Term 2: Chemistry
Text: Oxford Science 8
Chemical Science Content Descriptions
• Properties of the different states of matter can be explained in terms of the motion and arrangement of particles (ACSSU151)
• explaining why a model for the structure of matter is needed
• modelling the arrangement of particles in solids, liquids and gases
using the particle model to explain observed phenomena linking the energy of particles to temperature changes
Differences between elements, compounds and mixtures can be described at a particle level (ACSSU152)
• modelling the arrangement of particles in elements and compounds
• recognising that elements and simple compounds can be represented by symbols and formulas
• locating elements on the periodic table
Chemical change involves substances reacting to form new substances (ACSSU225)
• identifying the differences between chemical and physical changes
• identifying evidence that a chemical change has taken place
• investigating simple reactions such as combining elements to make a compound
• recognising that the chemical properties of a substance, for example its flammability and ability to corrode, will affect its use
