Modelling linkages

Investigating simple linkages using card models.

A mechanism is a device that changes movement in some way. Linkages are a type of mechanism. There are different types of linkage, each of which change movement in different ways.

This could be used in Key Stage 2 as a stand-alone activity or as an introduction to a design and make project, such as:

  • A greetings card - for example a ‘goodbye’ card with a hand that waves.
  • A moving poster or display.
  • A ‘grabber’ to pick things up.

In this activity, students will make models of simple linkages from card.
