This lesson presents a comprehensive overview of diabetes, including the causes of—as well as the biological processes leading to—this widespread disease. Students will learn about the symptoms of diabetes and will become knowledgeable about healthy behaviors that can lead to the prevention of the disease. They will also become informed about normal and abnormal blood sugar percentages. Students taking this lesson should have some familiarity with the workings of the Endocrine system, the Parathyroid glands and the Pancreatic gland. During breaks, students will work with the KWL table strategy, will engage in small group discussion on several critical factors related to diabetes, and at the end, will be asked to design a logo, a poster or a flyer to provide advice and help to people in avoiding diabetes.
