2 Physical Science 110A Course Description and Outline Fall Semester 2008 PLEASE READ THIS ENTIRE COURSE DESCRIPTION AND OUTLINE THOROUGHLY. YOU WILL NEED THE INFORMATION CONTAINED IN IT IF YOU ARE TO BE SUCCESSFUL IN THE COURSE. This outline will be your guide for the course. You will also receive six homework cover sheets (pink) and six lab report cover sheets (canary). PROFESSOR Robert Beck Clark, Office: N345 ESC, Office Phone Office hours: WTh 11:00-11:50 a.m.; other times by appointment. TEXTS Physical Science Foundations, 2 nd Edition, by Brigham Young University College of Physical and Mathematical Sciences. This is also the Physical Science 100 text. We will study chapters 1-23, 25 and 34. Ideas and Experiments in Physical Science, 2 nd Edition by B.K. Harrison. This is a required supplement for this course. The supplement contains notes for each chapter, review questions, sample tests, and additional supplementary material, particularly in astronomy. It also contains the experiments that you will conduct for the laboratory part of the course. This material should also be useful for you in your own teaching. CLASS MEETINGS The class will meet Tuesdays and Thursdays from 9:10 to 10:40 a.m. in C215 Eyring Science Center. Roll will usually not be taken, but do not use that as an excuse to miss class; you are expected to attend. Missing class often costs you points later on tests. Questions from the class will be invited during the lecture period. Most lectures will feature demonstrations which illustrate the operation of the principles discussed. Announcements concerning the course will be made in class, but may also be advertised in the laboratory. (See below for further explanation of the laboratory.) CLASS IDENTIFICATION NUMBER (CID) Each of you will require a personal class identification number (CID) for this course. The purpose of this number is to protect your privacy. You must enter this CID number on all homework assignments, laboratory reports and examinations in order to receive credit for your work. These items will be returned to you in the Laboratory Room C251 ESC, sorted by the last two digits of your CID number. If you were registered for the class before the first day of classes, your CID number should have been ed to you at your Route-Y address. If you have not received your CID by or have lost or deleted it, you may obtain your CID from the BYU Department of Physics and Astronomy website course page at Select Get a CID Number and then the class Physical Science 110A. Then follow the instructions.

3 COURSE OBJECTIVES Physical Science 110A will give you an opportunity to study the physical universe. You will discover that nature can be understood in terms of fundamental rules and models. There are relatively few fundamental rules and models compared to the wide range of phenomena we encounter in the physical universe. If you learn how to apply these to the world around you, your ability to understand phenomena in the natural world will be satisfying and stimulating. The objectives of this course are twofold: to provide you with a general background in physical science for your own edification, and to provide you with concepts and examples which will help you teach science effectively. These aims overlap to some extent, but not always. The lectures, homework, and exams test your understanding of physical science and provide you with a foundation for teaching science. The lab provides simple personal experiments that you can use in your own teaching. This course will help you search for truth, apply the ideas you learn, and share them with others, consistent with the mission of Brigham Young University. Our treatment is conceptual, not heavily oriented to mathematical problem solving. The important ideas are accessible to you no matter what your previous experience in mathematics or science may have been. They are not trivial, however. The ideas you will study have been selected from among the most profound ideas ever discovered and understood. They have had enormous impact on our culture, our history, even on the ways we think. Serious study will be required if you are to master them. REGISTRATION This course is designed for majors in elementary education, early childhood education or special education. Physical Science 110A covers nearly all the physics, chemistry, and astronomy that is presented in Physical Science 100, but more extensively in order to help prepare you to teach science. If students take this course instead of Physical Science 100, they should also take 110B in order to fill general education requirements. You should not take this course at this time if you are not planning to take Physical Science 110B during the next year. While it is an independent course, Physical Science 110B uses many of the concepts you will learn in this course and should be taken soon after PS110A. GE REQUIREMENTS IN PHYSICAL SCIENCE Students may earn Physical Science GE credit in the Liberal Arts Core by successfully completing both Physical Science 110A and 110B, by successfully completing Physical Science 100, Honors 259, or by passing the appropriate competency exam. PREREQUISITES Students should have reading, writing and mathematical skills at the level required to enter the University. There are no prerequisite courses. In particular, no previous science or math courses are required for success in this course. HOMEWORK ASSIGNMENTS To help you understand the basic ideas of this course, certain questions from the text are assigned, which you must answer in writing and submit as homework. The list is given at the end of this outline. Answer the questions carefully; they will be graded on content and on composition, grammar, and spelling.

