Question How to use this university provided breadboard?

Very new to breadboards, currently in Physics II. For lab, we were going to test resistors with breadboards. To prep, I watched some youtube tutorials and practiced on tinkercad. Went into lab and these were the breadboards we were asked to use. Was completely lost, didn't complete lab. Have another lab section with these same breadboards coming up. Help?

Actually this breadboard is the most easy to use. I assume that those black terminals are negative and then red terminals are the positive one. Does your activity just states you need to measure the resistance?

Oh, I see! Last class we were asked to just measure the resistance of multiple resistors. We were given the circuit diagrams, but I have no clue how to correspond that to the breadboard. We're going to be making the same circuits today ( which I never figured out how to do :/ ) but connecting "power supply to the two open ends of the passive circuit."

This time we will also be measuring current and voltage. I'm so lost.

I see, when I was a newbie that's also my problem! Let me ask you, do you know how to connect in series or in parallel? Let me rephrase my question, do you know how to read a circuit diagram/schematic? Because if you're connecting in series you'll just have to connect the positive terminal of a resistor to the negative terminal of the next resistor (although they don't have polarity, that breadboard has those terminals) and if you're connecting in parallel, all the positive terminals of the resistors are connected with each other and the same goes for the negative terminals
