Objective: SWBAT will be able to observe physical traits in order to describe variation amongst a population.
Do Now:
Question 1
1.
Below is an image of a rainforest in Ecuador. The frogs (also pictured below) live there and are all the same species, a type of dart frog. Observe the frogs closely and describe them below
Describe the group of frogs in the image.

Why do you think the butterfly population above is different for each butterfly?
Question 5
5.
What could have changed in the environment that would cause some butterflies to have yellow and less brown on their wings?
