Bottle rockets have been a source of entertainment and education for many years . In many science classes, the constructing and launching of bottle rockets are used as a tool to provide students with a real-world application of forces. However, what is a bottle rocket and what does it have to do with science? Why do bottle rockets fly? A bottle rocket is a type of model rocket using water as its reaction mass. They are usually made with an empty two-liter plastic soda bottle. The water is used to pressurize air in the bottle for launching. Which is released rapidly through an opening as it tries to escape. A rocket is subjected to the forces of thrust, lift, drag, and gravity just like airplanes. Thrust is the force that causes
During the late 1950’s the space race began. This was a race to see who could achieve the most space firsts, between the USA and Russia. Sonny, O’Dell, Sherman, Roy Lee and Quentin live in Coalwood, West Virginia.The space race inspired these boys, who decide to call themselves the Rocket Boys, to make their own rockets. The BCMA (Big Creek Missile Agency) was born when Sonny called a meeting with his friends in his room and discussed how he wanted to build rockets. With the help from the a man at the town’s machine shop, Mr.Bykovski, the BCMA built its first rocket, called Auk I. The rocket was named after an extinct bird that was unable to fly. Auk I was equipped with a wooden bullet shaped nose cone, an aluminum tubing body, fins, and a soldered washer at the bottom. The boys mixed together black powder and postage stamp glue to act as fuel for their rocket. The rocket flew up 6ft, and then fell back down. The rocket boys later found out that the reason their rocket stopped flying was because the solder melted. The BCMA was happy with the result from the rocket, because it was their first ever rocket to fly.
Cost management plays a major role when maintaining profit margins. Management must be able to find in which areas of a business costs must be reduced and the consequences that such reductions have in the overall company. In some situations management must change the way the work is being done in order to decrease costs while in other cases changing one supplier for another might be enough, in both situations a tradeoff will occur and the consequences will impact the company as a whole.
The Reason that people need a tank when they play paintball is because you need a way to force the paintballs out of the gun and this cannot be achieved effectively by just using a spring. What they decided to do was to fuel the paintballs by pushing them with a gas. The way in which they did this was to put the gases, either Oxygen, Carbon Dioxide or Nitrogen under extreme pressure until they turned into a liquid and once they are in a liquid form they can be blown into a tank which probably looks something like this.
At the beginning of this assignment, both McKenna and I had no idea how to build a bottle rocket. After visiting several websites and researching multiple ways of making it, we settled on a single bottle rocket with a rounded nose cone and three fins. This was chosen because it was the easiest model to create and that meant a less likely chance of messing up. We were just concerned with getting the rocket into the air. The rounded nose cone was created by layering paper and then rolling it and folding it in way that fit around the bottle and was not a completely pointed cone. We then layered it with duct tape to keep it somewhat stable. Before attaching it to the bottle, we put five fishing weights in the top and then stuffed the remaining space with paper. After that, an outrageous amount of duct tape was used to put the nose cone in place. Following that we started to work on the fins. There were two different fin shapes that we tried. The first was a long skinny triangle. The second type was a rather wide triangle with two of the corners chopped off a bit. Each of them was cut out of cardboard and was then covered in duct tape in order to keep the cardboard from getting wet and
In this inquiry the relationship between force and mass was studied. This inquiry presents a question: when mass is increased is the force required to move it at a constant velocity increased, and how large will the increase be? It is obvious that more massive objects takes more force to move but the increase will be either linear or exponential. To hypothesize this point drawing from empirical data is necessary. When pulling an object on the ground it is discovered that to drag a four-kilogram object is not four times harder than dragging a two-kilogram object. I hypothesize that increasing the mass will increase the force needed to move the mass at a constant rate, these increases will have a liner relationship.
The biggest difference between model rockets and rockets are their engines. Model rockets are powered by solid engines and rockets are powered by liquid engines. Since model rockets use solid engines the heating is not essential for launching, unlike rockets. Rockets use liquid engines and if the liquid fuel is not heated up properly then the rocket might collapse. In this step one must be careful on how they do the chemical reaction because one faulty step could ruin your rocket and your opportunity to launch.

Before starting this class I had very little information about Cambodia, but after we started reading In a Rocket Made of Ice and going over the history and culture of Cambodia I learn a lot. Three Major things I learned about Cambodia are that Cambodia is a full of hardship ranging from human trafficking to a bloody genocide, but I also learned that Cambodia is a place full of people who are very kind and religious. Cambodia has very bad human trafficking problem, which causes a lot of the people in Cambodia to be sold into slavery. Cambodia is trying to combat the issue, but with lack of infrastructure its very are to fight. United States has recently seen an increase in human trafficking has well, but the United States has a very strong
Robert Hutchings Goddard is an American rocketry pioneer; he is considered the father of modern rocket propulsion. In 1926, Goddard had constructed and successfully tested the first rocket that uses liquid fuel. The flight of Goddard’s rocket on March 16, 1926, at Auburn, Massachusetts, was as significant step to improving rockets. The first culture that started to experiment with rockets was the Chinese, the date reporting the first use of rockets was in 1232. The earliest rockets were used by the Chinese to defend their home from the Mongols by shooting a barrage of "arrows of flying fire.". They started to fill gunpowder into bamboo tubes, then they put the gunpowder filled tubes on arrows and began to launch them they eventually found that the gas can launch the arrows. When the

The rocket launch project served to demonstrate how momentum, stability, drag, and a recovery system can aid a soda bottle rocket in flying. Though our rocket was not the prettiest, it did the job of utilizing water and compressed air to shoot into the air. Our challenge was to create a rocket that could withstand the force exerted on it during the launch, while making sure it could protect the egg inside of it. We tried changing many things until we created a rocket, cone, fin, and recovery system combination that worked. The overall look of our rocket included a plastic cone on top of a two liter bottle, and 4 fins around the base. Though our rocket
When I was eight, I wanted to be an astronaut so I could explore the moon and go to the stars. Now that I am eighteen, I have decided I want to build the spacecraft that will take others to the moon and the stars. In my college experience, I want to gain the knowledge and insights that will enable me to fulfill my dream of designing and testing spacecraft.
ITRODUCTION As it becomes evident from historical observations, research is the creation of the curiosity which is caused by the human nature. A lot of the discoveries that occurred in the ancient years were achieved by luck. After that they acquired experience and skills to explore more and more for new achievements. The acute interest in discovering new methods and ideas gave answers to questions which faced the society of each period.
