The folks at the BioEd Online website have crafted this very helpful set of educational materials for those who seek to teach their students about HIV/AIDS. The materials here will help students understand the virus that causes AIDS, how infectious agents multiply in organisms, and the worldwide spread of HIV/AIDS. The "Individual Activities" section contains five separate educational activities, including "Modeling an HIV Particle" and "Mapping the Spread of HIV/AIDS". Moving on, the "Other Resources" area includes a complete teacher's guide to all the materials, along with slides and videos that provide an introduction to viruses and infectious diseases. Finally, the site is rounded out by some "Nature News" which contains links to news pieces about HIV/AIDS research and related matters.
