A Woodpecker clock invented by a 22-year-old student has replaced the annoying clangs and buzzes of traditional alarms with a gentle tapping wake-up. Children will investigate how this clock works and determine how they would change the sound.
- to generalise that when a sound is made something is vibrating.
Children will learn:
- to state that a sound has reached them by travelling through solids e.g. brick.
- to record e.g. in a table observations indicating how well sound travels through different materials.
- to generalise that sound can travel through solids.
These resources were initially developed in partnership with the Centre for Science Education, Sheffield Hallam University.
