Compare what shells look like on the outside with what makes that happen on the inside. Scholars begin by sorting an various seashells by their physical characteristics into phylogenetic trees. They then conduct a DNA comparison of...

Are spiders related to crabs? Study the order of arthropods with a reading selection about animal diversity. It provides details about each class within the order, as well as vivid pictures and explanatory charts. 

Compare protein fragments, count amino acids, and use the information to explore common ancestry. The resource mentions a student worksheet, however, a separate printable worksheet is not provided. The exercises are written into the...

Students observe the two major developmental pathways (protostome and deuterostome). They analyze data regarding differences in nucleotide sequences and construct a phylogenetic tree. They observe the similar evolutionary history shared...

Students construct cladograms (evolutionary trees), showing how shared derived characters can be used to reveal degrees of relationship. They interpret and analyze cladograms, and determine where unclassified vertebrates would fit on a...

Young scientists use the Internet to evaluate how organisms are classified. They research the phylogeny of organisms and how they are linked in a certain way. Pupils hone research technology skills with their final presentations.

Students complete a short quiz reviewing classification. In groups, they create their own family trees and discuss who is related to whom and are introduced to phylogenies in genetics. To end the lesson, they take notes on Taxonomy and...

A detailed website that explains the history and process of classifying animals using evolutionary, molecular, and physical characteristics relationships. Website also contains information on evolution and evolutionary processes....

Alphabetical listing from the University of California of info on each of the animal phyla. Includes scientific and common names and photos. Characteristics of each group are explained in detail.

Take an interactive quiz over the classification of living things. After completing the quiz, check your score, and then revisit any incorrect question for further review.
