http://www.articlesphere.com/Category/Science/205 Science articles from ArticleSphere.com Rss Follow Up Sat, 04 Jul 2009 17:41:33 -0700 Doing well in HSC sciences requires a slightly different approach than HSC maths or English subjects. HSC sciences, like Chemistry, Physics and Biology, place a heavy focus on the syllabus. Detailed knowledge and familiarisation of the syllabus is very important. http://www.articlesphere.com/Article/How-to-Do-Well-in-the-HSC-Sciences/186779 Mon, 18 May 2009 00:00:00 -0700 http://www.articlesphere.com/Article/How-to-Do-Well-in-the-HSC-Sciences/186779 First we should say: do NOT cram if you have a choice. We do not recommend cramming as a sole solution to the HSC, as cramming definitely underperforms consistent study in the long run. However in life, unforeseen events happen and you may find yourself in a situation where you have only a few days, or even just 1 day, before a major exam. http://www.articlesphere.com/Article/Crammers-Guide-to-Survival-in-HSC-Exams/185033 Thu, 16 Apr 2009 00:00:00 -0700 http://www.articlesphere.com/Article/Crammers-Guide-to-Survival-in-HSC-Exams/185033 HSC Physics can be one of the most rewarding HSC subjects that is widely and commonly available across schools in NSW. HSC Physics tends to appeal to students with an interest for quantitative subjects like mathematics. In fact, if one is to try to define physics, it would be applied 2 unit maths. The mathematics in physics is certainly not difficult, but the problems in Physics are structured in terms of real-world applications. http://www.articlesphere.com/Article/HSC-Physics/183418 Fri, 27 Mar 2009 00:00:00 -0700 http://www.articlesphere.com/Article/HSC-Physics/183418 How much do you know about industrial magnets? Did you know that many of the goods we use on a daily basis are produced in manufacturing facilities that utilize some type of industrial magnet? In this article, we'll explore some of the many uses of industrial magnets and the ways they are improving manufacturing processes every day. http://www.articlesphere.com/Article/Industrial-Magnets--Their-Many-Manufacturing-Uses/181606 Thu, 12 Mar 2009 00:00:00 -0700 http://www.articlesphere.com/Article/Industrial-Magnets--Their-Many-Manufacturing-Uses/181606 The Hoover U8188900 Anniversary Wind Tunnel Bagged and Bagless Upright is nicely priced in the $200-$250 range. This machine utilizes Wind Tunnel Technology (semi cyclonic) and can be used as a bagged or bagless vacuum cleaner which makes it perfect for larger debris jobs as well as normal vacuuming. http://www.articlesphere.com/Article/Hoover-U8188900-Vacuum-Cleaners-Review/177600 Sat, 14 Feb 2009 00:00:00 -0800 http://www.articlesphere.com/Article/Hoover-U8188900-Vacuum-Cleaners-Review/177600 There is always something new happening in the world of science. In fact, there are so many new scientific discoveries and inventions, that its virtually impossible to stay abreast of all the new information. Here are a few really cool new inventions that are under development. http://www.articlesphere.com/Article/The-Latest-Scientific-Inventions-and-Cool-New-Research/177597 Sat, 14 Feb 2009 00:00:00 -0800 http://www.articlesphere.com/Article/The-Latest-Scientific-Inventions-and-Cool-New-Research/177597 NASA launched spaceship Endeavour Friday night at 7:55pm EST and I was in Cape Canaveral, Florida to see it! It certainly did give me perspective looking out several thousand miles, seeing the ball of light called Endeavour slowly evaporate into outer space. We all bade the seven NASA astronauts "safe travels" and "come home safe"...those were the uniform wishes from all those gathered. http://www.articlesphere.com/Article/Launching-Endeavour/177417 Thu, 12 Feb 2009 00:00:00 -0800 http://www.articlesphere.com/Article/Launching-Endeavour/177417 With our Planet, and our childrens future, going down the pan we need Alternative Energy Options and we need them Today. It may already be to late, but what will our kids, and their kids, think of us if we dont at least try? It must be today. Alternative Energy Sources have been examined for years now. Its about time we saw a significant announcement about the immediate implementation of Alternative Energy Options. http://www.articlesphere.com/Article/The-Planet-is-in-Danger--Alternative-Energy-is-our-Only-Choice/176581 Fri, 06 Feb 2009 00:00:00 -0800 http://www.articlesphere.com/Article/The-Planet-is-in-Danger--Alternative-Energy-is-our-Only-Choice/176581 So who do you think built the pyramids of Egypt? Is it as the modern day archaeologists who have to answer to their Christian and Jewish financiers and their Egyptian Muslim hosts say. That they were built by the hands