Chemistry Course Outline and Syllabus 2015 – 2016


Chemistry Course Outline and Syllabus 2015 – 2016
Science Department - Mira Loma High School
Teacher: Phe Bach, Ed.D.
Email: pbach@sanjuan.edu; Room: D-4
Twitter/Instagram/fb/Linkedin @PheBach

MLH Vision/Mission Statement:
Embracing diversity and valuing excellence, Mira Loma High School's mission is to inspire and educate each student toward academic achievement, critical thinking, intrinsic success, and responsible contributions to a peaceful international society by providing innovative, rigorous, student-focused instruction through a rich tradition of high-quality programs and dynamic activities in a safe, compassionate, and collaborative learning community.

Course Goals:
- Achieving the defined California State Standards for High School Chemistry.
- Fulfilling the requirements of IB Middle Years Programs.
- Preparing students for college and presenting chemistry material that applies to their daily life with a positive attitude.

Organization/Course Standards: This course is followed closely the Prentice Hall Chemistry textbook.  It is organized into ten units according to California State and SJUSD’s Standards for chemistry.  Students will understand the following topics:

Unit 1 – Introduction to the Methods of Chemistry:
Measurements and Calculations; Lab Equipment and Lab Safety
Unit 2 – Matter and Changes / Scientific Measurement:
            Matter, elements and compounds, mixtures, chemical reactions. Measurements and their uncertainty, Basic SI systems, Density.
Unit 3 – Atomic Structure, Electrons and Periodic Behavior
Atoms – The building blocks of Matter; Structure of the atoms; arrangement of Electrons in Atoms, the Periodic Law, Periodic Trends
Unit 4 –Chemical Bonding and Molecular Structure:
Chemical bonding; Structure of Covalent Molecules, Salts, and Metals
Unit 5 – Chemical Names and Formula/Conservation of Matter:
Chemical Formulas and Compounds, Chemical Equations and Reactions.
Unit 6 – Stoichiometry
            The arithmetic of equations, chemical calculations, limiting reagent and percent yield.
Unit 7 – Gas Laws / Gas Behavior:
Physical Characteristics of Gases, Gas Laws, Molecular Composition of Gases
Unit 8 – Solids, Liquids and Solutions / Acids and Bases:
Liquids and Solids, Properties of Solutions and Solution Concentration, Acids and Bases,  Characteristics of Acids and Bases, Titration, calculating pH, neutralization of acids and bases.
Unit 9 – Electrochemistry, Thermochemistry and/or Nuclear Chemistry
Electrochemical cells, reduction-oxidation reactions; The flow of energy, heat in changes of states, nuclear radiation, nuclear transformations, Fission/Fusion of Atomic nuclei.
Unit 10 – Introduction to Organic and Biochemistry.
Subjects outside of the State Standards, covered after the Content Standards Test in early May.
GRADING POLICY- ACADEMIC GRADE:
The Academic grades will be based on the following breakdowns:
a.     Classwork/Homework, standards testing, presentations 25%
b.     Portfolio, Quizzes, and Unit Tests 25%
c.     Laboratory notebook, lab quizzes, project and lab reports 25%
d.     Comprehensive final exam 15%
e.   Participation and attendance 10%

Grading Scale: Course grades will be assigned according to SJUSD’s standard grading practice:
100% - 90% = A || 90% - 80% = B || 80% - 70% = C || 70% - 60% = D || Below 59.9% = F
I’ll use the normal grade scale with “plus” and “minus”.
I’ll not curve my tests, but I DO give extra credits.

Extra Credits:
            You made earn up to 1.0% per semester. Bonus points are awarded from time to time at the instructor’s discretion for a variety of little extra reasons such as bring materials for the lab, writing summary of science/chemistry articles, asking brilliant questions and seeking the answer, helping out the room/lab, etc… or conducting an original research or writing an exceptional research paper and this work is no “Mickey Mouse” project. Ask the instructor for more information.

CITIZENSHIP GRADE:
Your classroom behavior, attendance and working ethic determine your citizenship grade.

Besides HONESTY and PERSONAL INTEGRITY, RESPECT is the key. Being courteous, mindful and respectful to fellow students, T.A., substitute, your instructor, and our classroom settings are expected at all times. Unnecessary acting out, put down, talking, trashing class/campus, or other immature behaviors will lead to lowering of your citizenship grade. Finally, the citizenship grading policy will comply with Mira Loma and San Juan School Districts’ policies. This includes adhering to all rules in our handbook. For example, after 3 tardies (<30mins) results in parent-called plus 1 hour detention and after each truancies (>30mins) will results in lower 1 citizenship grade.

MAKE UP POLICY:
When you are absent, it is your responsibility to turn in work that was due during your absence the following day you’re back. If you missed a lab/test, it must make up within ONE week or it will results in a zero. Late works will NOT be accepted unless it is an excused absence. Homework are turn in every Wednesday and Friday. Late work is no longer accepted. All grade discrepancy must take care of within one week of posted grade. I’ll be available to help before school ‘til 7:45AM, during lunch or by appointment. (Just letting me know or emailing me you’re coming).

Code of Conduct: Classroom policies, policies on attendance, tardiness, dress code, and behavior, are addressed in the student handbook, will be implemented along with district policies.
