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 develop arguments for the adaptation and natural selection of Darwin’s finches, based on evidence presented in the film The Beak of the Finch.
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.
