Check understanding
- Explain that sound vibrations need a material (medium) to travel through — they can't travel in a vacuum
- Give examples of sound travelling through different media: air, water, solid objects
- Describe how a string telephone works: voice vibrates the cup, vibrations travel along the string to the other cup
“Can your child explain why you can hear someone talking through a wall, and why sound travels through water when you're swimming underwater?”
