Gear Ratio Guided Investigation Interactive
Follow a scaffolded investigation of gear trains, gear ratios and mechanical advantage. Students apply speed, direction and torque reasoning to a design challenge. The full interactive is available to licensed Education Universe users.
Years 8–10Guided investigationGears
Learning outcomes
- Calculate and interpret gear ratios
- Compare idler and driven gear functions
- Evaluate gear arrangements against a design brief
Teaching guidance
Have students sketch the proposed train and verify whether the tooth-count constraints make the desired ratio possible.
