Homework last night… Dichotomous Key by Mark Drollinger Due tomorrow at the beginning of class. Yes, there will be a quiz. Time on the video is only 2:39. 

Quiz Time Quiz tomorrow: know these terms You will have 7 minutes to complete the quiz Open your journals when you return to your seats Quiz tomorrow: know these terms Kingdom Taxonomy Family Genus Scientific name Class Taxon Phylum Dichotomous Key Species Domain Binomial Nomenclature Linneaus Order Cladogram

Taxonomy Recap… MORE EXCLUSIVE (INCLUDES LESS) MORE INCLUSIVE (INCLUDES MORE STUFF) MORE EXCLUSIVE (INCLUDES LESS)

Taxonomy Recap… ORAGNISMS MORE CLOSELY RELATED ORGANISMS BECOME LESS RELATED ORAGNISMS MORE CLOSELY RELATED

Taxonomy Recap… If an organism is in one Taxon, then it is automatically included in any taxa above it! But not necessarily included in the taxa below it

Dichotomous = divided or dividing into two parts Scientists use dichotomous keys and field guides to help people identify organisms Dichotomous key – tool that asks a series of questions that can be answered in only two ways Each answer leads to another question which will eventually leading to the item’s identification Sometimes represented as a flow chart

Dichotomous key Example 1: EXPLORE: Introduce your students to the dichotomous key. Together, use the key to identify the group to which each organism belongs. Assign the student reading. You may also wish to direct your students’ attention to the “Kingdoms” animation which is accessible from the multimedia lesson home page.
