Biology 12: Course Outline
Biology 12 is an introductory Biology course in which you study: The Processes of Science (A), Cell Biology (B), and Human Biology (C).
Instructors: Ms. Dow and Mr. Fox
Course Website: http://dowscience.weebly.com/ and http://foxsciencecentre.weebly.com/
Text: -Biology: Concepts and Connections, 8th edition, by Reece, Taylor, Dickey and Simon. This is a newer edition than what was used for Biology 11. -Web content for Campbell, Concepts and Connections, 8e and access to Mastering Biology can be obtained by visiting www.pearsonschool.com/access, and following the instructions provided by your teacher.
Supplies:You will need a pen, pencil, highlighters, small metric ruler, eraser and large binder containing lined and unlined paper. Lab reports and drawings should be inserted into the binder at the appropriate locations. Certain labs may require a calculator.
Laboratories:Participation in the process of science is a necessary component in the understanding and appreciation of any science course. Students are expected to complete all the labs and present individual lab write ups. Diagram guidelines are as follows:
All diagrams should have an appropriate, underlined title All diagrams are to be drawn with a sharp pencil. A pencil and ruler are to be used for label lines. All microscope diagrams must include the magnification. Marks will be deducted for diagrams that do not adhere to above.
Referencing: All referencing will be in APA format. Accurate referencing and in text citation is expected for assignments.
Assignments: Students will complete one main research assignment during the year. More information will be given to you at the end of September.
Tutorials:Extra help can be arranged simply by requesting a time which is convenient for both of us.
Critical Thinking
Biology 12: Course Outline 2014-2015 Page 1
The Science Department considers the development of the critical thinking skills of our students to be essential to their success in science and in life. Critical thinking is a complex process with many essential facets. In order to address this complexity we have chosen areas of focus for each grade. These are indicated in the table below. As students’ progress through these grades they will continue to master the skills from earlier grades. The skills chosen as a focus for later grades will also not be ignored in the earlier grades. Each student report card will include a comment on the progress being made in the grade specific area of critical thinking. The table below indicates the areas of focus per grade.Critical Thinking Skills Grade Ask pertinent questions 7Adjust opinions when new facts are found. 7Admit a lack of understanding or information where necessary 7Look for evidence 8Examine problems carefully 8Analyze data 8, 9Define criteria 9Weigh evidence and draw reasoned conclusions 9Reject incorrect or irrelevant information 10Assess statements and arguments 10, 11Identify assumptions and biases 10, 11Consider a variety of explanations 11, 12Identify missing information 11Suspend judgement until all facts have been gathered and considered

Evaluation:To achieve at your best level in Biology, you should read the text material before it is covered in class and review it after class and before tests. Read actively; attempt to answer the chapter review questions; refer to the extra material on the text website, ask pertinent questions. Enrich your knowledge by reading journals and articles related to what we are studying in class.
Your grade in Biology 12 will be determined as follows: 30% final cumulative school examination
The remaining 70% of your mark will be determined as follows: 40% unit tests 15% laboratory work and other assignments 10% quizzes based on daily work 5% Research project
Note: Because Biology is an activity-oriented course, excellent attendance will assist you to achieve not only your best results but also your best level of satisfaction in the course.The Collingwood test and plagiarism policies will be adhered to.
Absence from tests: The Collingwood test policy will be adhered to:
After an absence, students will write the test no later than the day of the second class following their return. If they fail to do so, they will receive a zero. Students will, however, be expected to demonstrate his/her knowledge of the material. The only exceptions will be in the submission of a doctor’s note. Teachers will notify parents via an email or phone call before the final day that the writing can occur. For further information on test writing expectations, please refer to the Collingwood School Academic Integrity Document: Plagiarism & Test Taking Agreement.
*Retests will occur every Thursday morning at 7:10am.
Late Submissions Late submissions will inevitably affect the effort mark given for the course as well as the grade for that assignment. Instances do occur, however, when a late submission may be necessary. If you are going to be absent, ask for an extension in advance. The Collingwood late policy (as outlined below) will be in effect.

follicular phase, ovulation, and the luteal phaseC15.4 describe the sequence of events in the uterine cycle, with reference to
menstruation, the proliferative phase, and the secretory phaseC15.5 describe the control of the ovarian and uterine cycles by hormones
including gonadotropin-releasing hormone (GnRH), follicle-stimulating hormone (FSH), luteinizing hormone (LH), estrogen, and progesterone
C15.6 describe the hormonal changes that occur as a result of implantation, including
– production of human chorionic gonadotropin (HCG) to maintain the corpus luteum
– increased production of progesterone by the corpus luteumC15.7 describe a positive feedback mechanism involving oxytocin
