The Google Science Journal is a digital science notebook that provides users with one location to store notes, photos, and observations. It works with Android devices, iPhones, iPads, and Chromebooks.

The Google Science Journal allows users to conduct experiments involving light, motion, sound, and air pressure using sensors that are already built into the phone. External sensors can be used to connect to several Bluetooth-enabled devices from Arduino and Vernier. All of the data  collected collected using this app is turned into graphs and charts which are easy to interpret.

Applications for Education
This app is a mobile science lab which students can take anywhere in order to conduct experiments. Students can collect data, take photos, and record observations while in the field. This is an exciting and practical way to incorporate cell phones into the learning process.
