Te Marau: Mātai Matū (Chemistry) Te Taumata: 2 Kaiako: Matua Matt Cassidy Curriculum level: 7 Curriculum document: Medium of instruction: NZC English Tauira need to have gained 12 credits from T1 Pūtaiao in 2016 and passed AS 1.3 Carbon Chemistry before entering this subject. If they have not passed AS1.3, they need to talk to Matua Matt and pass a make-up exam for it, before classes start. This course is a multi-level course, so T2 and T3 tauira will be studying together. Tauira will also be dual-enrolled with Te Kura Pounamu (NZ Correspondence School) and Nga Taiatea Wharekura. Students are expected to be independent learners, as they will need to do a lot of self-directed study in class, but with the assistance of Matua Matt. Wahanga 1 Te Kaupapa: Quantitative Chemistry (I) In this module ākonga will be carrying out quantitative analysis. Collecting titration data that contains at least three titre values that fall within a range of 0.4 ml; the average titre value must be within 0.5 ml of the expected outcome. Solving quantitative problems that involve at least two steps and require application of relationships such as n=m/m and c=n/v. Titration calculations must be carried out correctly using only concordant titre values. Tauira will need to pay a $20 bond if they borrow an exam booklet. This is returned when the booklet is returned in good condition at the end of the year. AS91161 CHEMISTRY AS2.1 Internal assessment Term 1 Week 9 Resubmissions in Term 1 Week 10 or earlier
Wahanga 2 Te Kaupapa: Organic Chemistry (I) In this module ākonga will demonstrate understanding of the properties of selected organic compounds Constitutional and geometric (cis and trans) isomers Classification of alcohols and haloalkanes as primary, secondary or tertiary Solubility, melting and boiling points Chemical reactions Chemical reactions are limited to: Addition reactions of alkenes with H 2 /Pt, Cl 2, Br 2, H 2 O/H +, hydrogen halides (including identification of major and minor products on addition to asymmetric alkenes), polymerisation. Substitution reactions of: alkanes with halogens (limited to mono-substitution), alcohols with hydrogen halides, PCl 3, PCl 5, SOCl 2, haloalkanes with ammonia and aqueous potassium hydroxide Oxidation of: primary alcohols to form carboxylic acids with MnO 4-, alkenes with MnO 4 - Elimination of (including identification of major and minor products for asymmetric reactants): water from alcohols, hydrogen halides from haloalkanes, acid base reactions of carboxylic acids and amines. AS91165 CHEMISTRY AS2.5 Term 2 Week 10 External assessment A series of about 3-4 mock exam questions will be given throughout the module.
Wahanga 2 Te Kaupapa: Quantitative Chemistry (II) This achievement standard will be available to tauira during Oranga Wairua/Tinana from about Week 7 Term 2. Tauira who have a track record of independent study will be able to do this standard. In this module ākonga will be carrying out an investigation in chemistry involving quantitative analysis. Collection of quality data which includes standardising the standard solution(s) and control of significant variables Accurate processing of the data to reach a valid conclusion Providing evidence of the mathematical steps used to process the experimental data presenting a report that contains: o a description of the procedure in sufficient detail for the investigation to be duplicated o a conclusion that links the processed data to the purpose of the investigation o an explanation of how the procedure used contributed to the collection of quality data AS91387 CHEMISTRY AS3.1 Term 2 Week 9 Internal assessment Resubmissions in Term 2 Week 10 or earlier
Wahanga 3 Te Kaupapa: Organic Chemistry (II) In this module ākonga will demonstrate understanding of the properties of selected organic compounds Organic compounds are limited to those containing one or more of the following functional groups: alkene, haloalkane, amine, alcohol, aldehyde, ketone, carboxylic acid, ester (including triglycerides), acyl chloride, and amide. Structure includes functional groups and isomerism (constitutional isomers and stereoisomers). Reactivity of organic compounds is limited to: Substitution reactions using the following reagents: concentrated HCl, HBr, SOCl 2, NaOH, KOH (in alcohol or aqueous solution), concentrated NH 3, primary amines, primary alcohols/h+, H 2 O/H+, H 2 O/OH (Substitution reactions include esterification, condensation, hydrolysis, and polymerisation.) Oxidation reactions using the following reagents: MnO 4 /H +, Cr 2 O 7 2 /H +, Fehling s and Benedict s. Reduction of aldehydes and ketones with NaBH 4 Elimination reactions using the following reagents: KOH in alcohol and concentrated H 2 SO 4 (includes major and minor products from asymmetric alcohols and haloalkanes) Polymerisation reactions involving formation of polyesters and polyamides including proteins Addition reactions of alkenes (used for the identification of the products of elimination reactions), H 2 O/H + Physical properties of organic compounds may be used to distinguish between organic compounds and are limited to: Solubility Melting point and boiling point Rotation of plane-polarised light.

Wahanga 4 Te Kaupapa: Exam Revision About 2 weeks In this module ākonga will revise for the external achievement standard examinations. A week will be used to review each of the standards and one week will be used for exam question practice.
