Balloon Car Research Paper

In this project, we had to make a car that had at least three wheels and could only be powered by a balloon. The first step was to create a design, I had started by creating a design but, rethought the design throughout the days we were allowed to work on the car in the class. My final car was inspired by other students but, I changed the car to have three wheels instead of four. I then used CD’s as the wheels and taped the balloon to multiple straws to keep it in place. Then, two sticks taped together as an axle to allow the straws and CD’s to move freely but connected to the car. Then I joined the parts of the car and made it into a triangle shape. When thinking about where to put the balloon I realized I needed to add height so the balloon would not be able to touch the wheels and make it stop moving. So I taped two popsicle sticks to the two connecting sticks, then to connect the popsicle sticks together I added a third and taped the balloon with a straw inside to the top popsicle stick. My car did travel and move when some others throughout the classes did not. The three runs distance in order was One …show more content…
This is because as the air pushes out of the back end of the balloon it pushed the car forward in the opposite direction with the same amount of force. This project also uses both friction and momentum. These were both factors in the races, another factor in the race was weight because the heavier the car means the more force you would need to allow the car to move and give the balloon having the greater force. After, watching the other cars race to improve my car I could have made a better support for the balloon and blown the balloon up to its maximum mass or size giving the car the most. Finally, I believe this project was a good opportunity to see Newtons third law in action and what roles friction and momentum can play in this

Interface Design for Computer-Based Learning Environments

...of Georgia [pic] Research in the area of user interface design for computer-based learning environments (Jones, 1993) found that screen and interface design should be considered at the same time during the design and development process. Additionally, the research produced a list of interface design concepts and a corresponding list of guidelines for implementing those concepts. The concepts presented in this paper are broad issues to be considered during the design and development process. The guidelines that are associaàted with the concepts are intended to be flexible, and allow for the creativity of the individual designer, and the needs of a particular project. Names for some of the concepts were taken from an analysis of the literature in computer-based instruction (CBI), computer-based learning environments, and human computer interaction (HCI). Names for the other concepts were emic categories generated by the participants in the study. The guidelines were derived through an analysis of the literature, an analysis of six commercially produced computer-based learning environments, and interviews with the designers and developers of the six computer-based learning environments. Further research is being conducted to determine how designers and developers can implement these guidelines. If you are interested in either the progress of this research or discussing the issue of user interface design further, please contact the primary author of this paper at: MGJONES@NIU.EDU...

...Forces and Motion For Students of Baldwin Wallace College Spring Semester 2011 Monday – Wednesday 10:00 – 11:15 am Room 139 Wilker Faculty Richard Heckathorn The materials for this course were organized and edited by Richard Heckathorn using materials from a program called Operation Physics and includes materials developed by him. The original OPERATION PHYSICS activity sequence to improve physics teaching and learning in upper elementary and middle schools was funded by the National Science Foundation. Original Material Copyright 1992 by American Institute of Physics Materials edited and photoduplicated with permission. FORCES & MOTION INTRODUCTION WORKSHOP LEADER’S TOPIC INFORMATION INTRODUCTION TO FORCES & MOTION An understanding of force and motion is fundamental to the study of almost all other physics-related topics. Yet it is a topic often overlooked or only cursorily introduced in elementary and middle school science, even though it is a topic typically identified for inclusion in the curriculum for these grades. A primary reason for this is that many teachers do not feel comfortable about their own understanding of the topic. Consequently, this may be the most needed of all of the OPERATION PHYSICS workshops. This workshop leader’s notebook is divided into two parts: PART ONE Motion Part One begins by introducing participants to the concepts of space and time....

The learners have also discovered that cells divide to produce new cells by mitosis and meiosis. They have understood that meiosis is an early step in sexual reproduction that leads to variation. Students have been introduced to genetics to be able to appreciate evolutionary differences among species. Learners have also found out that biodiversity is the collective variety of species living in an ecosystem, and by studying the ecosystem; they have come across the various cycling of materials and energy transformation. DRAFT April 29, 2014 All modules in Grade 9 Unit 1-Living Things and Their Environment present student-centered activities that will allow the learners to discover and develop concepts that they may consider useful to their everyday life. At the end of each lesson, key concepts are provided for the students to grasp ideas and information that they will remember even after they have left school. Instructional activities are designed to build up the students’ knowledge, understanding, skills, and ability to transfer...

Automatic Breking

...Jakobsson Henrik Lind Magdalena Lindman Volvo Car Corporation Sweden Paper Number 07-0450 ABSTRACT Automotive safety has gained an increasing amount of interest from the general public, governments, and the car industry. This is more than justified by traffic accident statistics, as each year around 1.2 million people die due to road traffic accidents. For these reasons safety remains a core value of Volvo Cars. This paper presents some of the latest active safety developments within Volvo Cars. Rear-end collisions are common accident scenarios and a common cause of these accidents is driver distraction and thus not reacting in time. No vehicle system is a substitute for the most important safety feature in any vehicle: the driver. However, Volvo is harnessing innovative technologies to help alert drivers to avoid potential collisions and reduce the potential impact speed when a collision cannot be avoided. One of those systems is Collision Warning with Auto Brake where the area in front of the vehicle is continuously monitored with the help of a longrange radar and a forward-sensing wide-angle camera fitted in front of the interior rear-view mirror. A warning and brake support will be provided for collisions with other vehicles, both moving and stationary. Additionally, if the driver does not intervene in spite of the warning and the possible collision is judged to be unavoidable; intervention braking is automatically applied to slow down the car. This aims at reducing impact speeds and...

