This resource for teachers highlights Jerry Palotta's "Who Would Win?" book series as a mentor text for a Project Based Learning Unit. It includes an example from a World History class in which early humans are compared in a who would win scenario. You will also have templates and rubrics that will apply to a comparative analysis project in Literature, Science and History, as well as ideas to get you started in each of these studies. Explanations for what PBL is and reflective questions to analyze your project to see if it meets PBL criteria are included as well.
