The video focuses on geologic clues that led to acceptance of the theory that an asteroid impact killed of the dinosaurs. I ordered the video and plan to use it after my students learn how geologists interpret rock layers (superposition, cross-cutting, inclusions, etc.)
The HHMI site also provides several classroom ready resources to complement the video, including a quiz, as well as teacher guidelines and student handouts for several activities. To access those, CLICK HERE.
