    You are expected to be in class when the bell rings. Come every day to class, but especially come to EVERY LAB!  Labs are difficult to make-up.  You will have two days to make-up an excused absence for full credit.  If you are Brown-Slipped, you are in attendance at school and your work will be due as if you had been in class that day (you do not get an extra day!), so think ahead and pick it up the day before, before school, after school, or between classes.  Any time you are absent YOU are responsible for getting the work that you missed and making arrangements to come in and make up a missed lab, test or quiz within the allotted time!  No credit will be given for tests/quizzes taken after the next test/quiz, labs turned in after the next lab.

    ·         A student is tardy if he/she enters the classroom after the bell has rung.

    ·         If a student does not fulfill the obligations of the attendance contract, consequences as outlined in the student procedures handbook will result.

    ·         Excessive absences and tardiness could result in the loss of credit (Student procedures Handbook J-1561) and/or a class schedule change may be assigned by administration.

    Late Work: 

    Late homework and late classwork are accepted and will receive three quarters (3/4) credit until the unit test.  WORK LEFT INCOMPLETE OR MISSING after the unit test WILL RECEIVE NO CREDIT. 

    Late labs will also be accepted, but there will be a graduated penalty of 5% for each day they are late (up to 25% off).  No credit will be given for labs turned in after the START of the NEXT lab.

    Extra Credit: 

    Extra credit may be available from time to time, but will be in addition to (not as a replacement for) assigned course work, and will not exceed 2% of the total grade.

    Electronic Devices: 

    Cell phones are not acceptable calculators!  As per district policy, no electronic devices are allowed.  If seen or heard:

    1. 1st offense – warning from teacher/staff member to put item away, reminder of school rules
    2. 2nd offense – warning from teacher/staff member to put item away, reminder of school rules, and device will be confiscated for remainder of period.
    3. 3rd offense – device confiscated, PARENTS/GUARDIAN will be responsible for picking up the device from the dean. Multiple infractions may result in a referral, as per the discipline policy. 

    Note: 

    Chemistry is a demanding course.  Daily, consistent effort is the key to success.  If you encounter difficulties, don’t hesitate to ask for extra help BEFORE it is too late.  I wish you a successful school year!

    • Teaching Philosophy: 

    • Teaching is caring to touch lives for ever.


    • Classroom Policies/Rules:

    *      I am here to teach; you are here to learn. I will do my job; you will do yours, and together we will utilize this year wisely and beneficially.

    *      A positive attitude is the key to success. Let’s keep it all the times.

    *      Class Policies: A policy is a plan that guides our actions:

    To do things effectively, we have to adhere to some common sense policies. So, to be successful in learning, you need to follow some basic classroom rules! I call them my class policies. Following these few basic policies will help keep our class environment peaceful and productive. If you choose not to adhere to the policies, there will be logical consequences.

    1. Be ready (prepared) to learn. –books, planner, notebooks, paper, pen, sharpened pencils, etc.
    2. Always act and speak in an appropriate manner. Raise hand before speaking. Respect the rights, opinions, and property of others. Work without disturbing anyone.
    3. No food, or drink allowed.
    4. No personal electronics allowed.
    5. Listen and follow directions.
    6. Place trash in trash can and recyclables in the appropriate recycling can.

    -          If you have questions about assignments, check with the teacher at an appropriate time.  Do the work at home.

    -          If you missed a test because of an excused absence, inform the teacher and arrange a time to make up the test after school. You will have one day to make-up work for every day you are absent.

    *      While You Are Working:

    -          Make sure you read or listen to the directions about your work and understand the directions.

    -          If you didn’t understand, quietly ask for help from other students sitting around you.

    -          If you are asked to help, be polite and help.

    -          Talking to each other should be no louder than a whisper.

    -          Respect each other and be friendly.

    -          Use your time wisely.  Put forth your best effort to finish your work on time.

    *      After You are Finished:

    -          Check your work and the directions one more time to see if you missed anything or did something incorrectly.

    -          Check to see if the heading is written correctly on your paper.

    -          If the assignment is to be turned in, do so.
