 Earth is surrounded with amazing materials form gold we wear as jewelry to the oil that powers our cars. Chemicals are the building blocks from which all the material inside Earth are made. There are a lot of different types of elements and a lot of them are metals. Most metals around the world are not actually metals at all but they are alloys. Alloys are metals combined with other substances in order to make them better in some way.  The best way to think of alloys is as a material that is made up of at least two different chemicals.  
People sometimes might think of an alloy mixture is confusing. So, how are alloys made? The traditional way of making alloys was to heat and melt the components to make liquids, mix them together, and then allowing them to cool into what’s called a solid solution. A solid solution is the solid equivalent of a solution like salt in water. The alternative way to make an alloy is to turn the components into powder, mix them together, and then fuse them to high pressure and high temperature. This technique is called powder metallurgy. A third method of making alloys is to fire beams of ions, which are atoms with too few or too many electrons into the surface layer of a piece of metal. This technique is known as a precise way to make alloys. 
There are 4 mainly different types of alloys. Brass is one of the most common alloys. Brass is an alloy of copper and zinc, brass is mostly used in door locks and bolts, brass musical instruments, central heating pipes. The other type alloy is bronze. Bronze is an alloy of copper and tin. Bronze is mostly found in decorative statues, musical instruments. Steel is another important type of alloy. Steel is an alloy of carbon and iron, which means it is very strong and hard. It is the most used alloy, used in construction, appliances and cars. The last type of alloy is sterling silver. Sterling silver is an alloy of silver and copper, it looks like silver, but it is much stronger. It mostly used to make jewelry, dishes, utensils, and medical equipment. 
Some types of alloys are very strong metals, so in the future they will be very help full. The future for alloys is very bright, we can use them for a lot of important things. Alloys in the future would be very helpful for natural disasters, if people used most alloys to build their house structures, they can stand stronger during natural disasters. In the future people can change the alloy is made and make it stronger. Alloy is important because the combination of elements results in a substance that has better characteristics than the characteristic of the individual elements alone.

Chemically termolecular reactions: The fourth class of chemical reactions

Chemically termolecular reactions: The fourth class of chemical reactions Maisy Chase Up until now only three classes of chemical reactions were known. Unimolecular reactions occur when one reactant undergoes bond breaking or forming to create different products. Bimolecular reactions are where two reactants collide and then undergo bond breaking or forming. Termolecular association reactions, where two reactants collide to form a whole with a new chemical bond between the two reactants. A third molecule, known as the bath gas, then removes some of the internal kinetic energy of that molecule to stabilize it. Researchers from Columbia University , led by Assistant Professor of Mechanical Engineering Michael P. Burke, have discovered a fourth class of chemical reaction known as “chemically termolecular reactions.” This involves the breaking and bonding of three molecules. The team showed that these chemically termolecular reactions not only are major chemical pathways but also ...

Molecular Gastronomy   By: Shahminah Mahar-ullah Date:3/22/19 Molecular Gastronomy is both a fusion of science and cooking. The scientific discipline gives the chef complete control of what the texture, taste, and physical appearance of the dish. Molecular Gastronomy is a modern unique style of cooking that some would say it could be considered art. There are three aspects of Molecular Gastronomy, as i said before it is texture,taste,and physical appearance. Molecular Gastronomy can have a very simple and familiar taste or a new and unique taste. Taste is often a aspect that is forgotten about in Molecular Gastronomy. Mostly because people who don't know much about the style of cooking kinda forget that its actually cooking ,not just some form a science. Taste is the main focus with cooking in general and with molecular cooking taste can be brought to a whole new level since you have complete control over each part of the dish. Same goes for physical appearance and ...

Force and Motion

Zach Fluck Science blog Force and Motion Blog Sir Isaac Newton was an English astronomer, physicist, and mathematician, born on December 25, 1642. He died on March 20, 1727, most likely from mercury poisoning or old age. However, during his life, he made several contributions to modern science and advanced our understanding of physics tremendously. Arguably his most famous discovery was gravity. However, he had to use his 3 laws of motion to make this accomplishment. Newton understood that an object at rest will stay at rest, unless acted on by unbalanced forces. Therefore, if an object such as an apple is in a resting position there must be a force to make the apple fall to the ground. He discovered this invisible force to be gravity. At a young age Newton was removed from school to be a farmhand. Despite returning to school the turning point in his live was he left his hometown to attend Cambridge University. After attending Cambridge he returned to his hometown where his observat...
