Students examine the genetic relationships of different organisms. In groups, they discover the importance of genes and how different amino acids show various evolutionary relationships. They use an online database to continue their...

Students analyze relationships about animals and create a model of classifications based on both the similarities and the differences. They also discuss a dichotomous key before they create a cladograph using different types of candy.

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 observe the structures of skulls as presented in drawings, and determine which are most closely related to the skull of the mosasaur.

Young scholars analyze different regions of the brain which are responsible for different aspects of cognition, awareness and regulating the body's process.

Students examine the molecular studies of organisms that have led to a new era in their understanding of speciation and evolutionary relationships. Students study the allelic frequency of genes controlling specific molecules and assess...

In this classification of life worksheet, students use an on line source to answer questions about how species are classified, named and grouped. They give the classification of a bear, an orchid and a sea cucumber.

In this relationships and biodiversity worksheet, students investigate the relationships between 4 plants sample using 7 different tests. These include looking at structural characteristics of the plants, seeds and stems, using paper...

Students read the essay, "What, If Anything, Is a Zebra?" following a teacher made reading guide. They investigate cladistics, shared derived characteristics, with further online research to enhance their study of evolution and...

Students explore how biological classification is intimately associated with evolution.

For this earth history worksheet, high schoolers visit a website and complete 15 fill in the blank and 8 short answer questions based on what they read. Topics include biodiversity, animal kingdoms, evolution, fossils, and extinction.

Students analyze protein sequences. In this lesson on determining evolutionary relationships, students use the Internet tools BLAST and Biology Workbench to look at protein sequences. Students will compose an essay that includes their...

Young scholars "take a trip" to the Greater Antilles to observethe Anolis lizards. They study the body structures and habitat of different species, then plot this data on a map to look for patterns in their distribution. From the...

Learners investigate sets and subsets as they group coins and dinosaurs. Using scissors and provided sheet, they sort dinosaurs according to their commonalities. Their groupings are shared with the class.

Students examine diversity on the planet and the differences within a species.  In this investigative lesson students complete a lab that allows students to better understand the relatedness between plants. 

Learners examine groups of hierarchy and see how primates are categorized.  In this primate classification lesson students view video and slides then examine the taxonomy of primates. 

Students, in groups, classify furniture, share their categories and rationales, then note how their different schemes vary, perfectly logical and useful, but completely arbitrary.

A lesson plan where students analyze a cladogram to understand a derived characteristics between a group of organisms. After analyzing the prepared cladogram, students create their own.

This lesson plan requires young scholars to analyze DNA restriction maps to determine the differences in the sequence for several primates and humans. They then use the information to create a cladogram.

Learn about the diversity of species on Earth by exploring a cladogram, a graph-like tree of life that illustrates relatedness among species. Includes instructions for reading cladograms and a pie chart that summarizes the percentages of...

[Free Registration/Login may be required to access all resource tools.] Identify the differences between Phylogenetic Classification and the Linnaean Classification systems. Recognize and know how to interpret a phylogenetic tree and a...

Launch this OLogy link to find a dinosaur cladogram, an illustration that organizes dinosaurs into groups based on the unique characteristics they share, like a three-toed foot.

Most native plants are not very well studied. One way we learn more about these plants is by studying the species of plants they are most closely related to. In this science project you will sequence part of the chloroplast genome from a...

The title could be slightly misleading for this site. It is actually a teaching and learning module on the science of cladistics. As they go through the module, students will increase their understanding of, and appreciation for, the...
