The traditional Run the Football Field physics activity--in which students are timed as they move at different speeds on a football field to investigate displacement and velocity--has been updated for the 21st century. Nowadays, GPS-enabled tablets and smartphones replace the stopwatches and yard markers of the past, allowing students to collect real data and learn about the concepts of motion. This article describes a two-day lesson in which students use a free Android app called Data Walk to log their positions over time. Students upload the app's data output to a web platform called the Internet System for Network Science Experimentation (iSENSE), allowing them to view their motion in pictures and numbers. Visual representations and accurate position-time data enhance student learning and improve the outcome of the traditional run-the-field activity. The author calls this updated lesson the "Human Ticker Tape" lab because the data resemble the carbon paper dots of traditional motion labs.
