Each simulation allows students to select parental phenotypes and make crosses. With such programs, students will be able to simulate many generations of crosses in a single class period. All the programs allow students to begin with data and construct a model of the elements and processes of an inheritance pattern. Students will be able to use the model to predict the phenotypes and genotypes of future offspring and check predictions by making the crosses. Ms. J. chooses one of the simulations after reviewing it carefully and considering the budget she has for supplies.
Enough computers are available to permit students to work in teams of four.
Students will work in their teams to develop models of inheritance patterns during the first quarter. Ms. J. plans to obtain reprints of Mendel's original article for students to read early in the quarter. It has a nice model for an inheritance pattern, and students will examine it as they identify elements of a mental model. In addition to using the simulations, Ms. J. wants students to work with living organisms. She will need to order the proper yeast strains, fruit flies, and Fast Plants.
