Important instructions are in red highlighted. Items that need a response from you are in yellow highlighted. Please put your answers to this activity in RED. Part I- Comparing Permanent Magnets and Electromagnets: 1. Select the simulation “Magnets and Electromagnets.” It is at this link: http://phet.colorado.edu/new/simulations/sims.php?sim=Magnets_and_Electromagnets 2. Move the compass slowly along a semicircular path above the bar magnet until you’ve put it on the opposite side of the bar magnet. Describe what happens to the compass needle. 3. Move the compass along a semicircular path below the bar magnet until you’ve put it on the opposite side of the bar magnet. Describe what happens to the compass needle. 4. What do you suppose the compass needles drawn all over the screen tell you? 5. Use page 10 in your book to look up what it looks like when scientists use a drawing to represent a magnetic field. Describe the field around a bar magnet here. 6. Put the compass to the left or right of the magnet. Click “flip polarity” and notice what happens to the compass. Using the compass needle as your observation tool, describe the effect that flipping the poles of the magnet has on the magnetic field. 7. Click on the electromagnet tab along the top of the simulation window. Place the compass on the left side of the coil so that the compass center lies along the axis of the coil. <--like this 8. Move the compass along a semicircular path above the coil until you’ve put it on the opposite side of the coil. Then do the same below the coil. Notice what happens to the compass needle. Compare this answer to the answer you got to Number 2 and 3. 9. Compare the shape of the magnetic field of a bar magnet to the magnetic field of an electromagnet. 10. Use the voltage slider to change the direction of the current and investigate the shape of the magnetic field the coil using the compass after you’ve let the compass stabilize. Summarize, the effect that the direction of current has on the shape of the magnetic field around an electrified coil of wires. 11. What happens to the current in the coil when you set the voltage of the battery to zero? 12. What happens to the magnetic field around the coil when you set the voltage of the battery to zero? Part II – Investigating relationships- No Answers are written on this document after this point. All three data tables, graphs and conclusion statements go on the Google Spreadsheet that you can download from Ms. Pogge’s website. Experimental Question #1: How does distance affect the strength of the magnetic field around an electromagnet? 1. Using the Electromagnet simulation, click on “Show Field Meter.” 2. Set the battery voltage to 10V where the positive is on the right of the battery (slide the switch all the way to the right). 3. Magnetic field strength (symbol B on the top line of the meter) is measured in gauss (G). You’ll only need to record the value on the top line of the Field Meter. 4. Position zero will be right on top of the coil. Negative number positions will be to the left and positive number positions to the right of the coil. 5. Move the field meter one compass needle to the right and record the value of B at position 1. 6.

SUMMARY ASSIGNMENT SHEET Upload to Turnitin.com by due date. Create an account using Class ID: 10423941 and Password: English. Due Dates: • Peer Response Workshop with Rough Draft: Tuesday, September 8th • First Draft Due (submit for feedback): Thursday, September 10th • Final Draft Due (highlighting, labeling & reflection done in class): Thursday, September 17th What is Summary? Summary is a comprehensive and objective restatement of the main ideas of a text (an article, book, movie, event, etc.) and while the act of summarizing might seem like an easy and obvious undertaking there is a noticeable difference between summarizing and summarizing well. For example, many students, without even realizing it, leave out key information when they summarize because they forget to consider how much their reader already knows about the topic or reading. Be careful to explain fully so readers do not have to guess what you mean. In his textbook, A Brief Guide to Writing from Readings, Stephen Wilhoit suggests that to avoid the pitfalls of unclear or disjointed summaries, they should keep in mind the qualities of a good summary. These qualities include: Neutrality – The writer avoids inserting his or her opinion or interpreting the original text’s content in any way. This requires the writer avoid language that is evaluative, such as: good, bad, effective, ineffective, interesting, boring, etc. Also, keep 1st person (I, we, our, us) out of the summary; instead, summary should be written in grammatical 3rd person (For example, he she, the author, they, etc). Brevity – The summary should not be longer than the original text, but rather highlight the most important information from that text while leaving out unnecessary details and still maintaining accuracy. Independence – The summary should make sense to someone who has not read the text. There should be no confusion about the main content and organization of the original source. This also requires that the summary be accurate—that it not misinterpret any part of the original text. Mastering the craft of summarizing puts students in the position to do well on many assignments in college, not just English essays. In most fields, from the humanities to the sciences, summary is a required task. Being able to summarize lab results accurately and briefly, for example, is critical in a chemistry or engineering class. Summarizing the various theories of sociology or education helps a person apply them to his or her fieldwork. In business, summarizing ideas effectively can be useful in numerous scenarios. The assignment: • Your summary will follow guidelines that integrate both informative and explanatory summary components: Informative summary “simply conveys the author’s main ideas, data, [and] arguments” (Wilhoit 62). Explanatory summary maintains the order of the author’s