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)

choose two nonhuman species that interact with each other, such asbees and flowers, or predator and prey species, or two species thatcompete. Or, you can consider the effect of an environmental factoron living nonhuman organisms, such as the effects of light or soundon plants or animals, or how food preference, or nutrientquantity/quality affect plants or animals. These are just a fewexamples. Your observations may lead you to many other types ofquestions about living organisms, their interactions, andrequirements for life.

Start with an Introduction/Observation and move through the stepsof the scientific method as outlined below. Your paper shouldfollow this format.

Remember, you don't have to actually do the experiment, just writewhat you would do to test your hypothesis. The experiment youcreate to test your hypothesis should contain a control andtreatment group and be detailed enough that it could bereproducible by others.

Observations/Introduction:

Describe your observation.
Include background information about your observations that youhave found using references.
List and cite references using APA format.
Question: Ask a question about the observation that you havemade.

Hypothesis: Write a statement that describes your explanation forthe observation and question.

Prediction: What do you predict as outcomes (results) of thisexperiment? (An if-then statement)

Controlled Experiment and Methods:

Describe the experiment.
Describe variables to be held constant.
Note variable to be tested.
List controls.
Tells what data will be collected.
Describe how only one variable is being tested at a time, whileothers are held constant.
Results: Give the results (data) for the experiment. This will becreated (imagined) by you because you are not actually doing thisexperiment.

Conclusion/Discussion:

Do you reject or accept the hypothesis based on the results?
Discuss what this means in terms of the hypothesis, or need foradditional experiments, or perhaps practical use of the results.

Hypothesis I: The same histidine synthesis gene is defective in both strains B and C.

Hypothesis II: Different histidine synthesis genes are defective in strains B and C.

Results:

Strain

Growth on SD + HIS

In Question Set 4, two hypotheses were discussed regarding the HIS mutations in strains B and C. Do your SD plate and SD+HIS plate results support Hypothesis I or Hypothesis II from Question Set 4?

3. A. ) Keeping in mind your answer to question #2 above, what is the predicted genotype of the diploid arising from the BxC mating?

B. ) Can you explain your SD plate and SD+HIS plate results in regards to the URA and LEU genotype of the new diploid that you have made?
