Use of Dichotomous Keys to Identify Stream Organisms
What kind of organisms are living in the stream? After an explanation on how to use a dichotomous key, groups of three to four use the keys to identify macroinvertebrates from a local freshwater stream. Using the the concept of Stream...

Student Dichotomous Key for Insects
In this student dichotomous key worksheet, learners work in groups to create genus and species names for a list of insects assigned to them. Students then create a key for the new names given to their assigned list of insects.

Dichotomous Key for Identifying Pine Trees
Middle schoolers identify the species of pine trees that are found in their area. They use unlabeled "mystery" samples and a dichotomous key to identify the pine trees to species. After identification, they use a field guide to answer...

Classification of Cerealites
Students create a dichotomous key. In this categorizing lesson plan, 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...

Insect Pitfall Traps
Students ask testable questions, use the inquiry cycle to investigate, gather data and interpret the results, study the diversity of insects and other smallorganisms which live around the school; they can make an inventory /collection of...
Michigan State University
Bug Lyphe!
Introduce ecology classes to biodiversity and interdependence in ecosystems with a PowerPoint presentation. Then, they get up-close and personal with the invertebrate world by collecting insects, classifying them, and graphing their...

The Key To Classifying Animals
Explorers of the environment construct a dichotomous key for a variety of organisms and design a key to classify Galapagos animals based on descriptions and images. The lesson includes a link to an animal gallery and the worksheet for...
Curated OER
Insects
Students construct a viable insect collecting apparatus. Students determine the effectiveness of the instrument he has designed by collecting specimens.

Exploration of 'pill bugs'
Fifth graders define words. They create a dichotomous key. After carefully examining pill bugs, 5th graders record observations. They compare and contrast habitats of pillbugs.

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...

Spot Identification of Some of the Most Common Insect Orders
Students investigate the basic characteristics of insect orders and develop short-cut techniques to identify insects into twelve of the most common orders. They use captured specimens and photographs to practice identification and then...
Curated OER
INSECTS
Seventh graders select, collect, and classify various insects by constructing an apparatus from materials that aid in the capture and containment of the insect.
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.

What Critters Tell Us About Water Quality: A Macroinvertebrate Lesson
Students explore our ecosystem by investigating the quality of our water. In this aquatic insect lesson, students examine a group of random insects collected from different streams and ponds in the area. Students record their...
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
Arthropod Key
Students identify the types of pests and categorize them. They identify their food chain and create a poster showing the food chain for the pests.
Curated OER
Into the Pond
Seventh graders use a pond to explore macroinvertebrates and other organisms. They use a dichotomous key to classify the organisms and maintain a journal recording their findings.

How Appropriate is that Tree?
Students identify trees and their environments using a dichotomous chart. In this exploratory lesson students use the Internet to identify conditions needed for the trees and what the climate is in their area.

Pond Ecology
A lab activity is a great way to incite thoughtful questioning and scientific processes. Pupils will collect organisms with a Petri dish, make observations, sketch the organism, ask questions, then attempt to identify the specimen...

SORTING ALL SORTS
Students examine how the method of classification is used. In this sorting lesson students take a pre-test, classify organisms and complete a crossword puzzle.
Curated OER
Soil Organisms
Students work together to collect soil samples from different locations. In the samples, they identify the macroorganisms and classify them. They identify the conditions that affect how macroorganisms grow. They also analyze and identify...

Benthic Macroinvertebrates
Students survey and describe a stream ecosystem. They sample the benthic macroinvertebrate populations of a given stream and determine community structure through the use of the Chandler Index and a species diversity index.
