Problem
Did the Industrial Revolution effect the population of the speckeld moth?
Research
Moths eat: Caterpillars, and plants
Industrial Revolution polluted the air, water, and soil. More people cut down trees. People who lived in industrialized countires left rural areas and heavily populated urban areas.

Hypothesis
The Industrial Revolution did affect the population of the speckeled moth by making it increase and made the population of the light colored moths decrease.
CER
Claim: The Industrial Revolution did effect the speckled moth population. It increased the population of the speckled moth while the white moth population decreased.
Evidence: The ratio of the white moth population to the black moth population before the Industrial Revolution was 17:5. Five years after the Industrial Revolution the same ratio changed to 2:14. The average population of the white moth population after the Industrial Revolution was 5 and the average population of the black moths was 10. But, before the Industrial Revolution the average white moth population was 14 and the average black moth population was 7.
Reasoning: We know that the Industrial Revolution did effect the moth population because of the pollution it gave off. The black moths were able to blend in with soot covered trees better than the white moths. Predators were able to pick out the white moths easily so their population decreased. We know this because the average white moth population before and after the Industrial Revolution has a big difference. It used to be 14 and then it became 5. The black moth population on the other hand increased. it used to be 7 and it raised to 10.
