It's a powerpoint presentation on the story of Frankenstein. It's made for middle school children. Every slide has text on it. Simply read the text on a slide and then move on to the next one. The questions at the end could be skipped, used, or even changed. The slide before the last slide is supposed to be question time about the topic.
Time: It should be about 5 minutes if you go quickly. 15 minutes if you take your time and have curious students at the end.
