Okay, you have very little time, right?
So first of all, you should understand the function of each simple machine and how it manipulates work. Machines don't make work disappear. Actually, they just change the way work is done. First of all, I would suggest you to do some research about the different machines, like pulleys, levers, ramps, and I bet there are lots more. Look around the house, grab some tools, choose a random simple thing to do, and start building. It's like rolling a stone down the hill; once it's started, everything'll be easier. Good luck!
