Here is an introduction worksheet to The History of Evolutionary Thought video from Teacher's Pet (video link is embedded at the top of the worksheet). There are eight questions that go along with the video. There is one HOT question short answer response that students can use their just learned material about the topic to help them explain how natural selection through time changes genetics in a population.
There is a project that helps students further understand natural selection by having them develop two organisms (a plant and an animal) living in an extreme ecosystem. Rubric is included.
This worksheet can be used in class, at home, or for review. Great for middle schools students who are being introduced to this topic. Good review for high school students who need to have a quick review.
