Natural Selection Lab Report
Instructions: As you complete each slide of the Natural Selection Virtual Lab Activity, please fill in this lab report with the appropriate information and data.

Title:
Include your name, instructor’s name, and the name of the lab

Objective(s):
What is the purpose of the lab

Hypotheses:
Include the if/then statement you developed during the virtual lab.

Variables:

Materials:
1. The Natural Selection Virtual Lab Activity
2. Natural Selection Lab Report

Procedures:
The procedures are listed in Natural Selection Virtual Lab Activity. You do not need to include them here.

Data Analysis:

Part 1: In your data tables you recorded the percentage of the rate of survival for both the white and brown rabbit in both the light-colored and the dark-colored environments.

Part 2: Using your percentages in part 1, create a graph that represents the rate of survival for the white and brown rabbits in each type of environment.

Insert chart [Hint: don’t forget to consider the relationship between your data and the type of graph to best represent your data. A bar graph would be the best option to analyze this data.]

Conclusion:
Be sure to answer the following reflection questions as a summary in the conclusion of your lab report:
1. Were your hypotheses correct or incorrect? Why or why not?
2. Using Table 1, which color rabbit had the higher rate of survival in the light-colored (white) environment? Explain why this occurred.
3. Using Table 2, which color rabbit had the higher rate of survival in the dark-colored (brown) environment? Explain why this occurred.

Questions
Using what you have learned from the lesson and the virtual lab activity, answer the following questions in complete sentences.
1. How did the colors of each type of prey affect its population size over time?
2. What color rabbit seemed to camouflage the best in this snow habitat and why? What color rabbit seemed to camouflage the best in the summer habitat and why?
3. How do you predict the data would change if you continued? Explain your answer.
4. What traits could help a predator be more “fit” to survive in each environment?
5. Describe other adaptations besides color that could affect an individual’s survival.
6. Explain what will happen if there are not enough resources to support the individuals in a species.
