Subject: Science
Grade Level: Grade 9
Objective:
1. Determine what the respiratory system is.
2. Identify the parts and functions of the respiratory system.
3. Cite examples on how to take care of the respiratory system.
Learning across the curriculum:
- English Language: Write a short essay explaining the importance of the respiratory system
in maintaining overall health.
- Physical Education: Discuss the connection between physical activity and respiratory
health.
- Home Economics: Prepare a healthy meal plan that promotes respiratory health.
Elicit:
- Ask students if they have any idea what the respiratory system is and translate this to
English.
Engage:
1. Show a short video clip about the respiratory system and ask students to write down three
things they learned from it.
2. Conduct a quick class discussion about the importance of breathing and how it relates to
the respiratory system.
3. Display images of different organs involved in the respiratory system and ask students to
identify each organ.
Explore:
Activity 1: Respiratory System Organ Matching Game
Materials: Flashcards with the names of respiratory system organs
Instructions: Distribute the flashcards to students and have them match the organ
names with their corresponding images. Use a rubric to assess their accuracy and give
points accordingly.
Assessment Questions:
1. What is the main organ responsible for the exchange of oxygen and carbon dioxide in the
respiratory system?
2. Name one function of the diaphragm in the respiratory system.
Activity 2: Respiratory System Diagram Analysis
Materials: Respiratory system diagrams, markers
Instructions: Provide each student with a respiratory system diagram and ask them to
label the different parts and write a brief description of their functions. Use a rubric to
assess their accuracy and give points accordingly.
Assessment Questions:
1. What is the function of the trachea in the respiratory system?
2. Name one part of the respiratory system that helps filter out dust and other particles from
the air.
Activity 3: Respiratory System Health Poster Creation
Materials: Art supplies, poster board
Instructions: Divide students into groups and assign each group a specific aspect of
respiratory system health (e.g., avoiding smoking, regular exercise). Have them create a
poster that promotes and educates about their assigned aspect. Use a rubric to assess
their creativity, accuracy, and presentation.
Assessment Questions:
1. What are the main components of a healthy respiratory system?
2. How can regular exercise contribute to maintaining a healthy respiratory system?
Explain:
1. Teacher-led lecture: Explain the different parts of the respiratory system and their
functions, using visual aids and diagrams.
2. Interactive discussion: Engage students in a discussion about the importance of taking care
of the respiratory system and how it can affect overall health.
Elaborate:
1. Role-play: Divide students into pairs and have them act out a scenario where one person is
experiencing difficulty breathing and the other acts as first responder providing assistance.
2. Case study analysis: Provide students with case studies of individuals with respiratory
system disorders and ask them to analyze the causes, symptoms, and possible treatments.
Evaluate:
1. Quiz: Create a short quiz consisting of multiple-choice and fill-in-the-blank questions to
assess students' understanding of the respiratory system and its functions.
2. Group presentation: Have each group present their respiratory system health posters and
evaluate their presentation skills, accuracy of information, and creativity.
Extend:
- Invite a respiratory therapist or a medical professional to speak to the students about the
importance of respiratory health.
- Organize a field trip to a local hospital or clinic to observe respiratory system examinations
or treatments.
Assignment:
Write a short essay on the importance of maintaining a healthy respiratory system and the
steps one can take to achieve this.
