Introduction  

Can you move as smoothly and silently as a ninja? In this experiment, you will use your stealthy ninja skills to move through a noisy obstacle course while holding a smartphone that is recording data on your performance. The challenge is to navigate this noisy course with a steady, quiet pace that doesn’t cause your phone’s sound sensor or accelerometer to spike.  This fun activity can get your whole family up and moving while analyzing data!
