Why this why now

Knowledge of how wheels and axles create movement is vital to understanding how vehicles work. This unit builds upon the Year 1 'Rotary mechanisms: windmills' unit where simple mechanisms were introduced through the use of an axle and sails. Knowledge of frame structures is introduced and will be further developed within the Year 5 'Pulleys and gears: electric vehicles' unit when they add electrical circuits, reversible switches and pulley systems.

Prior knowledge requirements

  • Pupils have assembled vehicles with moving wheels using construction kits.
  • Pupils have explored moving vehicles through play.
  • Pupils have some experience of designing, making and evaluating products for a specified user.
