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 examine concepts about the evolution of human bipedality explored in the short film Great Transitions: The Origin of Humans. They create their own trackway of footprints and compare it to a trackway of fossil footprints.
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 challenges students to identify observations that Darwin and Wallace made during their travels, as shown in the short film The Origin of Species: The Making of a Theory. Students then evaluate claims about evolution by natural selection based on these observations.
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.
This activity supports concepts covered in the short filmThe Day the Mesozoic Died by replicating observations and measurements made by researchers of fossilized protists, called foraminifera (or forams), below and above the K-T boundary.
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.
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.
