Understanding the Scientific Method - Understanding the scientific method and how to follow it is critical to building a good reputation in the technical community. In regards to science fairs, as a student progresses in grade levels the judges are going to demand more and more focus on using the scientific method. Here is my seven step description of the scientific method. 1. Define the question 2. Gather information and resources 3. Form hypothesis 4. Perform experiment and collect data 5. Analyze data 6. Interpret data and draw conclusions that serve as a starting point for new hypotheses 7. Publish results In science fair competitions, if you can show that you are following the scientific method, you are well on your way to impressing the judges. Basically, start out by defining your question and topic. After that, form a hypothesis and perform your experiments. Step 6 is where you use that data to make any new hypotheses or theories about your science topic. If you want, you can ...

The Invisible Ether and Michelson Morley - The concept of the invisible ether or 'aether' is an old concept dating to the time of the ancient Greeks.  They considered the ether as that medium which permeated all of the universe and even believed the ether to be another element.  Along with Earth, Wind, Fire and Water Aristotle proposed that the ether should be treated as the fifth element or quintessence; this term which literally means 'fifth element' has even survived down to the present day to explain an exotic form of 'dark energy' which is crucial in some cosmological models.  These ideas spread throughout the world until the advent of a new springtime in scientific thought.  The first person in the modern era to conceive of the idea of an underlying ether to support the movement of light waves was seventeenth century dutch scientist Christiaan Huygens. Many others followed in expressing their opinions on the ether concept.  Whilst Isaac Newton disagreed w...

The Fossil Record And Creation Science - The Fossil Record And Creation Science - Young earth creationists commonly point to the fossil record in order to support their position. In one instance, the article "The Fossil Record: Becoming More Random All the Time" by John Woodmorappe, has some very good points to it (Footnote 1). Read it if you like, (its a long one), but you don't have to much farther than the abstract to see problems. Actually, some are problems, and some are deceptions. The abstract states that "The reality of the geologic column is predicated on the belief that fossils have restricted ranges in rock strata." Of course it is...this has been the "reality" all along. His wording makes it sound as if the geologist has been up to some deceit...but this is not the case. He goes on to claim, "as more and more fossils are found, the ranges of fossils keep increasing." Welcome to the world of science! This is nothing new. As new di...

Sodium Vapour Lamp - Sodium Vapour Lamp consists of a discharge tube made from a heat resistant glass, containing a small amount of metallic sodium, neon gas and two electrodes, Neon gas is added to start the discharge and to develop enough heat to vaporize the sodium. Because of law pressure inside the tube, a sufficiently long tube required to obtain more light. To reduce the overall dimension of the lamp, this tube is generally bent into U-shape. The light produced by this lamp is yellowish which is produced at its optimum pressure of about 0.004mm of mercury. This pressure is obtained at a temperature of about 280° C and so it becomes necessary to maintain this temperature. For this purpose the U-tube is enclosed in a double walled flask to prevent lose of heat. The double walled flask is interchangeable and can be fitted on to another U-tube. While replacing the inner U-tube one must be very careful because if it is broken and sodium comes in contact with moisture, it may result ...

Shun Cloning : Scientists Must Speak Out - Scientists say evidence is mounting "that creating healthy animals through cloning is More difficult than they had expected." So began a front-page story in the New York Times (Marching 25), highlighting the frustrations of animal cloners, and the chance that person cloning whitethorn prove technically inconceivable. Those worried about the ethics of individual cloning have greeted this as good news, a sign that the slippery slope is leveling come out of the closet. Unfortunately, the new obstacles English hawthorn prove less than insurmountable in the hanker tally--and in bioengineering, the yearn running often proves surprisingly short. For those whose doubts about ergonomics ar expressed by the philosopher Leon Kass as "the wisdom of repugnance," it is no meter to relax: The slope Crataegus laevigata soon steepen once Thomas More. In cloning, a cellular cell nucleus from the grownup to be cloned is injected into an test...

Saving The World With Forensic Science - Forensic Science is the application of science in forensic studies, the forensic part of forensic science implies that it is to be utilized in some form or another with a court of law and is relevant to legal proceedings. Forensic Science is rapidly progressing to the point that the science fiction of today could well be the science reality of tomorrow. Forensic Science has been around for many centuries. However, it was not until recently that advances in scientific research and scientific studies made this a true and individual aspect of forensic research. Recent studies and research have brought the field of forensic science to new heights and given it increasing credibility and importance as a deciding factor in many legal proceedings, where forensic evidence often outweighs the testimony even of witnesses on the scene. Almost everybody has heard of DNA evidence or fluorescing as well as many other recent scientific developments in forensic...
