Conodoguinet Creek Lab Report

This week we went to the Conodoguinet Creek. While we were at the creek we did many different things. One of the experiments we did was the Critter Count which was my favorite. Another experiment we did was the Eutrophication Tests. The last Experiment we did was the bobber test. We were gonna do another experiment, the Acidity Test but we didn't get to. We do have the results from the Acidity test from another time.

We found many different critters in our group. Some of them were big and small and they were all different. We found the critters by lifting up rocks and finding and counting the number of critters on and under the rocks. We found many group 1 critters. The critters in group one are the ones that are pollution sensitive. We

Our group found a total of 3 critters in group 3. Throughout this experiment we found many different types of critters. Some of the critters we found are Gilled Snails, Stonefly, Water Penny, Scud, Crayfish, Pouch Snails, and many more. Since the creek is not polluted, many critters can thrive there. Another experiment we did was the Eutrophication test. The Eutrophication test determines the amount of nutrients there are in a stream, creek, or most bodies of water. When we did the Eutrophication test we got a lot of low numbers. For the Phosphate test they were mostly a 0 with a .1. When we did the nitrate test we got .25, .75, 1, 1.2, 1.5, 1.3, and a .9. for the dissolved oxygen tests they were all mostly high results. Some of our results for the Dissolved Oxygen tests were 12, 11, 8, and 7. Those were the results of our teams Eutrophication

The last test was called the Acidity test. The Acidity test gives us the alkalinity and acid of a stream. On the Ph scale it goes from 0 to 14. A stream with a great abundance of life will probably have a reading of 7 on the scale( which is near neutral). Here are the results from some of the tests. The ph paper scales were all 7 which is pretty good. The Alkalinity tests were fairly interesting as well. The Alkalinity tests read that section P’s reading was 12, section A’s reading was 14, section w’s reading was 12. That whole groups average was about a 13. The groups found the number of rocks that neutralized acid. Section p found that 24 rocks neutralized acid. Section a found that 19 rocks neutralized acid. Section w found that 22 rocks neutralized acid. The overall average for the number of rocks that neutralized acid was 21. The groups also found the number of rocks that did not neutralize acid. Section p found that 8 rocks did not neutralize acid. Section a found that 7 rocks did not neutralize acid. Section w found that 14 rocks did not neutralize acid. The overall average for the number of rocks that did not neutralize acid was 29 rocks. We also found the percentage of rocks that neutralized acid. Section p found that 75% percent of their rocks neutralized acid. Section a found that 73.1% of their rocks neutralized acid. Section w found that 61.1% of their rocks neutralized acids. Those are the results
