Chemistry

Introduction

The fundamental essence of chemistry and the core component of the KS4 Chemistry Curriculum is the study of matter in terms of its structure, reactions, composition and properties. This matter is looked at through the lens of chemical analysis and the trope of atoms and atomic particles, including the way they are aligned and connected together. The KS4 chemistry subject-matter deals with the amalgamation, formulation, examination and characteristic attributes of materials and substances of various kinds. One of the core ideas of GCSE Chemistry is to assist students to acknowledge the accomplishments of the discipline in exhibiting the ways in which the complicated phenomenon of the man-made as well as the natural world can be explained vis-à-vis diverse prime concepts which are universally applicable.

Key Stage 4 curriculum History

KS4 is an integral part of the National Curriculum of England which has been introduced with the Education Reform Act. When the national curriculum was first introduced, legally, it was valid for both England and Wales. It was later that England alone was subjected to the British National Curriculum. The terminology pertaining to the stage has been specifically elucidated in the Education Act of 2002 as “the period beginning at the same time as the school year in which the majority of pupils in his class attain the age of fifteen and ending at the same time as the school year in which the majority of pupils in his class cease to be of compulsory school age.” It would be worthwhile to take note of the fact that the termination of compulsory education in England has been extended to encompass the period beyond the age of sixteen; however, compulsory education after the age of 16 is not deemed suitable for being categorized under Key Stage 4.

The objective of study

The primary motive of the KS4 Chemistry curriculum is to enhance the knowledge of key notions and concepts within the field of chemistry. The basis of GCSE Chemistry pertains to the furtherance of the idea of matter which is seen as the core component of analysis, while the arena of chemical analysis harps on atoms as well as elements which are held to exhibit periodic relationships in their physical and chemical attributes. The field of energy-changes chemistry visualizes the operation of atoms which may bind in dual ways by ceding electrons from one atom to another or through sharing of the same.

Students should be instructed about

The KS4 chemistry curriculum seeks to advance knowledge of the key concepts and ideas within the discipline of chemistry in order to develop a distinct vocabulary for the discipline in accordance with the tenets of GCSE Chemistry. Some of these prime principles are:

  • The forms of molecules in terms of its shape and the manner in which big structures are aligned is of huge significance in terms of the manner in which they behave
  • Reactions can take place when molecules clash with one another and do so at distinct rates as a result of dissimilarities in molecular collisions. Such chemical analysis is one of the core subject matter within the GCSE Chemistry curriculum
  • Chemical reactions occur in three distinct manners:
    • Electron transfer
    • Proton transfer
    • Electron sharing
  • Energy is preserved in chemical reactions and hence can neither be generated nor destroyed. The energy-changes chemistry seeks to establish that elemental principle

Accordingly the KS4 Chemistry program of study is elaborated to lay emphasis on relevant notions and concepts. These include:

  • Atomic Structure and the Periodic Table
  • Structure, bonding and the properties of matter
  • Chemical analysis and changes
  • Energy-changes chemistry
  • Rate and extent of chemical change
  • Chemical analysis
  • Chemical and allied industries
  • Earth and atmospheric science

Target group

Key Stage 4 follows Key Stage 3 and encases two years of school teaching in maintained schools in Wales and England. It encases year 10 and year 11, with the age of students ranging from 14 to 16.

Overview

Since the core subject-matter of the discipline is the consideration of molecules and atoms which form all matter, analysis of the same is indispensable for a proper understanding of the world around us. The KS4 chemistry curriculum is strategically laid out to provide an unflinching grasp over the discipline in the most intricate manner. Explication of the Energy changes chemistry and chemical analysis form the two most crucial activities within the discipline.
