Students, after exploring and analyzing diagrammatic and taxonomic keys and their association to marine sciences, identify and classify objects and organisms based on visual attributes/characteristics. They research and create their own...

An overview of the five kingdoms within the biological classification system is presented in this set of five slides. The first lists the objectives of the slide show, and the second gives general characteristics of plant, animal, and...

Students explore the classification system in this seven lessons unit. The diversity of life forms and their characteristics are examined using a microscope. Kingdoms, classes, and families are investigated.

Students practice using a dichotomous key. For this classification lesson, students read an article about scientific exploration and identification of new species. They use a dichotomous key to identify objects and create their own key.

Young scholars participate in a creative activity to give them a good understanding of classification. They examine bags of chips and discuss their similarities and differences. Students work in small groups while participating in this...

Learners investigate various tree leaves and use a dichotomous key to classify the leaves. In this leaf classification lesson, students study various types of leaves and their Genus. Learners record observations for each Genus.

Learners classify imaginary newly discovered organisms. In this classification lesson, students are given cards showing imaginary organisms that have been recently discovered. They must classify the organisms based on their characteristics.

Students practice using 2 different plant classification keys to identify species. They make choices between the similarities and differences between their object and the classification scheme.

Learners examine the world of forensic science, focusing on fingerprint analysis. In the lesson, they implement a method by which fingerprints of class members are categorized and identified. Elementary students study classification...

Young geologists learn how to use an identification key in order to classify rocks. The key is designed to help them classify rocks into three types: ignesous, metamorphic, and sediimentary. After an initial teacher-led demonstration,...

A slideshow that covers the all-important details related to basic human circulation. The reasoning for exchange of material methods is presented and then labeled diagrams of the main human transfer systems are shown, along with...

Students classify animals into six major animal groups and describe the characteristics of the animals found within each group.  In this living and non-living animals lesson, students observe a variety of animals, both living and...

Learners identify tree species by their leaf characteristics. In this dendrology lesson, students learn leaf vocabulary and collect leaves. They identify the leaves using the leaf characteristics and the vocabulary that they learned.

Second graders study animal characteristics and classification. In this animal characteristics and classifications lesson, 2nd graders determine how to classify vertebrates which include mammals, reptiles, amphibians, birds, and fish....

Students draw comparisons between organisms. They classify organisms. Students are introduced to dichotomous keys and how to create and use a dichotomous key to identify a variety of objects. They begin by defining classification, and...

High schoolers define the concept of classification. In groups, they categorize a series of objects into categories they identify. As a class, they participate in a variety of activities to examine the concept of natural selection. To...

Fourth graders participate in a variety of activities dealing with animal characteristics and classifications in this multi-task lesson plan. They use graphic organizers, make booklets, and make models.

Students examine a method biologists use to try to determine relationships. They examine how amino acid sequences have been determined for a number of proteins, and how scientists can make inferences about DNA based on the amino acid...

Students minerals and how they form. They investigate the classification of minerals according to physical properties. Students watch a video about mineral characteristics. In groups, students participate in hands-on activities and...

In this classification activity, students are given nine pictures of different types of fish. They cut them out and use a key to classify each into a category based on their characteristics.

In this star classification activity, students are given laminated star charts to make observations about stars. They work in groups to classify groups of stars based on different characteristics. For each group of stars they list at...

Students use their senses to record and collect data. In How Do I Classify Things in My World?, students practice classifying objects as living or nonliving. In Is it Real Or Pretend?, students group objects as real or pretend. In What...

Students construct a periodic table using felt strips as elements by arranging elements based on their characteristics. In this periodic table lesson plan, students place colored strips of paper that represent elements in the proper...

Students familiarize themselves with the interconnectedness of species within an ecosystem, and to use this knowledge to evaluate how the removal or decimation of one species can have far reaching effects.
