Reply to this thread.The first is to reply to this thread with a role played post of your student taking the test. Based on that post, I will determine their grade for the class. This is based on the 'surprise me' idea of grading. Send Tapendra Trishna a PM.Your PM needs to follow these guidelines:Needs to have the title format of "Year / Student Name" (5th Year / Jane Doe)You need to state what grade you want your student to have.You need to explain what they have done in the class to receive that grade.If I feel it is necessary, I may question your reasoning, especially if your requested grade is sharp contrast to your student's performance in past class threads and on the board as a whole.

The three-and-a-half month marathon was almost over. Of course, there was still more to come but, for now, Sasha was looking forward to being finished with the first step. He was exhausted - mentally, physically and emotionally. He was ready for classes to be done for the term. There were some exams that had caused a fair amount of worry. Astronomy hadn't been one of them. In reality, he'd been viewing the Astronomy midterm as more of a formal practice test for the three science GCSE exams he would be taking on the first part of the following week. He took his seat, pulled a quill from his bag and offered Professor Trishna a grin as he took the exam paper and set it on his desk in front of him. Following his usual habit, Sasha took a deep breath, read over the list of questions and allowed himself five minutes to consider his strategy. Then, he leaned over the desk and started writing.

Shell Config: 1s2; 2s2; 2p2________ DefineCorrectly Define the Following Concepts & Terms.4. Gravitation__One of the four fundamental interactions in nature, Sir Isaac Newton's Law of Universal Gravitation describes how any two objects in the universe exert an attractive force on every other object that is proportional to the object's mass. More specifically, every object in the universe attracts every other object with a force that is proportional to the product of their masses and inversely proportional to the distance between the mass center of the two objects. Such that F(G) = G[(m1*m2)/r2]. Earth exerts a gravitational force of approximately 9.8m/s2. 5. Electromagnetism__Another of the four fundamental interactions in nature, electromagnetism is the force that occurs between electrically charged particles. Electromagnetism is responsible for the almost all the phenomena of life (with the exception of gravity) from the physical actions, such as pushing a box with our hand, to functions happening on a molecular level, such as the electrical impulses that set a beating heart's rhythm. __6.Weak Interaction__The Weak Interaction - or Weak Force - is the fundamental force that allows for the radioactive decay of subatomic particles and allows for one type of quark to change into another. For instance, it's through Weak Interactions that protons transmutate into neutrons. This exchange allows for the formation of deuterium which, in turn, allows for fusion in stars, including our sun. Weak interactions occur between both quarks and leptons or any particle whose spin is a half-integer.__ 7. Strong Interaction__The Strong Force, or Interaction, is the force that holds nuclei together, despite the extremely strong repulsive forces between the charged protons neutrons. Though The Strong Interaction is the strongest of the fundamental forces, it is limited by the uncertainty principle and have a very short range.__ 8. Gravity Well __A gravity well is the pull of gravity that a large body in space exerts. The larger the body (the more mass) the more of a gravity well it has. The Sun has a large (or deep) gravity well. Asteroids and small moons have much shallower gravity wells. Entering space from the surface of a planet or moon means climbing out of the gravity well, something that often takes a huge amount of energy. (A gravity well also acts as a distortion of the space-time continuum caused by an object with mass, as experienced by the USS Enterprise in several episodes - though, not really)__ 9. Parallax__A stellar parallax is the distortion of the apparent movement of a nearby star in relation to the background of more distant starts. This can be most often seen in the change of the relative placement and distance between stars as the Earth orbits around the sun throughout the seasons. The relative distance between the stars as they move can be used to calculate distances between celestial objects.__10. Define General Relativity__General Relativity is a theory developed by muggle scientist Albert Einstien, which is the currently accepted mode, having supplanted the original laws proposed by Sir Isaac Newton. In this, Einstien proposes that gravity is caused by the mass of objects warping the fabric of spacetime, and this model also combined space and time into a single entity.

He studied, yes, but for some reason nothing was sticking. He knew when the full moon was, but not sixty years ago! Atoms were difficult for him to figure out too, and some of the definitions, to him, were so similar that they mixed up. Upon taking the midterm, Zel felt like perhaps, this wasn’t a class he should continue to take. Still, he had hope that maybe he could do better on the final. It wasn’t like he was lazy—he just didn’t get it. Asking for a tutor was too embarrassing, because it meant that other students would know that he was an idiot.

It was one of her favorite classes and it had been a pleasure to study for it. She was ready for the test, more than ready. She had read her textbook before returning to Hogwarts in the fall and enjoyed reading and re-reading it in the library. Teagan wasn't the sort of person to get nervous or frightened at exams: she either did well or she didn't. She wasn't an overachiever or academically ambitious but Astronomy.. she just loved it. The moment she looked at the questions on the exam, she smiled happily. This was going to be easy.

