Course Guidelines – in brief
Assessment
Assessment and attendance requirements for each course
will be discussed with you and
must be agreed upon within the first two weeks of semester. As a
guide to discussion thecourse convenor will usually provide you
with a document suggesting assessment.
It is RSC policy that you must obtain a pass mark in the final
exam to pass all courses.
Students who fail to attend a laboratory session cannot submit a
written report on thatlaboratory for assessment.
Safety
You must wear the appropriate protective clothing (laboratory
coat, safety glasses andcovered shoes) to participate in a
practical class. Students who do not comply will not bepermitted to
work in the laboratory. Laboratory coats and safety glasses may
bepurchased from the campus University Bookshop. (More
information). Please refer to theChemistry 1 lab manual for
information on the Research School of Chemistry’s policy onwearing
contact lenses in the laboratory.
Prerequisites
You must have completed the correct prerequisite or have written
approval of the course
convenor for a valid enrolment in a course. Please refer to
http://info.anu.edu.au/studyat/ or enquire at the Faculty of
Science Office (Frank Fenner Building, Bldg 42).
Student Representation
Five students from first-year and one student from each of
second and third year (as wellas Honours and PhD) will be elected
in the first two weeks of semester to represent theiryear group on
the Chemistry Department’s Teaching and Learning Committee.
(MoreInformation)
Policy on the Submission of Written Material
This policy reflects the ANU Code of Academic Honesty in
Learning and
Teaching:http://info.anu.edu.au/policies/Codes_of_Practice/Students/Other/Academic_Honesty.asp
It is the responsibility of each student to ensure:
• Work submitted for assessment is genuine and
original;• Appropriate acknowledgement and citation is given
to the work of others;• He or she does not knowingly assist
other students in academically dishonest
practices;• Familiarity with the expectations for academic
honesty both in general, and in the
specific context of particular disciplines or courses, where
these expectations are
clearly outlined in faculty and course guides and handbooks.

For Chemistry students the definitions and penalties are set out
below.
Plagiarism
Plagiarism is copying, paraphrasing or summarising, without
acknowledgement, any workof another person with the intention of
representing this as the student’s own work. Thisremains plagiarism
whether or not it is with the knowledge or consent of that other
person.
Direct copying falls under the definition of plagiarism. When
students work together, theymust be sure to write independently,
and not in collaboration with another student or groupof students.
The purpose of assessment is to evaluate each student’s mastery of
skillsand knowledge. It is acceptable for students to compare and
discuss results ofexperiments of essay concepts, but written work
must reflect individual effort and allwritten work must be the
student’s own.
To avoid plagiarism students must correctly acknowledge the work
of others. If studentstranscribe, quote, paraphrase or summarise
the ideas obtained form the work of others,they must identify the
source and author of the original work and provide a
bibliography.
Penalty: zero marks. Serious, and in particular repeated
instances of academicdishonesty, constitute misconduct and need to
be dealt with under the ANU DisciplineRules.
Multiple Submissions (Recycling)
Recycling is the submission of work for assessment, which has
been previously presentedby the same student for another assessment
either at ANU or elsewhere. In some cases,lecturers will
specifically allow this practice. If no specific provision is made
then itconstitutes academic dishonesty when assessment is submitted
a second or subsequenttime.
Penalty: zero marks. Serious and, in particular repeated
instances of academicdishonesty, constitute misconduct and need to
be dealt with under the ANU DisciplineRules.
Fabrication or Falsification of Data
Fabrication of research is the representation of data,
observation or other research activityas genuine, comprehensive
and/or original when it has been arrived at through othermeans.
These may be inventing data, using data gathered by other
researchers withoutacknowledgement, or deliberately omitting data
to obtain the apparently desired results.
Any data presented as the result of laboratory work (in
the form of drawings, graphs,tables or written work) must be true
and representative of your findings.
Penalty: zero marks. Serious and, in particular repeated
instances of academicdishonesty, constitute misconduct and need to
be dealt with under the ANU DisciplineRules.
Collusion
Collusion is the representation of original work of several
persons as the work of a singlestudent. Collusion needs to be
distinguished from collaboration, defined for the purposesof this
document as work jointly undertaken and produced within permissible
parameters.
Another form of collusion involves representing the work
of one good student as the work

