Classify Machines that Fly!
Eighth graders explore flight and the dichotomous key. In this flight lesson, 8th graders gain understanding of the dichotomous key and create one of their own. Students then use their dichotomous key to classify types of aircraft.

Keys To Trees: Dichotomous Tree Identification
Ninth graders gather samples of different tree leaves in their neighborhoods, and on school grounds, and identify several species of common South Carolina trees using leaf and growth characteristics with aid of dichotomous key.
Curated OER
Jewel of the Earth
Students investigate several organisms, set sticky traps to collect them, and attempt to identify and classify them using a variety of sources. The origins of the organisms are traced and their adaptive features examined.

Freshwater Fish Anatomy & Taxonomy
Tenth graders use a classification key to identify organisms. In this classification lesson students identify freshwater species of fish and document their observations.
Curated OER
Bean Sort
Students define and discuss dichotomous keys. They create a dichotomous key to identify a bag of mixed beans, and assign their group of beans a genus and species name.

Primate Evolution- Family Ties
If humans evolved from apes, why are there still apes? Using captivating pictures and videos of our primate cousins, young biologists examine evidence to dispel one of the most common misconceptions about human evolution. Depending on...

Exploration of "Pillbugs"
Fifth graders define vocabulary terms, identify the characteristics of a pillbug, and create a dichotomous key. Then they examine the pillbugs and make observations and record these observations. Finally, 5th graders observe specific...

Taxonomy
Biology novices name the seven levels of classification and use binomial nomenclature for naming living organisms. The first half of this presentation bestows a brief history of taxonomy, while the second half instructs on how to use our...
Curated OER
Tree Identification
Students are introduced to the characteristics of trees and different techniques to identify them. They distinguish between a deciduous and a coniferous tree. Students describe at least four characteristics used to identify trees. They...

Plant Features
Pine needles are actually modified leaves. In the 16th installment of 20, young scientists explore plants. Through an analysis of leaves — shape, veins, and edges — pupils see how to classify plants based on structural features.
Curated OER
Backyard Bugs
Explore the concept of scientific classification and the similarities and differences between plant and animal species. Your class will participate in hands-on activities by investigating dichotomous keys and classifying their shoes. To...

Donut Sort
Third graders create dichotomous keys using donuts. In this dichotomous lesson, 3rd graders review what a property is and sort donuts by a specific property. Donuts are kept in plastic baggies for the activity so they can be enjoyed by...
Curated OER
Biodiversity
In this biodiversity worksheet, students sort and classify animals by their observable features using a dichotomous key. Students then respond to questions about complete and incomplete metamorphosis.
Curated OER
Classifying Rocks
Fifth graders examine and participate in the process of classifying rocks. In small groups, they sort the rocks into two categories and complete a Venn diagram. Next, they select three rocks, and complete a worksheet that is in the...