of ancient Egyptians some 5,000 years ago. A huge job that would have required that a twenty ton block be set in place every three minutes for at least twenty years! http://www.articlesphere.com/Article/Stargate-Worlds--Is-It-Leaning-Towards-Science-Fact-/173447 Mon, 12 Jan 2009 00:00:00 -0800 http://www.articlesphere.com/Article/Stargate-Worlds--Is-It-Leaning-Towards-Science-Fact-/173447 Magnetism was discovered thousands of years ago, and magnets have been used for many purposes ever since. However, there is a great deal of mystery and controversy surrounding the discovery of magnetism. We'll explore some of the various legends about magnets, including how they were discovered and some of their first uses. http://www.articlesphere.com/Article/The-History-and-Legend-of-Magnets/172687 Mon, 05 Jan 2009 00:00:00 -0800 http://www.articlesphere.com/Article/The-History-and-Legend-of-Magnets/172687 Many of us know very little about magnets. We recall basic science experiments from elementary school, designed to teach us about the basics of magnetism. Some of us might recall that magnets have two poles. But for many people, we don't contemplate magnets in our daily lives, nor are we even aware of what a large role they play in our world. http://www.articlesphere.com/Article/Magnet-Technology/171916 Fri, 26 Dec 2008 00:00:00 -0800 http://www.articlesphere.com/Article/Magnet-Technology/171916 Newly, the Planetary Society called for main changes in US space exploration tactics. Distinctively, it suggested bypass the Moon in favour of Mars. The only scientists, Harrison Schmitt to have walked on the Moon resign from the society in complaint. http://www.articlesphere.com/Article/Why-NASA-have-to-focus-on-the-Moon--not-Mars/171031 Tue, 16 Dec 2008 00:00:00 -0800 http://www.articlesphere.com/Article/Why-NASA-have-to-focus-on-the-Moon--not-Mars/171031 Did you know that magnets can actually help your health? Many of the incredible advances in modern medicine can be credited to the use of magnets. We'll explore some of the ways that magnet technology is improving the way we treat patients. http://www.articlesphere.com/Article/Magnet-Technology-and-Health-Care/167451 Tue, 18 Nov 2008 00:00:00 -0800 http://www.articlesphere.com/Article/Magnet-Technology-and-Health-Care/167451 The main research revolving around adult stem cells is that they have the ability to divide and self-renew indefinitely. This means that with the right research, adult stem cells could be used for all sorts of things. They are already more than valuable in research, particularly those which have cures that seem to be far away and hard to find. The adult stem cell, which has the ability to become any other type of cell in the body, might just be the greatest link between what is known about the human body, and what is not and it might be the thing that helps researchers create a better life for all. http://www.articlesphere.com/Article/Adult-Stem-Cells-Rebuild--Renew-and-Rejuvenate/166030 Thu, 06 Nov 2008 00:00:00 -0800 http://www.articlesphere.com/Article/Adult-Stem-Cells-Rebuild--Renew-and-Rejuvenate/166030 Human cloning is the creation of a genetically identical copy of a human being, human cell, or human tissue. The term is generally used to refer to artificial human cloning, although human clones in the form of identical twins are commonplace, with their cloning part of the natural process of reproduction. http://www.articlesphere.com/Article/A-spiritual-perspective-on-Human-Cloning/164724 Fri, 24 Oct 2008 00:00:00 -0700 http://www.articlesphere.com/Article/A-spiritual-perspective-on-Human-Cloning/164724 India joined the international space race October 22, launching its first unmanned mission to the moon. The unmanned lunar orbiter is called Chandrayaan-1, which means moon craft in ancient Sanskrit. Scientists clapped and cheered as Chandrayaan ascended from the Sriharikota space center in southern India. Indian Space Research Organization chairman G. Madhavan Nair said the purpose of the mission is to unravel the mystery of the moon. http://www.articlesphere.com/Article/India-s-First-Unmanned-Moon-Mission/164567 Thu, 23 Oct 2008 00:00:00 -0700 http://www.articlesphere.com/Article/India-s-First-Unmanned-Moon-Mission/164567 In the realm of mortals, life may seem to be closing in on black and white. We lead our lives with the orientation that only the quantifiable, observable and overt are deemed to be true. However, in the realm of the endless, human beings are mere mortal creatures and truth is not a matter of great importance. It is a world where scary creatures lurk, ghosts and mummies cause mayhem, and humans are at the mercy of unfathomable paranormal