Description
Students discuss a human’s reaction time. Which is faster, seeing or hearing? They make a hypothesis and write it down.
(10 minutes)
Teacher handing out robots and worksheets. Starting a program in a robot.
Students measure their hearing response time. They start the robot and when they hear the sound, they immediately press a button. Students fill the table. (15 minutes)
