Hundreds of thoughts swarm through my head, as I think of potential car and launcher designs. It was the beginning of 8th grade. A new year of middle school, a new year of Science Olympiad, a new year of studying for my events, and a new year of challenges: my first building event, Scrambler. I’ve always been interested in science, specifically medicine, ever since I was 7 or 8. I read a book called When I Grow Up, I Want to Be a Doctor, which inspired me to aspire to become a doctor. Ever since then, I’ve been exploring the field of science and medicine through a variety of learning experiences such as Science Olympiad, a science competition consisting of several events that cater to a variety of fields in science. This year, my partner and I were faced with the task of building a mechanical vehicle, powered by a falling mass, that is capable of traveling down a straight, level track with a barrier at the end while carrying an …show more content…
egg mounted to the front. Our vehicle must stop before the barrier so the egg won’t crack. This problem seemed daunting at first, but we immediately started working. We carefully planned our launcher and car to the last detail.
“How about we use a pulley system with a weight at the end to push the car forward?” my team member suggested. “Or we could use a hammer launcher,” I proposed. We went back and forth, contemplating different methods. We faced trials, tribulations, and troubles in the design process. Building and perfecting our designs took weeks, but our coach guided us throughout the process and encouraged us to “Never give up!” We researched the effects of different factors that could potentially come in the way of our success and analyzed all of the device possibilities. Even when research got arduous and we couldn’t agree on something, we never gave up on our dream of placing in the regional competition. This was one of the hardest challenges I’ve ever faced in my Science Olympiad career, but our unfaltering dedication and our belief in success helped us persist in the face of setbacks. Once we finished our plan, we began to build the device. It was exhilarating to see our plan come to
life. First, we started building our launcher. Our launcher consisted of rough, brown wood that formed the base. We carefully nailed it together. It was like two upside down flags connected together by rods. The three rods were scattered throughout the launcher, on the top, bottom, and middle. There were two pulleys on each rod. On the back of our launcher was a piece of PVC, and inside it was our falling mass, rested on a thin, yellow pencil, that was stuck through two holes in the PVC. Attached to the falling mass was a very long piece of string, that wrapped around the meticulous, intricate system of pulleys. Then we built the car. We made a vertical dowel that the string was looped around. The car was composed of a sleek, metal base with three long rods, two on the front and one on the back. Attached to the front two rods was our braking system: a bolt and a wing nut. When the car moved, the axle will turn and the wingnut will hit the bolt and stop the axle. On the ends of the rods were shiny, plastic CD’s covered in two layers of gloves, that functioned as wheels. The CD’s were bolted to the rod and slightly crooked. Finally, at the front of the car were two dowels to hold the egg. When the pencil was pulled, the falling mass fell inside the tube, pulling the string, and pushing the car forward, like a chain reaction. Our car and launcher were carefully planned out and hypothetically made sense and the next step of the process was to test it. Consequently, we tested our launcher and car several times.We tested the device several times to ensure it’s accuracy. We had to incorporate and perfect several factors, such as the length of the track and barrier, the angle of our car and launcher, and the speed of the car. It was very inconsistent, some days it would work and some days it wouldn’t. My partner and I were frustrated, and our device broke several times. It was a continuous cycle, we tested it, it broke, we fixed it, and so on. It seemed like we would never progress to the competition. After months of testing, the day before the regional competition came along. We rushed to grab our launcher and car after school and immediately began testing. We didn’t stop testing until we got consistent results. Finally, at around nine at night, we felt confident in our car and launcher and we were ready to compete. It seemed as if our system magically started working consistently. “Finally!” my partner and I exclaimed with triumph. The next morning at the competition, we entered the gym and sweat dripped down our faces. “Mills Park Middle Varsity” the event leader called. We slowly walked up to the testing hallway. Along the hallway were pieces of painter's tape, that looked miles and miles long to us, but in reality, were a mere 10 meters in length. At the end was the barrier, a piece of wood that was about 3 feet tall. And it was completely dry. Nerves chilled down my spine. Did anyone’s egg hit the barrier? I thought to myself. “Your time begins now” the event leader called. We had 8 minutes to run this device twice. 8 minutes to showcase what we have worked on for months. 8 minutes to make or break everything. Like machines, we systematically set up the device at an abnormally fast speed. Something didn’t feel right. We launched the car and it was by far the worst I’ve ever seen it. It missed the barrier and went tilted. But we had one more shot. We set up the device again. Just as I was about to launch it, I looked around. I saw the other teams watching us, waiting for us to fail, waiting for us to crack the egg, waiting for our demise. I looked at the event leaders, noting our failures and looking for any reason to disqualify us. Just do it! I told myself. I nervously pulled the pencil. The car raced out, like a cheetah being released from its cage. It abruptly stopped about a foot away from the barrier. We walked up to the car and it went straight on the center line. Our jaws dropped to the floor. We were flabbergasted. But, now we had to wait for our placement. We walked to the gym where the awards ceremony took place. We sat down and listened as they called each event in alphabetical