Balloon Car Essay Example for Free

Balloon Car Essay Our first idea was to make a paper Lamborghini. We looked on many websites to find ways to make an origami-type Lamborghini. All of the instructional videos that we found were at least an hour-and-a-half, or did not even look like a car. As we got to school I had the idea to look up paper models of Lamborghinis, the kind where it has the dotted lines and you cut it out, fold it where it says to, and tape it together. We printed it out and we could not get it big enough on a standard-sized piece of printer paper. There were five basic shapes on the model so we just decided to take five pieces of paper and draw the shapes much bigger and duplicate the design. After we drew the design and cut it all out we decided to cut out pieces of cardboard the same shape and put it behind the paper so it was more stable and added some weight. For our balloon, we put a hole in the back of the car that we could put a straw through, and taped the balloon to the straw. We taped the straw up on the back part of the car so when we blew up the balloon it would go straight up. Our wheel idea came to mind when I was drawing out an idea for our car. I was using a blue highlighter, accidentally dropped it, and we discovered how fast it rolled. We decided to try to pop out the center part of the highlighter so we could put a piece of wire through the center through the two ends and hook the wire through the bottom part of the sides of the car. We were going to use two highlighters, one in the front and one in the back, instead of â€Å"4 wheels†. However, we could not get the center out of the highlighters. We went â€Å"dumpster diving† around the school and ending up getting pop caps from Ms. Chambers. Since our idea was to use highlighters and the wire, once we hammered a hold through each of the caps, we couldn’t figure out how to make them turn because we did not have a good axle. We tried to use just a straw for the axle and that did not work. We then tried to compact the straw so it was not as big around and that did not work either. We also tried to put nails through the caps and stick the nails into the side of the car but that did not work either. Our next idea was to go to the band room and put four timpani wheels on the bottom of our car, but they were way too heavy. Eventually we smashed the straws to make them thinner and put it inside a hollowed-out pen. This made a good axle and we used this for our car. As we tested our car to see if it would move, it did not. We realized that our car may be too heavy so we had to think of a Plan B. We decided to take five kabob sticks and hot glue them side-by-side so it was pretty much flat. We then put our Pepsi cap wheels on the bottom, and taped the straw and balloon on top. We tested it and it moved over five meters and the path it took was fairly straight. The speed of our car is 2. 37 Meters/second. We found our speed because it took 2. 37 seconds to travel one meter. Our car is a good example of inertia. It keeps moving until its â€Å"power source† (balloon) runs out of air. It stops it because if the balloon never ran out of air, and if there was nothing in its path, our car would never stop moving. It’s also an example of acceleration because it starts off slow, gets a little faster, and as the balloon starts to run out of air, it slows down again. It’s also an example of every action has an equal and opposite reaction, because as the balloon releases air the car moves.

Propaganda, Patriotism, and the War on Terrorism :: Argumentative Persuasive Topics

Propaganda, Patriotism, and the War on Terrorism On college campuses across the nation, efforts are being made to silence professors who encourage students to probe the history of U.S. foreign policy in the effort to understand the September 11th attacks. Recent articles in The Chronicle of Higher Education report that students have complained to deans about professors critical of U.S. foreign policy, and boards of trustees, deans, and college presidents have drafted resolutions and issued public statements condemning their views. Professors have been shouted down, received volumes of hate mail and, on some campuses, death threats. In one case, a trustee publicly invited a professor "to take a hike." Historically, such attacks on free speech have risen sharply in times of national crisis -- precisely when a full range of views is sorely needed. They are particularly disturbing on campuses of higher education that should be strongholds of people who defend independent thinking. The nature of the arguments offered against these dissenting voices are very troubling; so too their political effects. The arguments fall into two groups. First, professors are charged with showing no concern for the feeling of others: they lack taste and judgment; they are insensitive, self-indulgent and offend others at a time when emotions are raw. In being so inattentive to their students' emotional sensitivities, dissenting faculty violate the trust students place in them. Now is not the time for critique, but for emotional nurturing, reassurance and national solidarity. Second, professors are charged with offering excuses for the attacks. Their examination of the role the United States may have played in creating conditions that make terrorist acts more likely amounts to a justification of the acts themselves. There is an emotional tyranny at play here, and its effect is to obstruct processes of understanding that alone will aid us in our ongoing debate over how to come to terms with terrorism. What do I mean by tyranny? In the first instance, we are being told that feelings alone are appropriate now. It is too early, indeed, it is tasteless, to begin to sort through our role in the complex factors that brought these people to their heinous acts. But understanding is crucial to wise action, and action, as we see in each morning's news, is most certainly being undertaken in our name. While we are being asked just to feel, the administration and its congressional allies hurry to pass laws that threaten our civil liberties at home, and engage in a massive war effort likely to foster greater resentment abroad.