Re: [Dec 18th] Astronomy Midterm - NEWT Reply #1 on September 28, 2012, 06:16:24 PM There was only one more class between Sasha and the end of the term. The three-and-a-half month marathon was almost over. Of course, there was still more to come but, for now, Sasha was looking forward to being finished with the first step. He was exhausted - mentally, physically and emotionally. He was ready for classes to be done for the term. There were some exams that had caused a fair amount of worry. Astronomy hadn't been one of them. In reality, he'd been viewing the Astronomy midterm as more of a formal practice test for the three science GCSE exams he would be taking on the first part of the following week. He took his seat, pulled a quill from his bag and offered Professor Trishna a grin as he took the exam paper and set it on his desk in front of him. Following his usual habit, Sasha took a deep breath, read over the list of questions and allowed himself five minutes to consider his strategy. Then, he leaned over the desk and started writing.

Shell Config: 1s2; 2s2; 2p2________ DefineCorrectly Define the Following Concepts & Terms.4. Gravitation__One of the four fundamental interactions in nature, Sir Isaac Newton's Law of Universal Gravitation describes how any two objects in the universe exert an attractive force on every other object that is proportional to the object's mass. More specifically, every object in the universe attracts every other object with a force that is proportional to the product of their masses and inversely proportional to the distance between the mass center of the two objects. Such that F(G) = G[(m1*m2)/r2]. Earth exerts a gravitational force of approximately 9.8m/s2. 5. Electromagnetism__Another of the four fundamental interactions in nature, electromagnetism is the force that occurs between electrically charged particles. Electromagnetism is responsible for the almost all the phenomena of life (with the exception of gravity) from the physical actions, such as pushing a box with our hand, to functions happening on a molecular level, such as the electrical impulses that set a beating heart's rhythm. __6.Weak Interaction__The Weak Interaction - or Weak Force - is the fundamental force that allows for the radioactive decay of subatomic particles and allows for one type of quark to change into another. For instance, it's through Weak Interactions that protons transmutate into neutrons. This exchange allows for the formation of deuterium which, in turn, allows for fusion in stars, including our sun. Weak interactions occur between both quarks and leptons or any particle whose spin is a half-integer.__ 7. Strong Interaction__The Strong Force, or Interaction, is the force that holds nuclei together, despite the extremely strong repulsive forces between the charged protons neutrons. Though The Strong Interaction is the strongest of the fundamental forces, it is limited by the uncertainty principle and have a very short range.__ 8. Gravity Well __A gravity well is the pull of gravity that a large body in space exerts. The larger the body (the more mass) the more of a gravity well it has. The Sun has a large (or deep) gravity well. Asteroids and small moons have much shallower gravity wells. Entering space from the surface of a planet or moon means climbing out of the gravity well, something that often takes a huge amount of energy. (A gravity well also acts as a distortion of the space-time continuum caused by an object with mass, as experienced by the USS Enterprise in several episodes - though, not really)__ 9. Parallax__A stellar parallax is the distortion of the apparent movement of a nearby star in relation to the background of more distant starts. This can be most often seen in the change of the relative placement and distance between stars as the Earth orbits around the sun throughout the seasons. The relative distance between the stars as they move can be used to calculate distances between celestial objects.__10. Define General Relativity__General Relativity is a theory developed by muggle scientist Albert Einstien, which is the currently accepted mode, having supplanted the original laws proposed by Sir Isaac Newton. In this, Einstien proposes that gravity is caused by the mass of objects warping the fabric of spacetime, and this model also combined space and time into a single entity.

Re: [Dec 18th] Astronomy Midterm - NEWT Reply #4 on October 26, 2012, 12:55:42 PM As soon as he looked at the quiz, he knew he was going to fail. He studied, yes, but for some reason nothing was sticking. He knew when the full moon was, but not sixty years ago! Atoms were difficult for him to figure out too, and some of the definitions, to him, were so similar that they mixed up. Upon taking the midterm, Zel felt like perhaps, this wasn’t a class he should continue to take. Still, he had hope that maybe he could do better on the final. It wasn’t like he was lazy—he just didn’t get it. Asking for a tutor was too embarrassing, because it meant that other students would know that he was an idiot.

Re: [Dec 18th] Astronomy Midterm - NEWT Reply #5 on November 05, 2012, 11:10:06 AM Teagan loved Astronomy. It was one of her favorite classes and it had been a pleasure to study for it. She was ready for the test, more than ready. She had read her textbook before returning to Hogwarts in the fall and enjoyed reading and re-reading it in the library. Teagan wasn't the sort of person to get nervous or frightened at exams: she either did well or she didn't. She wasn't an overachiever or academically ambitious but Astronomy.. she just loved it.

It has a very small area of impact, and is very difficult to break.__ 8. Gravity Well __A conceptual model showing the gravitational field of a body. Bodies with greater mass have larger and deeper gravity wells.__ 9. Parallax__A way of measuring distances using the change in position of an object when viewed from two different locations, used to calculate the distance to different celestial bodies.__10. Define General Relativity__A theory developed by Albert Einstien, currently the accepted theory. The theory suggests that gravity is caused by the mass of objects warping the fabric of spacetime, thus combining space and time into a single entity. Although it is flawed, it is the best theory to date.__ Skip to next post
