Instructional Ideas
- Set up multiple isotopes in different colored balloons so students or groups that finish early can solve another problem for additional practice
Classroom Considerations
- Check the dates on the pennies used in the experiment before starting
- Relies on prior knowledge of atomic mass and solving systems of equations
Pros
- Connects math and science through a hands-on application
- Requires only basic materials
Cons
- None
