Weslaco High School

Chemistry I SYLLABUS

2012-2013

Instructor: Ms. Eunice Chihuahua

Room #: R3

Conference Period: Period 1B (8:10-10:00 a.m.)

Course Description: Chemistry is the study of the composition, structure, properties and reactions of matter. This class is a laboratory based course that focuses on the observation, and manipulation of matter, communication of data, measurement of chemical quantities, prediction of chemical phenomena, and safe manipulation of laboratory apparatus and material. Instruction in this course targets all the Texas Essential Knowledge and Skills (TEKS) specifications for chemistry.

Course Structure: This course consists of class work, lectures, laboratory investigations, projects, homework, quizzes and exams. Grades will be calculated as follows:

Class Evaluation

·  Six weeks grades

o  40% Daily Grades

o  20% Labs

o  15% Quizzes

o  25% Exams

·  Semester grades:

o  20% Semester Exam

o  80% Average of six weeks grades

Final grades will be calculated by averaging the two semester grades. Students caught cheating or plagiarizing on any assignment will receive a ZERO on the assignment. No grade changes will be made after the end of the six weeks.

Make Up Work and Late Work

·  Any work turned in late can receive a maximum grade of 70.

·  Late work will only be accepted one week after the due date.

·  It is the students’ responsibility to make up the assigned coursework when absent.

·  Extra Credit is offered at the instructor’s discretion.

Classroom Rules

1.  Respect

2.  Be Prepared

3.  No cell phones or multimedia devices unless permission is given

Tutoring: At times chemistry concepts can be confusing. I am available most days from 7:30-8:00 am. I am also available at other times by appointment. School wide science tutoring is available as posted.
