Introduction to Science

The Scientific Method

Dissolved oxygen is oxygen that is trapped in a fluid, such as water. Since many living organism requires oxygen to survive, it is a necessary component of water systems such as streams, lakes and rivers in order to support aquatic life. The dissolved oxygen is measured in units of parts per million (ppm). Examine the data in Table 4 showing the amount of dissolved oxygen present and the number of fish observed in the body of water the sample was taken from; finally, answer the questions below.

Dissolved Oxygen (ppm)	0	2	4	6	8	10	12	14	16	18
Number of Fish Observed	0	1	3	10	12	13	15	10	12	13

QUESTIONS

1. Make an observation - Based on the data in Table 4, discuss what patterns you observe in regards to dissolved oxygen content and fish populations in the body of water?

2. Do background research - Utilizing at least one scholarly source, describe how the dissolved oxygen content in a body of water can effect fish populations.

3. Construct a hypothesis - Based on your observation in question 1 and your background research in question 2, develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water?

4. Test with an experiment - Describe an experiment that would allow you to test your hypothesis from question 3. This description must provide ample detail to show knowledge of experimental design and should list the independent and dependent variables, as well as your control.

5. Analyze results - Assume that your experiment produces results identical to those seen in Table 4, what type of graph would be appropriate for displaying the data and why?

6. Analyze results - Graph the data from Table 4 and describe what your graph looks like (you do not have to submit a picture of the actual graph!).

7. Draw conclusions - Interpret the data from the graph made in Question 7. What conclusions can you make based on the results of this graph?

8. Draw conclusions - Assuming that your experiment produced results identical to those seen in Table 4, would you reject or accept the hypothesis that you produced in question 3? Explain how you determined this.
