In this experiment you will make something that is liquid when it's under pressure and it's close to solid when it's squeezed.
Arctic silver is a compound used to insulate ceramic parts and increase conductivity. Primarily used in the insulation of computer parts, arctic silver is not a fashion accessory but a necessity...
The science of nanotechnology has taken the concept of manufacturing to a whole new level. Nanotechnology works on the molecular level–constructing, reconstructing and manipulating...
Molecules are always in motion. It may seem strange to think of the molecules in a table or chair as moving but they are. By definition, heat is molecular motion, so if the molecules are moving...
Organic chemistry is the science of molecules that are built around carbon atoms: natural gas, petroleum, plastics, alcohols and many other industrial chemicals. This branch of science has its own...
Moles are units of measurement used in chemistry that were invented because existing measures where inadequate. When chemical reactions take place, they may not be measurable in grams, molecules...
Molecules are the smallest part of a compound that is able to express the characteristics of that compound. Molecules may contain just one atom or multiple atoms. In chemistry computations,...
When you listen to the weather reports on TV, you may get a little confused listening to all the jargon; with a little decoding, however, you can start to understand the mechanics of weather. High...
Microwaves are a form of radiation that run along the electromagnetic spectrum. This spectrum is made up of different energies including radio and light waves. It even has gamma radiation, which...
Diffusion is a term used to describe when molecules move, usually across each other. Chemistry textbook definitions say that diffusion is the way in which material moves to establish balance....
Osmosis is the diffusion of water through a plasma membrane (lipid bilayer). It is a form of active transport. The water molecules diffuse through a semi-permeable membrane, moving from areas of...
The recipe for nourishment or energy begins with sunlight and cells. All self-replicating living things, from bacteria to whales, are made up of cells. Each cell can take care of itself by...
In order to function properly and stay alive, cells must maintain homeostasis. Homeostasis is a state in which everything within the cell is in equilibrium and functioning properly. The state of...
An MRI scan, or Medical Resonance Imaging Scan, is one of the most common types of scans ordered for injuries and serious medical conditions. These scans are done for a variety of reasons,...
Hydrogen bonds are connections formed when a partially charged hydrogen atom is attracted to a negative charge on another atom. Most often these bonds form between hydrogen and negatively charged...
Salt does indeed dissolve in water. However, there is a maximum limit of concentration that salt can have. When the salt concentration reaches its maximum, the salty water has become saturated,...
Nanotechnology is a science in its infancy, with unforeseen potential in its wake. Through it, science explores the molecular world of atoms and molecules with the intention of rebuilding and...
Making sugar crystals is one of the original science projects. One of the reasons that this science project is so popular is because it is relatively easy to do and there are fast results. It is...
Soap molecules are made of long chains of hydrogen atoms and carbon. The molecules have two distinct ends, and each plays an important role in the cleaning process. One end of the soap molecule...
Substances can be classed as polar or nonpolar. Imagine you had a supply of little bar magnets the size and weight of toothpicks and a supply of actual toothpicks. If you tried mixing all these...
Some tasks build your self image as you make a home for your family. Removing soap scum is one of those tasks that, if most of us had our way, wouldn't be on the list. Whether you use a commercial...
Steel isn't just an alloy of carbon and iron, it's one of the most vital parts of the structure of our modern world. Without it our skyscrapers would topple, our automobiles would crumble and...
