1. 5th Grade Health – Lungs Lesson 4 Pollution In The Community

2. Review How does the respiratory system work?
Air enters the nose where it is warmed, moistened, and cleaned
It then enters the trachea (or wind pipe). The Epiglottis prevents food for entering the trachea
The trachea branches off into the bronchi
Inside your lungs the bronchi divide into many smaller branches called a bronchiole
The tiniest bronchioles are called alveoli, which are tiny one celled air sacs which allows the transfer of Oxygen and carbon dioxide

3. What health problems can our respiratory system have?
Allergies
Bronchitis
Pneumonia
Tuberculosis
Asthma

4. What happens to your lungs when you encounter harmful things like germs, tobacco and allergens.
Increased Mucus
Narrowing of bronchi and bronchiole
Pus
Swollen membranes
Damaged alveoli
Tumors
Harmful gas exchanged instead of oxygen

5. So… What are we going to do today???
You know how the repertory system works and what happens to the lungs when they have problems
Today, we are going to look more closely at different lung problems related to the community and how we can help our community reduce the amount of lung disease
Today we are about saving lives in our community!

6. What is a community?
A community is a place where people work, live and play.

7. Since people work and live in a community, the health of their lungs often depends upon the quality of air in the community, the location of the community, the type of work done in the community, and the attitude of the people toward smoking.
All of these factors will make a community healthy or unhealthy, as far as the lungs are concerned.

8. Today you will be responsible for your own learning and for teaching others what you have learned.
I will create 4 groups
You will work with those members to read the information about community lung hazards
You will create a public service poster to educate about that hazard

9. The four groups are… Secondhand Smoke Radon Air Pollution
Workplace Lung Hazards
