I developed question stems from the top three levels of Bloom's Taxonomy. These are generic enough that they can be used with almost any content. Then I cut them up and placed some into each of several bags. Each team was given a bag and every student was to reach in and select a question. They had a few minutes to generate a question based on our lesson, write it down on a blank strip of paper and place it into the teacher's bag.

What type of people would be on your team to solve the energy crisis?
We then randomly chose student questions to read aloud and answer. Students were highly engaged and excited to answer their peers' questions. Simple and reusable!
