    Course overview:

    Chemistry is the science concerned with the composition, structure, and properties of matter. Topics include the changes matter undergoes during chemical reactions, various interactions of atoms, molecules, crystals. Chemistry incorporates concepts of energy and entropy related to spontaneity of chemical processes. In Chemistry, lecture and class notes will be combined with laboratory investigations where students will use the scientific method to make informed decisions using critical thinking skills.



    Expectations levels are high in Principles of Technology.  Students are expected to come to class with their materials and prepared to learn.  They are to ask questions and become actively involved in their own learning by participating in all class activities and discussions.  All homework, projects, labs and assignments are due on the due date.  If a student is absent, he/she is responsible for getting all make up work and returning it within the time allotted according to the student handbook.  Missed exams are to be made up before or after school, or at lunch.  All forms of cheating and plagiarism will not be tolerated.


    Required supplies:

    It is required that each student have a composition notebook for a journal for keeping notes and a binder for returned papers, handouts, etc. This journal will be graded, and students are expected to be able to locate and produce a paper if needed.  Donations of Kleenex, dry erase markers and hand sanitizer are greatly appreciated and will receive extra credit (3 per nine weeks).



                    Tests/Projects                                                   40% 

                    Daily Work                                                         60%

    These percentages will make up 85% of the student’s grade, with the remaining 15% coming from the district required final exam.


    Course Schedule:

    The following is a tentative course schedule.

    Semester 1                                                       Semester 2

    Laboratory Management                               Stoichiometry

    Matter                                                               Gases

    Periodic Table                                                  Solutions

    Chemical Bonding                                           Acids, Bases, & Reactions

    Chemical Formulas                                         Thermochemistry

    Mole Concept                                                   Nuclear Chemistry

    Chemical Equations & Reactions                  Chemistry Connections


    Lab Safety:

    Science is a lab based class and it is of utmost importance that students become familiar with and follow all lab safety rules, lab procedures, and oral instructions. A CHISD safety contract will be completed and turned in by each student before they are allowed to participate in a lab activity. Failure to turn in the safety contract will prevent a student from participating in lab and may result in a zero for the grade. In Addition, all students will score 80% or better on a basic safety test before they will be allowed to participate in a lab.


    Exams and major projects:

    Students will be given adequate notice of upcoming exams and project due dates. These will be posted in the classroom and website. There will be three tests each 9 weeks.



    Tutoring will be offered before school according to the schedule posted in the classroom. Students are expected to come prepared with questions about the topic on which they are requesting help.


    School policies, attendance, tardies, discipline

    All campus and district rules and policies will be enforced. Students should be respectful of school and personal property and behave in an appropriate manner at all times.

    I am looking forward to working with your student.
