Moth Lab
Problem: How will the Industrial Revolution affect the moth population.
Research: Female white moths are larger, however, female black moths are smaller. the Industrial Revolution covered the white trees in soot, leaving the white moths exposed and the black moths hidden. The peppered moths are eaten by flycatchers, nuthatches, and robins.
Hypothesis: Due to the pollution that blackened the trees, the white moths will stand out to predators and their population will go down.

CER Conclusion
Claim: Over time, the population of black moths went up, and the population of white moths went down.
Evidence: The average population of white moths in the first four years was 12 and the average population of black moths was 7. In the final four years the average population of white moths was 4 and the average population of black moths was 11. By the eighth year the black moths outnumbered the white moths by a 7:1 ratio.
Reasoning: In the first four years the average population of white moths out numbered the black moths because the Industrial Revolution hadn't begun yet. In the second four years the average population of white moths was 4 and the average population of black moths was 7. This is because the soot from the Industrial Revolution caused the trees to turn black and the white moths were more conspicuous to predators so their population went down.
