Reflection: Complex Tasks Salmon Body Structures - A Fish Dissection - Section 2: Observations of External Anatomy


One of the most difficult tasks for students is counting the number of fins on the fish. Each year, when I teach this lesson, students groups give answers ranging from 5-10 fins. This year was no exception. I stress with my students that it is not important that they count the correct number of fins on their first attempt, merely that they use their observation skills and revise their thinking based on evidence shared by their peers. I have found that drawing a fish on the whiteboard, labeling each fin, and then having students idenitfy the fins helps students revise their thinking. I also display a fish using the document camera and have students idenitfy the fins on the fish specimen to help bridge the gap between the visual representation (my drawing) and the actual fish specimen.
