I got this from my physics prof.  Take a full glass of water, preferably a wine glass, and and some food colouring for the water.  Take a clear piece of acetate and cut it in a circle for the top of the glass.  The piece of acetate needs to be larger in circumference than the glass though.  Place the acetate on top of the glass and turn the glass over.    Explain why the water doesn't escape.  The answer might surprise you.  A hint is because of pressure but how much is there, where does it come from, and what is its dimension?

That depends on your personal strengths. Physics has always been easier for me.

Well see as though you dont really have much time for a project that involves a control... But here is an awesome listing that has loads of ideas with explicit instructions not to mention material list for a wider variety of projects. Since I have no clue what realm of science you were intrested in... This has a little bit of them all! Good Luck!\n\nhttp://school.discovery.com/sciencefaircentral/scifairstudio/ideas.html

http://educate-yourself.org/fe/fejoewatercell.shtml\nI'm unsure of anything that describes how to really make one.\nThis site tries, but it's rather goofy to follow. Maybe you'll have better luck that I would.

Set up a mathematical model for the experiment in question and use the scalars and constants provided to create the formula needed to solve.

Have a look at these links, I know they have instructions for making all kinds of models.\n\nScience Fair Projects\n\nSelecting the Subject\n\n•Hundreds of free science fair projects are categorized under the following topics. \n\nhttp://www.freesciencefairproject.com/\n\nhttp://www.scienceproject.com/\n\nhttp://www.ipl.org/div/projectguide/\n\nhttp://www.all-science-fair-projects.com/\n\nhttp://www.energyquest.ca.gov/projects/index.html\n\nhttp://collaboratory.nunet.net/timber/scifair/2proj.htm\n\nhttp://www.ipl.org/div/kidspace/projectguide/\n\nhttp://www.niles-hs.k12.il.us/jacnau/IJAS/\n\nhttp://www.plymouthschools.com/Science/scifair/scicover.htm\n\nGood luck.\n\nKevin, Liverpool, England.

I was a rock star in college physics!   Top of the class!  But I can't remember any of it now.  My teacher always said to start each solution by drawing a picture, then making a list of the varriable you know, and writing down the equations you thik you might need to solve.  It worked for me!\n\nPost your problem, maybe I can help.  Traditional physics problems have not changed much in the last 5 years, maybe I can remember.

u can consult ur physics book

Its fairly simple to make using a readily available liquid. I'll leave you to search the Internet then decide if you want to make it by yourself or get help from friends

to make an ideal one you would look at the fluid dynamics equations.\n\nHowever ideal ones are very thin at the end and would break so to make real ones you would need some engineering know-how. So that it is strong enough and generates enough lift for your purpose.

1)Start by modelling the speed of a ball in one direction; take into account friction force (negative drag) that is equivalent to negative acceleration. Loop until speed is equal or less than to zero. Then, stop.\n\n2) Do Exactly the same, now in a 2-D space: model how'd the would move given an initial vector speed.\n\n3) Model a "Hit" on a ball: given an instant (vector) speed plus a "Hit Vector", compute the resultant vector; then use that vector as the initial speed again.\n\n4) develop a "Hit?" function that returns true if the difference between the centers of the balls is less than the diameter, or if the center of the ball is closer than a radius to a wall (the stick can be thought of as another ball)\n5) Every time Hit? is true, recompute vector speed for every involved ball.\nVoila! you have your game. Let me know if it's useful and the results.

Take a physics class.  It's mostly common sense.
