Designing a Sound Reducing Wall

Science and Children, v53 n1 p52-59 Sep 2015
Acoustical engineers use their knowledge of sound to design quiet environments (e.g., classrooms and libraries) as well as to design environments that are supposed to be loud (e.g., concert halls and football stadiums). They also design sound barriers, such as the walls along busy roadways that decrease the traffic noise heard by people in neighboring houses. To help students better understand sound in a fun and engaging way, the authors conducted an engineering design-based science learning activity that is appropriate for a one-hour time block in a third- or fourth-grade classroom. In this activity, student teams were challenged to design, construct, and test a sound-reducing wall created from common classroom materials. This article provides a lesson overview, describes the engineering design challenge, and how the teachers performed assessments of the students' work.
