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). View the full activity on TeachEngineering: https://www.teachengineering.org/acti...
