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.