main points, and also includes the author, title and publication information. • The text: “Who are You and What are You Doing Here?” by Mark Edmundson, pgs. 115-27 The basic structure is as follows: • An Introductory Paragraph including: o The title of the essay, the author’s name, and a brief bio o The topic of the essay—what the text is about o The author’s main idea (essentially your thesis statement) • Body Paragraph(s) including: o Topic Sentences with transitions for each main idea the author addresses o Supporting points following the same order as the article o A concluding sentence that expounds upon, or echoes, the main idea • A Work Cited page that o Includes only the source text Evaluation: A successful summary will include all of the following: • Briefly summarizes the main ideas of the text • Comprehensive, accurate and independent summarization of the text • Objective and neutral restatement of the main ideas • Contain no directly quoted sentences • Clearly introduces the author and title • Body paragraphs that reflect the text’s main ideas • Clear and effective transitions • Mostly free of mechanical and grammatical errors • A correct Work Cited page • Formatted with correct MLA standards • Follows the basic structure of a summary Possible Points: • Peer Response Workshop w/ Rough Draft: 10 points • Final Draft: 80 points • Highlighted revisions and labeling: 5 points • Reflection: 5 points _______________________________________________________________ • Total possible points for the Summary Assignment: 100 Points

ANSWER: Correct Introduction to Potential Energy Learning Goal: Understand that conservative forces can be removed from the work integral by incorporating them into a new form of energy called potential energy that must be added to the kinetic energy to get the total mechanical energy. The first part of this problem contains short-answer questions that review the work-energy theorem. In the second part we introduce the concept of potential energy. But for now, please answer in terms of the work-energy theorem. Work-Energy Theorem The work-energy theorem states , where is the work done by all forces that act on the object, and and are the initial and final kinetic energies, respectively. Part A The work-energy theorem states that a force acting on a particle as it moves over a ______ changes the ______ energy of the particle if the force has a component parallel to the motion. W = -1900 J W W = -1800 J Kf = Ki + Wall Wall Ki Kf Choose the best answer to fill in the blanks above: ANSWER: Correct It is important that the force have a component acting in the direction of motion. For example, if a ball is attached to a string and whirled in uniform circular motion, the string does apply a force to the ball, but since the string's force is always perpendicular to the motion it does no work and cannot change the kinetic energy of the ball. Part B To calculate the change in energy, you must know the force as a function of _______. The work done by the force causes the energy change. Choose the best answer to fill in the blank above: ANSWER: Correct Part C To illustrate the work-energy concept, consider the case of a stone falling from to under the influence of gravity. Using the work-energy concept, we say that work is done by the gravitational _____, resulting in an increase of the ______ energy of the stone. Choose the best answer to fill in the blanks above: distance / potential distance / kinetic vertical displacement / potential none of the above acceleration work distance potential energy xi xf ANSWER: Correct Potential Energy You should read about potential energy in your text before answering the following questions. Potential energy is a concept that builds on the work-energy theorem, enlarging the concept of energy in the most physically useful way. The key aspect that allows for potential energy is the existence of conservative forces, forces for which the work done on an object does not depend on the path of the object, only the initial and final positions of the object. The gravitational force is conservative; the frictional force is not. The change in potential energy is the negative of the work done by conservative forces. Hence considering the initial and final potential energies is equivalent to calculating the work done by the conservative forces. When potential energy is used, it replaces the work done by the associated conservative force. Then only the work due to nonconservative forces needs to be calculated. In summary, when using the concept of potential energy, only nonconservative forces contribute to the work, which now changes the total energy: , where and are the final and initial potential energies, and is the work due only to nonconservative forces. Now, we will revisit the falling stone example using the concept of potential energy. Part D Rather than ascribing the increased kinetic energy of the stone to the work of gravity, we now (when using potential energy rather than work-energy) say that the increased kinetic energy comes from the ______ of the _______ energy. Choose the best answer to fill in the blanks above: ANSWER: force / kinetic potential energy / potential force / potential potential energy / kinetic Kf + Uf = Ef = Wnc + Ei = Wnc + Ki + Ui Uf Ui Wnc Correct Part E This process happens in such a way that total mechanical energy, equal to the ______ of the kinetic and potential energies, is _______. Choose the best answer to fill in the blanks above: ANSWER: Correct Problem 11.7 Part A How much work is done by the force 2.2 6.6 on a particle that moves through displacement 3.9 Express your answer to two significant figures and include the appropriate units. ANSWER: work / potential force / kinetic change / potential sum / conserved sum / zero sum / not conserved difference / conserved F = (− + i ^ ) N j ^ ! = r m i ^ Correct Part B How much work is done by the force 2.2 6.6 on a particle that moves through displacement 3.9 Express your answer to two significant figures and include the appropriate units.

