This activity is great as a review tool or as a culminating activity for anatomy, physiology, or cell biology. Cells and their functions in the body are explored as well as how they interact within the organism. The basic idea for "A case of Ascaris" is a trial/investigation. Students will take on the roles of the characters which are different cells within the body of Mrs. Isabel McSweeney. Fortunately Mrs. McSweeney is out of the woods but just a few days ago she was the sickest she's ever been in her 34 years. Now the immune system is holding a hearing to decide what went wrong and how it can be prevented in the future.
