This resource is suitable for KS3 or foundation GCSE.
- Describe how sound travels
- Explain the link between particles and sound moving through a medium and which medium sound can move the easiest through
- Use their knowledge to predict where and when sound waves will not travel
Key words: energy, vibrations, particles, medium, solid, liquid, gas, sound waves, squash, compress
Lesson Plan Outline
Starter Teams get 2 minutes thinking time to brainstorm what they know about sound – write one main idea on their whiteboards.
Use a Rubens Tube, speaker and beads, or tuning fork in water to explore ideas and questions.
Main: First hand experience to build concepts
Small circus of experiments
Students use a ruler on desk or an elastic band to explore how sound travel
Students put ear to desk and knock to experience how sound travels
Explain: Teacher input to formalise concept or extend
- Sound is made through vibrating air particles/pressure changes
- Particles in air, liquid and gas can all transfer sound, but particles travel quickest through solids
Elaborate: Demonstrate Learning
Students use resources to complete their hotmap and write up their description.
Extend: Apply to unfamiliar concepts
Evaluate (AfL): Pupil reflection (self or peer)
Self assess using learning log
