This applet explores Mendel's ideas about dominant and recessive traits. The student chooses the leaf and stem colors of the parent plants before pollination, and the applet displays the resulting plants of the next generation. The student then chooses from this second generation the parents of the third generation, the offspring are displayed, and so on. The experiment can also be conducted using ... Full description.

In this lab simulation students conduct a modified Ames Test, which predicts carcinogenicity of chemicals. Students are provided with a virtual strain of Escherichia coli that is sensitive to (killed by) the antibiotic streptomycin, several virtual chemicals to test for mutagenicity, and two types of media (nutrient Agar and nutrient Agar + Streptomycin). The simulation allows students to propose ... Full description.

In this lesson about the origin of life, students will learn that under suitable conditions, life-like structures can form naturally from relatively simple materials. Students will mix a carbohydrate solution with a protein solution, adjust the pH, and view coacervates: amoeba-like objects, which change shape, flow, merge, divide, form vacuoles, release vacuole contents, and show other life-like properties. ...

In this lesson students prepare the components for building a Colossal Classroom Cladogram of vertebrate evolution, then put it together, showing the gradual, mosaic accumulation of the traits which humans possess. A major purpose of this is to dramatize the evidence that we (and in fact all living things) did not suddenly pop into existence, but clearly evolved as an accumulation of traits over vast ...

This lesson introduces students to the building of cladograms as evolutionary trees showing how "shared derived characters" can be used to reveal degrees of relationship. Given some groups of organisms and some of their distinguishing characteristics, the students will construct a cladogram. Given a cladogram, the students will properly interpret and analyze that cladogram in terms of recognizing ... Full description.

Comment on this resource
In this lesson amino acid sequences in cytochrome-c are compared for several different animals, and the number of differences found are used to infer degrees of relationship. This data is also compared with a cladogram constructed for those same animals from their anatomical features, providing an example of independent confirmation. Full description.

This lesson is based on an article that explains what cladistics is, why it is useful, how it is applied, and what its limitations are. Students will learn that biological classification is intimately associated with evolution; that there are many problems encountered in classification, which is evidence that the living world is a work in progress, and evolution provides an explanation for those problems. ...

This lesson is based on an essay by Stephen Jay Gould and on the related reading guide. It addresses the issue of cladistics and some of the problems encountered in the science of Systematics. Students will learn that biological classification is intimately associated with evolution. They will also learn that there are many problems encountered in classification, providing evidence that the living ... Full description.
