In this activity, students collect real-time data using ultrasonic motion detector probes and graphing calculators. These technology tools allow for the exploration of meaningful questions that would otherwise be impossible in a typical science classroom. In addition, these tools allow students to focus their attention on the interpretation of data they collect — not its mundane and time consuming collection. The real-time graphical representations of students' motion on the graphing calculator allow them to build kinesthetic and cognitive connections between their actual physical motion and its representation on a distance v. time graph.
