Designed for middle and high school physics, this teaching tool serves as a practical aid to simulate and demonstrate the principles of mechanical transmission. Compact, desk-friendly size With dimensions of 32 cm long, 21.5 cm wide and 15.5 cm high, this gear demonstration device fits easily on a classroom desk while providing a clear view of the gear movements. Package contents Includes a mechanical gearbox model suitable for classroom demonstrations or individual study. Interactive learning experience A gear-rotation apparatus that offers students an interactive way to engage with gear movement and mechanics, enhancing understanding through hands-on learning. Key benefits - Why you need it: Visualize mechanical transmission concepts in physics class, enabling concrete understanding of gear interactions. - How it solves problems: Enables hands-on exploration, bridging theory and practice with observable gear motion in a compact, accessible form. - What makes it stand out: Specifically designed for middle and high school students, compact enough for desk use, and ready for classroom demonstrations or individual learning. Use scenarios - In-class demonstrations: Teachers illustrate gear ratios, direction and speed relationships, and overall mechanical transmission concepts with a tangible model. - Student-led exploration: Learners rotate gears, observe movement, and measure or compare gear ratios to reinforce theoretical expectations. - Learning stations or independent study: Fits into station-based activities or solo practice to reinforce concepts during or after lessons.
