A). A rockets works because of newtons 3rd law: every action makes an equal and opposite reaction. When whatever is inside the rocket (aka, it's fuel) is let out, the force of it's escape downwards is also the force of the rockets push upwards. This force, as long as it is greater than the weight of the rocket, will push the rocket up into space!
B). Design effects the way a rocket will fly in many ways, the more the fuel, the faster and longer a rocket will fly; The greater the weight, the more it will be affected by gravity; The lower the fins, the more stable the rocket will be; and the nose cone can help change the rockets center of gravity.
C). As stated above, newton's 3rd law causes the rocket to rise of the ground. Newton's 2nd law helps us to figure out how much force we need to push our ship, and newton's 1st law tells us that, because there is no friction in space, once we get there we're home free, sort of. I suppose we would still have to deal with the decent into the martian atmosphere...
At this point I would show a picture of my rocket, however unfortunately It has gone missing, perhaps the zombies took it. Anyways, there are a few revisions I was meaning to make on it. First, remove the weight on top and add 2 more fins, our first draft tried to predict the way the rocket would tilt, but the weight on to proved to ave to much of a negative effect on performance. Next, we will lower the fins to make the rocket more stable, NASA says so.

Above is a picture of our final draft.
Materials used: Duct tape, 2L soda bottle, cardboard, paper, hot glue.
One thing that surprised me is how much of a difference a skirt and a dome can do, our rocket went from 12m to about 20m with such minor changes! Another thing I noticed was how the rocket did't lose any stability by using only 3 wings, or at least no very much... The biggest difference (that I first noticed) in our final design was that we used much less water, by doing this, we made to rocket go much higher, this is because we could add more psi, however, the water we did use helped get the rocket of the ground, so it did have some uses. The unit rate for the average velocity of our 2nd draft of the rocket was exactly 11m per second. Overall I think our rocket was very successful. We didn't actually measure the last time, but I think our rocket went about 20m high and I consider that a huge success! However, If I were to make another version of this rocket, I would probably make the dome and skirt better, finding an actual dome for the dome, and maybe making the skirt more stable.
