‘But, Is It Supposed to be a Straight Line?’ Scaffolding Students’ Experiences with Pressure Sensors and Material Resistance in a High School Biology Classroom
This case study examines how material resistance (limitations posed by the physical world) and graph interpretation intersected during a high school biology investigation using digital sensors. We use an extended episode from a small group to illustrate how, in an inquiry-based unit, measuring near the resolution limit of a sensor caused scaling issues in graphs.
