The task asks students to use their understanding of analyzing and interpreting data, constructing explanations, and ideas about what happens when objects collide to make sense of an investigation conducted by a [fictional] student named Sam about why it is so important to wear helmets when bike riding. Throughout the task, students are asked to consider aspects of Sam’s experimental design, collected data, and conclusions as a mechanism to elicit students’ sense-making. This task is intended to be used as an assessment of student understanding of an unpacked "part" of a performance expectation (the learning performance described). This task was developed by the team at CREATE for STEM at Michigan State University.
