Atoms in Air

-
Atoms are everywhere, in the air we breathe, the food you eat, to the water you swim in. Why are atoms in these things? By definition, atoms are “the basic unit of a chemical element”. They are so much more thought, they make up everything in our world. But is the amount of atoms in different things or places vary? For example, when climbing a mountain, why does the air become thinner, and more challenging to breath in? 21% of the air we intake is just atoms! So why does the air get thinner when you get in higher climates.
    About 21% of oxygen we breathe is atoms. The reason the air gets thinner, is because it is closer to the top of the atmosphere. As you get closer to the atmosphere there becomes less atoms, which makes less breathable air. As you know, there are very few atoms in space. So from Earth’s atmosphere, as you get higher up, there becomes less and less atoms, making it become harder and harder to breathe.
    At sea level, the altitude is much more suitable for human life forms, such as most mammals and other animals. The pressure at this altitude is about 15 pounds per square foot. As you rise into a higher altitude, the air still weighs about 15 pounds. When I first learned this, I was shocked. I thought for sure that it would weigh a ton less. After reading more I learned that it is the same amount of air, it’s just that there are less variables in the air. This includes atoms. Now we know a little bit more about these tiny atoms in our world!

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 ...

Mahar-ullah Shahminah- Molecular Gastronomy

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...
