Define the Problem: If you were a doctor trying to measure a patient’s respiratory fitness, what methods could you use to find this out? With your groups, design a way to measure lung capacity (a measure of respiratory fitness).
Activity Embedded Assessment
Research & Investigation: Have students record their hypotheses, methods, observations, and conclusions for the investigation.
Designing a way to measure Lung Capacity: Using the results of their experiment, students should:
- First, brainstorm potential pitfalls of their experimental design. Would these ‘errors’ in experimental design over or underestimate lung capacity? Discuss with your group members.
- After brainstorming ideas, if you were to repeat the experiment again, how would you avoid experimental errors? Why do you think different individuals in the room had different lung capacities?
