An overview about the chemical element Zinc
By: Joe Barrette
Zinc is a very important element. It is needed by the human body at a steady rate for proper taste, smell, and growth. It is also a very important element for pregnant mothers, to have a healthy baby, and in young children. Most foods with...
The chemistry of firework colors
By: Abby Deweese
Fireworks, like potato chips and many other things we enjoy today, are legend to have been originally created by accident. The legend starts in China with a cook who was working in a test kitchen. He mixed charcoal, sulphur and saltpeper. The mixture burned and...
How to color fire
By: Abby Deweese
Behind the beautiful color of the flames, there is a complex chemical process behind it. The process involves the Bohr theory and jumping electrons. The process and explanation are as followed:The Bohr theory of the atom says that electrons occupy only one energy level at...
Iron Rust: What is it
By: Vadim Osadchi
Rust is simply a series of iron oxides formed in the reaction of iron and oxygen with the presence of water or air moisture mixed in. Another term for rusting is corrosion'. Join iron with water and oxygen and, given enough time, it'll turn wholly...

I have a friend whose house is, reportedly, haunted. Some people will agree. She has stories of the usual sort: TVs turning on of their own accord, hearing doors slam when the house is empty, hearing faint voices. She talks of cold spots. Bad feelings...
Explaining osmosis
By: Joe Barrette
Osmosis takes place by the diffusion of water molecules through a plasma membrane. The membrane controls the flow of objects moving through it, and most polar molecules such as sugars and proteins cannot move through the plasma membrane, even though water molecules are polar, they...
