Classification: Dichotomous Key

Junior biologists journey through the hiearchy of living things with these activites. Using a dichotomous key, they identify common algae, plants, and fish. They design their own key for a mixture of seeds and a collection of...

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...

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...

Did you know scientists identify more than 13 billion species of organisms, and they discover more almost every day? An interesting presentation demonstrates how scientists keep track of so many species. It also shows how they...

Young scholars explain the classification process of organisms. In this biology lesson, students practice writing the names of organisms scientifically. They answer the dichotomous key and discuss answers as a class.

Young scholars are shown how to use the butterfly section of the Digital Altals of Idaho. They discuss how to make a dichotomous key. Students use their skills of observation and recognize defining characteristics that distinguish...

High schoolers 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.

In this taxonomy learning exercise, students use a dichotomous key for creatures found on planet Pamishan to identify each individual creature. This learning exercise has 20 creatures to identify.

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.

Young scholars collect and analyze pollen from different species of plants. In small groups, they classify pollen according to shape, size and physical characteristics. They draw the basic anatomy of flowering plants and create a...
