Text: Physics: Principles and Problems: Zitzewitz and Neff:1995
Physics is the study and investigation of the physical world around us. The physical world deals with motion of bodies, light, sound, electricity, magnetism, and gravity. Basically every thing that makes our world operate. We will use the lab exercises to better understand the physical world while also learning proper lab techniques. Students taking this course should have a very good understanding of Algebra and be able to do calculations with confidence.
I assume that the majority of the students taking Physics are considering attending a college after graduating from high school. Therefore one of my goals of this class is to prepare you for college level work. With this in mind we will, at times, discuss things that may not be directly connected with Physics, but rather things that may help you be successful in college.
The material we will cover in the 36-week school year will usually be covered in about 14 weeks in a college course; they will also go into much more depth than we will here. At times you may feel we are covering a lot of material quickly, and we may be. Live with it! YOU ARE CAPABLE OF MORE THAN YOU THINK.
The study of Physics can be difficult and sometimes intimidating. One thing to remember is the fact that the study of Physics has NEVER killed anybody. If you are confused or don’t understand something ASK FOR HELP. I will be available after school if you need assistance. Don’t be too scared or embarrassed to ask for help. This can be a tough class; I will try to help you any way I can to make it easier.
The information covered in each chapter is given below. The objective for every chapter is that students learn and understand this information.

**Some chapters or sections of chapters may be added or deleted at the teacher’s discretion in order to meet the needs and abilities of students and to maintain proper pacing. This is a lot of material to cover in two semesters, but the more we cover the better the background you will have for college courses. I will, however, try to maintain an appropriate pace so that you can learn the material well.

Mr. Ohlde’s Classroom Rules
1. Any homework, quiz, or test that is to be handed in should not be written in red, orange, or pink ink, any fringes from spiral bound notebooks need to be removed.
2. The following information should be in the top right hand corner.
3. Use proper grammar and complete sentences on all written assignments. Points will be deducted if this rule is not followed.
4. All students are expected to contribute in group projects and assignments, I will be watching for this. If someone isn't doing his or her part please speak with me.
5. Bring your text, notebook, calculator, paper, and pencil to every class. If this becomes a problem you may start losing points.
6. Don’t touch or mess with any material or equipment until I instruct you to. During lab exercises we will sometimes be using materials that can cause permanent personal injury; horseplay or fooling around will not be tolerated.
7. I know accidents happen, but if you break equipment due to carelessness you may be required to pay for replacing it.
8. I am not a big fan of extra credit, if you want and need extra credit you will need to do extra work. Extra credit will be something above and beyond the work we are doing in class, not just an extra worksheet or two. Keep track of your scores so that you are aware of your present grade; ask me if you have any questions about how to calculate your grade. By keeping track of your grade you can react early if it is lower than you like.
9. Anyone caught cheating on a quiz or test will receive a zero. Just so everyone understands what I think constitutes cheating I will give several examples. Using notes of any kind is cheating. This includes information saved in the memory of calculators, written on paper, or on the tables; I will check for these. Looking at another student’s paper is cheating, likewise carelessly or intentionally letting someone look at your paper is cheating. If a student isn’t present when a test or quiz is given and needs to make it up at a later date it is cheating for any student to discuss items that are on the test with that student. Talking between students during a test will be considered cheating. If a situation arises that is not stated above Mr. Ohlde along with the school’s administrator will decide if it is cheating.
10. Do not use cell phones in class, the school policy concerning cell phones will be enforced in this class. If a phone is being used for any purpose it will be turned in to the principal.
While I understand there will be times when turning in a late paper is unavoidable you need to understand the importance of turning in assignments in a timely manner. Each student will be allowed three late papers without penalty, after that no credit will be given. If you are going to be gone for a planned activity (school function, family outings, or hunting etc.) you are expected to turn in your homework before leaving.
Grading and Weighting:
Your grades will be divided into four categories, homework, quizzes, notebooks, and tests. Since it is not unusual for students to work together on homework it is difficult to determine if the student turning in the homework completed and understands the homework. I have no problem with students working together as long as one is not simply copying another student’s work. For this reason the value of the score is reduced. The value given for tests and quizzes is increased because the student turning in the work did it themselves, I know the work is theirs and it reflects what they have learned. You are required to keep all work that is returned to you in a three ring binder I will check these once each quarter and they will be worth 10% of your total grade.
Following are the four categories and their weighting; homework 20%, notebooks 10%, quizzes & labs 20%, and unit exams 50%.
CALCULATING YOUR GRADES
Your total grade consists of four parts with the following weightings.
Homework: 20% of grade
Quizzes and labs: 20%
Tests: 50 %
This may sound somewhat confusing, but here is how you calculate your total grade.
Take the points earned in each category divided by the total points possible in each category, multiply that by the weightings and add all these answers together for your grade. I know you are still confused so here are some examples.
Homework: total points earned = 455
total points possible = 500
Quizzes: total points earned = 27
total points possible = 30
Notebook: total points earned = 10
total points possible = 10
Tests: total points earned = 95
total points possible = 100
Homework: 455/500 = .91 .91 X 20% = .182
Quizzes : 27/30 = .90 .90 X 20% = .18
Notebook: 10/10 = 1.00 1.0 X 10% = .10
Tests: 95/100 = .95 .95 X 50% = .475
Total grade .937 or 93.7% which is an A
Now, remember that if you are caught cheating on a test you will receive a zero on that test. Let’s see how that may affect your grade. I will use the same numbers except for the test.
Quizzes : 27/30 = .90 .90 X 20% = .18
Tests: 0/100 = 0.0 0.0 X 50% = 0.0
Total grade .462 or 46.2% which is an F
Not only is it an F it is a very low F. The only way to bring that grade up is to do well on the next test. Since we have tests only every 2-3 weeks you would be ineligible for any activities for at least that amount of time. So if you are thinking about cheating be aware of the consequences and don’t expect any sympathy if you are caught.