of several individual students, in for example the situation
where students A, B and C paystudent D to do the assignment and
give them each a copy, which they then rephrase andsubmit as their
own.
Penalty: zero marks. Serious and, in particular repeated
instances of academicdishonesty, constitute misconduct and need to
be dealt with under the ANU Discipline
Rules.
Cheating
Cheating in this code means the breach of rules regarding formal
examinations, ordishonest practice in informal examination, tests
or other assessments. Examples includethe use of prohibited
material or equipment for unfair advantage, consultation with
otherpersons during the course or the assessment where this is
prohibited.
Penalty: zero marks. Serious and, in particular repeated
instances of academicdishonesty constitute misconduct and need to
be dealt with under the ANU DisciplineRules.

Chemistry – The Central Science
There are currently two first year Chemistry courses available
at ANU:• Chemistry 1 (CHEM1101) offered in semester 1,
and• Chemistry 2 (CHEM1201) offered in semester 2.
Chemistry 1 and 2 together correspond to a full year course in
general chemistry.
Both Chemistry 1 and Chemistry 2 have an associated Honours
Pathway Option (HPO).The HPO is strongly recommended for students
with a strong background/interest inchemistry (from College,
Science Summer School, Olympiad or equivalent) and forstudents who
intend to go on with chemistry in second year.
It is expected that all students in the PhB or Honours degree
programs enrolled inChemistry 1 or Chemistry 2 will complete the
HPO. The latter consists of an additionaladvanced lecture
each week which extends the core lecture material given in
Chemistry 1
and Chemistry 2. Students should note that Chemistry 1 is a
necessary prerequisite forenrolment in the second semester course
Chemistry 2 .

Chemistry 1 Outline
Chemistry 1 is a one-semester chemistry course designed to cover
the needs of a widevariety of students by offering a broad
introduction to a range of chemical concepts. Thecourse serves not
only as a sound foundation in chemistry, but also as a useful
and
necessary background for those whose main interests lie in
engineering, the earth, orbiological sciences. Where possible,
chemical principles are illustrated by applications tobiological or
geological systems; the emphasis, however, is distinctly
on developing aknowledge and understanding of a basic set of
chemical concepts and facts.
Course Aims:
As it is assumed that students in Chemistry 1 will have
completed at least a minor in highschool/college chemistry, the
main emphasis lies in consolidating and extending thefactual basis
of chemistry and developing a sound comprehension of the
basicchemical principles and concepts.
The general aims are to:1. consolidate a factual background in
the language of chemistry (nomenclature),
basic structural aspects, and major / typical reaction types.2.
develop an understanding of the basic concepts of atomic structure,
bonding,
energy and entropy, and the kinetic theory of reactions.3.
develop an understanding of how various structural features
determine the main
reactivity patterns of simple chemical compounds.4. develop
problem solving skills, both qualitative and quantitative, in areas
deriving
from aims 1 - 3.
Where possible, examples will be chosen to illustrate the
application of these concepts
and principles that are of relevance to biologists, engineers,
geologists, or to the widercommunity.
Later year courses in chemistry broaden and deepen students’
comprehension ofchemical concepts, principles, and their
inter-relationships. These higher courses alsofurther develop
students’ abilities to apply these principles to a wide variety of
chemicalsystems and problems of current interest or importance.
Course Structure, Content, and Objectives:
The course material will follow fairly closely the structure and
content of the two settextbooks (see below). Development of the
chemical concepts and topics is described in
the following syllabus. The syllabus also sets out the main
learning objectives for eachsection; these objectives will be
closely allied to the assessment process.
Text Books:
The prescribed textbook is:Chemistry Cubed by Andy Burrows, John
Holman, Andy Parsons, Gwen Pilling andGareth Price,
1st Edition, Oxford University Press, 2009, ISBN:
9780199277896 [around$80].
The following two text books are also suitable.M. S. Silberberg,
Chemistry – The Molecular Nature of Matter and Change, 4th
Edition,
McGraw-Hill, 2006.

