a list which helps to see if the object does what it is expected to do

checking how good something is and how to make it better

Finishing and testing windmill mechanisms

Design and technology

Rotary motion

Using wind

Testing wind sails

Select materials for wind sails

Selecting an axle for a windmill

Make a windmill

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.

Rotary mechanisms: windmills

Physical activity and equipment requiring safe use

Use of equipment that may require supervision for safety, e.g. scissors in KS1, needles, paint, knives, cooking.
