Introduction  

What do folding chairs, scissors, window hinges and puppets have in common? They all use linkages! Linkages are a group of parts connected by hinges that allow each part to rotate and move. Some linkages, like scissors, are simple, while others can be more complex, like the mechanical characters in amusement parks. This activity is an open-ended exploration of linkages and the types of motion they can create.

Design Challenge

Design a whimsical creature using cardboard linkages. 

 

Try to create surprising movements (think flapping wings, dancing robots, 

and chomping sharks).
