The only criteria you will be judged on will be the length and on whether you did it or not. The main difference on this speech is that the class and the teacher will evaluate your performance immediately after you complete the assignment before the entire class. This makes it a particularly useful, but potentially painful, class period, so be prepared. You are to deliver an informative or demonstration speech to the rest of the class. You must use at least two sources from the library or from expert interviews.
More sources are probably better.
You get to choose the topic. The speech must be between six and eight minutes in length. You will be timed, but you will receive no cues. The speech must be extemporaneous, that is either memorized or from notes. Visual aids are required.
