Unit 8: Natural Selection
Chapter 1: Environmental Change and Trait Distribution
Lesson 1.4: Investigating changes in trait distribution

Goal:
·  Observe why the distribution of fur traits changes over time.

Do:
Open the Natural Selection Simulation and open the mode: Fur and Temperature A.
Change the temperature of the environment to cold (Level 1) by moving the    Temperature slider.
Press RUN and observe the population for at least 50 generations.
Press ANALYZE and compare starting and ending histograms.

Tips:
·  Press the Reset button and repeat your test to see if you observe the same changes each time.

Reading: Wildlife in the Woods
First, read and annotate the “Common Garter Snake” article.
Next, choose one other article to read and annotate.
Then, answer the reflection questions that go with the three articles you read.

What part of the environment might make an individual more or less likely to survive?

Which traits does the common garter snake have that might be adaptive for the environment where it lives?

Observe and record how the number of snake strips changes over time.

What part of the environment might make an individual more or less likely to survive?

Which traits might be adaptive for that environment?

Observe and record how the adaptive trait changes over time.

Article 3
