Activity for The Day the Mesozoic Died
Description
This activity explores the research described in the short film The Day the Mesozoic Died. The film traces the uncovering of key clues revealing that an asteroid struck Earth 66 million years ago, triggering a mass extinction.
The Day the Mesozoic Died and this supporting activity can be used in several science classes, as it presents a stellar example of many different disciplines (geology, physics, biology, chemistry, and paleontology) contributing to a compelling hypothesis.
The “Student Handout” probes students’ understanding of the key concepts addressed in the film. The “Educator Materials” document provides suggested pause points in the film with questions for students, background information, and detailed discussion points; a list of related resources and references; and an answer key for the “Student Handout.”
