Weighing the Evidence for a Mass Extinction: On Land

This activity supports concepts covered in the short film The Day the Mesozoic Died. Students analyze graphs and data on pollen grains and fern spores to form a picture of the living landscape before and after the mass extinction that marked the end of the age of the dinosaurs.

Determining the Size and Energy of the K-T Asteroid

This activity allows students to calculate the mass, size, and kinetic energy of an asteroid that struck Earth 66 million years ago, based on the total abundance of iridium in a sediment layer. It supports concepts presented in the short film The Day the Mesozoic Died.

Chemical Signatures of Asteroid Impacts

This activity allows students to analyze the chemical data that led researchers to conclude that a layer of clay at the boundary between the Cretaceous and Paleogene rock layers (the K-Pg boundary) contained an extraordinary concentration of iridium. It supports concepts presented in the short film The Day the Mesozoic Died.

Calculating Iridium Fallout From an Asteroid Impact

This activity allows students to calculate how much iridium was released, and eventually deposited all over the Earth, by the impact of an asteroid that struck Earth 66 million years ago. It supports concepts presented in the short film The Day the Mesozoic Died.
