Earth Science A place for my students to get some help in Earth Science

Friday, September 15, 2006   Unreviewed as of today Graph resources http://nces.ed.gov/nceskids/Graphing/ another http://www.mste.uiuc.edu/courses/ci330ms/youtsey/intro.html See if this helps Remember that we use line graphs almost exclusively unless otherwise requested. Sylvester RN posted by James | 7:34 AM   Assignment to follow handout on graphing Most of the graph practice went well. The graphing reference in your text is pages 32-34. Read that and do page 38 group a number 4 a-d. Do group B also number 2. I will gather more data also. This is an essential skill. I will get your work during the week. I will gather all I assign you systematically whe I return Please assess you familiarity with graphs because ALL tests will have them so to not understand them hurts you. I will do a quick search to see if there are good instructions for graphs. Somethings to consider Where does the x an y axis get placed? What type scale should I use? What is the difference between inverse and direct relationships? How do independent and dependent variables differ? OK, save your questions or send them to me. Ask your fellow students and math teachers. Don't forget UFT NYC dial a teacher program also. Off to court posted by James | 7:26 AM Wednesday, September 13, 2006   Hey, I am off to court, and I wanted to make sure that I gave you some focus on what you should be doing. I would ask you to practice the questions at the end of chapters 1 and 2. Group a and b. I will get a copy of your book by Friday and give you the exact ones you need. please remember to use the chapter summary at the end or if it is a large chapter, it may be in sections and have summaries through out. Use the charts etc for help also, for that is an important skill. I will include some websites here that you can go to, and I will be sending worksheets here also. So, this week you should be familiarizing yourself with density, shape of the Earth, and look at the graph and scientific method. Basic notes you can search at wikipedia and google, but stay focused on topic and the aims I let. Any questions, write me at odontocete917@yahoo.com Identify yourself as a student in subject line. If there are new students or any need books, please ask Mr Lall or any of the scienec teachers and remember to get their names and thank them for helping my students. I will do so later. OK, Sylvester out.... www.geoteach.com www.sylvesterlinks.blogspot.com posted by James | 7:14 AM Monday, September 11, 2006   Jury dut will be until 10/06/2006 Aims for this week will include How is density measured? How can we determine the shape of the Earth? How can we graph change? How can we use latitude and longitude to determine points on Earth? How is time related to longitude? I will check wikipedia and about.com for info. Please do the same. Check here frequently and remember to go to lab and put labs in my mailbox in main office or in the science office. Please put you name and period number that I have you for Earth Science 1, 7, or 8. Thank you for your patience. Please print and take a copy to show students in class. Thnx, Sylvester Any questions, write me. JGS 917 216 0928 odontocete917@yahoo.com Notes Density From Wikipedia, the free encyclopedia Jump to: navigation, search For other senses of "density", see density (disambiguation). Density (symbol: ? - Greek: rho) is a measure of mass per unit of volume. The higher an object's density, the higher its mass per volume. The average density of an object equals its total mass divided by its total volume. A denser object (such as iron) will have less volume than an equal mass of some less dense substance (such as water). The SI unit of density is the kilogram per cubic metre (kg/m3) where ? is the object's density (measured in kilograms per cubic metre) m is the object's total mass (measured in kilograms) V is the object's total volume (measured in cubic metres) Geographic coordinate system From Wikipedia, the free encyclopedia (Redirected from Latitude and longitude) Jump to: navigation, search Map of Earth showing lines of latitude (horizontally) and longitude (vertically), Eckert VI projection; large version (pdf, 1.8MB) A geographic coordinate system expresses every location on Earth by two of the three coordinates of a spherical coordinate system which is aligned with the spin axis of Earth. Borrowing from theories of ancient Babylonians, later expanded by the famous Greek thinker and geographer Ptolemy, a full circle is assigned 360 degrees (360°). latitude (Lat.) is the angle between any point and the equator. Lines of constant latitude are called parallels. They trace circles on the surface of Earth, but the only parallel that is a great circle is the equator (latitude=0 degrees), with each pole being 90 degrees (north pole 90° N; south pole 90° S). longitude (Long.) is the angle east or west of an arbitrary point on Earth: The Royal Observatory, Greenwich (UK) is the international zero-longitude point (longitude=0 degrees). The anti-meridian of Greenwich is both 180°W and 180°E. Lines of constant longitude are called meridians. The meridian passing through Greenwich is the Prime Meridian. Unlike parallels, all meridians are halves of great circles, and meridians are not parallel: they intersect at the north and south poles. By combining these two angles, the horizontal position of any location on Earth can be specified. For example, Baltimore, Maryland (in the USA) has a latitude of 39.3° North, and a longitude of 76.6° West (39.3° N 76.6° W). So, a vector drawn from the center of Earth to a point 39.3° north of the equator and 76.6° west of Greenwich will pass through Baltimore. Time Zones and Longitude Time zone From Wikipedia, the free encyclopedia (Redirected from Time zones) Jump to: navigation, search "Timezone" and "TimeZone" redirect here. For other uses, see Time zone (disambiguation). A time zone is a region of the Earth that has adopted the same standard time, usually referred to as the local time. Most adjacent time zones are exactly one hour apart, and by convention compute their local time as an offset from Greenwich Mean Time (see also UTC). Standard Time Zones of the World Standard time zones can be defined by geometrically subdividing the Earth's spheroid into 24 lunes (wedge-shaped sections), bordered by meridians each 15° of longitude apart. The local time in neighbouring zones is then exactly one hour different. However, political and geographical practicalities can result in irregularly-shaped zones that follow political boundaries or that change their time seasonally (as with daylight saving time), as well as being subject to occasional redefinition as political conditions change. posted by James | 8:20 PM		archives links link link link
