Rotary motion

Using wind

Testing wind sails

Select materials for wind sails

Selecting an axle for a windmill

Finishing and testing windmill mechanisms

Presenting final designs

This unit introduces knowledge of simple rotary mechanisms that create movement. Pupils will investigate how windmills work, consider sail design, and produce a working model that will be tested for stability and movement.
