                                    Unit Cover Page
Unit Title: The Respiratory System           Grade Levels: 6 A
Subject/Topic Area: Gas Exchange and Dangers of Smoking
Key Words: Lungs, Bronchi, Trachea, Larynx, Mouth, Nose, Oxygen, Carbon Dioxide
Designed by: Tracy Waters                    Time Frame: Two Weeks
School District: San Jose'                   School: Blue Valley School

  Brief Summary Of Unit (including curricular contest and unit goals):
In this unit, students will learn about the functions of the respiratory system. We will link this
back to the circulatory system as we talk about the gas exhange of oxygen into the blood and
carbon dioxide from the blood. The students will design a mock lungs/diaphragm model to show
how these organs work together. They will view a real healthy and unhealthy lung from the
medical school cadavers.
In the final task, students will make an iMovie demonstrating to young children the dangers of
smoking, to teens how to avoid peer pressure and to adults on reasons to stop smoking. Some of
the iMovies will be shown during the middle and high school assemblies to impact their peers on
what they have learned.

               Stage 1 - Identify Desired Results

Established Goals
Standard 5.2- Plants and animals have structures for respiration, digestion,
waste disposal, and transport of materials.
5.2a- Students know many multicellular organisms have specialized structures
to support the transport of materials.
5.2b Students know how blood circulates through the heart chambers, lungs,
and body and how carbon dioxide (CO2) and oxygen (O2) are exchanged in the
lungs and tissues


                                     What understandings are desired?
What essential questions will be considered?
*How is the circulatory system       *The oxygen in the red blood cells
related to the respiratory system?   comes from the air we breathe.
*What affect has smoking had on our *The gases are exchanged through the
society?                             alveoli across capillaries into the red
                                     blood cells.
                                     *There are many harmful chemicals
                                     found in tobacco smoke, many of which
                                     are carcinogens.
                                     *Smoking affects more than just the
                                     smoker (ie. 2nd hand smoke, family or
                                     friend's emphysema orlung cancer).
                                     *Healthy choices, like choosing not to
                                     smoke, eating right and exercising
                                     determine our heart and lung health.
What key knowledge and skills will students acquire as a result of this unit?
Students will know …                   Students will be able to …
*Key Terms: cilia, pharynx, trachea,   *Trace the path of air through the
bronchi, lung, alveoli, diaphragm,     respiratory system
larynx, vocal cord, tar, carbon        *Explain how gases (O2 and CO2) are
monoxide, nicotine, addiction,         exchanged
bronchitis, emphysema, passive         *Describe the health risks associated
smoking                                with smoking
*Process of gas exchange               *Demonstrate ways to react to peer
(respiratory system to circulatory     pressure associated with smoking
system and back)
*Respiratory problems caused from
smoking (emphysema, asthma,
bronchitis, lung cancer)
                        Stage 2 - Determine Acceptable Evidence
