The Title of Planet Must be Given Back Voting done at the International Astronomical Union convention about pluto’s status of being a planet was a harsh new reality‚ with the majority voting for pluto’s demotion. Professor Alan Stern‚ chief scientist for the New Horizon mission set for learning more about pluto‚ called the outcome "an awful decision" and described the new definition as "internally inconsistent" ("Why Is Pluto No Longer a Planet?"). The debate of pluto being a planet has started

ATOMIC THEORIES AND HISTORY * Democritus (Greek) - “atomus” meaning indivicible * Indivisible particles called atoms * John Dalton – MODERN ATOMIC THEORY: 1. All matter is made of tiny‚ indestructible particles called atoms (Democritus) 2. All atoms of a given element are identical (not accepted today bc isotopes) 3. Atoms are neither created nor destroyed in chemical reactions (Lavoisier) 4. Atoms of different elements form compounds in whole number ratios (Proust)

Case Study: Does the Sun’s Angle Affect the Output Of a Solar Cell? Abstract During the experiment to determine Solar Cell Energy‚ one unit of flexible solar cells was exposed to solar radiation at different angles in one axis of rotation. The cells were attached to a adjustable plane with a protractor that acted like a “see-saw” to adjust the angle of the solar cells to the Sun. Around the plane‚ a column of cardboard was constructed with black fabric covering the inside

1) "The Antarctic is the vast source of frigidity on our planet‚ just as the sun is the source of our heat‚ and it exerts tremendous control on our climate ‚" [Jacques] Jacques Costeau told the television camera . "The cold ocean water around Antarctica period north to mix with heater water from the Torrid Zone ‚ and its upwellings help to aplomb both the open water and our atmosphere. Yet the fragility of this regulating system is now threatened by human activity‚" (Captain Jacques Yves Costeau

Our solar system consists of the sun and nine planets. Mercury is the closest planet to the sun. Mercury was named after the Roman God of Commerce and Thievery. It might have gotten its name because of the way it quickly appears and disappears from Earth’s view. Mercury is the second smallest planet in the solar system; Pluto is the only planet that is smaller. Earth’s diameter is about 7‚200‚ while tiny Mercury has less than half of that size‚ about 3‚000 miles in diameter. Mercury‚ a planet‚ is
