This activity builds on information presented in the video Selection for Tuskless Elephants. Students use scientific evidence and reasoning to construct an explanation of and develop an argument for tusklessness in elephant populations.

In this activity, students collect and analyze evidence for each of the major conditions for evolution by natural selection to develop an explanation for how populations change over time.

In this activity, students evaluate and discuss statements about the evolutionary relationship between birds and dinosaurs covered in the short film Great Transitions: The Origin of Birds.

This activity supports concepts covered in the film The Making of a Theory. Students develop their nonfiction reading comprehension by analyzing excerpts from texts written by Charles Darwin and Alfred Russel Wallace.

This activity supports the viewing of the film The Making of a Theory. Students evaluate and discuss several claims relating to the history and evidence that led to the theory of evolution by natural selection.

In this activity, students identify and explain the evidence presented in the short film The Day the Mesozoic Died that led to the discovery that an asteroid struck Earth about 66 million years ago, causing a mass extinction.

In this activity, students evaluate and discuss statements about the evolutionary relationship between milk consumption and lactose tolerance discussed in the short film Making of the Fittest: Got Lactase? The Co-evolution of Genes and Culture.

This lesson supports concepts covered in the film The Birth and Death of Genes. After watching the film and reading a couple of scientific passages, students explain how understanding about icefish adaptations might help develop treatments for health conditions.
