Unit Two

Looking at energy, materials, systems and devices

Unit Two
By the end of the unit, you will all be able to:

  • Explain how power is generated from oil, gas, coal and nuclear sources
  • Explain how renewable energy is generated from a variety of sources
  • Describe kinetic pumped storage systems
  • Name and define a range of modern, smart and composite materials
  • Understand the unique properties of technical textiles
  • Describe the benefits of microencapsulation
  • Recognise and describe a range of input and output components, physically and symbolically
  • Understand that all systems comprise of one or more inputs, processes and outputs
  • Recognise different types of mechanical movement
  • State examples of first, second and third order levers
  • Understand how linkages change the direction of movement
  • Recognise different types of cams and followers
  • Understand that pulleys can change the magnitude of force required to lift mass

To be secure in your learning, you should also be able to:

  • Argue for and against the selection of fossil fuels or nuclear power
  • Argue for and against the selection of renewable energy
  • Explain the difference between alkaline and rechargeable batteries
  • Justify where the use of a technical textile might be suitable
  • Suggest a suitable input or output device for a given scenario
  • Suggest a suitable linkage for a given scenario
  • Understand how the action of forces, levers and gears transmit and transform the effects of forces

To achieve the higher grades you should also be able to:

  • Justify the use of a range of modern, smart and composite materials for given situations
  • Suggest an appropriate movement and mechanism to use in a given scenario to perform a specific task
  • Demonstrate an understanding of how microcontrollers are programmed to control processes in simple systems
