Full lesson	Create for a teacher a set of content for giving a lesson, beginning with the lesson plan. Each new block of materials must begin with an H1 heading (other subheaders must be H2, H3, etc). When you describe required pictures, write those descriptions in curly brackets, for example: {A picture of a triangle}

Lesson plan

Topic

Oxygen Saturation

Objectives

• Understand the concept of oxygen saturation.
• Learn how to measure oxygen saturation levels.
• Identify factors that can affect oxygen saturation.
• Discuss the implications of abnormal oxygen saturation levels on health.

Materials

• Pulse oximeters (enough for small groups)
• Whiteboard and markers
• Printed fact sheets on oxygen saturation
• Projector and screen for visuals
• Internet access for research

Grade/Age Group

Adult courses

Subject

Science

Class Size

20 students

National Curriculum Alignment

This lesson aligns with the Australian Curriculum, specifically the Biological Sciences and Health Strand, focusing on the human body's processes and functions.

Lesson Structure

Step Number	Step Title	Length	Details
1	Introduction	5 mins	Introduce the topic, explain the importance of oxygen saturation in the body. Present an overview of the lesson objectives.
2	Theory Overview	10 mins	Discuss what oxygen saturation is, how it is measured, and the significance of normal ranges (95-100%). Use visuals to enhance understanding.
3	Group Activity	8 mins	Divide students into small groups. Each group uses pulse oximeters to measure their own oxygen saturation and discuss their findings.
4	Factors Affecting Levels	5 mins	Engage the class in a discussion about factors that can affect oxygen saturation (e.g., altitude, health conditions, exercise).
5	Implications of Abnormal Levels	5 mins	Discuss the health implications of abnormal oxygen saturation levels and why monitoring is vital, particularly in clinical settings.
6	Conclusion and Q&A	2 mins	Summarize key points from the lesson. Open the floor to any questions.

Homework

• Students are to read a provided article on the effects of oxygen saturation on physical performance and write a short reflection (200-300 words) on the findings.
• Submit reflections electronically by the next class. Homework will be checked for understanding and completeness but will not be presented in front of the class.

Assessment

• Participation in group activities.
• Completion of homework assignment.

Notes

• Ensure all students are comfortable using technology (pulse oximeters).
• Provide support for students who may have difficulty understanding technical terms.
• Consider addressing any specific inquiries related to health implications based on students' backgrounds.
