Natural Selection and Antibiotic-Resistant Bacteria
Students use a model to explore the cause-and-effect relationship between inappropriate use of antibiotics and the phenomenon of the evolution of antibiotic resistance. This model is suitable when investigating bacterial infections in humans and other organisms, including livestock and pets. As they model the effects of antibiotics on the population of disease-causing bacteria they use mathematical representations to support their analysis of patterns and trends in the results. They then develop explanations for how and why the population of bacteria is changing and demonstrate that it is critical to remember to administer each dose on time and to complete the entire prescribed course of antibiotics.

Kit #906Tracking the Spread of Infectious DiseasesContagious diseases can spread quickly through a population. If an infected individual mingles with healthy individuals, random contact can cause many more to become infected. This activity simulates the transmission of a contagious disease and the steps epidemiologists take to try to determine its source and limit its spread. Two scenarios are provided, one...

Kit #91Natural Selection
In the 1950s, Oxford University scientist Dr. Bernard Kettlewell studied the changes in England's peppered moth population. Over a hundred year time period, the population of peppered moth shifted from being primarily light-colored moths to dark-colored moths. Dr. Kettlewell reasoned that predatory birds fed on more light-colored moths because they were more easy...

Kit #902SGenes, Mutations, Evolution, and Sickle Cell
In Part 1, students follow the inheritance of a hemoglobin mutation through two generations. Students identify patterns in their data and investigate the cause-and-effect relationship between environmental conditions (incidence of malaria, survival rates, and resource availability) and the frequency of a trait in a population. Based on their data collection and analysis, students construct explanations...
