Moth Lab- Who survived?
Problem: Did the industrial revolution play an effect on the specled moth population?
Research:
Research:
- Durning the industrial revolution in england the lighter colored moths went exticnt because the trees were blackened with doot from factories.
- Because that species went extinct a new adaptation caused a new species called the peppered moth
- "industrial melanism" is a term used for when species have to adapt because of harmful polution
- The black moth is much harder to see on black trees, while the white is harder to see on white trees.

Hypothosis: The industrial revolution will decrease the population of the peppered moths.

Claim:
The white peppered moth population
decreased during the Industrial Revolution.
Evidence:
Before the industrial revolution or years
1,2, and 3, the white moth population was, year 1: 10 moths, year 2: 13 moths,
and year 3: 17 moths. While, the black population was, year 1: 8 moths, year 2:
7 moths, year 3: 5 moths. Then, the industrial revolution started on year 4 and
the white moths’ averages were, year 4: 7, year 5: 6, year 6: 5, year 7: 4, and
year 8: 2. Yet, the black moth’s population starting at year 4 was, year 4: 6,
year 5: 7, year 6: 9, year 7: 12, and year 8:
14.
Reasoning:
The speckled moth population decreased due
to the industrial revolution. When
the industrial revolution started in year four, the white moth population
decreased by 10 moths and the black moth population increased by 1 moth. When
the industrial revolution started the gas and smoke from factories covered the
trees and houses with soot, making the white moths easier to spot by predators,
causing them to get eaten. However, the black moths were much harder to spot,
because the color of the black moth camouflaged into the black trees and houses.
Therefore, decreasing the white moth population drastically.
