## Arduino Science Journal Description
The Arduino Science Journal (formerly Science Journal, an initiative by Google) is free and allows you to gather data about the world around you by harnessing the sensors in your smartphone as well as sensors connected to Arduino. The Science Journal transforms smartphones and tablets into science notebooks that encourage students to explore their world.

The Arduino Science Journal app is recommended for students from 10 to 18 years of age.

About Arduino Science Journal
With the Arduino Science Journal, you can learn interactively, conduct experiments and iterate on findings.

•  Enhance your existing lesson plans: use the Science Journal with activities and assignments you have already prepared
•  Classroom & home-school friendly: you don’t have to be in a classroom setting to start exploring. The Arduino Science Journal can be used to run experiments straight away, as long as you have your smartphone or tablet with you! 
•  Move learning outside: the use of mobile devices along with the types of experiments we offer encourage students to get out of their seats and open their eyes to the world around them through the power of science
•  Science and data have no secrets: you can easily record your observations, store your data sensors in real-time and analyse them, just as a proper scientist! 
•  Connect the digital and the physical world from your pocket: go through a series of simple tutorials and start having fun with science

With built-in device sensors as well as external hardware, you can measure light, sound, movement, and much more.  You can also compare results, and even set triggers. 

Together with the external hardware, (not included with the app), students are enabled to conduct more complex experiments, and advance in their scientific studies. As long as the external sensors are compatible with a Bluetooth-connecting device such as a microcontroller, there is no end to what experiments the students can make. Some popular sensors that the app can work with are: light, conductivity, temperature, force, gas, heart rate, respiration, radiation, pressure, magnetism, and many more.

The app is classroom-friendly, since students can sign in on any device and access their experiments to continue exploring the world, wherever they are!

Permissions notice:

• Bluetooth: needed to scan for Bluetooth sensor devices.
• Camera: needed to take pictures to document experiments and for the brightness sensor.
• Photo Library: needed to store pictures taken to document experiments and for adding existing photos from your library to experiments.
• Microphone: needed for sound intensity sensor.
• Push notifications: needed to inform you of recording status when backgrounding the app.

Benefits of using the Arduino Science Journal
• It’s free and simple to use
• Easy setup: download the app and start exploring with your phone’s built-in sensors
• Cross-platform support
• Portable: enhance your home learning or bring your device outside to study the world around you
• Fully compatible with Arduino hardware: keep experimenting with the Arduino Science Kit Physics Lab, as well as the Arduino Nano 33 BLE Sense board
• Google Drive integration, as well as local download

## Arduino Science Journal Reviews in United States

### ***** "Simple and Inspiring"
A good introduction into conducting your own experiments.
-- c1pito, 2022-10-10

### ***** "Incredible"
I wish I had known about this years ago. As an engineer I’ve been looking for ways to use my phone as a measurement instrument and this is it!

Get it and contribute to Arduino!
-- gilesStyles, 2022-05-04

### *---- "Radionics"
One of the worst science apps out there so bad
-- chasdog1234545, 2022-02-07

### *---- "Not working"
This app once worked. I could submit a technical question on a website link I found. Not sure what else to do? Tried to remove and reinstall nothing works anymore. Will freeze on loading dashboards with a blank screen.
-- Iiserafinaii, 2022-01-17

### ***** "Joe"
🦆🐮🐥🙉🐮🙉🐣
-- jfjskdjhdnkdcknnd, 2021-12-14

### *---- "Awful"
The worst physics app ever, great effort(not really) in making this app but awful execution, very complex, also it didn’t work when I needed it to. I walked down 4 flights of stairs by myself and tried to gain a signal in the middle of a parking lot looking like a fool just to get no signal. I really hope you guys reimburse me for my wasted time, my group almost publicly lynched me after I came back inside the lab with no data. Thanks again for a lot of wasted time and a not so fun experience with this dumb app! BOOOOOOOOO🤡
-- Alejxwosj, 2021-11-02

### *---- "Blank screen?"
I have an iPhone 13, iOS 15.02 and all I see is a white screen that begins with you have no experiments.  Fair enough, select the plus symbol on the lower right and now I get, “You have no observations yet”.  Very true, but the app doesn’t allow me to make any observations.  

There isn’t any sort of command, tool bar, option.  Rotating the screen, pinch, tap, pull down or any command doesn’t reveal any sort of resolution.

Oh, it must be a setting issue.  Look for the app in the setting menu and only the 2 options I see Siri access and language.

I’m stumped.
-- Kii20, 2021-10-24

### *---- "Quit working on iOS 15 update"
Please fix
-- Mikes Yoga 720, 2021-09-21

### ***** "The App Without Problems"
This app doesn’t have any problems or things I don’t like. So I decided to give it 5 stars.
-- BugOrFish, 2021-02-18

### ***** "Engaging Science within the application"
I am grateful to experience this app. I would consider the app an essential. it’s data potential is personalized making anyone curious enough a scientist.
