  • Begin with Video-assisted Learning to help build background and knowledge about what are waves in physics.
  • Learn and Practice: Wave on a string to observe a string vibrate in slow motion. Identifying the characteristics of transverse and longitudinal waves.
  • Practice: Distinguish between electromagnetic and mechanical waves.
  • Practice: Listening to the sound and write down the right features and drag the corresponding waveform. Determine what sound it is.
  • Play Snakes and Ladders Game to practice what you learned today.