PSY4411 Written Assignment Outline The outline should contain the details of the content you will be including in your final paper (which will be a summary of the journal article). The paper will consist of 2 parts: Part I Description/ summary of the relevant historical topic. This will be determined by the article you selected. It should be approximately ¼ of your total paper. Part II Each section of the article (Introduction, methods, etc) should be summarized as follows: Introduction: Summarize the basics from the background information, and define any key terms. Name the type of study (experiment, correlational study, case study, etc) State the author’s hypothesis and if relevant, describe/ define the independent and dependent variables. Methods: Describe the participants and relevant recruiting/ inclusion/ exclusion information. Describe the variable groups (control vs experimental groups,). Samples sizes for groups do not need to be included. Briefly describe any tests performed by or on the participants (for example, if personality tests were used, it is sufficient to say: The MMPI is a standard personality assessment tool….). Results: A description of the specific statistical tests is not necessary, just a basic summation of the results (ie was there a significant difference between the groups? Was the difference predicted by the hypothesis? Did the data support or refute the hypothesis?). Discussion What do the results mean? If the hypothesis was correct, what does that suggest about the effect of the independent variable on the dependent variable? What further research is suggested? If the hypothesis was not supported, what does that mean? The outline can be structured any way you want, but be consistent; incomplete sentences/ bullet points are okay.
HST 102: Paper 7 Formal essay, due in class on the day of the debate No late papers will be accepted. Answer the following inquiry in a typed (and stapled) 2 page essay in the five-paragraph format. Present and describe three of your arguments that you will use to defend your position concerning eugenics. Each argument must be unique (don’t describe the same argument twice from a different angle). Each argument must include at least one quotation from the texts to support your position (a minimum of 3 total). You may discuss your positions and arguments with other people on your side (but not your opponents); however, each student must write their own essay in their own words. Do not copy sentences or paragraphs from another student’s paper, this is plagiarism and will result in a failing grade for the assignment. HST 102: Debate 4 Eugenics For or Against? Basics of the debate: The term ‘Eugenics’ was derived from two Greek words and literally means ‘good genes’. Eugenics is the social philosophy or practice of engineering society based on genes, or promoting the reproduction of good genes while reducing (or prohibiting) the reproduction of bad genes. Your group will argue either for or against the adoption of eugenic policies in your society. Key Terms: Eugenics – The study of or belief in the possibility of improving the qualities of the human species or a human population, especially by such means as discouraging reproduction by persons having genetic defects or presumed to have inheritable undesirable traits (negative eugenics) or encouraging reproduction by persons presumed to have inheritable desirable traits (positive eugenics). Darwinism – The Darwinian theory that species originate by descent, with variation, from parent forms, through the natural selection of those individuals best adapted for the reproductive success of their kind. Social Darwinism – A 19th-century theory, inspired by Darwinism, by which the social order is accounted as the product of natural selection of those persons best suited to existing living conditions. Mendelian Inheritance – Theory proposed by Gregor Johann Mendal in 1865 that became the first theory of genetic inheritance derived from experiments with peas. Birth Control – Any means to artificially prevent biological conception. Euthanasia – A policy of ending the life of an individual for their betterment (for example, because of excessive pain, brain dead, etc.) or society’s benefit. Genocide – A policy of murdering all members of a specific group of people who share a common characteristic. Deductive Logic – Deriving a specific conclusion based on a set of general definitions. Inductive Logic – Deriving a general conclusion based on a number of specific examples. Brief Historical Background: Eugenics was first proposed by Francis Galton in his 1883 work, Inquiries into Human Faculty and its Development. Galton was a cousin of Charles Darwin and an early supporter of Darwin’s theories of natural selection and evolution. Galton defined eugenics as the study of all agencies under human control which can improve or impair the racial quality of future generations. Galton’s work utilized a number of other scientific pursuits at the time including the study of heredity, genes, chromosomes, evolution, social