Laboratory CourseChemistry is essentially an experimental
science. The laboratory program consists of avariety of
experimental exercises designed to:
1. illustrate and develop competence in a range of chemical
techniques and
manipulative skills.2. emphasise (particularly in first term)
the importance of a quantitative analyticalapproach to chemical
systems.
3. develop an awareness of the scope and limitation of
experimental observation andaccuracy.
4. illustrate chemical topics, principles and concepts.
Attendance
Laboratory classes (3 hr sessions) will run for most of the
semester, beginning in thesecond week. Attendance at ALL LABORATORY
sessions is compulsory. Thesubmission of ALL LABORATORY
REPORTS is compulsory.
A pass in the prescribed laboratory work in each semester
is required in order to gain apass in the Chemistry 1 and 2
courses.
A schedule of experiments will be displayed on the
noticeboard outside the ground floorstudent laboratories as well as
on the CHEM1101 WATTLE site.
Signing Up
There will be a number of laboratory class groups operating on
Monday to Fridayafternoons. Choose one group which is
compatible with your timetable and sign up for
this online using the “Laboratory Allocation” link on the
CHEM1101 WATTLE homepagehttp://wattle.anu.edu.au. Discuss any
timetable clashes immediately with the First YearCoordinator (Dr
Mark Ellison, Room 1.33) or the First Year Laboratory Technician
(MsBozena Belzowski).
If you have satisfactorily completed the laboratory component of
this course or a similarone, you may be eligible for a lab
exemption. Please discuss the matter with the First YearCoordinator
as soon as possible.PLEASE NOTE: A student who consumes any
laboratory chemicals or ofcompounds that have been prepared in the
laboratory will be excluded from thecourse.
Fees
A laboratory manual and the first set of lecture notes
will be available for purchase fromJohn McLelland in the Teaching
Administration area of the Research School of Chemistry(Building
33). There is a fee of $40 for these items. The fee also covers the
other lecturebricks which will be issued during the semester. You
will need to pay the $40 fee atScience Shop:
http://scienceshop.anu.edu.au/. Please bring your receipt to
JohnMcLelland in the Chemistry Office to collect your lecture notes
and lab manual.

Equipment
You need a laboratory coat, a pair of safety glasses and a
notebook to record data in forlaboratory classes. Writing data on
bits of paper is not good scientific practice.Laboratory coats
($29.95) and safety glasses ($7.50) can be purchased from
theUniversity Bookshop.
Molecular Models
Three dimensional (3D) molecular structures will be used
throughout the course.Stereochemical concepts (chemistry in 3D) can
most readily be appreciated throughmanipulation of suitable
molecular models. To facilitate this, exercises involving
molecularmodels have been incorporated into the laboratory course.
These limited exposures tomolecular models are, however, inadequate
and you will most likely need to refresh yourknowledge of the many
stereochemical features on a frequent basis.
For this purpose, a Molymod molecular model kit is available for
purchase from theUniversity Bookshop ($59.95). Two types of Darling
Model Kits ($14 and $20) are also
available to be purchased. Payment is made through the Science
Shop(scienceshop.anu.edu.au) and the kits can be collected from
John McLelland (onproduction of a receipt) in the Chemistry
Administration Office (Building 33, level 1).
Software
The Department has purchased a self-learning software package in
organic chemistryentitled Introduction to Organic Chemistry by
Falcon Software. This package will enableyou to revise and
consolidate lecture material, and the use of interactive animations
willassist you in grasping difficult concepts in organic chemistry.
The software is readilyaccessible on the PCs in the Department as
well as on the PCs in the Teaching and
Learning Technology Support Unit (TLTSU). In addition, there are
on-line learningmaterials accompanying the text-books.
The Online Resource Centre to accompany Burrows: Chemistry3 is
now liveat: http://www.oxfordtextbooks.co.uk/orc/burrows/
Mastering Chemistry on-line Quizzes
There are 12 on-line quizzes (approximately weekly) for you to
complete during thesemester. On-time completion of these 12 quizzes
contributes to 6% of your semestermark in Chemistry 1.
Each quiz will be available for 1 week. Each quiz can be first
accessed on the Sundaystarting the week and will close at midnight
on the following Sunday. Each quiz willcontain questions relevant
to the previous week’s lecture content and will take about
30-40minutes to complete.
Once the quiz has closed you can still access the quiz to use
for revision, but you will beunable to submit the answers to the
quiz.
If you are struggling to submit a quiz on-time please see the
First year Convenor (Dr MarkEllison) before the close of the
quiz.