events. http://www.articlesphere.com/Article/Scary-Creatures-in-Reality-and-Wild-Imaginings/163001 Wed, 08 Oct 2008 00:00:00 -0700 http://www.articlesphere.com/Article/Scary-Creatures-in-Reality-and-Wild-Imaginings/163001 When I was growing up everybody had a TV with maybe 5 or 6 channels. There wasn't anything known as cable TV. At my house we got channels 4, 6, 10, 12 and 18. Later on we also got channel 17 which was Fox TV. I can remember when I first heard about HBO which was a box that only got you HBO and nothing else. That privelage would cost a household maybe $50. http://www.articlesphere.com/Article/Out-With-The-Old--In-With-The-New/162234 Mon, 01 Sep 2008 00:00:00 -0700 http://www.articlesphere.com/Article/Out-With-The-Old--In-With-The-New/162234 This article teaches kids about the Crystal Farming and gives a handful of totally fun activities to experiment with for their homeschool science learning (including rock candy and homemade geodes). Its also good for boy scouts working on a badge, or for any kids that love science experiments. These experiments are part of a homeschool science program that I teach, and I promise your kids will love it. http://www.articlesphere.com/Article/Easy-Crystal-Experiments-You-Can-Share-With-Your-Kids/161772 Thu, 28 Aug 2008 00:00:00 -0700 http://www.articlesphere.com/Article/Easy-Crystal-Experiments-You-Can-Share-With-Your-Kids/161772 This article teaches kids about chemistry and is an excellent introduction to the totally fun activities in homeschool chemistry (including exothermic reactions, phase shifts, and acid indicators).

Making use of wind to power our lives is one way that we, and our governments, can help to reduce the stress on an already battered environment, and also help the economy while we're at it. http://www.articlesphere.com/Article/Some-Benefits-Of-Using-Wind-Energy/160321 Mon, 18 Aug 2008 00:00:00 -0700 http://www.articlesphere.com/Article/Some-Benefits-Of-Using-Wind-Energy/160321 The metric system has taken over the world. Meters, grams, liters, etc., are everywhere; the number of countries that don't use the metric system can be counted on the fingers of single hand. Now that it is so firmly established, it would seem appropriate to update it by adding a few more important measurements that still rely on cumbersome, old-fashioned non-metric units - the hours of the day and the degrees of a circle. http://www.articlesphere.com/Article/Isn-t-It-Time-For-The-Metric-System-To-Stop-Going-Around-In-Circles-/158544 Tue, 05 Aug 2008 00:00:00 -0700 http://www.articlesphere.com/Article/Isn-t-It-Time-For-The-Metric-System-To-Stop-Going-Around-In-Circles-/158544 The world's weather can have an enormous impact on a local scale. From a whirlwind to a cyclone, or an ice storm to a drought, the weather takes its toll. But did you know that the whole world's weather is capable of making the whole Earth move? As it rotates, the Earth wobbles as it spins on its axis. And as it slows down, the planet develops a host of different wobbles, ranging in time period from a few minutes to billions of years. http://www.articlesphere.com/Article/Our-Wobbling-Earth--Wobbled-by-The-World-s-Weather/156772 Thu, 24 Jul 2008 00:00:00 -0700 http://www.articlesphere.com/Article/Our-Wobbling-Earth--Wobbled-by-The-World-s-Weather/156772 On a summer day in Paris in 1783, Jaques Charles did something as tonishing. He roared 3,000 feet above ground in a balloon of rubber-coated silk bag filled with lighter-than-air hydrogen gas. Though this event had no significance for the next two centuries, yet Charles had launched a quest to harness the power of hydrogen for transportation. http://www.articlesphere.com/Article/Hydrogen-The-Future-Energy-Sources-For-Fuel/156347 Tue, 22 Jul 2008 00:00:00 -0700 http://www.articlesphere.com/Article/Hydrogen-The-Future-Energy-Sources-For-Fuel/156347 Research continues on the agricultural and environmental mystery known as Colony Collapse Disorder (CCD). However, finding a cause and a subsequent cure for the problem is fast becoming a race against time for scientists. The number of disappearing honey bees in recent years is indeed staggering. Many beekeepers estimate that, at the current rate of bee loss, there now may be only a ten year window to find a cure. Colony Collapse Disorder is unique since it leaves bee hives with a queen bee, a few newly-hatched adults, and plenty of food, while all of the worker bees responsible for pollination just disappear. http://www.articlesphere.com/Article/Solving-The-Mystery-Of-The-Disappearing-Honey-Bee/154840 Sun, 13 Jul 2008 00:00:00 -0700 http://www.articlesphere.com/Article/Solving-The-Mystery-Of-The-Disappearing-Honey-Bee/154840
