL of waste water
(of unknown substance…yet ) that you can bring in to class/create in class using materials
that you brought in.
You will have 50 minutes in class to build your water purification treatment. Plan
accordingly.
Develop a procedure for Wednesday or Thursday. Write it below.
Come prepared (Wednesday or Thursday) with all your materials and ready to work.
Complete your water purifier.
Ask Ms. Hobson for the “waste water”.
Take 5 mL samples of the waste water initially for dissolved oxygen, pH, Nitrogen and
Phosphorus.
Slowly (in 50 mL parts) pour the waste water through your treatment system, until you
reach 200 mL.
Let your purifying device sit for one week.
Take 5 mL samples of the purified water for dissolved oxygen, pH, Nitrogen and Phosphorus.
If you feel confident, add your fish. Let your fish live in the purified water for 1 week.
In the meantime, analyze your data in your results.
Create your discussion.

Results:
Create a clustered column graph using your data for all three weeks for everything that you tested. Then
use it to create a graph in excel. Make sure there are captions.
