Respiration System

  1. 1. 8th Grade Life Science By: Kristen Smith Lesson Plan: 40 minutes One Class Standards: Performance Indicator 1.2 1.2a Each system is composed of organs and tissues which perform specific functions and interact with each other, e.g., digestion, gas exchange, excretion, circulation, locomotion, control, coordination, reproduction, and protection from disease. 1.2b Tissues, organs, and organ systems help to provide all cells with nutrients, oxygen, and waste removal. 1.2c The respiratory system consists of organs that are responsible for the exchange of materials involving oxygen and carbon dioxide. Objective: Students will be able to: - locate essential organs in the human body - arrange placement of organs in the human body - define essential organs. Ex: trachea, lung, diaphragm Method/Teaching Strategy: The teacher will present a PowerPoint on the respiratory system. It will go over all the essential organs and discuss the properties of structure and function. Students will take outlined notes that will follow along with the PowerPoint. Materials: - PowerPoint projector - outlined notes
  2. 2. 8th Grade Life Science Did you know? Hiccups are the sudden movements of the diaphragm. It is involuntary --- you have no control over hiccups, as you well know. There are many causes of hiccups. The diaphragm may get irritated, you may have eaten to fast, or maybe some substance in the blood could even have brought on the hiccups. Procedure: The teacher will begin the unit on the respiratory system. Students will receive outlined notes, and they will fill in note sheets while listening to a PowerPoint presentation on the respiratory system. (30 minutes) B. Respiration and Breathing RESPIRATION 1. ________________________ - oxygen and glucose undergo a series of chemical reactions inside cells. These chemical reactions release energy and produce carbon dioxide. BREATHING 2. ______________________ - movement of air into and out of lungs - Student will be encouraged to ask questions and have open discussions about the structure and function about various respiratory organs. - Teacher will show brief video clips along with PowerPoint to highlight core concepts. - With remaining class time, use an online fetal pig model to show students the key organs. Fetal Pig Dissection - If time permits show students 3-D approach using in class anatomy model (SHIM).
  3. 3. 8th Grade Life Science Assessment: Assessment will be taken via ”teacher watching” and see how students react to questions posed as well as questions asked. Worksheets will be given later in the unit as well as a unit it. Assessment can also be taken depending on student participation in the “amnesia” game which will occur as a review later on. Rationale: The respiratory system is a key component when studying the human body in 8th grade Life Science. Students need to know how essential organs are able to act in terms on gas exchange to carry out specific life functions and maintain the organism’s homeostasis.
