Students define the word dichotomous and explain why a dichotomous key is a useful tool in identifying different species. Then they look up words they are unfamiliar with or mollusk reference books so students can learn the names of mollusk parts, which help them through the key. Students also try to figure out what shell they have been given and exchange shells with other students to practice using their dichotomous key.
Sixth graders classify candy according to observable characteristics. They use a dichotomous key to identify their bag of "treats." Thus, describe how dichotomous keys help to the identifying of organisms. Design a self-generated dichotomous key.
High schoolers become familiar with the structure and use of dichotomus keys. They demonstrate a comprehension of the fundamental principles of taxonomy by classifying organisms from a local ecosystem. Students are introduced to the term dichotomus key, and they are explained how dichotomous keys are structed and what they are used for.
Young scholars are introduced to the use of dichotomous keys as a simple means of beginning scientific observations in nature. They comprehend how to use a dichotomous key. Students distinguish characteristics of a group of organisms. They comprehend of the candy key to identifying plants.
Students construct a dichotomous key using 10 shoes from students in the classroom. In this dichotomous key lesson plan, students use the chalk board and their pile of 10 shoes to create a dichotomous key. They divide the shoes into 2 piles and define the agreed upon characteristics. They continue doing this for both piles and construct a key on the board. Students complete a worksheet about dichotomous keys.
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 own dichotomous key on a new group of creatures.
Students create their own dichotomous key. In this life science lesson, students classify organisms according to their characteristics. They explain how this method is useful to biologists.
Young scholars analyze how a dichotomous key helps us explain and identify unknown organisms. They design and construct a dichotomous key, developing a list of three observable characteristics per organism.
