If you think about it, you need to remove the big stuff before you can remove the smaller stuff.
By putting pebbles on top, it will filter out things like other rocks, twigs and the like. Gravel will filter out anything smaller that gets past the pebbles, and sand will do the same. It's all a matter of scale. The cotton balls will filter out the smallest possible detritus.

For school we have to make a water filter with only three layers do you think fine gravel coarse gravel and cotton balls are good layers and in which order and will brown dirty watercome out clear?
I suggest you put the coarse gravel on top, the fine gravel in the middle and the cotton balls on the bottom. The less gaps in the material the more dirt will get trapped. The coarse gravel will take a small amount of the dirt out. Then the fine gravel will take out more and finally the cotton balls will most likely take out the rest leaving an evenly distributed amount of dirt in each layer. If the cotton balls are on top then the dirt would fill the cotton balls and some of it might still come through then the layers of gravel may not be effective to such small pieces of dirt.
