After a thorough examination of the process of evolution, it is time to apply our learning! We will begin with a PowerPoint to briefly discuss the concept of infectious organisms, with an emphasis on thinking about how the co-evolution of organisms has resulted in complex relationships between organisms. Students will define the vocabulary terms of host, bacteria, virus, parasite, and infection. Next, we will watch a National Geographic video about zombie parasites. The presenter, Anand Varma, applies his expertise in photography to the study of parasites. Mr. Varma travels the world collecting specimen for study, and his ability to apply biological concepts to his work, think creatively, and drive to overcome failure make him and his work truly remarkable.