Darwinism, zoology, birth control, sociology, psychology, chemistry, atomic theory and electrodynamics. The number of significant scientific advances was accelerating throughout the 19th century altering what science was and what its role in society could and should be. Galton’s work had a significant influence throughout all areas of society, from scientific communities to politics, culture and literature. A number of organizations were created to explore the science of eugenics and its possible applications to society. Ultimately, eugenics became a means by which to improve society through policies based on scientific study. Most of these policies related to reproductive practices within a society, specifically who could or should not reproduce. Throughout the late 1800s and early 1900s a number of policies were enacted at various levels throughout Europe and the United States aimed at controlling procreation. Some specific policies included compulsory sterilization laws (usually concerning criminals and the mentally ill) as well as banning interracial marriages to prevent ‘cross-racial’ breeding. In the United States a number of individuals and foundations supported the exploration of eugenics as a means to positively influence society, including: the Rockefeller Foundation, the Carnegie Institution, the Race Betterment Foundation of Battle Creek, MI, the Eugenics Record Office, the American Breeders Association, the Euthanasia Society of America; and individuals such as Charles Davenport, Madison Grant, Alexander Graham Bell, Irving Fisher, John D. Rockefeller, Margaret Sanger, Marie Stopes, David Starr Jordan, Vernon Kellogg, H. G. Wells (though he later changed sides) Winston Churchill, George Bernard Shaw, John Maynard Keynes, Supreme Court Justice Oliver Wendell Holmes and Presidents Woodrow Wilson, Herbert Hoover and Theodore Roosevelt. Some early critics of eugenics included: Dr. John Haycroft, Halliday Sutherland, Lancelot Hogben, Franz Boaz, Lester Ward, G. K. Chesterton, J. B. S. Haldane, and R. A. Fisher. In 1911 the Carnegie Institute recommended constructing gas chambers around the country to euthanize certain elements of the American population (primarily the poor and criminals) considered to be harmful to the future of society as a possible eugenic solution. President Woodrow Wilson signed the first Sterilization Act in US history. In the 1920s and 30s, 30 states passed various eugenics laws, some of which were overturned by the Supreme Court. Eugenics of various forms was a founding principle of the Progressive Party, strongly supported by the first progressive president Theodore Roosevelt, and would continue to play an important part in influencing progressive policies into at least the 1940s. Many American individuals and societies supported German research on eugenics that would eventually be used to develop and justify the policies utilized by the NAZI party against minority groups including Jews, Africans, gypsies and others that ultimately led to programs of genocide and the holocaust. Following WWII and worldwide exposure of the holocaust eugenics generally fell out of favor among the public, though various lesser forms of eugenics are still advocated for today by such individuals as Dottie Lamm, Geoffrey Miller, Justice Ruth Bader Ginsberg, John Glad and Richard Dawson. Eugenics still influences many modern debates including: capital punishment, over-population, global warming, medicine (disease control and genetic disorders), birth control, abortion, artificial insemination, evolution, social engineering, and education. Key Points to discuss during the debate: • Individual rights vs. collective rights • The pros and cons of genetically engineering society • The practicality of genetically engineering society • Methods used to determine ‘good traits’ and ‘bad traits’ • Who determines which people are ‘fit’ or ‘unfit’ for future society • The role of science in society • Methods used to derive scientific conclusions • Ability of scientists to determine the future hereditary conditions of individuals • The value/accuracy of scientific conclusions • The role of the government to implement eugenic policies • Some possible eugenic political policies or laws • The ways these policies may be used effectively or abused • The relationship between eugenics and individual rights • The role of ethics in science and eugenics Strategies: 1. Use this guide to help you (particularly the key points). 2. Read all of the texts. 3. If needed, read secondary analysis concerning eugenics. 4. Identify key quotations as you read each text. Perhaps make a list of them to print out and/or group quotes by topic or point. 5. Develop multiple arguments to defend your position. 6. Prioritize your arguments from most persuasive to least persuasive and from most evidence to least evidence. 7. Anticipate the arguments of your opponents and develop counter-arguments for them. 8. Anticipate counter-arguments to your own arguments and develop responses to them.
