Learners will investigate sound in the environment and test how properties of sound change (pitch and intensity) (a later-grade match).
The Nova Scotia Science curriculum outcome (Physical Science: Sound) for Grade 4 says: “Learners will investigate sound in the environment and test how properties of sound change (pitch and intensity) (a later-grade match).” This Fieldbook unit teaches it hands-on, with everyday materials and a printable teacher guide and student sheet for every lesson. Official wording: Nova Scotia Science curriculum.
Sound: Can You See a Sound? Grades K–2
Can you see a sound? Young scientists make rice dance on a drum, talk through a string telephone and build a rubber-band guitar to find out that every sound starts with something shaking.
- Can you see a sound? 40–45 min
Children make grains of rice jump on a plastic-wrap drum, pluck rubber bands on a box and twang rulers on the edge of a table. They find out that every sound they make comes from something shaking back and forth very fast.
- Can a string carry your voice? 45 min
Children build cup-and-string telephones and test them with the string tight, loose and pinched, then compare different kinds of string. They find out that a tight string carries the shake of their voice from one cup to the other.
- How do you make a high note or a low note? 45 min
Children build a rubber-band guitar with thick and thin bands and blow across plastic bottles holding different amounts of water. They find out that fast shaking makes a high note and slow shaking makes a low note.
