planet and shoot them off into outer space. The place for my planet is in the Triangulum Galaxy. The Triangulum Galaxy is a spiral galaxy about 2.7 million light years (25761569076837520000km)away from Earth. The solar mass of the Triangulum Galaxy is 50 billion Mʘ (standard unit of mass in Astronomy). This galaxy has about 40 billion stars which is 1/5th of how many there are in the Milky Way Galaxy. And 1/25th 's of the Andromeda Galaxy. The name of my planet is Frigusodayin (Cold Air)(Latin, Armenian)

World War II was and most likely will be the largest and most great war to ever appear on this earth. Although it brought so much death and destruction with a striking total of over 60 million deaths, it is also the deadliest conflict to ever have happened as well. Out of all the horror that was WWII it did create a lot of advancements like the boost in advancements in technology. As well there were great social changes in the United States. Also there were significant boosts in medical sciences

Molarity – the concentration of a solution expressed in moles of solute per liter of solution 4) Molecular weight – the weight of one molecule of a molecular compound. 5) Daltons – a unit of mass identical to 1 atomic mass unit 6) Isotopes/ radioisotopes – atoms of an element containing different number of neutrons 7) Atomic number – the number of protons in the nucleus of an atom 8) pH = -log (H+) a. acid – proton donor b. base – proton acceptor c. weak acids/bases – do not completely dissociate in

INTRODUCTION Radiation, flow of atomic and subatomic particles and of waves, such as those that characterize heat rays, light rays, and X rays. All matter is constantly bombarded with radiation of both types from cosmic and terrestrial sources. This article delineates the properties and behaviour of radiation and the matter with which it interacts and describes how energy is transferred from radiation to its surroundings. Considerable attention is devoted to the consequences of such an energy

1) Demonstrate understanding of the terms atom and molecule. Atom= Smallest Unit of Matter Molecule= 2 or more atoms chemically bonded. 2) Describe paper chromatography. 3) Interpret simple chromatograms. A method used to separate a Solution, using a Paper and a beaker of water. The Substances in the Paper go up depending on their Mass. We can say that a Solution has the same substance as another solution because they form a line of the same height. 4) Describe methods of separation

those clocks on phones are controlled by the atomic clock administered by the National Institute Standards and Technology, NIST. Before mechanical clocks were invented, using “celestial bodies and sundials” were the accepted forms of timekeeping (Catwright). After the suggestion of a possible creation of a clock by physicist Isidor Rabi using his “resonance method for recording the magnetic properties of atomic nuclei” in 1945, NIST creates the first atomic clock based on Rabi’s method with ammonia

Uncle Tungsten Summer Reading Assignment General Overview Uncle Tungsten is Oliver Sacks’s description of his early life filled with the logic, excitement, and anomalies of chemistry. In the beginning, Oliver Sacks is fascinated with metals and their properties, largely influenced by his Uncle Dave, who is better known as Uncle Tungsten. He asks Uncle Tungsten, his parents, and many others, questions about anything that intrigues him typically with chemistry in mind. Throughout his boyhood, he

Personal: Albert Einstein was born March 14, 1849, Ulm, Germany. Einstein had one sister her name was Maja Einstein. Albert and his sister were close in age. Albert was born in 1879 and Maja was born in 1881. He was raised and from a Jewish family. Albert Einstein’s parents’ names were Hermann Einstein and Pauline Einstein.

A cell is defined as the smallest and most basic 8nit of life-microscopic, self-contained units enclosed by a water repelling membrane. The human body is composed of approximately 100 trillion cells. We also learned that a genome is the complete set of genes of an organism, or also known as genetic information. We learn that a gene is a segment
