Earth's Magnetic Field

-
Earth is the largest magnet known to man. It stretches from the core of our planet, to outer space, known as the magnetosphere.  The magnetic field is caused by Earth's inner core. It is caused by electric currents caused by the melting and convection currents inside Earth's iron core. What many people don't know is that the Earth's magnetic field is on a 11 degree tilt. Although this may not seem too strange, it has many affects on magnetism.

The geographical north and south poles are located in the places they should be, but the actual magnetic poles are pretty much flipped. The north magnetic pole is located near the south geographical pole, and vise-versa. Additionally, the magnetic poles, but at an extremely slow speed. After several hundred of thousands of years, they will be flipped again.

Earth's magnetic field also plays a huge role in keeping us safe. The magnetic pole helps to deflect and block solar wind and cosmic rays from entering our atmosphere and destroying layers,  such as the ozone layer. If the ozone layer was destroyed, ultraviolet rays from the sun, and space, would easily enter and burn and destroy everything.

In the future, we can attempt to learn even more about our magnetic field. This can help to let us find out how it is vital to our survival, and why we need to preserve it, and make sure it stays intact. Additionally, we can learn a lot from our magnetic field and use it for experiments and tests about magnetism.

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 ...

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 ...

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...
