This lesson is one small part of a larger science unit from www.sciencepowerpoint.com. This unit comes with a bundled homework package, detailed lesson notes, worksheets, review games, and much more. Students learn about Parasites and then create their own PowerPoitn about a Parasite. I usually have the whole class run their presentations on their laptops. I turn out the lights, play some creepy music and the students roam the room visiting presentations and recording information. This lesson is just one small part of my curriculum.
