Triple Award Science, commonly referred to as Triple Science, results in three separate GCSEs in Biology, Chemistry and Physics and provide the broadest coverage of the main three science subjects. The qualifications are offered by the five main awarding bodies in England; AQA , Edexcel , OCR , CIE and Eduqas .
The tiering of qualifications allows a subset of grades to be reached in a specific tier's paper. Formerly many subjects were tiered, but with the mid-2010s reform the number of tiered subjects reduced dramatically, including the removal of tiering from the GCSE English specifications. Untiered papers allow any grade to be achieved.
A concise four-page summary of the most important material in the Green Book was published in the July–August 2011 issue of Chemistry International, the IUPAC news magazine. The second edition of the Green Book (ISBN 0-632-03583-8) was first published in 1993. It was reprinted in 1995, 1996, and 1998.
Edexcel (also known since 2013 as Pearson Edexcel) [2] is a British multinational education and examination body formed in 1996 and wholly owned by Pearson plc since 2005. It is the only privately owned examination board in the United Kingdom. [3] Its name is a portmanteau term combining the words education and excellence.
The UK's examination boards sometimes work together. For example, they sometimes offer qualifications jointly or share training materials for common parts of specifications. The JCQ (Joint Council for Qualifications) is a common voice for UK exam boards. The JCQ is made up of AQA, CCEA, City & Guilds, Edexcel, OCR, SQA and WJEC.
Following the changes to GCSEs, only one route is available to the student that takes Edexcel or Eduqas combined science. [31] [36] In Edexcel's combined science specification document the curriculum is delivered in the three traditional disciplines of biology, chemistry and physics, but in Eduqas's , the science curriculum is divided into four ...
Chemical classification systems attempt to classify elements or compounds according to certain chemical functional or structural properties. Whereas the structural properties are largely intrinsic, functional properties and the derived classifications depend to a certain degree on the type of chemical interaction partners on which the function is exerted.
Skeletal structural formula of Vitamin B 12. Many organic molecules are too complicated to be specified by a molecular formula. The structural formula of a chemical compound is a graphic representation of the molecular structure (determined by structural chemistry methods), showing how the atoms are connected to one another.
