Zebrafish have become a model organism in many areas of research and are now being used with more frequency in the classroom to teach important biological concepts. The two guided inquiry exercises in this article are each aimed at a different level of instruction, but each can be modified to fit the needs of many high school or college-level courses. The "Zebrafish Development and Environment'' exercise teaches high school students about zebrafish development by presenting a series of embryos at different ages. Without access to visual references, students are asked to rank developing zebrafish by age and explain their choices. The students also learn about the heart and circulatory system and the effects of temperature on physiological processes. The second exercise, "Oxygen Consumption,'' is a 2-week laboratory designed for introductory college biology majors and involves the concept of oxygen consumption as a predictor of metabolic rate. During the first week of lab, students are introduced to the concept and learn how to measure oxygen consumption in zebrafish. In the second week, they perform an instructor-approved experiment of their own design, analyze the results using statistics, and write a report.
