BIRDD is a rich collection of primary scientific data and supporting materials about the Gal·pagos Islands and Darwin's finches.
Genetics Construction Kit is a simulation of a classic Mendelian genetics laboratory. It provides students with a set of organisms with unknown patterns of inheritance, and gives them the tools to design and perform a series of experiments to discover these inheritance patterns.Students will be able to cross the unknown organisms and analyze their crosses in ways much like those used by practicing scientists.GCK provides several tools for analyzing and organizing data: * Vial Summary Chart summarizes the contents of a vial or set of vials * Cross Matrix records the crosses made so far and indexes the vials generated by these crosses * Chi Squared Worksheet allows students to test whether observed numbers differ significantly from the ratio expected under a given hypothesis.GCK comes with several predefined problems designed to present a different aspect of genetics or to illustrate a particular problem. In addition, by using the problem editing utility, it is possible to customize a problem to meet your specific needs.
A text chapter that introduces and explores some of the key issues in the 3Ps (Problem-posing, Problem-solving, and Persuading Peers) philosophy behind the activities of the BioQUEST Curriculum Consortium and the materials included in The BioQUEST Library.
A µGCK problem starts with a field collection of bacteria, either in a test tube or plated onto a petri plate. Each of the gray circles on the plate represents one colony. These colonies result from bacteria collected from the field. The colonies are of unknown genotype and phenotype, although all bacteria within a colony share a genotype and phenotype.µGCK includes several tools to help organize and analyze the data that are collected during an experiment. The Media Matrix window displays the media used by all current plates and tubes; phenotype worksheets record the phenotypes of colonies; complementation worksheets record the complementation behavior of a plate's colonies.µGCK comes with several predefined problems designed to present a different aspect of microbial genetics or to illustrate a particular problem. In addition, using the problem editing utility, it is possible to customize a problem to meet your specific needs.
