Description	Students learn about how sound sensors work, reinforcing their similarities to the human sense of hearing. They look at the hearing process—sound waves converted to electrical signals sent to the brain—through human ear anatomy as well as sound sensors. Students learn about how sound sensors work, reinforcing their similarities to the human sense of hearing. They look at the hearing process—sound waves converted to electrical signals sent to the brain—through human ear anatomy as well as sound sensors. A mini-activity, which uses LEGO® MINDSTORMS® NXT intelligent bricks and sound sensors gives students a chance to experiment with the sound sensors in preparation for the associated activity involving the sound sensors and taskbots. A PowerPoint® presentation explains stimulus-to-response pathways, sensor fundamentals, the unit of decibels, and details about the LEGO sound sensor, including how readings are displayed and its three modes of programming sound input. Students take pre/post quizzes and watch a short online video. This lesson and its associated activity enable students to appreciate how robots can take sensor input and use it to make decisions to via programming.
