Natural Selection and the Evolution of Darwin's Finches
Read the Fine Print
Rating
0.0 stars

This lesson supports viewing of the short film The Beak of the Finch. Students watch segments of the film and then engage in discussion, make predictions, create mathematical models of data, and use multiple sources and types of evidence to develop arguments for the evolution of Darwin’s finches.

Natural Selection in an Outbreak - Ebola: Disease Detectives
Read the Fine Print
Rating
0.0 stars

In this lesson, students will analyze Ebola sequences that were obtained from patients in Sierra Leone during the 2013–2016 outbreak in West Africa. Students are challenged to place sequences into groups based on similarities to determine the transmission history of the virus. Students then compare their results to those of scientists at the Broad Institute of MIT and Harvard, who followed a similar procedure at the beginning of the outbreak. This lesson is meant to be used in conjunction with the video: "Natural Selection in an Outbreak."
