A short article by Dr. Sean B. Carroll detailing the discoveries covered in the film The Day The Mesozoic Died.
A lesson in which students analyze the chemical data that led researchers to conclude that the K-T boundary layer contained an extraordinary concentration of iridium.
A lesson in which students read a passage and answer questions about the information presented, testing their non-fiction reading comprehension.
A worksheet in which students calculate how much iridium was released, and eventually deposited all over the Earth, by the impact of the asteroid that caused the K-T extinction.
A hands-on activity in which students see first-hand the difference in foraminifera fossils below and above the K-T boundary.
A worksheet in which students write down the evidence that led to the discovery that an asteroid struck Earth about 66 million years ago, causing a mass extinction.

A poster from the 2012 Holiday Lectures on Science, Changing Planet: Past, Present, Future. It details the importance of foraminifera, known as "forams" for short, in discovering significant changes in Earth's past.
A poster from the 2012 Holiday Lectures on Science, Changing Planet: Past, Present, Future. It illustrates how the Earth has evolved over the past 4.6 billion years, and highlights how that evolution influences biological evolution.
A lesson in which students analyze graphs and data on pollen grains and fern spores to form a picture of the living landscape before and after the K-T mass extinction.
This hands-on activity requires students to “visit” different K-T boundary sites.

This activity guides students through building a conceptual model of how carbon dioxide affects Earth's climate
This student worksheet highlights climate concepts in the EarthViewer app.
This activity supports the viewing of the film The Origin of Species: The Making of a Theory. Before and after watching the film, students discuss and evaluate several statements about Charles Darwin, Alfred Russel Wallace, and the specific evidence that led each of them to the theory...
This activity supports the HHMI short film The Origin of Species: The Making of a Theory. Students are presented with a map of the Malay Archipelago and some field notebooks with observations of animals. By plotting which animals are found on which island, the students discover the...
This article by Gorongosa National Project staff explains the project’s history, mission, and future goals.
The poster supporting the 2014 Holiday Lectures, Biodiversity in the Age of Humans, illustrates many ways that humans are affecting the earth.
