Biology Honors 2. American Sign Language (ASL) 3. Physical Education (P. E. ) 4. ASB 5. English Honors 6. Geometry Honors Activities Redlands High school has a various amount of clubs, sports and activities. I am in involved in a few clubs and a couple of activities. I am the secretary for the freshmen class ASB, I am in Key Club, and I am also part of the ASL club. These clubs are very important to me and I dedicate my time and hard work to them as much as I can. ASB stands for the Associated Student Body. Students in ASB plan, organize, and participate in such activities as formal and informal dances, Homecoming, Spirit Week, grade-level competitions, community awareness projects, cultural events, and Staff Recognition throughout the year. The students in ASB work to raise school spirit in events held during lunch and during any other events. They are always on top of everything and ahead on every task. I am the secretary and my Job is to keep minutes, which report member attendance of all meetings. I keep general files stocked and make additions to the general files. Informing the presidents and vice- opportunity for me and I enjoy it a lot. Key Club is the oldest and largest service program for high school students. It is a student-led organization whose goal is to teach leadership through helping. Key Club International is a part of the Kiwanis International family of service-leadership programs. A local Kiwanis club sponsors many local Key Clubs. This club includes students who want to dedicate their time to community service and other school activities. We raise money and try to make our club better so we have more opportunities to go out and compete with other schools. We all have fun and work hard at the same time. It is a great use of my time and effort. American Sign Language Club (ASL) is a club where all of the ASL class students get together and go above and beyond what is taught in class. We learn different types of signs and also put up a lot of fundraisers for our club so we can afford to have professional deaf speakers come and meet us. We try to organize fun sport days for the students that involving signing as an educational purpose. We work hard to make our ASL classes go up. Personal Statement I plan on doing a lot throughout high school and reaching all of the goals I have set for myself. During my four years of high school I want to take as many AP and honors lasses as possible and receive good grades in them. I want to earn scholarships so I can get into a nice medical school. School is very important to me and I feel like I must complete as many classes as I can throughout the summer so I can have room for my core classes during the school year. Last year over summer I took a semester of health class. I took that class because I wanted to take P. E, ASL, and ASB in my freshmen year. I did not have room for health and felt like taking it over summer would be a great idea. This year I want to take P. E. both semesters of summer school so I can have room for the classes I really need to take. I always work hard when it comes to school and make sure I pass the class. I will take full advantage of this scholarship and will not let it go to waste at all. My future career goal is set and ready. I have always wanted to be a Pediatrician. Working with babies, kids, and teens is something I know I will enjoy. In order for me to reach my career goal, I have to finish my schooling along with good grades. I need to get accepted to a good college and take all the classes necessary for my Job. I have everything planned and set up and I am glad that AAA Academy is there for the students who need to take extra

Tungsten or Wolfram - Chemical Physical Properties

Tungsten or Wolfram - Chemical Physical Properties Tungsten is a grayish-white transition metal with atomic number 74 and element symbol W. The symbol comes from another name for the element- wolfram. While the name tungsten is approved by the IUPAC and is used in Nordic countries and those speaking English or French, most European countries use the name wolfram. Here is a collection of tungsten or wolfram facts, including the elements properties, uses, and sources. Tungsten or Wolfram  Basic Facts Tungsten Atomic Number: 74 Tungsten Symbol: W Tungsten Atomic Weight: 183.85 Tungsten Discovery: Juan Jose and Fausto dElhuyar purified tungsten in 1783 (Spain), although Peter Woulfe examined the mineral which came to be known as wolframite and determined that it contained a new substance. Tungsten Electron Configuration: [Xe] 6s2 4f14 5d4 Word Origin: Swedish tung sten, heavy stone or wolf rahm and spumi lupi, because the ore wolframite interfered with tin smelting and was believed to devour the tin. Tungsten Isotopes: Natural tungsten consist of five stable isotopes. Twelve unstable isotopes are known. Tungsten Properties: Tungsten has a melting point of 3410/-20 °C, boiling point of 5660 °C, specific gravity of 19.3 (20 °C), with a valence of 2, 3, 4, 5, or 6. Tungsten is a steel-gray to tin-white metal. Impure tungsten metal is quite brittle, although pure tungsten can be cut with a saw, spun, drawn, forged, and extruded. Tungsten has the highest melting point and the lowest vapor pressure of the metals. At temperatures exceeding 1650 °C, it has the highest tensile strength. Tungsten oxidizes in air at elevated temperatures, although it generally has excellent corrosion resistance and is minimally attacked by most acids. Tungsten Uses: The thermal expansion of tungsten is similar to that of borosilicate glass, so the metal is used for glass/metal seals. Tungsten and its alloys are used to make filaments for electric lamps and television tubes, as electrical contacts, x-ray targets, heating elements, for metal evaporation components, and for numerous other high temperature applications. Hastelloy, Stellite, high-speed tool steel, and numerous other alloys contain tungsten. Magnesium and calcium tungstenates are used in fluorescent lighting. Tungsten carbide is important in the mining, metalworking, and petroleum industries. Tungsten disulfide is used as a dry high-temperature lubricant. Tungsten bronze and other tungsten compounds are used in paints. Tungsten Sources: Tungsten occurs in wolframite, (Fe, Mn)WO4, scheelite, CaWO4, ferberite, FeWO4, and huebnerite, MnWO4. Tungsten is produced commercially by reducing tungsten oxide with carbon or hydrogen. Biological Role: Tungsten is the heaviest element with known biological functionality. No use in humans or other eukaryotes is known, but the element is used by bacteria and archaea in enzymes, principally as a catalyst. It functions in much the same ways as the element molybdenum does in other organisms. When tungsten compounds are introduced to soil, they inhibit earthworm reproduction. Scientists are studying the use of tetrathiotungstates for use in biological copper chelation. Tungsten is a rare element, initially thought to be inert and only slightly toxic to humans. However, now it is known tungsten dust inhalation, skin contact, or ingestion can cause cancer and other negative health effects. Tungsten or Wolfram Physical Data Element Classification: Transition Metal Density (g/cc): 19.3 Melting Point (K): 3680 Boiling Point (K): 5930 Appearance: tough gray to white metal Atomic Radius (pm): 141 Atomic Volume (cc/mol): 9.53 Covalent Radius (pm): 130 Ionic Radius: 62 (6e) 70 (4e) Specific Heat (20 °C J/g mol): 0.133 Fusion Heat (kJ/mol): (35) Evaporation Heat (kJ/mol): 824 Debye Temperature (K): 310.00 Pauling Negativity Number: 1.7 First Ionizing Energy (kJ/mol): 769.7 Oxidation States: 6, 5, 4, 3, 2, 0 Lattice Structure: Body-Centered Cubic Lattice Constant (Ã…): 3.160 Sources Lide, David R., ed.
