Use tools and materials to design and build a device to understand that light and sound travel in waves and can send signals over a distance.
The Tennessee Academic Standards for Science (2022) outcome 2.PS4.2 (Physical Sciences) for Grade 2 says: “Use tools and materials to design and build a device to understand that light and sound travel in waves and can send signals over a distance.” This Fieldbook unit teaches it hands-on, with everyday materials and a printable teacher guide and student sheet for every lesson. Official wording: Tennessee Academic Standards for Science (2022).
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 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.
