### Five Observations Students Can Record With Google’s Science Journal App

The new school year will be here soon and I haven’t taken a break all summer. I’m taking a short break from the Internet to go fishing at one of my favorite places in the world, Kennebago Lake. I’ll be back with new posts on Saturday. While I’m gone I’ll be republishing some of the most popular posts of the year so far.

Google’s Science Journal app provides some neat tools for recording data and writing observations. Within the app students create notebooks for recording experiment data and observations. Students can also use those notebooks to simply organize observations by topic. There are sensors built into the app for recording sound, speed, light, direction, and magnetism. Here are five things that students can record with Google’s Science Journal app (click here for Android version and here for iOS version).

1. Decibel Levels
Ask your students if a basketball clanging off of a rim is louder in an empty gym or a full gym? Have them make a hyphothesis then test it in your school’s gym. (Check with your physical education teacher to make sure it’s okay to borrow his or her classroom).

2. Speed.
Have students record how quickly or slowly they walk down the hallway.

3. Speed and Sound Correlation
Have students record the speed with which they walk down the hallway. Have them record the sound at the same time. Ask them to try to identify a correlation between the speed with which they walk and the amount of noise that they make.

4. Light
Today, whenever I look out of my office window I am nearly blinded by the reflection of the sun off of the frozen snow. It was brighter earlier today when the sun was hitting the snow at a more direct angle. Students can use the Science Journal app to measure and compare the brightness of one place throughout the day.

5. Light and angles correlation
The Science Journal app has an inclinometer function. Have students use that function to measure the angle of the sun to a fixed position throughout the day. Have them use the light meter whenever they use the inclinometer. Then ask them to determine the correlation between the angle of the sun and the brightness at the chosen spot. They might be surprised at the results.

Bonus item:
I plan to use the Science Journal app on my phone to record the cries of my baby in relation to the speed at which I walk and bounce her. Maybe I will find the perfect speed at which she always stops crying.
