Hypotheses:

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


Variables:


Materials:


The Natural Selection Virtual Lab Activity

Natural Selection Virtual 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 in the conclusion of your lab report:


Were your hypotheses correct or incorrect? Why or why not?

Using Table 1, which color rabbit had the higher rate of survival in the light-colored (white) environment? Explain why this occurred.

Using Table 2, which color rabbit had the higher rate of survival in the dark-colored (brown) environment? Explain why this occurred.

What color rabbit seemed to camouflage the best in this snow habitat, and why?

Questions:

Using what you have learned from the lesson and the virtual lab activity, answer the following questions in complete sentences.


How did the colors of each type of prey affect its population size over time?

How do you predict the data would change if you continued? Explain your answer.

What traits could help a predator be more "fit" to survive in each environment? Be specific.

Describe other adaptations besides color that could affect an individual's survival.

Explain what will happen if there are not enough resources to support the individuals in a species.

This experiment tested natural selection. What could be another possible mechanism of evolution for the rabbits to evolve? Be specific.

Answer:

The procedures are listed in your virtual lab. You do not need to repeat them here. Please be sure to identify the test variable (independent variable) and the outcome variable (dependent variable) for this investigation.

Reminder: The test variable is the item that is changing in this investigation. The outcome variable is the item that you are measuring in this investigation.

Test variable (independent variable):

Outcome variable (dependent variable):

Data

You will investigate both environments. Record your data for each trial of that environment in the data charts below.

Conclusion

Your conclusion will include a summary of the lab results and an interpretation of the results. Please write in complete sentences.

1. What caused the tree bark to become darker?

What caused the tree bark to be darker is the day the darker the day is the darker the tree bark gets.

2. In the lab simulation, which color peppered moth was able to have the higher rate of survival on the light bark?

The light peppered moth had a higher rate of survival on the light bark.

3. In the lab simulation, which color peppered moth was able to have the highest rate of survival on the dark bark?

The dark peppered moth had a higher rate o survival then the light peppered moth on a dark bark.

4. During the Industrial Revolution, explain what caused the population of light-colored peppered moths to decrease and the population of dark-colored peppered moths to increase over time. Be sure to include how the ability to survive and reproduce impacts the process of natural selection.

The trees were also darkened as a result and the light-bodies moths that were able to blend with the light-coloured lichens and tree barks were in danger due to their predation by the birds. This shows to the rapid decrease of the light-coloured moths.

5. Predict which color peppered moth would have a better chance of survival in your neighborhood? Explain why.

I think the dark peppered moth had more chance to survive in my neighbourhood because its a lot of times dark and faster here because we are more in the north.
