SCI Wk 1 Lab Reporting Form Essay

Answer = The graph demonstrates that as the dissolved oxygen levels increase the fish population will increase. The fish show strong growth from 6ppm to 12ppm dissolved oxygen. As the levels reach 14ppm to 18ppm the have a repeating effect as 6ppm to 12ppm.. With this being said, it shows that fish will show growth progress to a certain level of dissolved oxygen and then level off.

1. Record your hypothesis about what will happen when Biuret solution is mixed with the solutions from test tubes 1, 2, 3, and 4 here. Be sure to use scientific reasoning to support your hypothesis.

1. Use the graph below to predict what the results will look like if the null hypothesis is

6. Although you are basically satisfied with the analysis thus far, you are concerned about the

Explain how the ecosystem was affected by the missing species for each round of the demonstration.

What participant behavior was being measured? (DV)(.5 pts) Specifically state how the data were collected and then state how they were summarized. You will probably need to get this information from the graph.

11. For each of the following, indicate whether you would use a pie, line, or bar chart, and why.

Based on the results of your experiment, would you reject or accept each hypothesis that you produced in question 1? Explain how you determined this.

a. It is a different species than any of the other species you have identified

6. Restate your predictions that were correct and give the data from your experiment that supports them. Restate your predictions

- To test this hypothesis my experimental approach would be testing different bodies of water or testing one and just testing different areas while tracking the fish.

7. Graph the data from Table 1: Water Quality vs. Fish Population (found at the beginning of this exercise). You may use Excel, then “Insert” the graph, or use another drawing program. You may also draw it neatly by hand and scan your drawing. If you choose this option, you must insert the scanned jpg image here.

The lines would start by going up until it gets to 12 then would begin to bounce around from increase to decrease.

5) Graph the equation you wrote in step four superimposed over the original data. Comment on how well or how poorly the equation fits the data.

a) Graph the following data on semi-log OR regular graph paper. Determine the D-value using the graph. Show your work.