Geoengineering Research

...How Geoengineering Works: 5 Big Plans to Stop Global Warming At first blush, geoengineering sounds like outrageous junk science. Surely there's an easier solution to the problem of global warming than technologically altering Earth's atmosphere, its cloud formations and even outer space. But when compared with the alternativedrastically reducing the amount of carbon dioxide blanketing the planet by changing the behavior of billions of people and thousands of industries, not to mention slow-moving governmentssome scientists are beginning to take the seemingly outrageous schemes a lot more seriously. Here are the mechanics behind five plans to jury-rig the Earth. 1. Copy a Volcano (Photograph by Tarko Sudiarno/AFP/Getty Images) A volcanic eruption can bellow many million tons of sulfur-dioxide gas into the atmosphere, creating a cloud that blocks some of the sun's radiation. By injecting the atmosphere with sulfur, some scientists believe they could likewise block solar radiation and potentially cool the planet. Sulfur dioxide reacts with water in the atmosphere to create droplets of sulfuric acid, says Rutgers University environmental scientist Alan Robock. Those droplets are particularly good at scattering the sun's light back out into space. And because sulfur doesn't heat the stratosphere as much as other aerosols, it wouldn't work against the cooling effect. Hydrogen sulfide is an even better candidate for atmospheric seeding than sulfur dioxide, but scientists would...

Allan Poe

...Comics as Archives: MetaMetaMaus Hillary Chute | University of Chicago Abstract: In the view of some critics, the form of comics is a locus of the archival, a place where we can identify an archival turn. Art Spiegelman’s Maus first and perhaps most forcefully established the connection between archives and comics. His groundbreaking work documenting his father’s experience in WWII Poland, where he survived internment in Auschwitz, is a visual narrative based on oral testimony that consistently heightens our awareness of visual, written, and oral archives, and where they interact, overlap, or get transposed one into the other. Hillary Chute recounts and interprets her collaboration with Spiegelman in the process of assembling MetaMaus, a book compiling interviews and archival materials on the making of Maus. MetaMaus, argues Chute, reflects the tension between different kinds of extant archives—oral, written, photographic—and the cross-discursive work of (re)building new archives that motivates Maus. Its defining feature is that it shows the materiality of Spiegelman’s archive; it is about the embodiment of archives. The subject of Maus is the retrieval of memory and ultimately, the creation of memory…. It’s about choices being made, of finding what one can tell, and what one can reveal, and what one can reveal beyond what one knows one is revealing. Those are the things that give real tensile strength to the work—putting the dead into little boxes. – Art Spiegelman (MetaMaus...

Xeco 212 Final Project: a New House Decision

...XECO/212 October 30, 2011 Chiara Yates Final Project: A New House-Decision Many of our decisions are influenced by the state of our economy. Purchase of big ticket items such as appliances, furniture, autos, and a home follow a line of investigation before the decision to purchase is implemented. The purchase of a home is one of the largest investments made in a lifetime, and uses many factoring influences before purchase. This paper will show how economics plays into the decision of the purchase. One of the first areas to consider is what the trade-off will be in purchasing a home versus the benefit of renting. What we need to consider is if purchasing a home and providing more space, and living closer to shopping and schools, justifies the added cost in utilities and maintenance of a home. The opportunity costs are another factor to consider. We can vacation closer to home instead of the trip to Europe we had hoped to take. Another option would be to maintain our existing auto instead of buying a new car. We need to research the marginal costs we would need to pay out. These include the amount of down payment, closing costs, taxes, insurance fees, and moving expenses. If we rent a larger apartment, we won’t have those costs, but we also wouldn’t have the benefit of ownership/write-off of interests in loan and property taxes. Monthly rent costs may be as much for a larger apartment versus a home that could be smaller than a rental, but we would own the real estate...

Globalization

...discusses what we believe are the main risks posed by globalization to the automobile industry. We define globalization for the purpose of this essay to beas the integration of markets across political boundaries that allows for the flow of capital, people, goods and services within. We define the automobile industry as the set of companies that produce automobiles and light duty trucks (“The Auto Industry”).. Since WW II, globalization has enabled greater market access and corporate consolidation that has enabled large automobile manufacturers to diversify their offer product and transcend national boundaries. Volkswagen, for example, originally a German company founded by Nazi government in 1937 to offer German citizens a German produced car, now includes makes from seven different countries and has hails China as one of its largest markets with an 18.6% market share at the end of 2008 (Volkswagen, 2008); and Tata, the Indian conglomerate owns two venerable English brands, Jaguar and Land Rover. While the automotive industry has grown and thrived as a result of globalization, it also has, and will continue to face risks that if left unattended, will negatively impact both industry growth and profitability. These risks are:...
