What is natural selection?

This minds-on, analysis and discussion activity introduces students to the process of natural selection, including key concepts and vocabulary.

In addition, students analyze several examples to learn about the conditions that are needed for natural selection to occur.

(This activity is an expanded version of the first section of the hands-on activity Evolution by Natural Selection.)

The Student Handout is available in the first two attached files and as a Google doc designed for use in online instruction and distance learning. The Teacher Notes, available in the last two attached files, provide instructional suggestions and background information and explain how this activity is aligned with the Next Generation Science Standards.
