Scientific Evidence and Secrets of the Stomach: A Fun Lesson for Students

To uncover a secret, scientists look for evidence.  Long ago, scientists investigated to find out how the stomach works. The scientists did some surprising things.  One investigated digestion by collecting stomach juices from a man with a hole leading to his stomach! The scientists did all of these things to find evidence about how the stomach breaks down food.

In the Seeds of Science/Roots of Reading® student book Secrets of the Stomach, the work of three scientists who investigated how the stomach digests food is described.  It outlines how each of them found evidence that added to the scientific community’s understanding of digestion.  By sharing one of the investigations from this book, you can help students learn that scientists base their explanations on evidence.  After hearing the story, students learn that acid juices in the stomach aid in the digestion of food.

Students learn:

• Science investigations begin with a question.
• The stomach is a bag-like structure that holds food.
• The stomach mixes food up and breaks it down with acid.
