Do Now Homework Test on Friday Study session at 8 in this room on Friday morning. Do Now What is the most confusing concept from this unit? What are 3 examples of traits that might be favorable to animals or plants? Motivation Monday Tuesday

Objetives SWBAT describe natural selection by watching a BrainPop. SWBAT predict which populations are likely to survive in a particular environment by analyzing data. Essential Question How does natural selection change a population?

BrainPop What did Charles Darwin notice? What were his examples What are mutations? Describe what happens to the reef fish. Why does Darwin compare organisms to a giant tree of life?

Analyzing data

The Peppered Moth

Answer the Essential Question How does natural selection change a population?

The deer population fell in the neighborhood and rose in the sanctuary The deer population fell with the loss of vegetation and rose with the increase of vegetation The deer population continued to increase despite the loss of vegetation The amount of vegetation had no effect on the deer population Exit Ticket
