Running head: CLASSROOM ARRANGEMENT Classroom Arrangement and Rationale EDU 320/Classroom Management Classroom Arrangement and Rationale Classroom arrangement is the first step to a successful learning environment and the first step to successful classroom management. Once the classroom arrangement is configured‚ other areas of the classroom can be more easily organized. Classroom arrangement can make or break a teacher’s ability to manage the classroom properly and should support the educator’s

If we go back to the history of 1945‚ we come to know the history of 1945; we come to know the worst type of nuclear disaster the world had witnessed. On August 6‚ 1945 an atom bomb was dropped on HIROSHIMA in Japan‚ which devastated the entire town killing 66‚000 people and injuring nearly 69‚000. On August 9‚ 1945 another atom bomb was dropped on NAGASAKI. This bomb killed nearly 39‚000 people and injured more than 25‚000. Nuclear weapons are thus‚ far more destructive and harmful to the society

Properties of Water Introduction: Water’s chemical description is H2O. As the diagram to the left shows‚ that is one atom of oxygen bound to two atoms of hydrogen. The hydrogen atoms are "attached" to one side of the oxygen atom‚ resulting in a water molecule having a positive charge on the side where the hydrogen atoms are and a negative charge on the other side‚ where the oxygen atom is. This uneven distribution of charge is called polarity. Since opposite electrical charges attract‚ water

while others have to buy water or walk for miles to attain enough water to survive. In many cases water is being wasted. Hydrogen bonding holds water molecules together. At 32 degrees the kinetic energy is so low that the water freezes. When the temperature rises the kinetic energy thaws and we then have liquid water again. When the molecules absorb energy from the sunlight evaporation takes place and this is called water vapor which is

Chemical bond From Wikipedia‚ the free encyclopedia Jump to: navigation‚ search A chemical bond is an attraction between atoms that allows the formation of chemical substances that contain two or more atoms. The bond is caused by the electrostatic force of attraction between opposite charges‚ either between electrons and nuclei‚ or as the result of a dipole attraction. The strength of chemical bonds varies considerably; there are "strong bonds" such as covalent or ionic bonds and "weak bonds"

terrifying powerful explosive‚ as devastating as any other of the deadly explosive weapons of modern war. Had the war continued until the projected invasion on November 1‚ additional fire raids of B‑20’s would have been more destructive of life and property than the very limited number of atomic raids which we could have done in the same period. But the atomic bomb was more than a weapon of terrible destruction; it was a psychological weapon as well. The bomb served exactly the purpose we intended.

Chemicals of Life • With the exception of water‚ virtually all chemicals of life are CARBON based • Molecules that contain Carbon are considered organic with some exceptions such as CO2 • Carbon has 4 valence electrons so it is oriented in a tetrahedron shape Sketch→ • Carbon can form up to 4 covalent bonds and can form long chains‚ rings‚ and branched chain molecules • Carbon acts as the backbone of biological molecules • Molecules that only contain carbon and hydrogen are known as hydrocarbons→

Physical properties can be seen‚ touched‚ or even measured without the identity of the substance changing. The identity of the substance can be its shape or color. Three physical forms of a substance are solid‚ liquid‚ and gas. Water for example can transform into all three physical forms without its identity changing. The characteristic of water as a shape can be used as an example of a physical property. Water can be frozen into ice‚ vaporized‚ or liquidized. The shape of water as a solid is
