      Design specification for wheeled vehicles

      Lesson details

      Learning outcome

      I can explore a vehicle and create a design specification for a vehicle.

      Key learning points

      1. A car has a chassis, body, wheels, axles, axle holders and an engine or motor.
      2. Creating a design specification for a vehicle will help to design and make a finished product.
      3. The design specification might include - travels in a straight line, has four wheels, wheels run freely.

      Keywords

      • Axle - a rod that holds a wheel in place and allows it to turn

      • Chassis - the framework of a vehicle that supports the body and engine

      • Engine - a machine that helps a vehicle to move

      • Axel holder - the part where the axle goes through to hold it in place but still allow it to rotate

      • Design specification - describes what a product has to do

      Common misconception

      An axle must hold two wheels.

      The axle might hold one or two wheels. The axle can turn with the wheel.

      Teacher tip

      Teachers could give additional time to explore a range of vehicles and should there be an opportunity to disassemble vehicles, this could be built into the lesson. Furthermore, a range of construction kits could be used to encourage the exploration of wheels, axles, axle holders and chassis.

      Equipment

      Range of moving toys, worksheet, pencil, coloured crayons and rulers.
