Instructional Ideas
- Have the class read an article about the microbes living inside termites, then show the video
- Plan discussion time after the video to talk about the multiple lines of evidence scientists have that support endosymbiotic theory
Classroom Considerations
- Compare and contrast mitochondria and chloroplasts with middle schoolers before viewing to make sure they understand the functions of both
- This video is hosted on YouTube
Pros
- The narrator does a fantastic job of presenting the theory and evolutionary lines associated with it
- Diagrams help clarify some of the more difficult aspects of the content
Cons
- None
