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.
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.

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.Small Intestine –At the end, show students a piece of yarn, string or a tape measure measured between feet and compare this with the students suggestions. –Discuss the function of the small intestine.