order. Every time somebody won an award, cheers and screams lit up the gym as the competitor raced down the bleachers to grab their medal. I hoped that would be me. “Disease Detectives, Division B” the announcer called. My second event. I trembled with fear as they didn’t call our name for tenth, ninth, eighth, seventh, sixth, fifth, or fourth place. Did I make top three or did I not place in the top ten? I thought to myself. Then the words uttered out of the announcer’s mouth. “Third place goes to Mills Park Middle!” I raced down the bleachers to grab my medal. It was laced with white ribbon and gleamed as the volunteer put it on my neck. Soon after that, the announcer called out “Road Scholar, Division B”, my third event. I gleamed with pride when they called me for first place and I retrieved my purple laced gold medal. I quickly got back to where our team was and was greeted with high-fives and proud cheers. But Scrambler was yet to be called. Finally, after about half an hour, the announcer said “Scrambler, Division B.” We winced in pain when we weren’t called. We failed. Even though Mills Park achieved first place in our division and our whole team advanced to states, we felt unhappy. “Don’t be sad guys, just try harder for states!” our coach said, trying to cheer us up. On the following Monday, we came to school with good and bad news. “Here’s the good news,” our coach told us, “There were scoring errors and you guys actually got fifth place in Scrambler!” I almost screamed with joy. “But here’s the bad news, Road Scholar didn’t get first, you got twelfth and Mills Park Middle didn’t get first, we got second.” A mix of emotions swarmed through my head: anger, frustration, and joy. How could they take first place from us? I felt like Miss Colombia after her Miss Universe title was taken away. But this fueled me to try harder at the state competition. I worked on my three events for months. I also took on two more events so I studied a lot for my five events. When the state competition came, I felt ready for all five of my events. Scrambler was at the end of the day so I took all of my tests before then. We tested our Scrambler car and we performed about the same as the regional competition. “Will this be good enough to place here at states?” my partner asked. “Hopefully,” I assured him. At the awards ceremony, I placed in two out of five of my events. I placed second in one and fourth in the other. But, we didn’t place in Scrambler. We felt dejected that we didn’t place in the top ten, but sanguine because of our achievements at the regional competition and the fact that we placed in other events. At last, my final year, as a participant, in middle school Science Olympiad was over. Now, I am in my freshman year of high school. Surprisingly, I made the varsity team on the PCHS Science Olympiad team. I learned from my experience and my mistakes in 8th grade. I learned not to leave anything for the night before the competition and try not to procrastinate. Also, I learned to persist in the face of obstacles and find a way around setbacks. Now, I share my experiences with middle schoolers as I coach the MPMS Science Olympiad team. Recently, we competed at our regional competition and my partner and I placed first in our event, Disease Detectives. I am eager to go to the state competition this year, my first year competing as a high schooler. Before Science Olympiad, I had never experienced failure and getting back up from it. But now, I have learned that failure is not the end and growth is more important. I now have a growth mindset and I work around obstacles. Throughout my Science Olympiad journey I have learned that even if you fail, as long as you persist, you will reach your goal.
There are three safety features in the egg project. The three safety features are seat belts, brakes, and airbags. The seat belts are made out of tape. The seat belts put pressure on the passenger. This means that it will keep the passenger inside the car instead of flying out and getting injured. The airbags are made out of bubble wrap. The bubble wrap will have a huge impact on the area of the passenger. It is like a soft cushion. This protects the passenger from hitting the passenger. The passenger will get hurt by the airbag, but not as much without one. If there wasn’t an airbag in a car, people would be getting into a second collision. A second collision is where the body hits the car. That is the whole point of an airbag. The brakes are made out of cotton balls. The brakes prevent the passenger from getting hit and it puts force on it. Also, they prevent it from getting into a first collision. A first collision is where a
The word demolition means collisions and hitting two objects together while derby mean a race. These two words put together creates a competitive place for people to enjoy derby cars. Demolition derby drivers come from long family history of drivers. The pasion starts when they are old enough to walk, helping dad at the garage. He can remember their first demolition derby going forty miles per hour, smashing into another car and coming in third. From that moment on, he was hooked. From my experience and research, I know there is a lot of time and effort that goes into building the car, participating in the demo derby, and keeping a driver and spectators safe and these are the three areas of focus on in this paper.
Different collisions took place throughout the process of the Rube Goldberg Machine. This included Elastic and Inelastic collisions. An example of an Elastic Collision in our Rube Goldberg Machine is when the car went down the track and collided with another car. Elastic collisions are defined as collisions with conservation or no loss of momentum. This is proven by the first car which transferred its momentum to the second car thus momentum was perfectly conserved. An Inelastic Collision is seen in our project ...
Rolling a Car down a Ramp Investigation PLANNING When planning my experiment, I will need to take into consideration. the following points: -Fair testing -Equipment -How many results will I get? -What range of variables I will experiment with I will be investigating, by varying the height of the summit of the ramp. is raised off the ground, if the average speed increases or decreases.
