Scientific Method Exercise
Identify a situation in which you applied the scientific approach to solving a problem. Share your thinking! The problem you choose to write about can be very simple, such as: my flashlight won't work, or my car won't start, or I baked muffins and they were flat ( didn't rise properly) , or the toilet won't flush properly, or better yet, think of your own. These probably don't sound like "science" problems, but it is most likely that you would use the scientific method to solve them, without even realizing it. Avoid using people problems and child or pet behavior issues as your "problem." Follow these steps to create your first writing assignment:

1. Describe the situation and your observation,
2. Describe your hypothesis to explain the observation.
3. Describe your further observations or experiments to test the hypothesis. Be sure your hypothesis is one that can be tested. Consider what you might use for "controls".
4. Was the hypothesis correct? If not, can you find a better one? Or do you need a better experiment? If so, what would it be?

The assignment should be formatted as follows: Be sure to include the labels, so it is clear that you recognize and identify each step in the process.
Problem: (briefly describe your problem here)
Question: (This may be a "how" or "why" question that you will formulate a tentative answer to. Your tentative answer is your hypothesis.)
Hypothesis: (State the answer to your question above. This is your "best guess" regarding the answer to the question.)
Prediction: (This describes your experiment very briefly and states the outcome you expect that would support your hypothesis)
Experiment: (Describe how you tested your hypothesis)
Results: (Describe what happened, and whether the results supported or failed to support your hypothesis)

A group of 11 mice was given water, and another group of 10 micewas supplied with diluted black coffee (coffee:water 1:1) asdrinking fluids for five weeks. The composition of the diets andliving conditions were similar for both groups of mice. Bloodglucose was monitored weekly for all mice. After five weeks, therewas no change in average body weight between groups. Resultsindicated that blood glucose concentrations increased significantlyin the mice that drank water compared with those that were suppliedwith coffee. Finally, blood glucose concentration in the coffeegroup exhibited a 30 percent decrease compared with that in thewater group.

1. What was hypothesis of this experiment? What question(s) was(were) the investigator asking?

2. Which is the control group? Why?

3. Which is the treatment group? Why?

4. Did the researchers follow the scientific method in theirexperimental design? Explain.

5. Do you think that there may be any possible biases or otherproblems in this experiment? Explain.

6. Based on the data, was the hypothesis supported, and what canyou conclude from this experiment?

Several studies suggest that breast-fed babies become more intelligent children than formula-fed babies. One such study (Mortensen, Michaelsen, Sanders & Reinisch, 2002) involved a sample of over 3,000 women and men born in Copenhagen, Denmark, between October 1959 and December 1961. The samples were divided into five categories based on duration of breast-feeding, as assessed by physician interview with mothers at a one-year examination. The childâs intelligence was assessed using the Wechsler Adult Intelligence Scale (WAIS) at a mean age of 27.2 years. The results showed that duration of breast-feeding was associated with significantly higher scores on the verbal, performance, and full scale WAIS IAs. This difference was observed even after the researchers adjusted for differences in the social class and maternal education of the two groups. (This adjustment allowed the researchers to rule out any preexisting differences in the groups that might have independently contributed to IQ differences in their children. The authors acknowledged that other differences between the groups, such as the childrenâs genetic potential or their parentsâ caregiving skills or motivation to nurture, could explain the results. However, they believe that human milk contains various hormones and other factors that enhance brain growth and maturation.

1. State the research hypothesis in your own words. Identify the independent and dependent variables, and define all important concepts and terms as they are used in this study.

2. What evidence do the researchers offer as a test of their hypothesis? Is this evidence empirical (observable)? Is it valid?

3. What explanation do the researchers offer for their findings? Does this explanation make sense based on the evidence?

4. Given the results of this study, why canât the researchers draw a causal connection between type of food and later intelligence? What might be an alternative explanation for the results of this study? What could the researchers do in order to make a causal connection between the dependent and independent variables?

5. Are there any practical implications for this research?
