Susquehanna River Lab Report
On the trip with SWEEP the health of the Susquehanna River was studied. In order to do that, chemical test, biological tests, and physical observations were made. Chemical testing showed the more scientific side of water quality, such as the amount of nitrates, phosphates, the pH values, temperature, dissolved oxygen, and turbidity. Searching for macroinvertebrates was the biological testing. Certain macroinvertebrates and the quantity found determines how healthy the stream is. Physical observations such as observing the grasses, the rapids, and looking for birds nearby can also indicate good water quality. It is important to test the health of the river because the Susquehanna greatly affects all of those who live near it. All of the tests done show that the quality of the Susquehanna river is overall very healthy. …show more content…
Some include, chemical testing, biological tests, and physical observations. Chemical testing consists of testing for the amount of nitrates, phosphates, the pH values, temperature, dissolved oxygen, and turbidity. These aspects of the river were all tested because they can show how healthy the river is. Testing these aspects is very simple but requires a tool kit. After the testing is done, in order to determine how healthy the river actually is, tests can be done to show the levels of chemicals, water clarity, the temperature and more. Nitrates should be greater than or equal to one parts per million (ppm), phosphates should be less than or equal to .1 ppm, and the pH values should be about equal to seven. The dissolved oxygen in the river depends on the temperature, if the temperature is cooler than the dissolved oxygen levels will be higher, but the recommended amount of dissolved oxygen should be greater than or equal to five. For a healthy river the turbidity levels should be 120 centimeters
Salt Creek And Barker Lake Lab Report
566 Words | 3 PagesIn this lab we were trying to figure out if Salt Creek and Barker Lake had the correct chemical balances to sustain catfish for the years coming. In order to find this out, we tested the water using a Hach Water Testing Kit. Inside were dissolved oxygen reagent powder pillows 1, 2 and 3 which we added and mixed into our sample water to prepare it for testing. Then we added droplets of Sodium Thiosulphate Solution into the prepared water too see how much dissolved oxygen parts per million were in the water. Our independent variable in this experiment was the 5 different testing sites that we went to for water samples.
Conodoguinet Creek Field Observation Report
842 Words | 4 PagesOn October 8th, 2015 our class took a field trip to the Conodoguinet Creek to test the water quality. We did 3 experiments to help us conclude the quality. During the first experiment we observed the different types of organisms in the creek. We also took tests for eutrophication in the water. Another experiment we performed were acidity tests.
Skittlefish Lab Report
598 Words | 3 PagesNatural Selection is the concept that organisms better adapted to their environment tend to survive and produce more offspring. This leads to the creation of populations and diversity of life within them. In the Skittlefish Lab, many separate occurrences can be observed which detail and explain how Natural Selection works on a population over a period of time. Certain adaptations in a species in its entirety may display how individuals impact the whole population as they pass their traits onto their offspring, which do the same. This lab required students to observe the individual “Skittlefish” and “Sea M&Ms” in different environments as they camouflaged and hid from predators.

Potomac River Environmental Problems
371 Words | 2 PagesRivers, specifically, the potomac river is main water systems that I have chosen to report. The potomac river surrounds multiple states including Virginia, Washington D.C. and Maryland is one of the largest rivers in the eastern coast of the United States. A report from the nonprofit advocacy group American Rivers, noted what locals have said for years: “that urban development is funneling tons of polluted rainwater to the river, that chemical fertilizer and manure from farms make matters worse, and that wastewater overflowing from sewers, along with pharmaceuticals flushed down toilets, contribute to dead zones in which marine life dies and might cause fish to switch sexes. Some male fish in the river mysteriously have eggs.”
Penny Lab Report
463 Words | 2 PagesThe purpose of this lab was to change pennies from copper to silver to gold, like alchemists have attempted to do in history. Through the data and observations gathered throughout this experiment, it can be concluded that the pennies were not changed into a different element. For example, the density of the penny from 2005; which was the penny that was experimented on to see whether or not it could turn into silver; was 4.62 g/cm3 before the experiment and 4.89 g/cm3 by the end of the experiment. If this copper penny really would have turned into silver, then the density of the penny would be 10.49 g/cm3; which is the density of silver; by the end of the experiment. The penny may have turned silver in color, but this was only because it was plated in the zinc that was added to the beaker of water in the experiment.

Cullowhee Creek Essay
466 Words | 2 PagesWe took a large net and set it vertically in the water, and then somebody got in the creek and kicked up sediment into the net. After doing this a few times, we collected all of the creatures off of the net and into an ice cube tray. We then examined the creatures and noted the variety (or lack thereof) of the creatures. The larger the variety in the species of the creek, the healthier the creek is. We noticed several species of fly larvae such as stone fly larvae and caddis fly larvae. We also noted a few worms.
