| Description | Students learn the physics of sound and how it travels, as well as how noise impacts human health. Then they devise an experimental procedure and teams collect data in their classroom, school and near a loud noise source (such as a busy road or construction site) using smart phones/tablets, microphones and noise apps. They calculate wave properties, including frequency, wavelength and amplitude. Students learn the physical properties of sound, how it travels and how noise impacts human health—including the quality of student learning. They learn different techniques that engineers use in industry to monitor noise level exposure and then put their knowledge to work by using a smart phone noise meter app to measure the noise level at an area of interest, such as busy roadways near the school. They devise an experimental procedure to measure sound levels in their classroom, at the source of loud noise (such as a busy road or construction site), and in between. Teams collect data using smart phones/tablets, microphones and noise apps. They calculate wave properties, including frequency, wavelength and amplitude. A PowerPoint® presentation, three worksheets and a quiz are provided. |
