Can You Hear Me Now? Designing a Communication Device

Can you communicate without electricity? In this activity, students explore a problem in which a school’s power has gone out and they need to deliver an important message to a neighboring first grade classroom. However, they must stay within the following constraints: they cannot use cell phones and they have to stay in their classroom while doing so. Students research and use a variety of tools and materials to build, test, and retest a device that communicates sound the most clearly while learning about and demonstrating how sound causes vibrations.
This engineering curriculum aligns to Next Generation Science Standards (NGSS).
