Level 2 Chemistry (L2CHE)

Overview

L2 Chemistry begins to investigate chemistry in much more detail than in previous years. L2 Chemistry is a prerequisite course for further study of Chemistry at L3 and for many Polytech and University courses.

What will I learn?

  • Practical investigation using quantitative analysis AS2.1 (4 weeks)

You will measure and compare of amounts of substances, leading to the solving of quantitative chemical problems. You will also determine the concentration of solutions by titration.

  • Practical investigation using qualitative analysis AS2.2 (4 weeks)

You will carry out precipitation reactions to identify unknown ions in solution.

  • Structure, bonding and energy changes AS2.4 (7 weeks)

An introduction to the theories developed in order to explain the structure of matter and how this determines the properties of substances.

  • Organic Compounds AS2.5 (5 weeks)

The properties of organic compounds: alkanes, alkenes, alkynes, haloalkanes, alcohols, carboxylic acids and amines.

  • Chemical reactivity AS2.6 (5 weeks)

This is an introduction to principles that effect chemical reactivity, equilibrium and acids and bases.

  • Oxidation-Reduction Reactions AS2.7 (4 weeks)

You will investigate reactions that are involved in corrosion, bleaches, extraction of metals, explosions and other important processes.

What should I have done already?

The minimum pre-requisites for entry to the L2 Chemistry course are 'Achieved' grades in:

L1 Science AS1.5 Acids & Bases

L1 Chemistry AS1.1 Chemistry investigation

L1 Maths AS1.2 Algebra

Assessment outline

L2CHE

Assessment regulations

There will be three internal assessments during the year. There WILL NOT be any reassessment opportunities offered.

The final examination in November assesses the three external standards.

It is vital that you read and understand the rules relating to NCEA in the Student Handbook. The following rules are emphasized here:

Late Work

Work submitted late for the internally assessed standards will not be marked.

If you have a genuine reason why you are unable to submit work by the due date or unable to take part in an assessment on the set day, then you are able to apply for an extension. This should occur prior to the due date/date of assessment, not after. Approach your subject teacher and make your case. Read the NCEA Student Handbook for more detail.

Authenticity and Appeals

These issues are dealt with by the college’s assessment procedures. Essentially all work must be your own. If you copy anything from the internet or a book, you must attribute the source of the work. Do not claim it as your own! You have the right to appeal a grade if you consider you have been treated unfairly. Read your NCEA Student Handbook for details.

Where does this course lead?

This course leads to L3 Chemistry where the minimum prerequisite for entry is 14 L2 Chemistry credits with 'Achieved' grades in at least two of the externally assessed Achievement Standards.
