Almost done

Our research is coming along great! Most everyones research is done. One member of our group is almost done with their project but they have to record their data in their logbook. They still have to take the alluminum foil off of the plants. Another member of our group still has to average all of their data. When they are done with the averaging they can start on the final report. The last member of our group is done with all of their data collecting and just needs to type up the final report. When everyone is done doing their individual reports we need to work on the group presentation. We are going to do a slide show with graphs and the pictures of the trees and plants that we took.

Cray Crazy Update

It is a new season and we have realized it is harder to catch crayfish. Our project will be done in a week from now. Last time we were out we made a lot of progress. Now we will only have to go outside one more time, which is today. After a quick scan of aour data it looks like crayfish prefer rocky bottoms.
OUR TEAM WILL GIVE OUR LAST UPDATE AFTER WE ARE COMPLETELY FINISHED WITH OUR PROJECT!

Simple Life--Protists

I am finally getting around to posting. I have been too caught up in my project (O_o) lately!
Actually...
I am done collecting my data. The past two months or so have been filled with going down to the creek, collecting samples, viewing them under the microscope, and sketching what I see in my field of view. The samples came from three different areas each of the three trials.
A=squeezed from the PF block
B=deeper water (pool)
C=shallower water (riffle)
I decided whether or not the protists I saw were algae (plant-like) or protozoa (animal-like) and made a still-incomplete table of that data. Now I am working on typing up my final report.
I have also discovered that my original hypothesis is not supported at all by the collected data. In the beginning, I thought that the most protists, would be found in sample A; however, after viewing all the samples, C is actually the one with the most algae AND protozoa. I thought this was interesting and wonder why this is so.

Murky Waters Moving On

We have now completed 4 tests and we are getting ready to start wrapping up the project. We have 4 test sites, site 1 is the farthest away from the dog park located next to a small culvert, site 2 is located write next to the dog park, site 3 is located on the main creek where the water always looks clearest, and site four is second furthest away from the dog park where the water always has a rusty look. Site 2 has had the highest coliform count on 3 of the four occasions, leading us to believe the hypothesis is correct.

Leaves, Trees, and Wannabees Update!

We seem to have been so busy lately that our blog reports have not been updated diligently. The group that is working with lichens has gotten very far, along with our leaves correspondent. Also, the person mapping out the park has finally begun their work!
Lichens- We have nearly completed all of our data collecting in three different locations around the school grounds. Also, we have begun to write our observations in a manner that can be submitted to our instructor. Although we can not yet be sure of this, since we are not completely done, we believe that the majority of lichens grow facing the north. This, however, may not be accurate, since the light intensity was always strongest in the north, thus the amount of sunlight reaching the lichens may be an important factor instead of the direction.

Leaves- My leaf analysis is going well. I finished my first trial in December, and am now about to start my second. I am going to repeat the trial this week. For my first testing, I used pointsettas, and I am deciding whether to repeat my second trial with the same plant or use another common household plant. A chat with my instructor should clear this up.

Trees- So far, in my tree idntification, I have marked off ten trees to identify. I have also identified four out of these ten and have possibile identifications for all of them. In addition, I have made a calendar including all of my goals and due dates.

Crawfish

Now our data is 5=riffles, 8=runs, and 9=pools. So far more caryfish are found in pools. Since January 25 we haven't found as many crayfish as before, but they seem to have grown in size.

Macroinvertebrates

The macroinvertebrates are definetly more active in cool water. The latest test I took shows that few are caught in warm or hot water, but the same happens with cold water. The most macroinvertebrates were caught when the water was 10.8 C. This shows the temperature of the water macroinvertebrates like.
