(Grades 3-12)
| Objectives: Students should be able to: |
- Understand how the respiratory system works in humans and other organisms
- Identify different diseases of the respiratory system and their origins
- Discuss air pollution and how it affects the body through the respiratory system
Respiration:
Need for Air, O2, CO2
Respiratory System:
Anatomy
Nasal Passages
Mouth
Trachea
Bronchii
Alveolar Ducts
Alveoli
Diaphragm
Chest Wall
Ribs
Blood Vessels
Cells
Physiology
Air exchange (blood/air boundary)
Hemoglobin
Connections to cardiovascular system
Breathing:
Inspiration
Expiration
Use of muscles
Air flow
Air exchange
Pressure/Vacuum
Non-human Lungs
Fish, Reptiles, Birds, Mammals
Diving, flying
Air Pollution:
Definition
Causes
Sources: Point; Non-point
Defenses
Lung cells (immune response)
Nose
Diseases of Respiratory System: Emphysema
Asthma – allergies
Fibrosis
Obstructions – Choking, asphyxiation
Punctures – Collapsed lungs
| Materials for in-class activities: |
Diagrams/Photos of Respiratory System:
Upper body, Lungs, Airways, Alveoli
Lung model (plastic)
Lung model (working)
Dried Lungs (various animals)
Bronchial tree cast (Silastic)
Bromothymol Blue, small container, straw.
Expiratory flow meter
Public Health Literacy handout on Air Pollution
| Student In-class Activities: |
Perform breathing exercises/utilize a peak flow meter
Study lung model
View dried lungs of various animals
Examine bronchial tree preparation
Conduct bromothymol blue experiment
Follow-up activities for classroom and home:
Count breaths (resting, exercising)
Time breath holding
Continue bromothymol blue experiments
Study about lungs of different animals
Learn about gases, air pollution, and diseases
Research respiratory diseases
Design posters about the respiratory systemSelected web-sites for student/teacher use:
