Objective(s)
In your own words, what was the purpose of this lab?
I believe the purpose of this lab is to see how much our society is evolving.
Hypothesis
In this section, please include the if/then statements you developed during your lab activity. These statements reflect your predicted outcomes for the investigations. You will investigate two different versions of the tree environment as it changes over time: light-colored bark and dark-colored bark. Be sure to list your hypothesis for each environment below.
Example: If I investigate the light-colored bark environment, then I will observe an increase in the light-colored peppered moths over time.
Hypothesis for the light-colored bark: There will be an increase in light-colored of light-colored moths and an decrease in dark-colored moths.
Hypothesis for the dark-colored bark: There will be an decrease in light-colored moths and an increase in dark-colored moths.
Procedure
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): The test variable is the colored bark
Outcome variable (dependent variable): The outcome variable is the colored moths population
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.
What caused the tree bark to become darker?
What caused the tree bark to become darker is the time of the day the darker it is the darker the bark is.
In the lab simulation, which color peppered moth was able to have the higher rate of survival on the light bark?
The light-colored moth had a higher rate of survival than the dark-colored moth.
In the lab simulation, which color peppered moth was able to have the highest rate of survival on the dark bark?
The dark-colored peppered moth had a higher rate of survival than the light-colored moths.
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.
What caused the population of light-colored moths to decrease and the population of dark-colored moths to increase over time was because the dark-colored moths could camouflage themselves on the dark bark trees and the light-colored moths couldn’t protect themselves from predators because they had no where to hid.
Predict which color peppered moth would have a better chance of survival in your neighborhood? Explain why.
I believe that the dark-colored peppered moth would have a better chance of survival than the light-colored moths because there is mainly dark bark near my neighborhood instead of light-colored peppered moths.
