Chemistry Higher
RECOMMENDED ENTRY:
While entry is at the discretion of the Principal Teacher, candidates will normally be expected to have attained one of the following awards or its equivalent:
• Standard Grade Chemistry at Grades 1 and 2
• The Intermediate 2 Chemistry course or its component units together with
• Standard Grade Mathematics at Grades 1 and 2 or Intermediate 2 Mathematics.
(The preferred entry level from Standard Grade is based on achievement in the Knowledge and
Understanding and Problem Solving elements.)
The Higher Chemistry course is divided into three units.

(c) Knowledge and understanding of patterns in the Periodic Table is clearly shown in appropriate ways.
(d) Knowledge and understanding of bonding, structure and properties is clearly shown in appropriate ways.
(e) Knowledge and understanding of the mole is clearly shown in appropriate ways.
2. The World of Carbon (40 hours)
Performance criteria
(a) Knowledge and understanding of fuels is clearly shown in appropriate ways.
(b) Knowledge and understanding of nomenclature and structural formulae is clearly shown inappropriate ways.
(c) Knowledge and understanding of reactions of carbon compounds is clearly shown in appropriate ways.
(d) Knowledge and understanding of uses of carbon compounds is clearly shown in appropriate ways.
(e) Knowledge and understanding of polymers is clearly shown in appropriate ways.
(f) Knowledge and understanding of natural products is clearly shown in appropriate ways.
3. Chemical Reactions (40 hours)
Performance criteria
(a) Knowledge and understanding of the chemical industry is clearly shown in appropriate ways.
(b) Knowledge and understanding of Hess’s Law is clearly shown in appropriate ways.
(c) Knowledge and understanding of equilibrium is clearly shown in appropriate ways.
(d) Knowledge and understanding of acids and bases is clearly shown in appropriate ways.
(e) Knowledge and understanding of redox reactions is clearly shown in appropriate ways.
(f) Knowledge and understanding of nuclear chemistry is clearly shown in appropriate ways.
In addition all candidates will be expected to carry out the Prescribed Practical Activities listed below.

Examination Arrangements
The examination will consist of one paper of 2 hours 30 minutes with a total allocation of 100 marks.
To gain the award of the Course, candidates must pass the internal assessments for the Units. In addition the candidate must meet the standards targeted by the external assessments.
The paper will consist of two sections
Section A Fixed-response questions 40 marks
Section B Extended-answer questions 60 marks.
Section A will be made up of 40 multiple-choice questions.
In section B approximately 6 marks will be allocated to questions that draw on the candidates’ experience of the prescribed practical activities.
Of the 100 marks in the paper between 57 and 62 marks will be allocated to the assessment of knowledge and understanding and between 38 and 43 marks will be allocated to the assessment of problem solving.
Up to 10 marks over the paper can be allocated to questions based on content which is common to Standard Grade and Intermediate 2, with assessment at a level appropriate to Higher.
Candidates will be expected to answer all questions.
Higher Downloads
The following downloads give pass papers for revision purposes as well as a data booklet in pdf format. In additional you will notice there are also booklets on each unit as well as a Problem Booklet to assist you in your revision. You may also wish to visit the Evans2chemweb site. Details of user ID and login are available from your teacher.
