• Tounderstand that a cam will change rotary motion into linearmotion
• Understandthat different shaped cams produce different movements
• About therelationship between a cam and a follower

Investigatea collection of moving toys that contain a cam mechanism

Question Which parts turn? Which parts move? How are the different partsattached to allow free movement?

Look inmore detail at the moving part of the toy

2

• Tomeasure and mark accurately
• To usetools for cutting safely and effectively
• To use adrill to make an off centre hole in a wheel

Show amodel of a cam mechanism and allow them to put together the partsas a practice. Ask them to try out different shaped cams andobserve movement.
