Schemes of Work

4P
- 4P.1
  - Overview
    - T: Key Learning points:
      
      - Waves transfer energy from one place to another.
      
      - When a object absorbs a wave it gains energy.
      
      - The gained energy will either make it hotter or make it vibrate.
      
      DESIRABLE:
      - The amount of energy absorbed is affected by the frequency of wave.
  - Lesson 01 - What is a wave? Lesson Plan Lesson Title

    - W: When the energy is increased the displacement from equilibrium point will increase. - KS3.P.29
    - T: The maximum displacement is called the amplitude. - KS3.P.29
    - T: The highest points of a (transverse) wave are known as peaks, the lowest points are called troughs. - KS3.P.29
    - T: The distance between like places on a wave, such as peak-to-peak or trough-to-trough, is known as the wavelengths. Wavelength is measured in metres (m). - KS3.P.29
