- Identify appropriate gear combinations for given effects (Yr5&6)
Activities
- Investigate how gears work, identify gear ratios and select possible outcomes from given gear ratios (Yr5)
- Investigate how gears work, calculate some gear ratios and suggest possible outcomes from given gear ratios (Yr6)
Investigation
Ferris Wheel: gears. The management wants a Ferris wheel ride that uses gears. Explore the options and note which gear ratios will keep the wheel moving at just the right speed. (Exploring, Problem solving, Pattern seeking, Fair testing)
Year 5 - Investigate how gears work, identify gear ratios and select possible outcomes from given gear ratios
Year 6 - Investigate how gears work, calculate some gear ratios and suggest possible outcomes from given gear ratios
