Nine pages for the sound half of Ontario’s Grade 4 light and sound energy topic. Students learn that every sound starts with a vibration, that sound needs a medium to travel through, and why it travels faster in water and steel than in air. They find out what changes pitch and loudness, and test which materials absorb sound best.
Canadian examples run through it: counting the seconds between lightning and thunder, beluga whales and little brown bats that find their way by echo, and loud places where hearing protection matters. Teacher notes, a quiz and a full answer key are included.
