Evolution: The Beak of the Finch

After an eventful start to the day in which we briefly lost power at our school and our digital classroom wall clocks are hours off, we decided to start the class period with Jack Horner’s entertaining TED Talk in which he describes his research connecting dinosaurs and chickens.

After the video, we returned to our discussion of Darwin’s finches from yesterday’s lesson.  Students watched the HHMI video The Beak of the Finch (below) and then set to work on the accompanying worksheet packet.  We will continue our work tomorrow during the short Friday class period.  Students who finish early are encouraged to try the Finch Song Activity on the HHMI website.

Evolution: The Beak of the Finch – Day 1

After some great discussion around evolution, pseudogenes, and the reactivation of the gene encoding teeth in chickens, we started off the lesson with a TED Talk from Jack Horner: Building a dinosaur from a chicken.  Students engaged in a spirited debate about the ethical considerations around tinkering with genetics.  We then transitioned to the HHMI Biointeractive video: The Beak of the Finch.  Students received a copy of the student quiz to work on in class and to either take home and complete as homework (for students taking the AP History exam tomorrow) or to complete in class tomorrow.
