Dichotomous Keys

  • Dichotomous means "divided in two parts".

  • Each step has two choices; what you choose leads you to another question until the item is identified.

  • Based on physical characteristics.

GROUP TASK

  • Each group gets ONE paper bag

  • Make a Dichotomous key for ALL the items in the bag.

  • Follow the Procedures.


Procedures

PROCEDURES

  • First make and answer key.

    • Write the names of your partners and bag # on your ANSWER key.

    • Assign a number to each object and make up a new name “scientific name” for each object.

      • Example: #1--------Mollusca minuta (small shell)

      • May want to trace an outline of the object

  • Make a dichotomous key for all objects in your bag.


Key format example
