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...

This resource investigates modelling and constructing pulley systems designed to lift loads.

Suggested learning outcomes include:

• To be able to recognise and describe the main parts of a pulley system.
• To understand how a pulley system can reduce the effort needed to lift a load.
...

In this resource students are asked to test the operation of pulley systems and calculating their mechanical advantage.

Suggested learning outcomes include:

• To understand what is meant by mechanical advantage.
• To be able to calculate the mechanical advantage of pulley systems.
• ...
