Transcript: Earth revolves around the sun once per year, the axis of rotation points in the same direction throughout the yearly year. The heat and solar energy provides a lot of things for the earth. Nutation It is the rotation of the solid Earth around its own axis. The main results of Earth's rotation are day and night. Earth's path about the galaxy The earth moves around the galaxy in a circular path around the sun. Precession Barycenter The seasons in the Southern Hemisphere and Northern Hemisphere are detewrmined by the amount of sunlight they get. The sun's energy affect food webs on earth. References Solar energy essential to plants The sun produce energy which is transferred to the earth by radiation. photo credit Nasa / Goddard Space Flight Center / Reto Stöckli A rocking swaying or nodding motion in the axis of rotation. The seasons in the southern heimisphere opposite to those in the northern hemisphere. The suns energy affects the food web because if the sun was not here everything that is living would die out at some point Revolution of the earth around the sun Are non-rotating cordinates with origin at the center of mass of two or more bodies. -Wikipedia -harunyahya.com -http://calgary.rasc.ca/howfast.htm -http://www.learner.org/jnorth/tm/ReasonsBack.html -http://apollo.lsc.vsc.edu/classes/met130/notes/chapter16/precession.html -http://christophercrockett.com/astrowow/obliquity/ -http://scienceprojectideasforkids.com/2010/barycenter-of-the-earth-moon-system/ -http://scienceblogs.com/startswithabang/2012/02/29/the-physics-of-leap-day/ -http://www.abcteach.com/documents/clip-art-world-map-northern-and-southern-hemispheres-color-40128 -http://www.danbury.k12.ct.us/elemweb/aaaoldElempages/sitesweb/foodweb/indexfoodweb.html - Electronic Poster Explain the rotation of the Earth Energy is essential to plants because solar energy comes from the sun and the sun helps things grow like plants A change in the orientation of the rational axis of a rotating body.

Transcript: Why Study History? Industrialization lead to large changes in education and society. Industrialization and technology lead to urbanization which lead to development of social institutions such as charities, reform groups and governmental entities. Industrialization and urbanization lead to social division of labor, class conflict, and a need for a secondary education. (Rury,p 4-9) Cultural capitol-gaining status from knowing how to behave in certain situations Social Status -gaining status through association in a social group.. Human Capitol -- the ability of some groups to gain status through knowledge. Ideologies, such as racism and sexism, are beliefs and ideas; culture is patterns of behavior -- both affect relationship between culture and education. (rury p. 9-15) Urbanization lead to small rural schools being consolidated into larger schools. Industrialization lead to curricular differentiation. Education became an instrument to assign people to social roles. Education became a potent poltical issue. (Rury, p 17-18) In the 19th century schools were coeducational, providing boys and girls educational opportunityies. Female enrollment grew until girls outnumbered boys. Women also attended academies, high schools and colleges. These changes could have lead to first women's rights movement. After Civil War education of African Americans increased. An elite educated population could have contributed to effective challenges to racism and discrimination in 20th century. (Rury,p 19) Many people compare studying history to reading a story. One must remember that the story must be confirmed with facts gathered from the period of time being studied. New evidence will be uncovered making the ideas presented in Rury's book obsolete. Dates and names are presented not for memorizing but to help readers gain perspective.

This value is also defined by the name "Avogadro's number",named after the Italian Physicist Avogadro, who suggested that "equal volumes of gases under the same conditions contain the same number of molecules",which was useful to assertain atomic and molecular weights, whcih altogether led to the discovery of the value of a mole of any substance A mole of a substance is 6.02 x 10^23 representative particles of that sunbstance, and these represntative particles could be atoms, ions, molecules and formula units Moles Electronic Poster Azzam Yazji Chem PAP Period: 3 How was the value of a mole determined? What is a mole? How are moles used in Chemistry? Moles are used in Chemistry as a bridge between the number, mass, and volume of atoms. For example, moles can be used in conversion factors to figure out the mass of a certain compound when knowing its volume. Other than being a connector between the matter's different properties, a mole also serves as a translator, meaning that it helps quantify what happens in chemical equations on macroscopic levels. Moles relations Summary Citations A mole is a unit of measurement which means that it can be compared to properties of atoms using the appropriate conversion factors. For the number of atoms, each mole of a certain atom has 6.022×10^23 atoms of that atom. For the volume of atoms, each mole equals 22.4 liters at standard temperature (0 degrees celsius) and standard pressure (1.0 atm). For the mass of atoms, each mole of an atom has the exact atomic mass of that atom in grams, and if atoms formed compounds, a mole of that compound would be the total of their masses in grams or their molar mass How are moles related to volume, mass and number of atoms?
