A Helpful Resource for Teaching Maintaining Homeostasis in IB SEHS

This resource covers A1.2 Maintaining Homeostasis from the IB Diploma Programme Sports, Exercise and Health Science course. It is designed to serve two purposes: as supplemental companion notes for instructors and as structured revision material for students.

What Makes This Resource Useful for SEHS Teachers

Follows the Subject Guide Directly
The content is structured in alignment with the IB SEHS subject guide, ensuring that all required assessment statements related to maintaining homeostasis are addressed in sequence. Teachers can follow the progression from the concept of internal balance to specific physiological control mechanisms during rest and exercise, ensuring complete syllabus coverage.

Helpful for New Teachers
If you are new to teaching IB SEHS, this resource provides a clear and practical overview of how the body maintains stable internal conditions. It explains feedback systems, control centres, effectors, and physiological responses to exercise and environmental stress. Each section includes clear explanations, structured notes, and sport-related examples designed to support effective lesson delivery.

Designed for Dual Use
This resource serves as both a reference for instructors and a revision guide for students. Teachers can use it as structured companion notes, while students can use the same material for independent review and exam preparation.

Editable PowerPoint Version Included

In addition to the printable PDF version, this resource includes an editable PowerPoint presentation that mirrors the full content. Teachers can modify slides, add diagrams or media, and adapt lessons for different groups. This makes the resource flexible for classroom teaching, blended learning, and digital environments.

Content Included

• Definitions and explanations of homeostasis
• Negative and positive feedback mechanisms
• Control systems: sensors, control centres, effectors
• Thermoregulation and temperature control
• Blood glucose regulation and energy balance
• Fluid and electrolyte balance principles
• Respiratory and cardiovascular adjustments during exercise
• Neural and hormonal coordination of homeostasis
• Responses to acute and chronic exercise stress
• Sport and exercise-based examples
• Key terminology and structured summaries

The resource includes clear explanations, real world sport examples, and structured summaries that connect physiological theory to practical contexts.

This is a straightforward and accessible resource for both teaching and revision; detailed enough to guide lesson delivery and balanced for students preparing confidently for IB SEHS assessments.
