Gamified physics challenges for teachers and the public

This article describes the development and deployment of Physics Toolbox Play, a gamified component of the Android Physics Toolbox Sensor Suite app, that can introduce young children through adults to fundamental physics principles. The app was used successfully in a variety of contexts, including STEM fairs with primary and secondary students and workshops with undergraduate physics majors and practicing teachers. Anecdotes from our experiences suggest that smartphones are an effective way to introduce learners to the big ideas and big principles in physics.
