Need some help for a science project.

how do you get the wires out of the servo motor

Not sure what you mean...

There is usually a three wire connection coming out of a servo into a small plug with holes for 3 connectors- usually red and black for 5v and ground, and yellow or orange for the control. You need to stick wires (preferably with pins on the end) into those sockets and take them to the power supply and Arduino pin. You can see the 3 way plug clearly in this pic of your servo.

You may find that standard size servo a bit big especially if you have 5 of them next to each other. Might be an idea to consider a micro servo like this.

Edit.... you should have a look at DuaneB's acclaimed servo tutorials here and here.