I’m so happy to be given the opportunity to join National Junior Honor Society(NJHS). I would love to be a member. I think it is important for kids to be involved in the community. Also, myself personally it would be an honor to be a face for our school.
As a student at Northvale Public School, I have grown up with my older siblings being inducted into an organization called the National Junior Honor Society. I had seen all the hard work and dedication they put into their school work and activities just to get into this society, making me want to be just like them. Then a few weeks ago, I found a note on my desk in homeroom telling me that I had been nominated to be apart of this society. Through citizenship and character, leadership, and service, I intend on being inducted into the society I have heard so much about. Though it will take a lot of effort this school year, being a part of this society is a dream of mine that I will make sure to come true.
People say high school is supposed to be the golden years of your life. I don’t know what else in life is to come; however, my philosophy is to live in the moment and make the life you’re living in the present worthwhile into the future, not only for you but for those who surround you. I live my life participating in our community and getting involved in our school. The activities, and the people I’ve formed relationships with, are what have formed me into the person I have become today. The person I am today is not perfect, but I have learned from the mistakes I’ve made. I think the sense of maturity I have developed throughout my life has given me the determination to be the best person I can be. That being said, I would love to be inducted into the National Honor Society and not only represent our school, but represent our generation to the community not as a “selfie” generation but as a generation, with great potential.
Newton’s 2nd Law of Motion states that acceleration is directly proportional to net force when mass is constant. This experiment dealing with variable forces has as its objective the verification of this law. In this experiment this law is tested for verification in straight forward way. Through the use of a Force Sensor and an Accelerometer, data collection of observations and measurements that a force exerts on a small cart along with the cart’s accelerations are to be determined. The sensors’ measurements will be employed to give meaningful relationships between the net force on the cart, its mass, and its acceleration under these conditions. The resultant measurements revealed will verify and determine the force and acceleration relationship as stated by Newton.
The move toward a more aggressively styled and higher riding vehicles have caused unintended consequences and risks. The risks include decreased “drivability”, obstruction of vision, and concerns surrounding safety. Current trends in vehicle design focus on addressing these problems to achieve appealing designs with the best qualities of both cars and trucks, as seen in all the new designs from the Land Rover.
Being a member of the future generation of innovators and leaders, I feel that this research combined with my fascination of automobiles could lead to a clearer understanding of how I can help improve the automobile. In a world that is highly connected by roads, if the problem of using petroleum-based fuels is not solved, the entire gas-guzzling world could come to a standstill. This apocalyptic halt would cease all travel and we would be thrown back to a more primitive standing. However, if we research and find an alternative ahead of time, we would be able to transiti...
The Special Olympics play an important role in the lives of people with disabilities all over the world by making them feel like they can have a normal life. The Special Olympics helps people with disabilities experience this by allowing them to participate in sports and different activities that they otherwise wouldn’t be able to because of their disability. Although the Special Olympics is meant to help everyone with disabilities their website only shows those with intellectual disabilities participating in what they have to offer. By doing this they don’t achieve their overall effect of showing that everyone with disabilities can come and participate in the Special Olympics without having to feel that they’re any different than those around
Even Steve Jobs predicted that cities would be built around it. So, what went wrong with that? In this essay, the reasons why Segway didn’t do a better job in anticipating the issues that will face the project will be explored. Being a technological piece of art and mechanically robust, sales expectations were high. Segway was predicted to be the fastest company in the open era to hit $ 1 billion dollars in sales and they were so optimistic they erected a 77,000 square feet factory that can produce around 48,000 units per annum with an average price of $ 5000.
The Olympic Games. The biggest international sports competition in which the worlds’ best athletes compete from all around the world to win medals for their countries. The Olympics have been a worldwide tradition since the eighth century BC, but it has hardly benefited us as a species. Every time we have the Games, our resources are abused in order to create the Olympics we desire. Huge amounts of money are used to build venues and make medals, only leading up to the countries who host the Games going into debt afterwards. There are only rare cases in which the countries earn money from hosting the Olympics, but most of the time the debt that they get themselves into take years, or even decades to pay off. You might ask yourself, why do we even host the Olympics, if it has these huge disadvantages? The answer is because we want pride for our countries, no matter how temporary it is. Knowing this, we can safely say, that the Olympic Games do not help us grow as a species.
While building my water bottle rocket, I discovered a bunch of plastic, cardboard, and water could be complex. The connectivity and relationship of all the engineering disciplines intrigued me, waking up a voracious feeling of learning them. Different concepts, such as aerodynamics, the properties of water, and physics, could be used along with SOLIDWORKS, or computer modeling, to 3d print the nozzle. Every different engineering discipline can come together to result in one marvelous outcome, a successful launch. Challenged by our classroom competitions, I was delighted to surpass the teacher’s expectations.
