Tracing the Scientific Method 1.
While the hypothesis is never explicitly stated, it is safe to assume that the researchers’ hypothesis is that coffee does in fact, prevent the development of high blood sugar. The question used to form this hypothesis was, does the ingestion of coffee prevent the development of hyperglycemia in mice? 2. The control group in this study would be the 11 mice that were given the water. They would be considered the control group because nothing changed for them in terms of their diet or what they drank (water), their conditions were what the other mice were tested against. 3. The treatment group in this study would be the 10 mice that were given the diluted black coffee. They would be considered the treatment group because their condition was manipulated to get results that could be different from the control group. 4. The researchers did follow the scientific method in their experimental design because they followed each step with care. They asked a question (Does the ingestion of coffee prevent the development of hyperglycemia in mice?), and set out to find the answer to the question, even though other researchers had conducted experiments similar to this one. They did background research on the mice and their condition (having a gene that mutates which causes diabetes) and then shaped the format for how they would test their question out. Although I don’t recall them explicitly stating their hypothesis, again, it is safe to assume that the researchers’ hypothesis was that coffee does prevent the development of high blood sugar. The researchers then tested their hypothesis with an experiment with strict care and detail. From the results gathered from the experiment (the treatment group’s blood glucose levels dropping 30% and the control group’s increasing) they determined their hypothesis to be true. And the results were published in a scientific journal. 5. It is hard to tell...
