how can i start a practical assignment on osmosis?

Are you asking how to write it up? You say you've already done the experiment.\n\nGenerally school practical write ups have an introduction, methods, results, discussion and conclusion. Start with your methods and results then do your discussion, write your introduction and conclusion last once you know what the data shows.\n\nIf you are asking how to do the practical first you need to work out what you are testing e.g the effect of solute concentration on osmosis. Work out what controls you need and what you will need to keep constant. Next you need to work out a way to measure the osmosis, probably in this case measuring the swelling (or shrinking) of the potato chip either by volume or by mass.

The layman's term I always heard was "learning by osmosis."

Ask your instructor to narrow the assignment.\n\nOr, make an assumption as to what the instructor wants, and go forward using your assumption.  (I did this once, and because I was the first one done, the instructor accepted my assumption, although it wasn't what he had inmind.)

You don't give a location (country/city/town) so I don't know, but couldn't you ask your college professor for some ideas ... or some fellow students in the know.\n\nIf you are doing a home study course, another idea might be to make enquiries at your local water utility provider.  Make sure you speak to someone who has all the requisite qualificiations to help you.  Good luck!

I assume you know what osmosis is.\nIt would be nice to end up with enough results to plot a graph (LINE graph) so you will need at least four (more is better) solutions of different concentrations. Sucrose solution is usually used.\nUse a BIG potato so that all your samples are as similar as possible.\nThe easiest way to get uniform samples is to cut cylinders with a cork borer, then cut into 5mm disks.\nPut 10 discs into each solution.\nWeigh 10 discs before they are put in, then CAREFULLY blot them dry and reweigh them next day.\nCalculate the change in mass per gram of potato (you could expect some to gain, some to stay the same and some to lose so you will get some negative values).\nPlot a line graph of 'change in mass per gram of potato' AGAINST 'concentration of solution'.\nNow you must consider what the graph show you.

To do it accurately you may need a PhD. \nOtherwise, build a trough with an uneven bottom.  Then build a ramp to the trough.  On the top of the ramp have a bucket that is constantly being filled with water from a fish tank pump.  Make the bucket so that when it is filled to a certain level it tips and pours down the ramp into the trough.

The easiest way to understand osmosis is to think about a bottle of strong perfume.  When you take the lid off the molecules spread out filling the room slowly with smell.  Molecules move from an area of high concentration to an area of low concentration.  (that is your answer, I believe)  Another way to understand it is to drop food coloring into a large bowl of water.  It will slowly spread throughout the bowl.
