Course Outline SNC 1DE/1DT      posted 09-05-2009
Welcome to G9 Academic/Enriched Science. This course is designed to give students a base of knowledge of the principles of science that will allow students to be successful in University Level science courses in their senior years. The course consists of four units:
• Physics: Electrical Properties of Matter
• Chemistry: Particle Theory of Matter
• Biology: Cell Functions and Reproduction
• Space Science: Nature and organization of the universe
Term Marks will be calculated as follows:
Knowledge (Tests) 40%
Inquiry and Communications (Labs) 40%
Making Connections (Assignments) 20%
Development of critical thinking skills is also important in this course.
Attendance is crucial to academic success. Students are strongly advised to have a "buddy" in class that they can contact in the event that they are absent, so that they do not fall behind in their work. If a student is legitimately absent from a class (illness, funeral, school activity, etc.)on the day of a test, they will be expected to write the test on the day they return to class. It is the student's responsibility to catch up on missed work.
Although some assignments are completed "in class", many assignments will be handed in later for marking. Students usually have 5 to 7 days to complete assignments. Late assignments will be deducted marks. For up to date information on Chippewa's late policy,refer to your Student Guide.
NOTE: Once an assignment has been marked and returned to the students (usually a week after the due date) any students that have still not submitted the assignment will be given a mark of zero.
The Term Mark will be 70% of the Final Mark with the Final Exam making up the remaining 30% of the Final Mark
For each Term Test there is a practice test that students can try on the ClassBuilder website. This test is similar to (but not identical to) the actual test they will write. This test will help students prepare for the actual test. Students are strongly encouraged to use this resource.





Final Marks Posted!!!      posted 06-21-2009
Your final marks are posted. A new category (called Exam) has been added worth 30% of your overall mark. The mark in this category is your mark on the Final Exam. All other categories have been reduced by 30% to make your Term Mark 70% of your overall mark. The "Final Mark" you see is the mark that will go on your report card.
As a group, marks were quite good. Before the Exam, the class median was 74.5%. The median mark on the Exam was 70% and the overall median mark on the course was a respectable 72.5%!
Well done! It was a pleasure teaching you. Good luck next fall in Gr. 10!

Classroom Expectations      posted 09-05-2007
Proper study habits are essential to student success. The following expectations will help insure that students are successful in this course.
Attendance:
Good attendance is essential to success. Because much of the mark in this course is based on in-class work, students that are absent will fall behind in their work. If a student is absent, it is expected that their parent will call the school attendance office and that the student will check with me to catch up on any missed work. Students are strongly advised to have a "buddy" in class so that they can catch up on handouts and missed notes if they are absent.
Equipment:
Students will need their notebooks, pens and a calculator for this class. Due to safety issues, outdoor clothing and back packs are not permitted in the labs. Also, electronic distractions (such as cell phones, pagers, mp3 players, etc.) are not permitted in the classroom.
PLEASE NOTE: USE OF CELL PHONES AND ELECTRONIC PAGERS IS NOT PERMITTED ON NNDSB PROPERTY.
Work Habits:
Most days students will be taking notes, so keeping an up-to-date, organized notebook is essential to success.
