This is a Study: How to Build a Bottle Rocket PDF Print E-mail

Rating 0.0/5 (0 vote)

Everything has to play somewhere. Would-be lift scientists with their eyes set on structure a shuttle to Mars might find that the understanding of their imagination is a structure off. But they can satisfy their desire to create something that flies through a fun and easy alternative enterprise: learning how to build a bottle rocket.
 
To commence how to flesh a bottle pyrotechnic, one would actually pauperism two 2-liter impressible soda bottles. The top and bottom part of one of the bottles are to be cut off, leaving only the cylinder-shaped middle section of that bottle. The cylinder must then be duct taped to the bottom of the other whole soda bottle. Aerodynamics is a significant factor in learning how to build a bottle rocket, so some care must be taken in designing the fins and the nose cone. The fins of the rocket will be cut out from a manila folder. There should be a total of three fins in all and they must be triangular in shape. They are to be attached to the rocket with the use of duct tape and each fin must be equally spaced apart from each other. The nose cone can be made from a small plastic athletic cone. The square-shaped bottom of the cone must be cut off. Putting a piece of clay the size of a golf ball inside the cone's tip will increase the cone's mass, thus giving it added inertia.

A piece of string with knots tied on both its ends for added friction is then to be attached to the bottle rocket, with one knotted end of the string to be taped inside the top of the rocket and the other knotted end inside the cone. The cone is then placed on the rocket, with the string inside it. To make sure that the cone comes off when the parachute is deployed, one may make a pedestal made up of three inverted fins (again made from manila folder) positioned right below where the cone shall rest. The parachute is to be made from a large plastic trash bag. First, the closed end of the bag must be cut off, after which the bag is to be folded in half lengthwise. It is then folded in half a second time, and then folded into a triangular shape with the closed end of the preceding fold as its base, followed by a second triangular fold. The excess material hanging out the triangle's base must be cut off. Once unfolded, the result should be two big circle-shaped plastic canopies.

One of the plastic circles is then to be folded in half, then in fourths and eighths, and finally to its sixteenths. Afterwards it is unfolded, and a piece of masking tape is placed around each crease mark along the circle's edge. Holes are then punched through each masking tape piece. The circle is folded in half and string is tied through the holes that had been made. The ends of the parachute strings are taped to the interior of the bottle rocket. The whole chute is loaded inside the rocket, and the cone is placed back onto the top. Once one has figured out how to build a bottle rocket, all that's left is to half-fill the rocket with water, set it up on the launch pad, pressurize it and finally fire it up (so to speak) for launch. Watching it blast off, it's amazing to think that that spiffy-looking missile shooting up into the sky was actually built using the simplest of materials.

Online Education as a Stepping Stone for Career Change and/or Advancement

I found this great article on Online Education and it is definitely worth checking out. Also, visit Online Courses to find great information on free online classes.

Online Education as a Stepping Stone for Career Change and/or Advancement

Q1: Who is the typical online student?

A1: Most online students are already taking face-to-face college courses. It was found that as many as 1 in 4 college students are taking at least one online course, a number that has probably increased today considering the substantial growth of online enrollments since 2008-2009, when that study was carried out. The seventh annual Sloan Survey of Online Learning demonstrated that of the 4.6 million students found to be learning online in the fall of 2008, a shocking 82% of these were studying at the undergraduate level. If you're an online graduate student, don't let this statistic make you feel outcasted. This number mirrors that of the distribution of all students in higher education, with undergraduates representing about 86%.  (Learning on Demand)

Q2: What is the typical online student looking for when he or she enrolls?

A2: There is a high demand today for college-educated workers, so many people are flocking to get those degrees, which will eventually get them higher paying and/or more flexible jobs. However, most of these people have pre-established lives, such as full-time jobs or families, so the idea of sitting in a classroom all day is just not practical. Online learning offers flexibility from the comfort of one's home or favorite coffee shop. With an online education, you can attend a course anywhere, anytime and course material is accessible 24/7. Students enrolling in online courses are also looking to participate in class, but maybe not in the traditional sense. Online learning  awards students anonymity, increasing their chances of participating actively and frequently. Most of us would be much more willing to state our opinion in a post on a wiki board than we would to speak out in a lecture hall in front of hundreds of other students.

