Quadcopters, or drones, have come into wide use recently for a variety of applications including video inspection of otherwise inaccessible areas, real estate sales, and entertainment. Students are interested in them and in some cases own their own. The combination of high mobility, relatively low price, and autonomous operation is quite…

We measure the vertical velocities of elevators, pedestrians climbing stairs, and drones (flying unmanned aerial vehicles), by means of smartphone pressure sensors. The barometric pressure obtained with the smartphone is related to the altitude of the device via the hydrostatic approximation. From the altitude values, vertical velocities are…

The incorporation of scientific inquiry into college classrooms has steadily risen as faculty work to move away from exclusively didactic methods. One type of inquiry structure, the design task, produces a product rather than simply a conclusion. This offers students a context to apply their understanding of content in a tangible way that has…

Several teachers from State College (Pennsylvania) Area School District became intrigued with helping their students better understand the science associated with a unit on air and aviation. In particular, they observed that students often encountered difficulty with abstract flight concepts, such as lift, thrust, and drag. Content issues became…

The current paradigm in science education calls for greater emphasis on guiding students in active and extended scientific inquiry. This is supported by research suggesting that using a hands-on approach to learning fosters ownership in the learning process and allows students to gain greater appreciation for the design and implementation of…
