Users can store several projects in the app, and use tools like an accelerometer, plus light and sound meters, in order to gather information for their projects. For example, a user could record their running pace everyday for a week, and then chart their progress on a line graph. While the number of sensors available to use is still small, Google says it will work with people in the science community to continually improve the app.
Google is also selling "hands-on learning kits" to accompany the app, which contain external sensors, microcontrollers, and other craft supplies that will help kids conduct experiments. Google says it plans to open source the app later this summer.
