Instructional Ideas
- Use the video to introduce isotopes
- Have learners draw atomic models of some of the examples to compare/contrast isotopes
Classroom Considerations
- Viewers should already be familiar with basic atomic structure
- This video is hosted on YouTube
Pros
- Video connects isotopes to other content, such as using C-14 for dating and using O-18/O-16 ratios to estimate paleotemperatures
Cons
- Speaker does not reference half of the examples shown on the video screen
