Natural Selection Simulation
Since the last class, you thought about what would happen to a species that changed over time and was then faced with a large scale change in its environment. Today, we will begin by discussing your thoughts.
On Friday, we will have an assessment regarding natural selection. Here are a few additional simulations that may help you out:
- Same habitats (for example, everyone with the "Polar Seas" habitat will gather to discuss). Your task is to evaluate each person's ideas and provide supporting or contradicting information.
- Present to the group
- Did any of your species survive?
- What would it take to survive? (What adaptations are needed for a species to survive?)
- For the organisms that did survive, what do you think would happen?
On Friday, we will have an assessment regarding natural selection. Here are a few additional simulations that may help you out:

Natural Selection
Today, we will continue working on the objectives from last class. To get started, please select the best possible choice to describe why dark colored mice appeared on the dark rock.
I believe that the mice became dark furred over time because:
a) the light colored mice changed to match the rock
b) ash from exploding volcanoes turned the mice dark
c) dark mice selected to migrate from sandy areas to the dark rock
d) on the rock the dark mice were favorably selected to continue their life cycle
Defend your choice!
We will get together to discuss the choices. Try to convince everyone that your choice is the best.
Voyage to Aquaterra - create the habitats
Exit notes
1. One thing that all of a sudden became clear to you.
2. One thing you want to make sure not to forget that you learned today.
3. One question you have about what was discussed today.
For next class, please read pages 17-25 in the Life Over Time book. Answer questions 3-5 on page 25.

What does it mean to be fit?
Objectives:
a) discuss what is meant by being evolutionary "fit".
b) explain how natural selection preserves favorable traits.
c) explain how variation, selection, and time fuel the process of evolution.
Language Objectives:
a) Watch a video and take notes based upon your key questions. Present this information to the class.
Opening skit: Survival of the Sneakiest
Investigating change of rock pocket mice in the Sonoran Desert of the southwestern United States.

1. One thing that all of a sudden became clear to you.
2. One thing you want to make sure not to forget that you learned today.
3. One thing that could be made better.
4. One thing you still have a question about.
For next class, please finish the graph and questions associated with today's activities.
