CHEMISTRY SYLLABUS GRADE 11 Grade 11-Chemistry The Chemistry curriculum is designed to continue student investigations of the physical sciences that began in grades K-8 and provide students the necessary skills to be proficient in chemistry. This curriculum includes more abstract concepts such as the structure of atoms, structure and properties of matter, and the conservation and interaction of energy and matter. Students investigate chemistry concepts through experience in laboratories and field work using the processes of inquiry. Grade 11 - Curricular Content The course has been developed taking into consideration the standards used by the National Academies of Science, science as inquiry, physical science, life science, earth and space science, science and technology, personal and social perspectives, history, and nature of science.

The teacher continuously assesses student performance and progress, as evidenced by in-class task commitment, finished written pieces, on-demand writing, homework, tests and quizzes, threaded discussion responses, class notes, and daily preparation. Evaluation System: Student grades will be calculated as follows: Tests, projects and quizzes 60% Laboratory work 25% Homework 15% Semester grades are developed based upon the following formula: Quarterly Grades (average) 80% Exam Grade or Semester Project 20%
