The recipe for a great cup of coffee proportion, grind, water and freshness. Understand and follow the guidelines for each of them, and you’re on your way to brewing a great cup of coffee every time. 1. The right GRIND The shorter the brewing process, the finer the grind. Each specific brewing method has a [...]
How to make salt and sugar crystals, with science fair project ideas. Crystals have always held a particular fascination for people because a high degree of order seemingly emerges out of disorder. And since growing crystals is easy and, in many cases, inexpensive, this activity is one of the all-time classic classroom and science fair [...]
Explanations and informations on the solar system for kids. The center of the Solar System is our sun. The Sun is a star, and the largest and heaviest object in the Solar System. Everything else in the Solar System either moves around the Sun, or moves around something else that is, itself, moving around the [...]
Need a fun experiment for kids to do in science class? Have them combine baking soda and vinegar and see what happens. The ingredients in this experiment are safe and are found in most households, and when they combine, they produce a reaction that pretty dramatic. In fact, baking soda and vinegar are combined to [...]
What is the science behind the chemical elements that are synthesized and used for glow sticks? An incandescent light bulb wastes about 80% of its energy producing heat, as anyone who has touched a lighted bulb can testify to. Nature does it differently, and. Even scientists wax enthusiastic over the production of “cold luminescence” by [...]
Carbon-14 or “radiocarbon” dating can be used to judge the approximate age of potentially ancient materials. Carbon-14 dating is a process by which scientists or archaeologists might measure the ‘age’ of a piece of organic matter, or its date of death, to be more specific, by comparing the number of carbon-14 isotopes in the sample [...]
Learn about carbon-14 and its uses in dating. How is it formed and how are its measurements used to date objects? WHAT IS CARBON-14? Carbon-14 is a naturally-occurring isotope of the element carbon. Carbon, which is represented by the element symbol C, has the atomic number of 6 (determined by the number of protons its [...]
A sample’s specific gravity can be obtained through the use of a simple formula, but you may need a few hints to get your measurements. The specific gravity of a material is its density as compared to that of a given substance, usually water, by standard of volume. Another perhaps more obviously descriptive term is [...]
Converting square feet and acre measurements. Most real estate in the English-speaking world is sold and listed by the acre. This unit of measure is one that is not generally known off the top of most people’s heads, in fact, most people when asked would be hard pressed to list exactly what an acre really [...]
