• Course Description

               This course presents a study of matter and energy. This branch of physical science is called Physics. Physics deals with the properties, changes, interactions, etc. of matter and energy. Physics is the study of the physical world. The goal of physics is to use a small number of basic concepts, equations, and assumptions to describe the physical world.


    ·         To conduct field and laboratory investigations using the scientific method and make informed decisions using critical thinking and scientific problem solving.

    ·         To gain knowledge on how science has built a vast body of changing and increasing knowledge described by physical, mathematical and conceptual models.

    ·         To understand how a system works; how its components relate to each other and the whole. Students will also understand the basic properties of systems that can be described in terms of space, time, energy and matter. Change and constancy occur in systems and can be observed and measured as patterns. Students will make predictions of what will happen next and what can change over time.

    ·         To use scientific investigations, methods and models to understand the natural world. Students should also understand that methods, models and conclusions built from these investigations have limitations and based on new discoveries, they are constantly modified to more closely reflect the natural world.



            This course is divided into the following units:

    ·         1 – Measuring and Describing Motion

    ·         2 – Motion in One Dimension

    ·         3 – Gravitational Force

    ·         4 – Forces and Laws of Motion

    ·         5 – Free-body Diagrams

    ·         6 – Vectors and Motion in Two Dimensions

    ·         7 – Momentum and Impulse

    ·         8 – Work-Energy Theorem and Energy Transformations

    ·         9 - Conservation of Energy and Momentum

    ·         10 – Thermodynamics

    ·         11 – Wave Properties and Behaviors

    ·         12 – Sound

    ·         13 – Electromagnetic Waves and Applications of Waves

    ·         14 – Electrical and Magnetic Forces

    ·         15 – Electric Circuits

    ·         16 – Atomic Physics and Photoelectric Effect

    ·         17 – Applications of Atomic and Nuclear Physics

    Physics Class Expectations

    ·         All rules in your student handbook must be observed at all times.

    ·         Our classroom and laboratory room are integrated so you are expected to follow the classroom rules and laboratory safety rules at all times.

    ·         All assigned tasks must be turned in on time. Assignments turned one day late will receive only 80% credit, and 5 points deductions for each additional day, unless the student has an EXCUSED ABSENCE SLIP TO MAKE UP for the missed classwork within one week from the date of absence to receive 100% credit.

    ·         When you answer an assigned task, make sure you write your answer in complete sentence to receive full credit.

    ·         When you solved mathematical problems, your work must show complete solution. You must follow the problem-solving steps – IGUESS:

         I – Illustrate

         G – Given

         U – Unknowns

         E – Equations

         S - Substitute

         S – Solve


    1. Be respectful.
    2. Be responsible.
    3. Be prepared.
    4. Be positive.
    5. Do not talk when the teacher is talking.
    6. The use of cell phones and listening devices are not allowed in the class.



    1. Verbal praise
    2. Positive notes, stickers
    3. Extra points
    4. Calls
    5. Participation in Field Trips(NASA, Houston Museum of Natural Sciences, Colleges/University /Plant Visits)



    1. Verbal warning
    2. Call to parents/guardian

    3.   Lunch, After school, and Friday detention (3:15-4:15)

            4.  Parent-Teacher Conference

            5.  Discipline Referral to the Principal



    Class grades are based on a percent weight-point system as follows:

    Tests                               - 30%

     Daily Work                    -20%

     Quizzes                          -20%

    Laboratory                     - 20% (Lab report, participation)

    Homework                      -10%

    Total                                 100%

    *Note: Student’s equivalent grade on the test, daily work, quizzes, and homework is determined using the raw score conversion table. He/she should get score of 70% or higher on those components in order to earn a passing grade.


    • Students who are not able to turn in homework on time will be assigned a Friday detention. Points will be taken off for late homework. ( 10 points/day)
    • Students will be permitted to make up assignments for excused absences within a one (1) week period. Failure to comply within a specified time frame will result to a grade of 0 for that particular assignment.


    • The students will be assigned to do major projects which are related to the Unit Learning Focus every nine weeks. The projects can be done individually or as a group.
