In addition to altering the app's nature, Google has also added three new sensors. So long as a phone has the appropriate hardware, students can use the app as a linear accelerometer, a magnetometer and a compass. They can even take a snapshot of their data while the tools are doing their job. To help teachers and students get started, the big G has uploaded new experiments they can do with the help of Science Journal. They can use it however they want, though, even if it's to record the sound intensity of their neighbor's Friday night parties so they can show it to the landlord.
