HIV is a virus that is transmitted by fluids form person to person. When it is introduced into a population it can be transmitted at a high or low rate, depending upon the lifestyle choices of the members of that population. We used a solution and indicator to model the rate of transmission in a Living Environment Lab activity. Students were assigned lifestyles that were not indicative of their actual life, but rather roles that they were playing to demonstrate the differences in the transmission of the disease. The students kept track of who they mated with (shared fluids) and in what order they mated. Once the activity was completed they used their recorded data and sheets to build a flow chart in math class. This flow chart allowed them to pinpoint the person who had the original disease. From this information they graphed the transmission with excel and built a model with AgentSheets to study ways of preventing HIV transmission and infection.
