Instructional Ideas
- Use different sizes of springs to calculate multiple k values
Classroom Considerations
- The activity requires several pieces of equipment to measure the stretch on the springs
- Individuals should be able to find the slope of a line given two points
Pros
- Provides a sample data collection table for the groups to use
- Includes a post-activity assessment to connect the activity to engineering practices
Cons
- None
