Hi i have a scince fair in March and i have an idea for it. What if i got frog legs and tried to harness eletricity to them and make them move?!?! how would i do that? getting the legs is no problem, but which kind should i use? ( i am not killing a live frog) and if this wont work please igve me winnning science project ideas thanks.

How about something that does NOT involve hurting animals? After all... this is a science fair, not science. You will not get any new information from any experiment on living beings that you can do at your age.
Just a thought. And you are old enough to understand the value of life yourself.
OK... this one is COOL:
http://learn.genetics.utah.edu/units/activities/extraction/
Extract DNA like McGyver would! With "random" stuff you find in the kitchen.
And with a little help you could do the real thing with the real chemicals scientists use and then compare your results and talk about the ease/difficulty with which the experiment succeeded (failed?). You can modify the protocol and see what happens, etc..
To be honest with you, I am a professional physicist and I know a little bit about DNA and stuff, but if a 7th grader would show me that she can successfully extract pretty good looking DNA with nothing but household chemicals, I would give her a price any day.
Good luck!

If you don't want to kill any frogs, you can shock some live ones. But getting shocked animals to move isn't much of a trick, so I'm guessing that you actually want to do your Frankenfrog thing with legs from dead frogs.
Unfortunately, the frog has to be fairly recently dead for this to work, so I'm afraid that to do what you want you will either need to kill some frogs if you really want to do this project.
You ask for other "winning" ideas. What about the frog leg idea attracted you? Why would you consider it a winning project? Is there another way to demonstrate that aspect of the idea? Are there other resources that you can use to demonstrate the Frankenfrog thing and have your project concentrate on the neurological/biological aspects?
You don't have to abandon the idea if you don't want to kill frogs. Making frog legs twitch is pretty much just a parlor trick anyway (surely there's a video of it somewhere online that you could use). Demonstrating your understanding of the processes involved would go a long way toward a winning project.

I'm not sure if that will work, but I have another project in mind. I have done this project myself, and it comes with pretty good results. The project is you have to find the energy levels in different types of nuts. The information you can base your hypothesis on iare the nutrition facts, and the amont of calories, fats, etc. in the nut. To actually find the energy levels, you need to build an apparatus.
This apparatus should be a can, like a large coffee powder can. First, the bottom "lid" must be off!!! It should have holes on the bottom in a ring, and two holes that are on opposite sides. What you must do is you must put a metal stick through these two holes. Hanging on the stick should be a smaller can of water. Place a needle in the cork, and put a nut on the needle. Then, burn the nut. After the nut is completely burned, check the temp of the water. Whichever has the highest temperature, that is the nut that produced the most energy.

It does work. If you suspend a frog leg on a stand and clip an electrode to the top of the leg and one to the foot end, and then connect each electrode to a battery (with a switch in one of the electrode lines, when you make the connection, the leg muscle will contract. That was an experiment I had to do in Anatomy and Physiology lab in college.

I remember doning this in that grade but now the Ideas wont be useful today but I would suggest to find out what project someone that you don't get along with and try to do it better than that person than they will have to think of one instead of you.