A University Education Is Not Essential for Success’ Essay

In a general point of view, university education is necessary for success and that is why parents nowadays would ask their children to finish their Bachelor degree as a minimum request. They think that university education is an essential element for success. However, I do not think that that is true at all. University education is only one of the keys for success but not the only key to achieve success. Some people may think that what success is being a millionaire or even a billionaire. Nevertheless, in the reality, being that kind of capitalists does not require any degree of education. It is a truth that having a higher degree of education can let us apply a higher salary job but it is not essential for being the tycoons. There are some real life examples to prove my argument is truth. Bill Gates, Steve Jobs and Richard Li choose to give up their opportunity to finish the university education and start their businesses. Although they do not have any diploma of graduation in the university, they can still run their business very well and earn a huge sum of money. University education is not an essential element for being a millionaire. Earning enormous figure of income does not request any degree. Moreover, what success is not only making a huge sum of money but also making our own dreams come true. Not everyone is giving weight money to a high position and what he or she wants is to accomplish his or her dreams. Different people have different dreams and some of the dreams may require a high level of education such as being a doctor or a lawyer in Hong Kong. It is necessary for the one who has these dreams to have a good academic result in A-Level exam and finish the university study to get the certification. However, some dreams do not claim any degree such as travelling around the world and having a perfectly satisfactory family. Therefore, we can grasp that how essential a university education is according to the one’s dreams but university education is not essential for every dream. In addition, there are many other keys for success, such as the talents, intelligence, communication skills, social skills etc. To be successful in a career, we need those elements I mentioned above and cannot ignore their importance for success. The diploma is only just an admission ticket in our career. What the boss paying attention is not our level of education but our working ability. That’s mean the ability to get the project done in order to help the boss earning profit. Although one has a high education level, the boss would still fire him or her if he or she makes troublesome to the company. Therefore, the university education is not that essential as people think. In conclusion, the university education is only one of the key for success.

Senior Citizens Driiving - 1577 Words

Times are changing and the world is evolving. New technology and medications are constantly emerging and because of this it is no wonder that today people live an average of six years longer than they did in 1990 (Life Expectancy). With the life expectancy continually increasing, there are more and more elderly drivers on the roads. In fact, the total annual miles older drivers traveled climbed twenty nine percent from 1995 to 2001 (â€Å"Should elderly†) and that number is probably even greater now. This can cause a huge problem not only for the elderly drivers themselves, but for other people on the road too. As the body ages, reaction rate, hearing, and vision naturally decline which makes an aging driver much more susceptible to driving accidents and fatalities. Senior citizens should not be denied the right to drive, but they should be required to retake driving tests when they renew their license. This will confirm that they are mentally capable of operating a c ar and will assure more safety for all drivers on the road. In attempts to aid senior drivers even more, measures should also be put in place to make the roads easier for them to navigate. It is no secret that as people age their bodies start to slow down. Even though these changes are natural and extremely common, it does not mean they should be ignored, especially when it comes to driving. Vision, reaction rate, and hearing are three major concerns for elderly drivers. In the United States alone more
