These five laboratory activities are designed for observation of primates and humans in a zoological environment and include studies of locomotion, communication, mother-infant interaction, general behavior, and dominance/submissive behavior. Students make observations and interpretations. Full description.

This site provides information on Canadian species and contacts for finding species data. The information is categorized by: Aquatic Invertebrates; Birds (Aves); Butterflies (Lepidoptera); Fish (Agnatha, Chondrichthyes, Osteichthyes); Molluscs (Mollusca); Mosquitoes; Plants (Plantae); and Reptiles and Amphibians (Reptilia and Amphibia). The specimens can be searched by listing the number of records ... Full description.

SpeciesBank is a growing library of digital information about the biological species of Canada. It includes high-quality photographs, distribution maps, identification guidance, and a host of other information including links to monographs and species-specific information elsewhere on the Internet. The site is divided into sections that cover butterflies, brassicaceae, poisonous plants, moths, and ... Full description.

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. ...

This lesson compares in detail the banding patterns seen on stained chromosomes from humans and chimpanzees, showing striking similarities. Possible evolutionary relationships are explored, as are the chromosomes and relationships of other apes. Full description.

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 ... Full description.

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.

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.
