Science Journal is a free digital science notebook from Google which turns Android and iOS devices into a data logging and recording tool.

Each experiment is a blank page that students can fill with notes and photos as they observe the world around you. At the heart of the app is using the built-in sensors within your device to measure real-world data. Students can add in measurements taken by the app, along with their thoughts and observations, as well any photos they’ve taken.

Sensors can record information over time, as well as make a snapshot readings as they go along. As long as your tablet/phone has the appropriate hardware, students can use the app to measure light, sound and movement as well as an accelerometer, a magnetometer and a compass.

Google have released more than 20 activities that you can do with the app. For example try attaching your phone to a spring and let it bounce up and down.

The app can also connect to external sensors via Bluetooth to allow an even wider range of measurements to be made. The recorded data can be exported as a CSV file.
