I am working on my thesis and I must record the acceleration on each floors of our 5-storey structural model. Thus, I will be needing 5 accelerometers but each accelerometer needs both SCL and SDA connections to the Arduino.
What Arduino should I use? Will i be needing multiple Arduinos too? Or is there any other way?
We are planning to use the MPU6050 accelerometers.
I am new to this so your help will be very much appreciated. THANKS!
You are posting your question in the tutorial forum.
You can have multiple devices on I2C.
You could use multiple Arduinos for this if the distances are large.
Many new users start with an UNO or a Pro Mini.

We are planning to use the MPU6050 accelerometers. They say I should be using an I2C to connect the 5 accelerometers to one arduino. Can you suggest any specific model of both I2c and Arduino? Should I be using breakout boards too?

Hi,
Welcome to the forum.
Please read the first post in any forum entitled how to use this forum.

If all you are doing is data logging, then the basic UNO will probably do the job?
Are you storing the data on the controller or are you measure passing it to a PC or recordingdevice?
There are shields that will hold SD cards.
If your 6050 are floors apart, I2C comms will not work over that distance.
You may need a controller on each floor and a comms system between them with a master to collect and store data iff needed.
What is your project exactly, I'm not sure if 6050 will measure differences in the earth's gravity when compared at different heights of the magnitude you are using.
Can you please tell us your electronics, programming, Arduino, hardware experience?
Tom.. 
AFAIR the I2C address range of a MPU6050 does not allow to have 5 accelerometers accessible at the same time. Then you'll need an I2C multiplexer, which also can do the 5V/3V level shifting.
