Different types of movement • Linear – • Reciprocating – • Rotary - • Oscillating - • Intermittent – • Irregular -
What parts move? • Have a close look at some of the moving toys in the classroom. • Which parts turn? • Which parts move? • Can you see or work out how the parts are attached? • Pick one toy and draw and label it.
How does it move? • Toys move because they have mechanisms. • There are different types of mechanisms that allow different movements. • Click here to see the different types of mechanisms.
Mechanisms • Cam • Bell crank • Quick return • There are many more, but the cam is the one we are going to concentrate on. • Cam challenge!
Your toy • Have a look at these toys – can you work out how they move? Discuss with a friend. • Use a design sheet to think about who you would like to make a toy for and some ideas for your toy. Click here to see a really good example of a toy design. • Share ideas as a class. NEXT
How it’s done! Back
Make a mechanism • Now you have decided what toy to make, you need to practice making your mechanism. • Make a card model of your mechanism. • When you have done that, complete design sheet 3 where you will finalise your design.
Planning • Planning is very important. • Use design sheet 4 to list the items you will need. • Complete the flow diagram to show the order in which you will make your toy. HAVE FUN
