This assignment conducts a thorough exploration of systematics. Clearly designed for an AP biology course, questions pertain to taxonomic categories, phylogeny, and construction of cladograms. 

Carolus Linnaeus designed the binomial nomenclature system of naming organisms that is still in use more than 200 years later. By viewing this PowerPoint, upcoming biologists learn how to use it. They are also introduced to the hierarchy...

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...

Biology learners will be able to explain the binomial nomenclature system and name the seven levels of classification of living things after viewing this set of slides. Brightly colored with bold fonts, the format is eye-catching, and...

A set of note-taking slides introduces your biologists to the characteristics and the four subphyla of arthropods. Nothing flashy is included, but it is a tidy and straightforward presentation that you can use when your class is studying...

In this Prokaryotes and Protists worksheet, students are given details about the Kingdom Monera and Kingdom Protista. Included are examples of the species in each kingdom, the characteristics of each kingdom and how the species are...

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...

Here is an interesting set of slides that give some nice examples of the reasoning behind scientific Binomial Nomenclature. Some examples of scientific naming are given along with their common names. There is not much more detail on the...

Seventh graders explore how to classify insects and organize information.In this insect classification instructional activity students use the Internet to retrieve information on insects then organize the pictures to make a book project.

In this biology worksheet, students complete a crossword puzzle with 39 questions on taxonomy. They identify the different classification systems used in biology.

Tenth graders explain how organisms are classified according to similarities. In this biology lesson, 10th graders research on five different organisms of their choice. They prepare a report and presentation about them which they share...

Students identify the different taxonomic classifications of organisms. In this biology lesson, students create their own organisms and make some changes according to environmental conditions. They present their work in class.

Seventh graders explain the importance of taxonomy. In this biology lesson, 7th graders classify organisms accordingly. They develop a mnemonic to help them remember taxonomy levels.

Students describe the techniques biologists use to classify organisms. In this biology lesson, students create cladograms and phylogenetic trees. They list the levels of taxonomic hierarchy.
