Write a detailed post on your subject of interest. Assume that no-one else in the class knows anything about this subfield and explain it to them in enough detail that they will understand it clearly. You can augment your post with images/graphics/video clips that you find online, but you must name the source(s) for any used. For example, lets say that you find a really great YouTube video that illustrates your topic in a clear or interesting way. You are encouraged to include it as part of your post, but make sure to give the web address for the video. If you use any images or utilize any particular websites or articles to formulate your post, youll need to list those sources as well.
