Another great resource is the Shoreline Public Library databases. There are encyclopedias and science specific encyclopedias that you can access on-line. If you have never used this resource, feel free to ask me or our school librarian, Ms. Gilman. We are happy to help!
What was provided in class -
the water plant was from Lake Washington, commonly referred to as seaweed, but its scientific name is: Elodea
the pond water was cultured by our biology team over the summer, it contains microorganisms called: Euglena
Each person in the group will be writing a report and submitting it individually to turnitin.com. Drawings and pictures do not need to be included in the turnitin.com submission
One person's report will be explaining the lab set-up, and will show labeled diagrams of the different levels.
One person's report will include research on the organisms in the pond level
One person's report will include research on the organisms in the middle level
One person's report will include research on the organisms in the top level
Here is what needs to be included in report #1
question (what is your manipulated variable?)
hypothesis (if you change this manipulated variable, the responding variable will do this because of this scientific explanation) Responding variables - you will be testing nitrate levels, pH, ammonia, maybe carbon dioxide, quantitatively. Qualitatively, you will be checking water clarity, health of food web, growth of autotrophs, condensation in middle level, etc)
variables defined - control variables
explanation of set up - procedure for how you are making sure that the only thing different between the ecocolumns is the manipulated variable
abiotic factors justified - did you add rocks, dirt? Why is it in there?
detailed, labeled diagram of set up
sources cited – (just 1, you will need to look up information on why you think your ecocolumn will respond a certain way to the manipulated variable)
Here is what needs to be included in reports 2-4 For each organism, include:
picture (taken by your group of your organism prior to putting into the ecocolumn)
common name, scientific name (Genus species, capitalize the Genus and have the species lowercase). Do your best to find at least the general Genus of the organism from one of the websites provided
description (tell me something about this organism that makes it different from other similar organisms)
geographical distribution (where is this particular organism typically found - examples
justification(why did you choose to include this particular organism?)
For the entire level - include a food web Include a list of resources - at least 3. Start by using the websites provided by me. If you can't answer all the questions
Frequently asked questions: 1. Should we list the variables separately or identify them in the procedures? As for variables - they can be identified in your procedures or listed separately or both. Whatever makes more sense to you.
2. How do you define a successful ecocolumn? How you define a successful ecocolumn is part of your hypothesis. Remember that you are collecting data on the water - nitrates, ammonia, pH, as well as making observations about growth, water clarity, etc. Make predictions of what you think you might observe over time.
3. Can we turn in one bibliography as a group? The written report is completed individually so you don't pull everyone's sources together. I would like to know what resource was used for each organism by each person.
4. Even though we are submitting papers separately, can we share pictures? Yes!
5. What are the names of the organisms that were provided in class? -the water plant was from Lake Washington, commonly referred to as seaweed, but its scientific name is: Elodea -the pond water was cultured by our biology team over the summer, it contains microorganisms called: Euglena
6. It is Monday night and I can't figure out the actual name of the plant, bug etc. What do I do? If you are freaking out about the name of the organism - first breathe! It will be okay. Find an organism that can be found in the place you found and that is a similar size and use the organism's information. If you are wrong - you will get some feedback so you can fix it for your final presentation. For this written report, you would still get credit for doing the research.
7. If we have a group of three, how do we turn in the first report? Since your group is splitting up the first report, just add those components that you are responsible for to your own report. Remember that pictures do not need to be submitted to turnitin.com. It is fine to attach pictures to the end.
