Getting Started with Science Journal
Tip

It can be helpful to change the sleep settings on the phone, so the screen doesn’t turn off during your experiments. To change, go into your phone settings and click on the Display icon. Once in the Display menu, select Sleep and change to 10 minutes or more.

Experiments

Use Science Journal to document your investigations.

The Science Journal app is a digital science journal that you can use to document projects through notes, photos, and your phone's built-in sensors.

As you begin asking questions and coming up with your own investigations, Science Journal gives you the capability to record your ideas and observations. Begin by creating a new experiment.

You can rename your experiment by tapping the pencil icon at the top of the screen. Once you’ve set up your experiment, you’re ready to make observations!

Toolbar

As you begin asking questions and coming up with your own investigations, Science Journal gives you the capability to record your ideas and observations through text notes, photos, sensor recordings, and more. You do this by using the observation tools in the toolbar at the bottom of the screen.

Try writing a text note and adding it to your experiment feed by tapping the Meter mode button. This way you can add a hypothesis and observations to your experiment.

Using Sensors

Science Journal enables you to explore your world by using internal and external sensors. To start measuring light, sound, movement, and more, tap the Meter mode button.

Once you’ve selected a sensor, you will see the measurements that the phone is making in real-time. To make note of a single sensor measurement, tap the Meter mode button.

To capture a sensor measurement over time, you create a new trial. A trial will contain the data you’re measuring and notes and observations you make during your experiment.

Choose the sensor you want to record. Once you’ve selected the sensor, press the Record button to start capturing data.

Add snapshots, notes and photos to keep track of your observations while recording.

Press the Record button again to stop recording. Your trial will appear in your experiment feed. Tap on the trial to see what you've recorded, as well as any notes you've taken.

After you review your recording, you can explore some of the additional sensor features that Science Journal has to offer. Go back to the sensor tab in the toolbar and tap on the three-dot menu in the top right corner of the sensor card.

Tap 'Enable audio' to hear your graph as it changes in real time. You can change the sound created by tapping the 'Audio settings' option, and you can stop the audio by tapping 'Disable audio'. You can also create triggers to automate your sensor recordings. Give it a try!

Finally, you can manage your sensors in the Sensor settings screen. Go back to the sensor tab in the toolbar and tap the Meter mode button on the sensor card.

You can enable and disable different sensors. You can also use this screen to connect to external sensors via bluetooth. Learn more about connecting to external sensors in the following activity: Connecting to External Sensors

Now that you know the basics of using Science Journal, you can use it to conduct experiments and explore your world.
