1 SCHOOL OF CHEMICAL AND PHYSICAL SCIENCES Te Wânanga Matû CHEM 114 Principles of Chemistry (CRN points) Course Outline trimester 1, 2012 Course coordinator/lecturers Prof James Johnston (Coordinator) Room LB303 Tel: Dr Jim Pearce Dr Robert Keyzers Room: LB511 Room: AM Tel: Tel: Course Description This course aims to provide an understanding of the principles that underpin the main branches of chemistry. It includes principles of atomic and molecular structure, thermodynamics and kinetics together with an introduction to the systematic chemistry of the main group of elements and transition metals and applications and to a mechanistic interpretation of organic reactivity. CHEM 114 offers the necessary chemical and modern experimental skills to allow students to progress to advanced study in chemistry and in other subjects for which chemistry provides an essential background. The course is designed with a careful balance between depth and breadth and with a view to teaching scientific method as it relates to experimental observations and theoretical models. The immense variety of molecular types and chemical reactions provides a challenge to discover the underlying principles that govern chemical behaviour. Prerequisites CHEM 113 OR 14 credits in NCEA Level 3 Chemistry Course Objectives On passing this course students should be able to: 1. Identify and use chemical principles to solve chemistry related problems, 2. explain how the principles relate to materials and chemical processes, 3. apply principles to the laboratory experiments (where appropriate), 4. clearly communicate ideas in chemistry in appropriate ways using the language and symbols of the discipline, 5. use critical thinking to apply knowledge to novel situations.

2 Course Organisation The course consists of three lectures a week where the basic principles will be introduced. During lectures students will have opportunities to work through ideas and their applications with fellow students. Weekly tutorials provide further opportunities for students to develop their understanding. A weekly laboratory class gives the opportunity to develop practical skills in chemistry and links to the principles presented in lectures. All laboratory classes contribute to the laboratory component of the course. Students are also assessed through weekly assignments, an in-course test and a final examination. BestChoice, an on-line interactive learning tool, will be available for some topics and will be used in some assignments. Course Timetable Lectures: Monday, Wednesday in MCLT101; Tuesday in KKLT301 Laboratory Classes: All laboratory classes are in LB116 Class times are: Thursday, Friday ; Laboratory manuals can be collected from the Laby building School Reception Office LB101. Tutorials: Tutorials are held weekly and begin in the second week of the trimester. Times and rooms are: Monday 9:00 9:50 AM102 Monday 15:10 16:00 AM102 Tuesday 16:10 17:00 KK203 Wednesday 15:10 16:00 AM102 Thursday 9:00 9:50 AM106 Students must select one tutorial and one laboratory class by Friday 9 March. This should be done on-line using Blackboard.

Assessments have been designed to test the course objectives in different ways. Duration Date due / exam period % of final grade Objectives assessed Assignments Weekly, due 10% 1, 2, 4, 5 Wednesday at 5.00 pm Laboratory course Reports due weekly 20% 1, 2, 3, 4, 5 In-course test 1 hour 30 April (6.15 pm) 20% 1, 2, 4, 5 Examination 3 hours 11/6/12 4/7/12 50% 1, 2, 4, 5

3 Mandatory Course Requirements Students must show a satisfactory performance in the laboratory course and assignments and attend the in-course test. Students must gain a minimum of 40% in the final examination with a minimum of 8 marks (out of 33) on each of the three areas, organic, physical and inorganic chemistry. There will be 3 assignments for each section of the course. Laboratory classes begin in week 2 of the trimester with a mandatory laboratory safety session followed by a workshop on Chemical Stoichiometry. Late Work The deadline for assignments is normally Wednesday at 5 pm but late assignments are accepted up to Thursday at 4 pm with a 20% mark penalty. Extensions will be given only in exceptional circumstances, and only if agreed before the due date. In the event of an aegrotat application, regular submission and performance in assignments and laboratories will contribute substantially to the outcome. Workload On average, students should plan to spend a minimum of 10 hours per point in order to achieve an average grade in this course. i.e. 150 hours for a 15 point course, or hours per week, including exam periods. Blackboard This course uses Blackboard ( Course materials and other information will be posted on Blackboard. Students should check Blackboard regularly. Course Information Information relating to CHEM 114, including additions or corrections to the information contained in this sheet, examination timetables, etc. will be displayed on the 100-level notice-board in the foyer area outside the laboratory, LB 116. You should check this board regularly. Information will also be available on Blackboard. Academic Integrity and Plagiarism Academic integrity means that university staff and students, in their teaching and learning are expected to treat each other honestly, fairly and with respect at all times. It is not acceptable to mistreat academic, intellectual or creative work that has been done by other people by representing it as your own original work. Academic integrity is important because it is the core value on which the University s learning, teaching and research activities are based. Victoria University s reputation for academic integrity adds value to your qualification. The University defines plagiarism as presenting someone else s work as if it were your own, whether you mean to or not. Someone else s work means anything that is not your own idea. Even if it is presented in your own style, you must acknowledge your sources fully and appropriately. This includes: Material from books, journals or any other printed source The work of other students or staff Information from the internet Software programs and other electronic material Designs and ideas The organisation or structuring of any such material. Find out more about plagiarism, how to avoid it and penalties, on the University s website:

4 Class Representative A Class Representative will be elected and that person s name and contact details will be available on Blackboard and from VUWSA. The class representative provides a communication channel to liaise with the Course Coordinator on behalf of students.
