Chemistry

Chemistry is the study of materials and substances, and the transformations they undergo through interactions and the transfer of energy. Chemistry develops students' understanding of the key chemical concepts and models of structure, bonding, and chemical change, including the role of chemical, electrical and thermal energy. Students learn how models of structure and bonding enable chemists to predict properties and reactions and to adapt these for particular purposes.

An understanding of chemistry is relevant to a range of careers, including those in forensic science, environmental science, engineering, medicine, pharmacy and sports science. Additionally, chemistry knowledge is valuable in occupations that rely on an understanding of materials and their interactions, such as art, winemaking, agriculture and food technology.


  

Year 8 Chemistry

  • The properties of the different states of matter can be explained in terms of the motion and arrangement of particles.
  • Differences between elements, compounds and mixtures can be described at a particle level.
  • Chemical change involves substances reacting to form new substances.


  

Year 9 Chemistry

All matter is made of atoms that are composed of protons, neutrons and electrons; natural radioactivity arises from the decay of nuclei in atoms.

  • Describing the formation of ions and structure of the ionic bond.
  • Chemical reactions involve rearranging atoms to form new substances; during a chemical reaction mass is neither created nor destroyed.
  • Chemical reactions, including combustion and the reactions of acids, are important in both non-living and living systems and involve energy transfer.
  • Identifying reactants and products in chemical reactions and modelling chemical reactions in terms of rearrangement of atoms.
  • Describing observed reactions using word equations, and recognising that the conservation of mass in a chemical reaction can be demonstrated by simple chemical equations.

Year 10 Chemistry

  • Types of bonding, patterns of interactions with other materials, properties and structures.
  • Research the properties of the periodic table and its development and refinement over time.
  • Relate electronic configuration to the formation of compounds.
  • Investigate chemical reactions and represent them using word and balanced symbol equations.
  • Explore how rates of everyday chemical processes are increased or decreased.
  • Activity series of metals with water, steam and dilute acids
