The content objective for this activity ranges from a deeper understanding of rates of change (slope) and functions with middle-level students, to a real life exploration into non-differentialble points and why limits DNE for calculus students. In both cases, the activity stays the same, but the follow up questions change.
- Students predict what motion would be required to create a variety of graphs.
- Students challenge their prediction by creating the graphs of their motion with a CBR motion detector connected to a TI-84 + calculator.
- Students take what they learned, and repeat steps 1 and 2 for all graphs.
- Discuss impossible graph components (vertical lines, cusps, corners), discuss limits of the slope (velocity) and how that connects to calculus, physics, and our every day life.
