S3 CFE Chemistry

Overview

Each learner who chooses Combined Science will attend Chemistry for 2 periods a week.

Each learner who chooses Intro to Chemistry will attend Chemistry for 3 periods a week.

 

The course is aimed at parts of the first two Units of the N3/N4/N5 courses, called Chemical Changes & Structure and Nature's Chemistry.

Our Aim is two-fold: to provide Learners with the opportunity to sample Chemistry to see if it is a subject that interests them, and to measure their aptitude so that, together, we can make informed decisions about the most appropriate route for Progression.

It is unlikely that we will have time to cover everything so we will select parts from the following:

  • Chemical reactions and physical changed
  • Rates of Reaction
  • Solubility
  • Elements and the periodic table
  • Atoms to compounds
  • Atomic structure and bonding
  • Conservation of mass, chemical formulae and balanced equations
  • Fossil Fuels
  • Hydrocarbons
  • Practical lab skills

In addition, learners will be expected to become familiar with the following techniques:

  • filtration
  • evaporation
  • use of a balance
  • methods for the testing of gases
  • chromatography
  • distillation
  • methods for following rates of reactions
  • titrations

Learners should also be able to process experimental results by:

  • drawing diagrams of apparatus
  • using tables to present data
  • calculation of averages for experimental results
  • drawing graphs
  • calculating reaction rates

Learners should also develop their Investigative Skills in Chemistry, in particular, how to Evaluate their Experimental Procedures:

  • Repeating for Reliability
  • Using most Appropriate Apparatus for Accuracy 

 

Assessment

Assessment is important and one use of assessment is to help identify which courses would be the most suitable for individual learners to progress to the following year. We, therefore, have mini tests, unit tests and a formal S3 Exam (taken in April/May) and we would expect learners intending to progress to N5 to meet a minimum standard and, ideally, exceed this level so they can progress with confidence.

Professional judgement will also be used where we will also take into consideration the level of interest, application and involvement in lessons as well as attitude to homework and study.
