Regents Physics Syllabus Room E-MAIL ADDRESS: WEB PAGE: POST SESSIONS: Mrs. LaBarbera 207 dlabarbera@vcmail.ouboces.org http://www.vcsd.k12.ny.us//Domain/248 TUE. – FRI. COURSE DESCRIPTION The New York State course in Regents Physics is an excellent introduction to physics for the college bound senior. Many students embark on their university career without knowing exactly what they want to study. Taking physics in high school can open many doors for students who find that they want to major in a technical area. Students who take high school physics can obviously expect to do far better in university physics courses than those students who have not. Taking a course in physics gives the student a stronger foundation in problem-solving strategies and critical thinking. These are exactly the areas in which many universities and employers are complaining that candidates are not skilled enough! The Regents course is comprehensive in scope with each subject is treated with the proper depth for the average student. Students are prepared for, and expected to take, the Regents Physics exam in June. There are two prerequisites for this course. First, students should have completed Regents Biology, Regents Earth Science and Regents Chemistry. Without previous science experience, it will be difficult to do well in this class. Second, students should have completed two Regents Math exams. This course requires the understanding of algebra and fundamental knowledge of geometry that you gain from your math class. We meet every day for 40 minutes with an additional 40 minute lab period every-other day. At the completion of this course students should have a strong conceptual understanding of required topic and be able to complete all required physics laboratory experiments.

Thus, each quarter and the Regents Exam will comprise 20% of the final course grade. Midterm The physics department administers a district-wide midterm exam during "Midterm Week" in January. This exam includes Regents level questions and will count for 20% of the student's second quarter grade. Tests and Exams A test is a 25 point assessment with a blend of multiple choice and extended response questions. Tests are typically given in the middle of a large unit of instruction. An exam is given at the end of each unit and is a two part assessment. Part One of the assessment will consist of 25 multiple choice questions. Part Two of the assessment will consist of 25 points worth of extended response questions. The two parts of the exam carry equal weight to each other and to all other tests and exam parts given in the same quarter. All tests are built using questions from past Regents exams and/or questions based directly on Regents exam questions. Lab All labs will be documented in a personal lab-notebook which will be kept in the classroom. Students will be required to complete at least 1200 minutes of lab (about 30 labs) time with a complete lab report in order to pass the course. Project/Formal Lab One Project per quarter will be designated as a "formal lab". This project will be subjected to strict grading criteria and will be important in teaching students how to produce high quality lab reports. Class work / Participation Class work includes any formal or informal assessment of student work or preparedness for class. Most of the class work grades will consist of "Do Now's", "Exit Slips", and "Activities". Participation includes attendance, attentiveness to tasks during class and ability to work well with others. Participation grade heavily rewards effort on the part of the student. Homework Homework is assigned from your textbook or from the http://www.castlelearning.com website. Homework is assigned everyday; it will take an average student about half an hour to complete. Homework will be collected and graded daily. According to research, completion of homework in high school produces a gain of about 24 percentile points. Quizzes Quizzes will be given in the weeks in which no test is scheduled. They generally consist of five to fifteen questions that directly reflect the questions assigned on previous homework. 2 Regents Physics Syllabus Mrs. LaBarbera REQUIRED SUPPLIES Lab notebook Binder (suggested) Protractor with ruler calculator CLASSROOM RULES OF CONDUCT 1. No electronic devices are allowed during school. 2. Come to class on time. Standing outside the door and rushing in after the bell has begun to ring will constitute a tardy. You must be INSIDE the door when it begins ringing to be counted on time. If you are on time for five weeks, you will get one homework pass. 3. Begin do now activity within one minute after the second bell. Do now is part of participation grade. 4. Attend to personal needs before coming to class. I have been instructed not to give passes to lockers and to limit passes, so please do not ask for a pass unless you have a true emergency. If you used less than two passes for five weeks, you will get one homework pass. 5. Remain in your assigned seat unless you have permission to get up. Throw scraps away at the end of the period on your way out. 6. Bring required materials every day. If you bring all you supplies for a quarter, you can get a quiz pass for the quarter. 7. Talk only when permitted. Be aware of the situation since quiet talking is allowed in some situations and speaking to the entire group without raising your hand may be allowed in others. I will remind you once and expect compliance. 8. Use polite speech and body language. Unkind teasing and impolite behavior is unacceptable. 9. Do not cheat. Students caught cheating will receive a zero and a phone call home. Both the student who shares his work for an independent assignment AND the person who copies it will suffer the same consequences. I expect you to do your own work and to be sure no one can copy it. 10. Sign in when you are late or when you are back from a leave; Sign out when you leave the class. 3 Regents Physics Syllabus Mrs. LaBarbera TENTATIVE SCHEDULE Unit Overview of Topics Math Prep A review of the various mathematical tools students will need during the year.
