This purpose of this lesson is to enhance students' understanding of the research question that is really being addressed by experiments, observational studies and research. Through the use of a very simple question about which brand of soda that students prefer, the discussion allows the teacher and students to dig deeper into the idea that what you think a study is asking may not really be what is being found. Students will actually do an experiment, observational study and survey with only a superficial examination of the research question. (They are doing a quick TASTE TEST.) It is only after the activity that the students will try to decide precisely what they were researching and to whom this study can be generalized.
