a Pathway to Success

Electrical / Control

Year Four

  • simple safety when using electricity  

  • that torches are designed with the particular needs of the user in mind and that these needs can vary widely  

  • that commercially available torches contain a simple circuit involving metal connectors which do not necessarily have to be wires  

  • that torches are made of a variety of materials suited to the purpose for which they are employed

  • how to make a simple circuit incorporating a battery, light bulb, switch and connecting wires in a safe manner  

  • how to find a fault in a simple circuit and correct it  

  • that a variety of metals in different forms will conduct electricity

  • that identification of a particular combination of needs can result in a design for a torch which has not existed before  

  • that the plans for a new product can be made using drawings with labels  

  • to check their product is safe  

  • to evaluate their work both during and at the end of the assignment  

Year Five

  • that there are a variety of products which incorporate a pulley and a drive belt and are driven by a motor or a computer  

  • how control systems are used in everyday life  

  • the appropriate vocabulary related to control systems  

  • that they can model their ideas for their own product using mechanisms, by using construction kits or making a model from a set of instructions  

  • how to include an electric motor in a simple circuit  

  • how the direction of rotation and speed of an electric motor can be controlled  

  • how rotation can be transferred from one part of a model to another by using pulleys and a belt  

  • how a belt and pulley system can reverse the direction of rotation (by twisting the belt through 180 degrees)  

  • how a belt and pulley system can turn the plane of rotation through 90 degrees (by twisting the belt through 90 degrees)  

  • how a belt and pulley system can increase or decrease the speed of rotation (by using different size pulleys)  

  • to make decisions with regard to the type of ride they will make  

  • to model their intended fairground ride  

  • to make modifications as they go along  

  • to evaluate against their original criteria and suggest ways that their ride could be improved  

Year Six

  • how a vehicle moves using wheels and axles  

  • to investigate and disassemble products in order to learn how they work and how they are made  

  • to communicate through labelled drawings  

  • that there are different sorts of switches

  • to assemble components to make working models  

  • how to control the speed and direction of movement using pulleys and/or gears  

  • how electrical circuits with switches can be used to achieve functional results  

  • to use tools safely and accurately  

  • to generate and model ideas through discussion and drawing  

  • to design and make as part of a team  

  • to select appropriate tools, materials, components and techniques  

  • to plan the main stages of making  

  • to evaluate their work according to their design criteria and to suggest improvements
