Synopsis:  This investigation is divided into two parts.  In Part 1, students work in Epi Teams to select their own hypotheses and design and conduct an in-class observational study.  Students create questions that will allow them to count and classify their "exposure" and "outcome," assure that participants have given their informed consent, collect data, display data in a 2x2 table, calculate risks and a relative risk, and make inferences.  In Part 2, each Epi Team presents their study results to the class, according to the IMRAD format (Introduction, Methods, Results, and Discussion).
