Objectives:
Students will record and process information presented in a video about natural selection.

Students will explain how natural selection resulted in the biodiversity of the Galapagos Islands.

Plans:

Sponge: If limiting factors are removed, what will happen to the size of a population?

Anticipatory Set: Review sponge and key facts from yesterday’s viewing of film

Guided Practice:
DEFINE “natural selection” with steps recorded (the process wherein individuals with adaptations that help withstand selective pressure will survive and reproduce)

Independent Practice: Finish viewing film and complete the video questions

Making Meaning:
-Q: Considering where the Galapagos Islands are, how did land and plant animals first get there?
-Q: Why do the Galapagos have such a high number of plants and animals that are found no place else on Earth?
-Q: Why do so many of the islands have finches that are unique to that island?
-Q: How do invasive species get to the Galapagos these days?
-Q: How do new populations affect established ecosystems?

Closure: How are Darwin’s finches an example of natural selection?

Homework: "Bikini Bottom Genetics 2" due tomorrow (Friday 12/03)
