DE Science Elementary “5-Minute Prep” ForHuman BodySystems of the Body Respiratory
Respiratory System – The Big Ideas • The respiratory system brings oxygen into the body and takes out carbon dioxide. • Air enters the body and waste gases exit the body through the nose, throat, and trachea. • When the diaphragm expands, the lungs expand and take in air. When the diaphragm contracts, the lungs release air. • The lungs expand and contract without us thinking about it. • The lungs are made of spongy tissue with a large surface area to increase contact with the air.
Respiratory 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 Respiratory System. It will also help if they are able to: • Explain that the body is made up of systems. • Identify the parts of the cardiovascular system.
Respiratory System – Common Misconceptions • The only gas we breathe out is carbon dioxide. Reality: We breathe out water as a gas in addition to carbon dioxide. • Air travels to the body like blood in air vessels. Reality: Air does not travel throughout the body in air vessels. Oxygen travels throughout the body in blood vessels.
Respiratory System – Using DE Science Content When you close this presentation, you can review the following recommended resources for the Respiratory System. • Reading Passage: A Breath of Fresh Air • Reading Passage: Lungs: Catchin’ Air • eBooks: Take a Breather • Video Segment: Breathing Use the PowerPoint version of this presentation for hyperlinks to these resources or you can get to them through the browser or search feature.
Respiratory System – Instructional Ideas • Create a K-W-L chart about breathing. • First, ask, “What do you know about breathing?” • Then ask, “What do you want to know about breathing?” • List responses to both questions on a wall chart. • Then read the reading passages, A Breath of Fresh Air, Lungs: Catchin’ Air, and Take a Breather. • Ask, “What have you learned about breathing?”, and record responses on the wall chart. • Watch the Video Segment, Breathing. • Then, ask students to use books in your school’s library to find out how different animals breathe. • Ask students to create a chart of similarities and differences comparing their findings with human respiration. • Suggestions of animals to research include: fish, birds, mammals, reptiles and amphibians.
