Problem: How does the Industrial revolution affect the speckled moth population?
Research:
Hypothesis: Over time, the white speckled moth population is going to decrease as a result of the Industrial revolution which changes the color of the ecosystem.
Research:
- The English peppered moth were the best documented examples on natural selection.
- Speckled moths have spots on their wings.
- These moths live on lichens.
- During the day, they used to be camouflaged on the lichen.
- As industrial revolution started, soot started covering the lichens and the white speckled moths could not camouflage.
- As a result the White's population started to decrease drastically while the Black's were still camouflaged and hidden.
Hypothesis: Over time, the white speckled moth population is going to decrease as a result of the Industrial revolution which changes the color of the ecosystem.

Conclusion (CER) :
Claim:
As a result of the industrial revolution which brought a change into the color of the ecosystem, the white moths' population started decreasing drastically.
Evidence:
In years 1 to 3 when there was no pollution, the black moths population were low as in 8:10, 7:13, and 5:17. As the industrial revolution started taking place and pollution was forming in the air, the white moths population started decreasing. At the start of the black background at year 4, it was 7:6 and at the end at year 8, it was 14:2. [ Black:White]
Reasoning:
The Industrial revolution is a period of time when pollution was high in the air. The white moths could not camouflage into the lichen trees anymore, there was an advantage for the black moths as they could be camouflaged. The predator could not find the black moths easily but they could spot the white ones which led the predators to eat the white ones . The white moth's population decreased drastically due to the Industrial revolution.
