This can be done as a review of the organs after all the organ system have been gone over. Have students research an organ that you assign to the students. They must find out what system it is in, what it does to help the body, what disorders or diseases affect the organ, and if you can live with out the organ or not. The student then need to go around and ask students questions about the organ they chose, but the student can only answer with no more than five words that they think are the most important to the organ. For instance if a person researched the heart and a student asked what does your organ do the student could responds will circulatory, blood, and pumps. Some of the organ will be easy to guess but others will be harder in so few words.
