Students investigate sound in their environment, particularly how sounds impact their lives. At the beginning of the unit, students use online simulations to investigate the properties of sound and learn about the components of a sound wave. They identify the different sounds in their environment and place them into categories for analysis. Students complete a project where they develop a research question, collect data in the field about different sounds, and analyze their data. They use what they have learned to create a digital product that makes recommendations about teens and sound. At the end of the unit, students share their products and take an exam over the science content.
