The teacher resource is a guide for educators that contains: 

• a general overview of how to use annotated papers in the classroom

• an overview of the topics and research covered in the article

• discussion questions for student engagement (by curriculum standards)

• links to related multimedia resources from HHMI|BioInteractive 

To explore mass extinctions, including the end of the dinosaurs, we highly recommend HHMI's free eBook Mass Extinctions: Lessons from the Past. It includes interactive graphics, animations, and videos, designed to examine the evidence and causes of mass extinctions and what we can learn about how humans are affecting the planet.
