Objectives:
Students will use a multimedia simulation to explore the effects of natural selection on a larkey population.

Students will explain that natural selection is the process by which the individuals best adapted to their environment tend to survive, reproduce, and pass on their traits.

Plans:

Sponge: What might happen to a population of spotted and striped larkeys if they had to move to a prairie?

Anticipatory Set: Review sponge and selected problems from “Bikini Bottom Genetics 2” (ho...

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 th...

Objective: Students will explain how the traits expressed by members of a population can change naturally over time.

Sponge: Two long-haired dogs (dad: Ll, mom: LL) reproduce and have puppies.  Use a Punnett square to show the possibility of them having long or short-haired puppies.

Anticipatory Set: Complete “Response Sheet: Natural Selection;” using Think-Ink-Pair-Share

After partner share, discuss as a class & share ideas

Guided Practice: Read “Successful Variations” (Daybook ...

Objectives:
Students will use a game simulation to experience change in a population due to selective pressure.

Students will explain how environmental factors put selective pressure on populations.

Sponge: Using a Punnett square, calculate the possibility of a normal heterozygous (Bb) mouse and a blind (bb) mouse having blind mice as offspring.

Anticipatory Set:
-Review sponge and genetics vocabulary – return the genetics quiz, give them opportunity to correct quiz and earn back points
-Q: What...
