Simple Machines - Gear Train

This wooden gear train model is a robust and interactive tool for exploring mechanical systems in the classroom. Built for hands-on learning, it clearly demonstrates the function and behaviour of gears in motion. As students turn one gear, they can observe the movement being transferred and direction being reversed through the series-helping them visualise abstract concepts in a tangible way. The model is carefully constructed to allow for smooth rotation and visibility of how gear teeth interlock. With clear demonstrations of drivers and followers, this gear train is perfect for exploring the fundamentals of torque, speed, and direction in mechanical engineering.

Educational benefits:

• Illustrates the basic principles of gear trains and mechanical advantage
• Helps students understand the relationship between driver and follower gears
• Encourages analytical thinking through observation of gear rotation and direction
• Reinforces concepts of motion transfer, force distribution, and energy efficiency

Classroom activity ideas:

• Let students experiment with gear direction and predict rotational outcomes
• Demonstrate how gears are used in clocks, bicycles, and machinery
• Explore the ratio of teeth between gears and its effect on speed
• Use as a base for STEM challenges where students design gear-based contraptions
