Hope Frihauf and I created a water powered rocket that we constructed from a website from NASA that we found.
For our independent variable, we chose to change the amount of water that we put in our rocket, we chose this variable because it was a common variable to change, and we thought that it would be the variable that would show the most change for our graph. Question: If there are different amounts of water in the rocket, which amount of water will make the rocket go the highest? Hypothesis: If the amount of water affects the distance of the rocket, then the rocket will go the farthest with a medium amount of water because there will be an even amount of air pressure and water.
You can vary the fuel (water and air pressure) and potentially how it exits the bottle in order to change the force of thrust.
You can change the pressure, volume of the container, volume of fuel, density of the liquid, and nozzle shape in order to change the force of thrust and make your bottle rocket go higher. We will have to find the perfect medium between too light and too heavy of a bottle with fins.
Rockets have well-designed shapes and fins in order to keep them flying straight. What works the best?
It works best if you have the right number of fins with the right shape, size, and location. Also, we will have to have a bottle that is longer in length, so that it has a greater moment of inertia. The greater moment of inertia will make the bottle go higher because it will not wobble..
How do you minimize air resistance in order to allow your rocket to fly as high as possible?
In order to allow our rocket to fly as high as possible, we must figure out how to have a laminar flow with our rockets. If it can go as straight as possible, then the rocket will go higher. In order to do this, we must try to minimize turbulence by changing the shape (drag coefficient) and making sure that the added things, such as fins and the parachute, are secure.