4 Since the purpose of the homework questions is to help you understand the ideas of the course, you may wish to read the questions over before you read the text material, then answer them as you read. Appendix D in the text provides hints which can help you find answers to the questions. You are encouraged to discuss assignments with others, but the homework and laboratory reports submitted must be in your own words. Answers copied from the text and/or other student s work is considered plagiarism and a violation of the Honor Code by all involved. Staple your answers to a completed homework cover sheet. Homework is always due at the beginning of class (9:10 a.m.), on the class day following the lecture on each chapter--that is, on Thursday following a Tuesday lecture and on the Tuesday following a Thursday lecture. You may leave early homework in the appropriate box in the laboratory room, C251 ESC. Occasionally, homework late by reason of unusual circumstances may be given credit, but you must obtain approval from the course professor prior to submitting late homework for it to be considered for credit. LABORATORY The laboratory is a very important part of this course. Your particular lab session is determined by the course section for which you are registered. The lab is in C251 ESC. It will be open most hours of the day. The schedule for doing the assigned labs during the term is included in the course schedule at the end of this outline. PLEASE STICK TO YOUR SCHEDULED LAB TIME. DO NOT ATTEND OTHER LABS (except in cases of emergency, or during weeks when there is a University holiday.) The instructions for each Laboratory (except for Laboratories 0, 11 and 12) are included in the supplement Ideas and Experiments in Physical Science. The experimental work which will be done in the lab may occasionally appear elementary, but it is designed to illustrate principles discussed in class. It is important to have "hands-on" experience in understanding the way nature works -- and sometimes nature surprises us! It is expected that the reports you do will provide you with material for your science file in Elementary Education 352 and that they should help you teach science to your own students later. You must come to lab and do the experiments. Roll will be taken. Reporting any experimental work as if you had done it, when you have not done it, is a violation of the Honor Code. You will be expected to do approximately six experiments in each lab, in small groups of students, under the direction of a TA. The experiments use simple materials that are commonly available, so that you can do them later for your own teaching. The requirements and format for each weekly lab write-up will be given to you by your teaching assistant. Even though you will work with others, the written reports must be done individually. Laboratory reports are due at the beginning of your next scheduled lab period. Staple the report to a completed laboratory cover sheet and hand it to your TA at that time, in the laboratory room. Occasionally, laboratory reports late by reason of unusual circumstances, may be given credit, but you must obtain the approval of the course professor prior to submitting the late report for it to be considered for credit.

5 Laboratory 0 is an introduction to the laboratory work. Laboratory 11 involves one home experiment and four astronomical observing projects. These may be done at any time; the report is due near the end of the semester. The assigned work is described in the lab manual. WARNING! We often have cloudy weather in Provo; that makes viewing impossible. Do not leave this lab to the end of the semester, or you may be unable to complete it. Note in particular that one project takes TWO WEEKS; you may wish to begin shortly after the new moon on August 30. At the end of the semester you will be asked to resubmit all of your completed laboratory work collected together, as a portfolio. This portfolio will count as Laboratory 12. EXTRA CREDIT You may earn up to nine points extra laboratory credit, equivalent to one laboratory assignment, by collecting information on several experiments, which you could use in the classroom, and turning it in. Details will be provided to you by your teaching assistant. Normally, no other extra credit projects are allowed. PERSONAL ASSISTANCE The teaching assistants are former PS110A students. Besides being lab assistants, they are also available in the lab for consultation about homework, concepts discussed in the course, and upcoming exams. TAs will be available during most daytime hours M-F. Schedules will be posted. Special times will be posted for Reading days and Final Exam days. The lab phone number is The course professor is also available in his office for assistance, particularly during office hours. You may appeal homework or lab scoring to the PS110A TAs. If you feel that justice has not been done, discuss the matter with your professor. We want you to succeed as much as you do! EXAMS There will be three regular exams and a final exam. These are to be taken in the Testing Center in the Grant Building during the dates indicated on the class schedule. Review materials and sample exams are provided in the syllabus. Help sessions will be provided for each examination. The regular exams will typically have 24 multiple choice questions and three short essay or short answer questions, for a total of 30 points, plus an extra credit question. The final exam -- which will be comprehensive - will have 75 multiple choice questions. Your score on the multiple choice questions will be the number of correct responses, with no penalty for incorrect choices. All exams are closed book and closed notes, with no time limit. You will need only a pencil to take the exams. Supplementary materials (a periodic chart, a list of the chemical elements, etc.) will be provided for exam #3 and for the final. A foreign-language dictionary may be used by those for whom English is not a native language.

6 You must become familiar with the Testing Center schedule and rules. The normal Testing Center hours are: Monday 10:00 a.m. - 7:00 p.m. Tuesday 12:00 noon- 9:00 p.m. Wednesday and Thursday 10:00 a.m. - 9:00 p.m. Thursday 10:00 a.m. - 9:00 p.m. Friday 8:00 a.m. 5:00 p.m. Saturday 10:00 a.m. 2:00 p.m. You will need to present a picture I.D., preferably your BYU I.D. card, to take a test. Do not miss class to take tests. You must be in compliance with BYU standards to be admitted to the testing area. CREDIT AND GRADES The term letter grades for Physical Science 110A will be computed by weighting the exams, homework, and lab in four different ways as follows: homework (text questions) 10% 20% 15% 5% lab 25% 25% 25% 25% regular exams (total) 40% 30% 10% 0 final exam 25% 25% 50% 70% Note that the weight given to the lab is always the same. (However, extra credit lab work -- which will just be added to your total lab score -- would effectively add up to about another 2%.) We will use the highest of these results to assign letter grades. The letter grades will be assigned approximately as follows: A 90% or above A % B % B 80-82% B % C % C 69-72% C % D % D 58-61% D % E below 50% If any test is taken, the semester grade will be determined as described above, with zero assigned to tests which are not taken. The letter grade "I" (Incomplete) is given on a contractual basis with the instructor. An incomplete is only given when extenuating and unavoidable circumstances (serious illness, death in the immediate family, etc.) occur AFTER the twelfth week of a semester.
