Your Mission: You are studying populations of goldfish that live in ponds in a park where visitors can feed them. You are interested in what determines goldfish population size in each pond. You hypothesize that ponds receiving more food from visitors have more fish in them. You decide to do a study to test whether population sizes of goldfish are larger when they have more food. Approach 3. Using 2-3 full sentences, describe an observational or experimental study that you would do to test this hypothesis, making clear how your study is based on the cause and effect that you have just described. [1 pt] 4. Did you describe an observational or an experimental study? [1 pt] 5. Why did you choose that approach? (explain in 1-2 sentences that refer to pros or cons that we have discussed about these approaches) [1 pt] 6. Based on the study you described above, what will be your independent variable? [1 pt] 7. What will be your dependent variable? [1 pt] 8. What will be your unit of replication? [1 pt] Prediction 9. State a prediction for what the results of your study would look like if they support the hypothesis given in the Mission. (1 sentence) [1 pt] 10. Make a figure of results that would be consistent with that prediction: 1. Label y axis with the variable that should be on the y [1 pt] 2. Label x axis with the variable that should be on the x [1 pt] 3. Draw results bars or lines consistent with your prediction [2 pts] Discussion Question(s)/ Follow-Up [3 pts] 11. You measure the abundance of goldfish in one of your ponds in one year and there are 50 individuals there. You go back the next year and there are 100 individuals. Using the geometric equation, what is the growth rate of the population and how many individuals do you predict you will see if you come back again for a third time? Show your work.
