The primary goal of this class is to introduce the student to the basic concepts of Physics. It is intended to be an activity based course. Laboratory skills and simplified calculations will also be taught “as needed” within the course. Applications to real life situations will be emphasized. Topics to be covered will include Linear Motion, Projectile Motion, Newton’s three Laws of Motion, Momentum, Energy, Light, Color, Electrostatics, Electric Fields, Electric Current and Electric Circuits.

Physics is so fundamental a subject that it affects practically all areas of modern life. The impact of physics on society can be seen in most products, processes, and services utilized by society. For example, physicists developed the communications industry for the most part, because of research. Innovations such as the telephone, satellite television, integrated circuits, transistors, cable television, fiber optics, and laser disks all depend on the laws of physics. The applications of physics in the medical field are taken for granted: X-rays, Ultrasonic diagnosis, CAT scans, hearing aids, laser scalpels, pacemakers and radiation therapy. All are based on physical principles.

I know from personal experience the satisfaction that comes from an increased awareness and understanding of the physical world and wish the same for you as you embark on your study of Physics.

EXAMINATIONS/HOMEWORK

Tests will be given after each topic covered. Use of textbooks, notes or study guides will not be allowed during the examination, unless otherwise indicated (Open notebook Test). The questions on the tests will be similar to those done in the assignments. There will be nightly homework assignments. Homework is due AT THE BEGINNING of class as tardy homework results in the loss of points for each day it’s late. Points are given for turning in work on time and attempting questions. We will go over difficult questions during the first ten minutes of class Being allowed to turn in late homework is a privilege. A student who repeatedly turns in homework late may lose this privilege and I reserve the right to make individual arrangements with such a student.The following information is to be in the top right corner of each homework assignment / Lab report

Class Hour:

Packet and Activity Numbers

It is the student’s responsibility to find out if any assignments are missing. Homework assignments must be neat and legible and students must show how they arrived at an answer. Students who have a problem with illegible handwriting can submit typewritten assignments. An illegible assignment or an assignment that shows no work will be returned ungraded and must be redone. Bonus points will be given for neatly presented work.

CLASS PARTICIPATION

Part of class participation is being prepared for class. It is very important that students be on time for class and ready to start when class begins. This means all students must have their books, pencils, pens, and paper on their desk at the start of class. Students will not be allowed to go to their lockers once class has begun.

It is also important for students to participate actively every day in class. This includes asking and answering questions, coming to the board to do problems, and paying attention. Class participation accounts for 20% of the grade.

CLASSROOM RULES

1. Only one person can speak at any given time.

2. Do not interfere with the classroom rights of others to an education

3. Be prepared for class

4. Use of cell phones is strictly prohibited.

FOOD AND DRINK

Food and drink are not allowed in the science department nor anywhere on the second floor of the building. If either are brought into my classroom it will result in a thirty minute detention after school. In science this is an issue of health and safety.

HONESTY

Dishonesty on homework will result in a loss of points for that activity. A second infraction will result in a failing grade for the packet. This applies for both parties.

Cheating on a test will result in:

1. A zero on the test

2. Notification of your parents

3. An unsatisfactory citizenship grade

GRADES

Course Grades will be determined by the percentage of the total points earned throughout the course. (School Policy on Grading System will be used)

Test/Quiz 40%

Participation/ Citizenship 10%

Project 10%

Homework 20%(10% questions from book and 10% webassign)

Lab 20%

Grading Scale:

A =93-100
A- = 90-92
B+= 87-89
B = 83-86
B- = 80-82

C+= 77-79

/ C = 73-76
C- = 70-72
D+= 67-69
D = 63-66
D-= 60-62
F = 59 and below

ATTENDANCE

Tardiness- It is important that you are in class on time and with the necessary materials to begin. Penalties for being tardy are as follows:

1. Loss of 1 points for each tardy.
2. Parents may be notified.
3. Lost points can be made up by serving 1/2 hour for each tardy after school in science.
4. If detentions do not curb excessive tardies, counselors and administration may be contacted

Following an absence you will have 24 hours to have your parents notify school and excuse it. Please attempt to have yourparent/guardian call the attendance office on the morning of your absence. You will be allowed to make up both tests and activities for verified absences. Please refer to your student handbook or a list of what is and is not excused.

Skipping a class will result in two 50 minute detentions and a loss of 20 points for class work (activities) that were missed. In the case of a missed test, due to skipping, a score of zero will be recorded and it can not be made up. An unexcused absence is treated as a cut.

Parents: Please review these classroom policies. My hope is that these guidelines will lead to a very successful year for your son or daughter. I invite you to call me any time you have a concern. My # is
