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.
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.
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.
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.
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.
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.
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.
