Chemistry Level 3
L3CHE Course DescriptionTeacher in Charge: Mrs K. Jom.
Recommended Prior LearningAchievement of 16 credits from Level 2 Chemistry (including AS91164 and AS91165) is recommended.
Helpful Accompanying Subjects:
• Physics
• Biology
• Mathematics
This course follows on from the NCEA Level 2 course and is designed to provide a suitable body of knowledge for students proceeding to tertiary level. The course re-examines the topics of Level 2 in much greater depth and provides an opportunity to discuss the impact of chemistry on the everyday world, especially as relates to New Zealand. Experimental work is done wherever possible to create a more mature understanding of the interplay between experiment and theory. Students intending to study Level 3 Chemistry should have studied Chemistry at the Level 2.
Topics covered are: Organic Chemistry, spectroscopic data, Aqueous Chemistry, Atomic Structure, Oxidation/Reduction, Inorganic Chemistry, Thermo-chemical principles
The following standards are the core standards that are available for study at this level. A standard course is made up of 20-21 credits.
AS 91388 Spectroscopic data - Internal worth 3Credits
AS 91390 Thermochemical principles - External worth 5 Credits
AS 91391 Organic chemistry - External worth 5 Credits
AS 91392 Aqueous systems - External worth 5 Credits
AS 91393 Oxidation-reduction - Internal worth 3 Credits
Note: for students pursuing Scholarship Chemistry, they will need to maintain a high achievement and understanding in all three externals as well as the Internal Assessments.
Course Overview
Term 1
AS 91393 Oxidation-reduction.
The study of this standard involves comparing and contrasting, and justifying, links between oxidation-reduction processes, observations, equations, and calculations. This requires the consistent use of chemistry vocabulary, symbols, and conventions.
AS 91391 Organic chemistry.
The study of this standard involves elaborating, justifying, relating, evaluating, or comparing and contrasting the links between the structure, functional groups, physical properties, and/or reactivity of organic compounds. This requires the consistent use of chemistry vocabulary, symbols, and conventions.
Term 2
AS 91392 Aqueous systems.
The study of this standard involves elaborating, justifying, relating, evaluating, comparing and contrasting, or analysing properties of aqueous systems in terms of equilibrium principles. This requires the consistent use of chemistry vocabulary, symbols, and conventions and may include related calculations.
Term 3
AS 91388 Spectroscopic data
Demonstrate understanding of spectroscopic data involves identifying discrete aspects of the structure of organic molecules and justifying the structure of organic molecules by using and integrating teacher provided spectroscopic data.
AS 91390 Thermochemical principles.
The study of this standard involves elaborating, justifying, relating, evaluating, comparing and contrasting, or analysing links between the properties of particles, the properties of substances they form, thermochemical principles, and related calculations. This requires the consistent use of chemistry vocabulary, symbols, and conventions.
Term 4
Revision to prepare for external examinations.
Assessment Information
The two internal standards will be completed in class under exam conditions. Student work will be moderated before entering their grades in Kamar. Further assessment opportunity is NOT offered for these standards. Resubmission will be offered for students who are close to achieve and the maximum grade will be "A".
The three external standards will be assessed in class, soon after completing each standard. All students are expected to sit for the preliminary exam during the last two weeks of term 3. These results are important for students for offering 'derived grades', in the case of missing NCEA exams due to unforeseen circumstances.
The external standards will be finally assessed during NCEA exam in November.
