1 DE Science Elementary 5-Minute Prep for Human Body Systems of the Body Digestive

2 Digestive System – The Big Ideas The digestive system breaks down food for energy and nutrients. The mouth, esophagus, stomach, small intestine and large intestine are the major parts of the digestive system. Food is chewed and mixes with saliva in the mouth which begins the process of digestion. Food and liquid travel from the mouth through the esophagus and into the stomach. Through churning and mixing with enzymes food is broken down in the stomach.

3 Digestive System – Prior Knowledge Students will have knowledge of some systems of the body prior to this study. It will be helpful for students to use the FUN-damental to review the Digestive System. It will also help if they are able to: –Explain that the body is made up of systems. –Name some parts of the human body.

4 Digestive System – Common Misconceptions Systems operate in isolation of each other. –Reality: No part of the human body works alone. Each system works in conjunction with the other parts of the body. The stomach is located at or below the belt area. –Reality: The stomach is located at the bottom of the chest just below the esophagus.

5 Digestive System – Using DE Science Content When you close this presentation, you can review the following recommended resources for the Digestive System.

7 Digestive System – Instructional Ideas Watch the Video Segment, The Digestive System. –Then, place students into groups of 4. –Each group will explain the process of digestion by sitting in a circle and taking turns naming the steps. –The first student will start and tell a sentence about the first step. –The next student will add a sentence about the next step and so on. –At the end, have a class discussion about the steps to check for the accuracy of each groups explanation.
