This activity allowed students to show the process of meiosis. However, this can be done with any process that involves movement. You can see some of the videos that My student's created. One issue is that there is a lot of time required to set up, and also time for the students to put their projects together. imovie was the software we used to put these together.
Other ideas in my class, moon phases, mitosis, growth of plants/animals etc.
