AIDS: Evolution of an EpidemicBruce Walker, MD and Bisola Ojikutu, MD, MPH are passionate about fighting the global AIDS epidemic. Walker focuses on vaccine development in the lab, while Ojikutu works in the clinic and focuses on epidemiology. Complementing their U.S.-based research, each spends several months a year in Durban in South Africa’s KwaZulu-Natal province—a region at the epicenter of the AIDS epidemic in South Africa and the place with the highest incidence of HIV infection in the world.
Cell City AnalogyName:___________________________________________ In a far away city called Grant City, the main export and production product is the steel widget. Everyone in the town has something to do with steel widget making and the entire town is designed to build and export widgets. After the widget is constructed, they are placed on special carts which can deliver the widget anywhere in the city. Match the parts of the city (underlined) with the parts of the cell. 1. ** Create your own analogy of the cell using a different model.

5 Creative Ways to Teach the Cell1. 3 D Cell – this is a standard project for entry level biology classes, where students use various objects from around the house to design a three dimensional cell. Popular models are made of clay, cardboard, or styrofoam. Pros: Students seem to enjoy the project and you end up with a lot of amazing models. Cons: Can be expensive, difficult to store, or attract bugs if they are made of candy or other perishables, mostly done as individual projects. 2. 3. More Cells Created by Students 4. 5.
