Chemistry 1.3 Demonstrate understanding of aspects of carbon chemistry
Science 1.6 Investigate the implications of the use of carbon compounds as fuels
This achievement standard involves demonstrating understanding of the structure, properties, production, uses, importance and effects of carbon compounds.
This achievement standard involves the implications of the use of carbon compounds as fuels. This includes the properties of carbon compounds and the importance and effects of their uses and combustion products on humans or the environment.
Achievement Demonstrate understanding involves describing, identifying, naming, drawing, giving an account of, defining aspects of carbon chemistry. This requires the use of chemistry vocabulary, symbols and conventions including names, formulae and completing word equations.
Merit Demonstrate detailed understanding requires making and explaining links between aspects of carbon chemistry. This requires explanations that use chemistry vocabulary, symbols and conventions including names, formulae and writing word equations or completing given symbol equations
Excellence Demonstrate comprehensive understanding will typically involve elaborating, justifying, relating, evaluating, comparing and contrasting, or analysing links between aspects of carbon chemistry. This requires the consistent use of chemistry vocabulary, symbols and conventions including writing balanced symbol equations.
Achievement Investigate will typically involve making and recording observations, processing, interpreting, identifying, classifying and describing selected properties of carbon compounds and implications of their use as fuels. Selected properties include melting point, boiling point and combustion reactions. This requires the use of chemistry vocabulary, symbols and conventions including names and structural formulae and writing word equations.
Merit Investigate in detail typically involves making links between selected properties of carbon compounds, their uses as fuels and the implications of their uses as fuels. This could include comparing physical properties and chemical properties of different carbon compounds, the use of different carbon compounds as fuels and the implications of the use of different carbon compounds as fuels. This requires explanations that use chemistry vocabulary, symbols and conventions including names and structural formulae and completing symbol equations.

Aspects of carbon chemistry will be selected from: ·Structure- structural formulae -names of carbon compounds using systematic nomenclature - covalent bonding between atoms. ·Properties- solubility in water - trends in melting and/or boiling points - complete and incomplete combustion reactions - polymerisation reactions of ethene and propene. ·Production- fractional distillation of crude oil - cracking of fractions - fermentation - methanol from natural gas . ·Uses and importance- fuels - polymers from ethene and propene. ·Effects of combustion products on human health and the environment.
Implications of the use of carbon compounds as fuels consider the importance and effects of their uses and combustion products on humans or the environment and could include: the efficiency of fuels, air or thermal pollution, effect on global climate, ocean acidification, use of non–renewable resources and / or food crops for fuels.
Carbon compounds are restricted to straight chain alkanes, ethene and propene, methanol and ethanol. Structures and names of alkanes are limited to those alkanes containing no more than 8 carbon atoms.
Carbon compounds will typically include alkanes and alcohols. Systematic names and structural formulae of carbon compounds are restricted to straight chain alkanes up to 8 carbon atoms, methanol and ethanol.
