What is a Branching Diagram? Definition A branching diagram is a diagram that shows the relationships among biological species based upon similarities and differences in the physical and/or genetic characteristics. Purpose The purpose of a branching diagram is to examine the relationship and common characteristics between organisms. Objective: Can I use a dichotomous key to identify an unknown organism?

Whole Class Objective: Can I use a dichotomous key to identify an unknown organism?

What is a Dichotomous Key? Definition A dichotomous key is a tool that uses a series of paired statements to help someone identify the name of an organism when they are looking at the organism’s features. Purpose The purpose of the key is to name a creature. Sounds Like “Di-” means two. “Dichotomous” means divided into two parts. Objective: Can I use a dichotomous key to identify an unknown organism?

How to work a Dichotomous Key Step 1: Select the organism (Hint: look at this organism the entire time you are answering questions/ statements). Step 2: ALWAYS start at the first set of questions/ statements (1a and 1b). Step 3: Once you answer the questions/ statements, follow the directions to the next set of questions/ statements. Step 4: Continue answering statements until you reach a name. This is the scientific name. It should be a 2 part name: Genus species. Step 5: Select the next organism and repeat steps 2-4.
