A Helpful Resource for Teaching Levers in Motion in IB SEHS

This resource covers B1.4 Levers in Motion 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 levers and mechanical advantage are addressed clearly and sequentially. Teachers can follow the progression from lever theory to applied movement examples in sport, ensuring comprehensive syllabus coverage.

Helpful for New Teachers
If you are new to teaching IB SEHS, this resource provides clear and practical explanations of how levers function in the human body to create movement. It explains classes of levers, fulcrum, effort and load relationships, and how these concepts apply to performance and mechanical efficiency. Each section includes sport examples and diagrams to support lesson delivery and student understanding.

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 adapt slides, insert diagrams or videos, and tailor lessons for different groups. This makes the resource flexible for classroom teaching, blended learning, and digital environments.

Content Included

• Overview of lever systems in sport and human movement
• Definitions: fulcrum, effort, load/resistance
• First class levers: characteristics and examples
• Second class levers: characteristics and examples
• Third class levers: characteristics and examples
• Mechanical advantage and lever efficiency
• Calculations and applied examples
• Joint actions and lever function in sport movements
• Diagrams illustrating lever classes and sport examples
• Structured summaries and key terminology

The resource includes clear explanations, real world sport and exercise examples, and structured summaries that connect biomechanical theory to practical movement and performance 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.
