In this lesson, students learn about symptoms and identifying body parts that hurt, using a video of a family as a teaching aid. The discussion centers on a child named Carlo who visits the doctor with stomach pain, suspected to be stress-induced colitis due to an upcoming exam. The doctor recommends an antispasmodic medication and a diet rich in fresh fruit, fiber, and vegetables, while advising Carlo to avoid chocolate, allowing a small treat if he does well on the exam.
