  1. The Human Respiratory System Mrs. Lucas 8th Grade Science Nikki Lucas University of Phoenix CMP 555 – Designing and Producing Educational Technology Thomas Kelly March 2, 2009

  2. Introduction This unit of study is meant to increase your awareness of the human respiratory system, its major parts, and the functions of these parts. Upon successful completion of this unit, we will move into study of the circulatory system and explore how this system works alongside of the respiratory system to promote human health and well-being.

  3. Your objective is… • In this activity, you will learn the parts of the human respiratory system along with their corresponding functions.

  4. Overview:Major Parts of the Respiratory System • Nasal Passage • Pharynx • Larynx • Trachea • Epiglottis • Bronchial Tubes • Bronchioles • Alveoli • Lungs • Diaphragm

  5. Individual Work: KWL chart regarding the respiratory system. Labeled diagram of human respiratory system. Manipulation of human body model to properly place respiratory system parts. Answer teacher questions regarding human respiratory system. Group Work: Worksheet booklet identifying parts of respiratory system and related systems, along with corresponding quiz. Access interactive websites that help in learning the parts of the human respiratory system. Construct a Word report or PowerPoint presentation addressing one disorder of the human respiratory system. Reports will be presented to the class. Directions:The following is a breakdown of individual and group work you will complete during this unit of study:

  6. KWL ProcessGetting Started… • Before beginning instruction, begin your KWL chart provided by the instructor. Fill in the following: • K: What do you already know about the human respiratory system? • W: What do you want to learn about the human respiratory system?

  7. Let’s move forward… • Take out your respiratory system booklet handouts. • With your partner, read through the information provided in the booklet, and complete the corresponding activities and quiz at the end. • Once you have finished, see me for feedback on your completed booklet.

  8. Notes:The roles of the respiratory system parts: • Nasal Passage: The “nose”, this is the opening to the system. • Pharynx: The “throat”, air initially passes through this structure between the nasal passage and trachea. • Larynx: The “voice box”, this is where vocal chords produce sound waves (our voice). • Trachea: The “windpipe”, this is the muscular tube where air passes after it leaves the pharynx and moves to the bronchial tubes. • Epiglottis: The flap of tissue covering the openings to the trachea and esophagus – it only opens one passageway at a time to prevent choking.

  9. Notes cont’d: • Bronchial Tubes: These two tubes branch from the bottom of the trachea and carry air into the lungs. • Bronchioles: These small tubes branch from the ends of the bronchial tubes and spread throughout the lungs – they lead to alveoli. • Alveoli: These are small air sacs that have extremely thin and porous walls that are conducive to gas exchange of carbon dioxide and oxygen. • Lungs: These are the major organs of the circulatory system, the site of major gas exchange. They expand to allow for movement of gases in and out of the body. • Diaphragm: This muscle is located below the lungs and contracts and expands to control the amount of air exiting and entering the lungs.

  10. We are now going to enter the computer lab, where you will work with a partner at your own computer terminal. • Once in the computer lab, you will be viewing the following sites: • The Labeled Respiratory System • • Kids Health for Kids: Your Lungs and Respiratory System • • E-Learning for Kids: The Respiratory System •

  11. While in the lab: • 1. Access the first site, with the labeled respiratory system. Check your own diagram worksheet and make certain your labels are correct. • 2. Access the second site. This site provides audio and video – which we will view together using the SyncronEyes technology. • 3. Using the videos regarding the respiratory system, write one additional piece of information regarding each system part into your graphic organizer used during notes. • DO NOT HESITATE TO ASK QUESITONS IF YOU NEED HELP!!

  12. Go to • Search for respiratory system disorders or diseases. • Complete either a one page typewritten report (double spacing, size twelve font, one inch margins all around) or a PowerPoint presentation (minimum of 5-8 slides) summarizing the definition, causes, symptoms, and treatments or cures for this disorder/disease. • You and your partner will report back to the class on your chosen disease.

  13. Enrichment Activities • Using balloons provided by your instructor, work with your partner to make a model of the respiratory system and demonstrate how the movement of the lungs is similar to that of a balloon. • You will also complete the crossword puzzle provided in class to review vocabulary of respiratory system and learn some additional terms associated with this system.

  14. Going back to the KWL… • Revisit your KWL chart and complete the “L” section. • L: This stands for what you have learned regarding the respiratory system that you did not already know before studying this unit.

  15. Evaluation Process • You will be evaluated individually by your teacher on all aspects of this unit using the rubric established before instruction began.
