Moth Lab
Problem: How does the industrial revolution affect the population of speckled moths?
Research: Speckled (Peppered) Moth-
Hypothesis: Once the industrial revolution starts then the lighter speckled moth population will decrease and the darker speckled moth population will increase.

Conclusion
CER:
Claim: Natural selection will occur once the industrial revolution.
Evidence: The white moth population was thriving before the industrial revolution hit the ecosystem. The average population of the white speckled population was approximately 13 before the industrial revolution hit. The black speckled moth population however was dying out. The average of the black speckled moth population was about 7 before the industrial revolution began. However, after the industrial revolution the white speckled moth population kept on a steady decline and, if the pattern continues, will eventually die out. The black speckled moth population will starts growing because they can camouflage into there surroundings. In fact at the end of year 8 the population is 14. That is a 12 moth difference between the black moth population and the white moth population.
Reasoning: The data that is shown here is natural selection taking place. As natural selection goes only the favorable traits will be passed on and only the strongest will survive. In this experiment only the moths with favorable traits were able to survive and thrive. The first three years the moths with the favorable trait, white color, were able to survive. The black moth population however was dying out. But once the industrial revolution started and the favorable trait was switched to the black color the black moth population started to go up.
