Formula:
M1V1 = M2V2
M= molarity
V= volume
The M1V1 is also known as stock which should have the higher concentration since it is your beginning solution.
Serial Dilutions are successive dilutions in a row.
At first I didn't understand what dilution was really. However, after the lab and physically diluting a solution helped me understand better. It's basically taking the solvent in equal amounts and adding a little bit of the concentration from the previous cup/solution into a cup. It just decreases the amount of concentration of the solute. It's kind of like having a city with tons of people inside it and the people are atoms of the solute. But then it gets too crowded and people start moving to suburban areas (less crowded). Then finally some people move from suburban to rural ares where there isn't many people (atoms). That's kind how I think of it.

That's a really good analogy with the city and suburbs! And I completely agree: I didn't quite get a grasp on dilution until we actually did it in class. Your pictures are really cool! Especially the deep purple color makes the dilution clearly apparent.
