Biology Unit 3 Day 3 Part 2

Learning Objective: Students will learn about natural selection by doing a simulation and will analyze and interpret data in writing using technical vocabulary (variation, adaptation, mutation, fitness, limiting factor, exponential growth) and science ideas (cause and effect).

Questions:

1. Give an example of an inherited  behavior that a plant or animal has. (book or brain)
2. What factors might limit a population or species from growing? (book or brain)
3. Why is it impossible for exponential growth to continue forever?

Choices for number 3:

	A. Organisms start to compete for resources. B. Mutations happen randomly in organisms. C. Most ecosystems have unlimited water supplies. D. A population has no genetic diversity. Exit Ticket for Day 3: How would you explain natural selection to a classmate? What would be the most difficult thing for you to explain? (explain why you think so).
