Improvements to the “Ishi-tsuri Bune” Model Teaching Aid for Learning Buoyancy: Enhancing the Boats’ Stability and the Tests’ Reproducibility

Key Points

• This research aims to improve the Ishi-tsuri Bune model aid for teaching buoyancy concepts effectively.
• Developed an improved Ishi-tsuri Bune model teaching aid.
• Replaced the foam tray with a circular petri dish for enhanced stability.
• Conducted tests with stones placed above and below the model to verify results.
• Both test conditions (stones above and below) aligned with theoretical predictions.
• Improvements confirmed the usefulness of the model as a teaching aid.
