5. Mechanisms Cam Bell crank Quick return There are many more, but the cam is the one we are going to concentrate on. Cam challenge!

6. Your toy Have a look at these toys – can you work out how they move? Discuss with a friend.these 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.here Share ideas as a class. NEXT

7. BACK

8. How it’s done! Back

9. 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.

10. 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
