  1. DE Science Elementary “5-Minute Prep” forHuman BodySystems of the BodyExcretory System

  2. Excretory System – The Big Ideas • The excretory system rids the body of waste products. • The large intestine, kidneys, bladder, and skin are the major parts of the excretory system. • The small intestine absorbs food nutrients. • The kidneys filter liquid in the body and excrete waste through the bladder and skin.

  3. Excretory System – Prior Knowledge Students will have knowledge of some systems of the body prior to this study. It will help for students to use the FUN-damental to review the Excretory 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. • Name the steps of the digestive process.

  4. Excretory System – Common Misconception • All liquid waste is excreted by the urinary system. • Reality: The body gets rid of liquid waste through sweating, breathing, and urination. It gets rid of solid waste through excretion. • Everything goes into one big container inside the abdomen, then some of it comes out. • Reality: The digestive and excretory process is very complex staring with digestion in the mouth, a different digestion in the stomach, and still more digestion in the small and large intestines.

  5. Excretory System – Using DE Science Content When you close this presentation, you can review the following recommended resources for the Excretory System. • Reading Passage: Gotta Go! • Reading Passage: Taking Out the Garbage • eBook: Your Brain: Keeping Connected • Video Segment: The Excretory System Use the PowerPoint version of this presentation for hyperlinks to these resources or you can get to them through the browser or search feature.

  6. Excretory System – Instructional Ideas • Place students into groups of three. • Assign each student to read one of the reading passages. • Then, ask group members to compare how their articles are similar and different by creating a chart on paper. • Finally, lead a class discussion about the similarities and differences. • How long is the small intestine? • Ask students this question and record their suggestions together somewhere visible. • Then, watch the video segment, Small Intestine. • At the end, show students a piece of yarn, string or a tape measure measured between 16-19 feet and compare this with the students’ suggestions. • Discuss the function of the small intestine.
