Have a good summer!
FINAL EXAM
Final Exam covers Ch.2 thru Ch12 of the text book. It is a comprehensive exam containing
100 multiple choice questions and problems.
Instructional Methods
Face to face thought provoking process
which involves: solving problems, describing concepts, defining scientific terms, drawing
diagrams, and explaining everything in
detail on the white board using dry eraser pen. use of molecular model and over-head
projector when three dimensional presentations are required.
Student Assignments
Final Exam
Final Exam Exemption Requirements:
1.Perfect Attendance, 2. Score average of
90 or above on ch.2 thru Ch.12 tests, and
3. Completed Homeworks on all chapters.
Students may not leave the room during the tests. Students arriving late for the final exam will
not be allowed to take the exam if
another student has already completed the Exam and left the class room.
Assessments
Chapter tests : 50% ( Students will be assessed weekly using 20--30 multiple choice Question /
Problem test on Ch.2 thru Ch.12 of the text book )
Homework : 30% ( Students will turn in selected end of the chapter Questions and Problems
after review session and before the test.
Final Exam : 20% (covers Ch. 2 thru Ch. 12)
Instructional Materials
Text book, Calculator, White board, dry eraser pen, molecular model, over- head
projector, class-size periodic table
