Honors Freshmen Physics Seton Hall Prep, 2016-17 Instructor: Mr. Trinh E-mail: [email protected] Welcome! This course is your introduction to the world of physics. Physics is the study of how the universe works and the mathematical models and laws that govern it. That is a lot of information so in this course we will limit ourselves primarily to the study of classical mechanics in the areas of kinematics, dynamics, momentum, and energy. Course Goals/Objective To learn to reason as a physicist: o Construct major ideas in physics through observation and testing. o Develop problem solving skills. Experience physics as a dynamic process of discovery, not just a body of knowledge. Appreciate the connection that physics plays in society and with individuals. Class Requirements Textbook: Physics: Principles and Problems; Glencoe McGraw-Hill Text can be taken home. Extra copies will be available for use in class. Workbook: PUM: Physics Union Mathematics; Rutgers, The State University of New Jersey Printouts from this workbook will be provided. Other websites, documents, presentations etc… will be available on the class website at www.shp.org You will need the following with you every day in class: 1. A 1-inch, 3-ring binder with 9 tabbed dividers and plenty of lined 3-hole paper. 2. PENCILS, erasers, and calculators. Keys to Success The best way to do well in this course is to pay attention, stay involved during class, and come prepared. Keep an open mind and never be afraid to ask questions. So that I do not keep answering the same questions over and over again, neat detailed note taking is very important. Being prepared means reviewing your notes on a nightly basis. Evaluation Methods 1. Summative Assessments (100 pts) o Unit Tests – There will be two to three unit tests each trimester. Tests will be announced at least one week in advance. 2. Formative Assessments (20 pts) o Quizzes – Expect at least 1 quiz a week that will be given at the beginning of class so be on time. You will not be given extra time to finish the quiz if you are late. 3. Homework (5 – 20 pts) o Reviewing your notes – I expect you to review your notes on a nightly basis to prepare for next class. While I will not grade you on this it will reflect clearly in the quizzes you take. o Problem Sets – You will be assigned problems from the book or worksheets that will be due on Fridays. 4. Lab Reports (20 – 50 points) o Lab Report – a lab report will be due within one week of completing a lab. To calculate your grade at any point in the trimester, divide the total number of points you earned on all tests, quizzes, classwork, and homework and divide by the total number of points possible. Absent Policy If you are absent, then unless otherwise noted… …all assignments must be handed in the day you get back whether or not we have class. …expect to make up any tests or quizzes on the day that you return either before or after school. …you are responsible for any notes or handouts you missed that day. Check with your classmates first before you check with me. Late Work and Resubmission All work handed in after the due date will lose a full letter grade of each day late. Late work cannot be resubmitted. The process of resubmission will be outlined in a separate document on our class website. Classroom Policies and Expectations 1. Be on time and ready to learn. This means coming to class with your notes out and whatever assignments due, ready to be handed in at the beginning of class! 2. Don’t be afraid to volunteer your ideas, no matter how crazy. They thought Einstein was crazy... and he was, but at least he was right about relativity. 3. Respect each other’s ideas, otherwise no will want to volunteer their ideas. Keep an open mind, science never progressed with a closed one. 4. Don’t be afraid to ask questions either. Class is about learning not knowing the right answer. 5. Work hard for me and I’ll work hard for you. On my end this means you can expect: …that I will always try and make myself available for extra help whenever possible provided that you come and ask for it. …that I will always answer your questions to the best of my knowledge and if I do not know the answer I will find out for you. …that I will have your tests, quizzes, and homework graded on time. Laptop/Electronic Device Policy Laptops and other devices such as tablets are discouraged in class. While the school allows such devices for note taking in my experience students are more often distracted by a computer and take poor notes as a result. In addition, we will regularly draw diagrams or pictures, which is very difficult or impossible to do in such a device unless you have a stylus. So while I will allow the use of a laptop or other typing device (excluding cellphones) I reserve the right to take away your laptop/electronic device privileges in my class if I decide it is a distraction to yourself or others. Help Access: Help class is for you to ask additional questions or clear up any confusion about the material. That being said the purpose of help class is not to reteach the material so come to help class prepared, otherwise I cannot help you. At the very least you should come to help class knowing the key terms. All help access will be in Room 340 unless otherwise noted. If these times do not work for you please schedule something with me. Tuesday Activity Period: 9:25-10:05 AM Wednesday After School: 2:45-3:30 PM Thursday Activity Period: 8:45-9:25 AM Honors: As an honors class I will expect more from you in terms of the quality of your work. In general, we will cover more material in greater depth and do additional lab activities. For this to be possible we will keep a much quicker pace compared to a regular class. At the end of the first trimester I will review these policies. If everything is working then we will continue with them, if not I reserve the right to change them.
