Furnace
Brook Lab Report
Introduction:
Testing the PH of water at Furnace Brook Creek. What’s a healthy PH for the
micro-invertebrates. Dissolved oxygen and nitrogen compound where to be
determined. Sampling this water told us the population of each species present
in the water with these conditions.
Research
Question: which location would have a healthier
environment; rocky and fast speed waters or non-rocky and low water speed?
Hypothesis: In fast moving waters there
isn’t enough time for any species alive to absorb or catch the nutrients or
daily necessities also the fact there is rocks or rough patches makes it even
harder to catch them. Verses slow moving waters and non-rocky.

Experimental
Setup: This experiment was done in shady areas near
Corcoran High School. Two different vials were used to measure the D.O. and PH.
The groups used Dissolve Oxygen tablets and potential hydrogen tablets also. The
students within these groups should have found out or known that a healthy PH
of 7 is reasonable to sustain life.
Procedure:
1. Get
into groups
2. Using
a LaMotte kit filled with the following
Ph tablets
DO tablets
Secchi disc
Thermometer
Chart with turbidity, ph and do readings
2 vials
Find a location and keep track of the
coordinates
A huge net
Water

The
blue represents the second data collection. And the red represents the first
time of data collection.
Discussion: TURBIDITY OF 0.
D.O. OF 4PPM
Ph OF 7
Temperature OF 10 Degrees
Evaluation: Some things that could have affected
the experiment would have been location (how high or low down the stream/creek)
and time of day that the data was taken. Or maybe even the season. Speed of the
water. What the environment around the water is already. What the acidity in
the water already is. What human disturbances affected the water before testing.
Or if we didn’t kick around the organisms in the water.

I am assessing this lab write up.
ReplyDeletePlanning:
ReplyDeleteAspect 1- Not at all. I understand how you tried to incorporate the golf ball part of the lab in the research question, however I think you might have missed the purpose of the lab and what we were actually investigating. The goal was to find out the water quality of the stream by the chemical compounds, along with the presence or absence of macro-invertebrate pollution intolerance's. The hypothesis is also a bit off and hard to understand the reasoning.
Aspect 2- Not at all. The controls should explain what you controlled and how you controlled it. What was mentioned in the table for the controlled variables wasn't clear.
Aspect 3- Complete. The method for collection of data was expressed, it could have more details added.
Data collection and processing:
Aspect 1- Partial. Only the macro-invertebrate data was under data. Missing the golf ball data.
Aspect 2- Partial. There is missing data.
Aspect 3- Partial. The only graph shown is the macro-invertebrate graph.
Discussion, Evaluation, and Conclusion:
Aspect 1- Not at all. The only thing mentioned was the results for one of the streams. There was not clear reasoning or understanding of the results.
Aspect 2- Partial. you identified things that could skew the results. You did not include improvements and it is hard to understand.
Aspect 3- Not at all. There is no conclusion listed.
Comments: You are missing a lot of information needed to make this lab complete. I think you didn't fully understand what the purpose of the lab was. The introduction is a bit confusing and you should increase your references.
what are you talking about with a golf ball?? there wasn't anything that involved or stated something with the golf ball in it!
Deletenone left so im doing this one

ReplyDeletePlanning:
Aspect 1 - Complete, clear research question and hypothesis
Aspect 2 - Not at all, the controlled variables chart has the water conditions, not controlled variables
Aspect 3 - Partial, incomplete procedure
Data Collection and Processing:
Aspect 1 - Partial, not all data is present
Aspect 2 - Not at all, no processed data
Aspect 3 - Not at all, no graph or processed data
Discussion, Evaluation, and Conclusion:
Aspect 1 - Not at all, no discussion present
Aspect 2 - Partial, states weaknesses, but not how to fix them
Aspect 3 - Not at all, no conclusion present
Comments - Missing a lot of aspects needed to get a good grade. To go deeper in depth on the information you have present might help as well. The controlled variable chart is messed up, as I stated in the assessment. Also an arrow, circle, or something like that on the picture of the map would be good.
