This is only a suggested scheme of work and each person should adapt it to their own preferences, lesson duration and equipment. The text and building exercises have been tried by several groups of pupils and modified accordingly. The project uses mechanical, electronic and electrical systems. The inclusion of pneumatics is limited by the school facilities. The electronic and electrical modules could be used to control pneumatics if available.
Pupils can experiment with different size cogs to see the effect on speed.
The Amplification section deals with some aspects of mechanical amplification. Once the system has been created to drive a motor other mechanical movements can be explored, for example the reciprocating motion of a saw using the beam as a safety switch. This could be used to show cams. The written exercises allow teachers to assess pupil knowledge. The text also explains systems and the use of feedback.
