Dichotomous keys are a fun topic to teach! This very low-prep, two-day lesson prepares students to construct their own flowchart and dichotomous key using organisms of their choice.
This is a two-day lesson that allows students to climb Bloom's Taxonomy. The lesson includes the following:
--the concept of organizing things into “dichotomous” (to cut into two) groups using the included "tools cards"
--how to turn dichotomous grouping into a flowchart (the "tools" activity)
--flowchart practice worksheet
--how to turn a flowchart into a dichotomous key (worksheet)
--directions for students for constructing their own flowchart and dichotomous key, and a grading rubric for the teacher!
Students really enjoy choosing the favorite and obscure animals to include in their projects, and these Dichotomous Key/Flowchart projects make lovely classroom decor!
Thanks for looking!
