This NCEA course offers the students a total of 20 credits, of which 8 credits are internally assessed papers, and 12 are assessed through external examinations in November. The three external examinations come from both Chemistry and Science areas. Sitting two Chemistry examinations in the three hours allocated will give students more opportunity to excel. The remaining examination paper will be sat during the Science three-hour examination timeslot which takes place on a different day. This means that for boys doing any of the specialist science subjects, they will be sitting external papers on at least two of the examination days in November.
However, as most are keeping career options open, it is likely that the majority will carry on with Chemistry in Year 13. Assessment Students will complete two internal achievement standards. The two internal achievement standards count for 7 of the available 20 credits in chemistry. The course achievement standards are: AS 91910 Carry out a practical investigation into a substance present in a consumer product using quantative analysis. (4 credits – internal) AS 91164 Demonstrate understanding of bonding, structure and energy changes. (5 credits – external) AS 91165 Demonstrate understanding of the properties of selected organic compounds. (4 credits – external) AS 91166 Demonstrate understanding of chemical reactivity. (4 credits – external) AS 91167 Demonstrate understanding of oxidation- reduction. (3 credits – internal) Additional topics are contained in the Year 12 course tomaintain greater consistency and extension for students. The olympiad training programme is offered to all students fromTerm3 onwards. The three external standards will be assessed in a three hour end-of-year examination timeslot. Trial examinations will be held during the year to help prepare students.

Description The Year 12 course includes study of the
underlying principles in the behaviour of many common substances, solutions, solids, energy, oxidation-reduction reactions, analytical work and organic chemistry. Patterns of behaviour and the understanding of principles are emphasised to a greater extent than recall of knowledge. Students take on a greater role in chemical investigations in this course, with the introduction of specialist laboratory equipment and practical based assessment tasks. Students will learn a variety of techniques for measuring and testing chemical substances to develop a holistic understanding of chemical systems at a deeper level. Practical demonstrations and experiments are explored on a frequent basis throughout the course. Students with a leaning towards practical and descriptive science can do well at this level, with skills in mathematics being an added advantage. To attempt the Year 12 course, a reasonable performance in Year 11 NCEA Chemistry is preferred. Students who have done well in Year 11 NCEA Science may study Year 12 Chemistry provided they have achieved AS 90944. These students may find the transition to the Year 12 course challenging and should consult the HoD of Chemistry prior to the end of Year 11. Some students terminate their study at this point.
