Make your own Dichotomous Key

Make your own Dichotomous Key

Lesson from Oregon Ag in the Classroom.

Description: In this lesson students will have fun learning about Dichotomous Keys.
“Dichotomous” means “divided into two parts.” Therefore, dichotomous keys always give two
choices in each step that lead the user to the correct name of a given item. A “key” is a tool that
allows a user to determine the identity of items in the natural world, such as trees, wildflowers,
mammals, reptiles, rocks, and fish.
