This is a review activity where students need to use their knowledge to outlive the rest of the class. Basic instructions and set-up are included for this activity. It can be used for any class and any topic that you would like to quiz your students on. The main idea of the activity is that students need to be able to describe terms, concepts, or phrases to their classmates so they can recognize what the "hidden" word/phrase is. The more the students know, the longer they can survive.
