Many battery choices are available today for almost all applications. But the choices between wet cell and dry cell are limited. In most cases, portable devices do not have this option. The most...

With origins in China to its ability to revolutionize production processes, recycling is more than just a categorization and collection of paper, bags, cans and bottles.

The world around us can be a fascinating place. A whole new level of complexity can be added to the fascination by adding magnification. A simple magnifying lens composed of a piece of ground...

Many schools require students to complete one science project each year to be displayed at the science fair. These science projects don't have to be complicated to win awards. Sometimes the best...

You see glass everywhere in modern life, from windows in buildings and cars to dishes on your table. Glass acts as the screen in many computer monitors and televisions. Artists even form glass...

Recycling has become second nature to many people, and many municipalities across the country either provide curb-side pickup service or operate drop-off recycling centers. With all this material...

The glass needs to be cleaned of all debris or smudges before the backing is applied. This keeps the coating from looking distorted or from having places that it didn't cover the glass. The metal...

A magnifying glass is used most often to optically enlarge letters, numbers, words or objects. One must admit, it's somewhat fun to magnify stuff. In this simple experiment we will bend light...

Used most often for prescription eyeglasses, color changing or "photochromic" glass goes from clear to darkly tinted when exposed to ultraviolet (UV) radiation. This allows the wearer to protect...

Learning science is a great reason to experiment with various items around your house. Squeezing a small egg through the opening of a glass milk bottle is a neat experiment because an egg cannot...

Experimenting is an exciting tool of science. You are able to make hot ice with just a few ingredients. One of the ingredients consists of sodium acetate which is found in most hand warmers.

The graduated cylinder is a tall, thin container used to measure the volume of liquids. It is a very common piece of laboratory equipment. Chemists use graduated cylinders just as you would use...

Crystal glasses can be used to make sounds in at least two different ways. One is by lightly "pinging" the sides of the glasses, and a second way is by rubbing the glasses' rims. Both methods work...

Children of all ages will be amazed and delighted by the results of this simple experiment to make your own rainbow. In addition, you will be teaching a memorable lesson on refraction, how light...

Certain physical laws make it possible to light a fire using a magnifying glass or other lens.

There's a real science to fusing fun with learning when it comes to entertaining the kids, and it's a crafty Mom who can blend the two seamlessly. But it doesn't take a rocket scientist to teach...

Creating neon signs is mainly done by hand, due to the fragility of the glass work. The signs are made of thin glass tubes that are bent into desired shapes. This is usually letters. The tubes...

The formula to calculate density is the mass of an object divided by the volume, expressed as mass per unit-volume. Historically, water was used to calculate density, measuring the amount of water...

The easiest method of removing salt from salt water is a process called distillation. The water is heated, turned to a gas, condensed and collected in a purified form. The salt will be left...

A barometer is a scientific instrument that is commonly utilized to measure the level of atmospheric pressure in an area. A Fortin barometer is one of the most popular types of barometers. It is...

A pH meter is used to measure the pH (acidity or alkalinity) of an aqueous solution. A pH meter consists of a probe and a voltmeter. The most common commercially available pH probes consist of a...

Glass slides are clear rectangles of glass that are usually mounted on the viewing stage of a microscope. Introduced sometime during the nineteenth century, the 3 by 1 inch glass rectangles and...

Fiberglass is a term heard quite often to refer to a common material used in a number of real-world applications, but how many people actually know what fiberglass is? It's a fairly complex...

A magnifying glass is a tool used for a wide variety of professional and amateur purposes. In its simplest form the magnifying glass is a round lens enclosed by a metal or plastic frame and...

Vacuum flasks are used to separate liquids from solids when used in conjunction with a filter in the mouth on top of the jar. Vacuum flasks typically will have a small mouth opening and will allow...

Kids love scientific experiments with actual results, and there is almost no other with such exciting results as making hydrogen-filled balloons. With a little preparation, this experiment is...

Microscopes allow you to magnify items that you would not usually see with the naked eye. They are scientific aides and assist in the investigation of small items. You can make your own portable...

A vacuum flask, also commonly known as a thermos, is a container that keeps the contents housed inside it insulated from the effects of the outside environment, therefore keeping it hotter or...

When light passes from the air into glass, it slows down, and when it leaves the glass, it speeds up again. If the light hits the glass at an angle instead of dead-on, it undergoes refraction. The...
