Do you like Grey's Anatomy or Scrubs? Engage your students by having them write up a case study like the ones they would see on shows like these. Students first would conduct research on a disease. In this case, the focus is on organelles, but you can adapt it to any disease of the human body. Students would then create a case study to help further develop their writing skills as well as deepen their understanding of various diseases.
If you're like me, you will need scaffolding for a written assignment of this type. I provide you with a research graphic organizer as well as a way for students to outline their thoughts before producing the written case study. Sample answer key included.
