Taxonomy: Who is in My family?
Find similarities in seemingly unlike organisms. The second instructional activity in a series of 12 builds the concept of a taxonomy and explores the use of a dichotomous key. Learners begin in part one by attempting to group a set of...
Cornell University
Classification
Explore the scientific method of classification. An interactive activity asks learners to create a classification system for a group of objects and develop a flow chart to communicate their systems. In addition, individuals use a...

Classification: Dichotomous Key
Learners investigate the classification process and nomenclatures used for classifying organisms. They study dichotomous keys to identify organisms with 90% accuracy. Students organize information regarding the relatedness of species.
Curated OER
Classification and Binomial Nomenclature
Students practice identifying different groups of living organisms using a dichotomous key. Students also examine the history of an organism and its lineage by writing a paragraph about it and "three generations" of ancestors.

Classification of Cerealites
Students create a dichotomous key. In this categorizing lesson, students create a dichotomous key for different types of cereal. Students classify the cereal into groups such as flakes and cereal with holes. Students discuss their...
Science 4 Inquiry
The Classification of Living Things
It's a classification sensation! Demystify why we classify using an inquiry activity that helps your class sort things out. Groups begin by classifying a variety of shoes before they research organisms and design their own dichotomous...

Vertebrates II
Mammals of the ocean unite! Or not. The 20th installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program investigates how warm-blooded marine mammals survive in water. In the class activity, learners use...
Curated OER
Using and Creating a Dichotomous Key
Students assess what a dichotomous key is and how it identifies objects in a group through a process of answering yes/no-type questions about certain objects. They examine an interactive graphic key on sea turtles and then create their...
