I so hope you'll learn about isotopes. Watch a video to understand that isotopes of an element have the same number of protons but different numbers of neutrons. Then solidify the knowledge by examining examples of hydrogen, carbon, and oxygen isotopes.

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
