More Sci- Than Fi, Physicists Create Antimatter Physicists working in Europe announced yesterday that they had passed through nature s looking glass and had created atoms made of antimatter, or antiatoms, opening up the possibility of experiments in a realm once reserved for science fiction writers. Such experiments, theorists say, could test some of the basic tenets of modern physics and light the way to a deeper understanding of nature. By corralling [holding together in groups] clouds of antimatter particles in a cylindrical chamber laced with detectors and electric and magnetic fields, the physicists assembled antihydrogen atoms, the looking glass equivalent of hydrogen, the most simple atom in nature. Whereas hydrogen consists of a positively charged proton circled by a negatively charged electron, in antihydrogen the proton s counterpart, a positively charged antiproton, is circled by an antielectron, otherwise known as a positron. According to the standard theories of physics, the antimatter universe should look identical to our own. Antihydrogen and hydrogen atoms should have the same properties, emitting the exact same frequencies of light, for example. . . . Antimatter has been part of physics since 1927 when its existence was predicted by the British physicist Paul Dirac. The antielectron, or positron, was discovered in 1932. According to the theory, matter can only be created in particleantiparticle pairs. It is still a mystery, cosmologists say, why the universe seems to be overwhelmingly composed of normal matter. Dennis Overbye, More Sci- Than Fi, Physicists Create Antimatter, New York Times, Sept. 19, 2002 74 The author of the passage concerning antimatter incorrectly reported the findings of the experiment on antimatter. Which particle mentioned in the article has the charge incorrectly identified? [1] 75 How should the emission spectrum of antihydrogen compare to the emission spectrum of hydrogen? [1] 76 Identify one characteristic that antimatter particles must possess if clouds of them can be corralled by electric and magnetic fields. [1] 77 According to the article, why is it a mystery that the universe seems to be overwhelmingly composed of normal matter ?

PHYSICAL SETTING/PHYSICS continued Directions to the Teacher Follow the procedures below for scoring student answer papers for the Physical Setting/Physics examination. Additional information about scoring is provided in the publication Information for Scoring Regents Examinations in the Sciences. Use only red ink or red pencil in rating Regents papers. Do not attempt to correct the student s work by making insertions or changes of any kind. On the detachable answer sheet for Part A and Part B 1, indicate by means of a checkmark each incorrect or omitted answer. In the box provided at the end of each part, record the number of questions the student answered correctly for that part. Students responses must be scored strictly according to the Scoring Key and Rating Guide. For open-ended questions, credit may be allowed for responses other than those given in the rating guide if the response is a scientifically accurate answer to the question and demonstrates adequate knowledge as indicated by the examples in the rating guide. Fractional credit is not allowed. Only whole-number credit may be given to a response. Units need not be given when the wording of the questions allows such omissions. Raters should enter the scores earned for Part A, Part B 1, Part B 2, and Part C on the appropriate lines in the box printed on the answer booklet, and then should add these four scores and enter the total in the box labeled Total Written Test Score. Then, the student s raw score on the written test should be converted to a scaled score by using the conversion chart that will be posted on the Department s web site: http://www.emsc.nysed.gov/osa/ on Thursday, January 25, 2007. The student s scaled score should be entered in the labeled box on the student s answer booklet. The scaled score is the student s final examination score. All student answer papers that receive a scaled score of 60 through 64 must be scored a second time. For the second scoring, a different committee of teachers may score the student s paper or the original committee may score the paper, except that no teacher may score the same open-ended questions that he/she scored in the first rating of the paper. The school principal is responsible for assuring that the student s final examination score is based on a fair, accurate, and reliable scoring of the student s answer paper. Because scaled scores corresponding to raw scores in the conversion chart may change from one examination to another, it is crucial that for each administration, the conversion chart provided for that administration be used to determine the student s final score. [3] PHYSICAL SETTING/PHYSICS continued Please refer to the Department publication Regents Examination in Physical Setting/Physics: Rating Guide for Parts B 2 and C. This publication can be found on the New York State Education Department web site http://www.emsc.nysed.gov/osa/scire/scirearch/phyratg02.pdf. Teachers should become familiar with this guide before rating students papers. Scoring Criteria for Calculations For each question requiring the student to show all calculations, including the equation and substitution with units, apply the following scoring criteria: Allow 1 credit for the equation and substitution of values with units. If the equation and/or substitution with units is not shown, do not allow this credit. Allow 1 credit for the correct answer (number and unit). If the number is given without the unit, do not allow this credit. Penalize a student only once per equation for omitting units. Allow full credit even if the answer is not expressed with the correct number of significant figures.

[9] Regents Examination in Physical Setting/Physics January 2007 Chart for Converting Total Test Raw Scores to Final Examination Scores (Scaled Scores) The Chart for Determining the Final Examination Score for the January 2007 Regents Examination in Physical Setting/Physics will be posted on the Department s web site http://www.emsc.nysed.gov/osa/ on Thursday, January 25, 2007. Conversion charts provided for previous administrations of the Regents Examination in Physical Setting/Physics must NOT be used to determine students final scores for this administration. Submitting Teacher Evaluations of the Test to the Department Suggestions and feedback from teachers provide an important contribution to the test development process. The Department provides an online evaluation form for State assessments. It contains spaces for teachers to respond to several specific questions and to make suggestions. Instructions for completing the evaluation form are as follows: 1. Go to www.emsc.nysed.gov/osa/exameval. 2. Select the test title. 3. Complete the required demographic fields. 4. Complete each evaluation question and provide comments in the space provided. 5. Click the SUBMIT button at the bottom of the page to submit the completed form.
