Expert Author: Kathy Brasch | Summary You often hear the term brix and brix refractometer when testing samples for sugar content. Just what is a refractometer? A refractometer is an instrument that measures the refraction of light through a substance. The refractive index becomes higher in a substance of higher concentration. A refractometer has a wide variety of uses such as measuring sugar concentrations and liquid concentrations. Refractometers are sometimes called "Sugar concentration meters" or "Density meters" depending on the application. Expert Author: Kathy Brasch | Summary Remember back to your school days when you first saw amoeba swimming around in pond water? You thrilled to seeing the microscopic organisms moving around, bumping into each other. Now you want to share that memory with your children or grandchildren as they grow. But you don't want to spend their college money on a new high-priced microscope, so what can you do? No problem - you can now find many microscopes that are either used or demo models at a much more reasonable price. But first you need to determine what type of a used microscope you want: compound or stereo/dissecting. Expert Author: Joe Kanooga | Summary Various electronic kits are available, and the potential benefits go beyond the finished product. For a start, it's a hands-on opportunity to become familiar with some terminology. By high school, science classes often include an introduction to electronics concepts, including circuit diagrams, resistors, and diodes. Expert Author: Joe Kanooga | Summary So you have a beautiful brand new science kit, such as a chemistry set, and you want to set up a truly scientific experiment, something really professional, something tightly organized and keenly observed. Sounds like a great idea so far! So where do you begin? The first step, perhaps the most important step, is a well-thought-out hypothesis. This article provides instructions for how to make a great hypothesis. Expert Author: Joe Kanooga | Summary Kids electronic kits are a great way to learn how different energies, from solar to hydrogen, work together. These energies are used to develop new technologies and better ways of doing things. Using electronics kits to harness these forces is not only a great way to learn but can also be a lot of fun. Expert Author: Joe Kanooga | Summary To get really good science fair projects from pre-packaged kits takes some creativity, but it can be done. Though many kids science kits are designed with specific experiments in mind and may even come with detailed instructions, it's probably best to approach the kit as a set of tools that will help you in your own unique research. Expert Author: Joe Kanooga | Summary It is surprisingly easy and enjoyable for a student to create a science fair project that uses electricity. This article offers five ideas for great science fair projects using readily available electronic kits, such as Elenco Electronic Project Lab and Thames and Kosmos. Expert Author: Joe Kanooga | Summary Blast off to learning success! Educators are recognizing numerous exciting benefits to using model rocketry in the curriculum. It's an economical resource, with quality model rocket kits available from many manufacturers ranging from Estes model rocket kits to Aerotech, LOC and Edmonds models. Expert Author: Joe Kanooga | Summary Using the scientific method and good science kits can help you succeed with any science fair project. It can make the difference between failure and success. So to help you get started, we've compiled the following list of a few crucial steps. Expert Author: Joe Kanooga | Summary Chemistry sets from brands like Thames Kosmos, Scientific Explorer and Powertech provide children with hours of educational entertainment. The great thing about these sets is they provide all the chemicals and materials required to conduct the experiments. But what do you do when the chemicals have all been used? 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. 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. Expert Author: Amarendra Singh | Summary 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. Expert Author: Ellen Bell | Summary 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. Expert Author: Lee D Harris | Summary 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. Expert Author: William J. Lund | Summary There is always something new happening in the world of science. In fact, there are so many new scientific discoveries and inventions, that it’s virtually impossible to stay abreast of all the new information. Here are a few really cool new inventions that are under development. Expert Author: Debra L. Morrison | Summary 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. Expert Author: Dave M Hill | Summary 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. Expert Author: Darlene Gremlek | Summary 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! Expert Author: Ellen Bell | Summary 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.
