Chew on This

POSTED BY The Wellington School ON November 16, 2017 IN

Where does digestion begin in the human body? Just ask a Wellington 5th grader. In science class, studying the digestive system, students chewed up and spit out their findings during lab work. To test for the presence of starch in a saltine cracker, thereby determining at what point digestion begins when we eat, 5th graders chewed the food and then placed it in a baby food jar. They added iodine to both the chewed cracker as well as a “test” cracker in another jar to determine the starch level in both. Their results showed less starch in the chewed cracker, hence the process of digestion had already begun when the cracker was in their mouths. The lab gave some food for thought for the young scientists.
