Students pass a contagion, Serratia marcescens (non-pathogenic, opportunistic bacteria that forms bright red bacterial colonies), through a series of recorded handshakes. The gloves used in the handshakes are swabbed after the first 2 handshakes and after the fourth. ANy errors in procedure can be discussed with reference to problems in reposting in actual epidemiological studies. I first created this lab while teaching a non-science major course in Microbiology at San Diego State University in 1972. This is an excellent laboratory for developing critical thinking skills.

This activity explores the relationship between genotype and phenotype, using both sex-linked and autosomal dominant and recessive traits. By manipulating alleles (genotype), you create corresponding changes in the dragon's physical appearance (phenotype).

Parts 1 and 2 of this lab demonstrate basic principles of meiosis, fertilization, and inheritance using the same pea traits that Mendel studied. We suggest you start at the beginning to brush up on the basics. But if you just can't wait to play the game, skip ahead to part 3, The Princess and the Wrinkled Peas.

Plant Evolution Lab

by Alison Loomis

By the end of this exercise, you should be able to identify the various lignified cell types in cross sections of stem. You should know how to tell a moss from a fern; a gametophyte from a sporophyte. You should understand which cells are haploid and which diploid, and whether they are formed by mitosis, meiosis, or fertilization. You should be able to apply this information to the reproductive cycle in gymnosperms such as pine. The objectives of this lab are as follows: 1. To look at cellular specialization in plants, with emphasis on lignified cells that function in water transport and/or support. 2. To study the evolution of these vegetative structures in representative plants: a moss, a fern, a gymnosperm, and both a woody and a nonwoody angiosperm. 3. To examine the evolution of sexual cycles in a moss, a typical fern, and a gymnosperm.