Q3: What are the hottest online degrees today?

A3: The most popular online degrees today are business degrees, nursing programs, and criminal justice programs.  (US News & World Report)

Q4:  What new trends and innovations do you see in today's online education from the student, teaching, and technology perspectives?

A4: Schools knows that their students lead very different lifestyles, so are subsequently providing different options that fit these lifestyles. Many schools offer a blended or hybrid course, for which online and face-to-face delivery is mixed together and about 30 to 79% of the course material is delivered online. For these hybrid courses, you may meet your teacher once or twice, but most of the discussions take place on online forums.  (Learning on Demand) Instructors also realize that in the adult world, it is incredibly difficult to align schedules for groupwork outside of the classroom. Online learning circumnavigates this problem by providing chatrooms and newsgroups, on which students can meet and produce groupwork.

Q5: What is the best way to position an online degree when job searching and interviewing against candidates with offline degrees?

A5: Most employers know that if you earned a degree online, you did the same amount of work (or in some cases, maybe even more) as anyone else who earned that same degree face-to-face. However, there may be  some employers, for which you will be held at a disadvantage for obtaining an online degree. Thankfully, most employers are beginning to realize the value of an online degree because it takes an incredible amount of determination and discipline to receive one. To make sure that you avoid discrimination, make sure your online degree comes from an accredited college or institution. If it does, you should tote your online degree as proudly as you would any other degree.

An overview of the Internet phone and its process

In the following lines, what you are offered to read is about the latest telecommunication technology called VoIP or Internet Phone that was founded in year 1995. It all happened when a computer whiz generated audio connection between the computers. Following it, a software was launched in the same year enabling the users to talk to each other by using the modem, speakers, mic and sound card.

The analog voice is converted to digital form to make the communication between the speakers happen. The voice is broken down into pieces then assigned numeric values after then the data gets compressed. The following procedure involves the data’s division into packs that is then broadcasted over the Internet. At the receiving end, the data is identified and then added following the reconstruction to make the voice takes place.

By the year 1998, Internet phone service started to become popular. At that time, the gateway has emerged into the field that allowed the computer to make connection with the phone. The technology then got widened by establishing a phone-to-phone connection with the use of Internet in the same year. The computer was still in need to make phone-to-phone connection to begin the call. But the moment the connection got through, a regular handset could be used. In today’s scenario, you no longer need any computer at all. What you require to use the Internet phone is a phone, adapter, high-speed Internet connection and Internet phone service. The phones set makes a connection with the adapter that is then connected to the Internet sans any use of computer at all. In order to have the brilliant voice quality and the usual features that come along with the service like call waiting, a user will have to sign up with a VoIP service provider. The market is filled with the VoIP providers, so you should make a through research before signing up with the one.

Modern Technology Makes Education so Easy

Kids don't often ponder train to be 'cool' or 'bodoni.' Most of us remember school as sitting in a desk covered in 20-year-old ornament while reading from a history text book that stopped at the Cold War. Whether a result of a lack of funding or the administration's aversion to change, schools are rarely considered to be on the cutting edge of technology. Yet more school administrators are realizing the educational benefits modern technologies offer students. This attitude shift began with the introduction of the Internet in the 1990s. The Internet's possibilities in terms of learning and education were quickly realized, and computers with Internet connections soon became widely adopted by many school systems.

Integrating Science and Technology

We begin with the line tool to cut the screen into quadrants. Then with the alphabet stamped we put one season name into each quarter. With the "wacky paintbrush" bare branch trees can be added to each section. Eventually, using the spray can in the "wacky paintbrush" tools we can add the appropriate leaves to each area. Lots of colours for the autumn trees. No leaves for winter. Bright green leaves for the new emerging leaves of spring along with some pink for all the flowering trees, and then full green for the summer.

The Enactment of Technology in Education

Technology has become an important component in the current age we live in. Every day there is some new gadget or software that makes lives easier and improves on the technology and software that already exists. Making lives easier is not, however, the only role technology plays in our lives. Technology is playing an increasing role in education. As technology advances, it is used to benefit students of all ages in the learning process. Technology used in the classroom helps students adsorb the material. For example, since some people are visual learners, projection screens linked to computers can allow students to see their notes instead of simply listening to a teacher deliver a lecture.
