Northport K-8 School second grade students in Barbara Greenwood’s class used a real cow’s stomach lining called tripe, a cow’s heart and a cow’s kidney to perform inspections and learn new information about the human body. Students examined each body part and determined the functions of each organ. They understood after the in-depth lesson that the kidney removes the waste products from the body, the heart pumps and has chambers, and that the stomach lining keeps the stomach strong so it doesn’t rupture and the stomach digests foods. The hands on lesson was a real eye opener for the kids as they donned their surgical gloves and really investigated each organ critically. Pictured is Ms. Greenwood and her students.
