Year 8 Science Course 2 2017 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 Wk 1 2 3 4 Topic Safety Rules Lab Equipment Changes of State: 5.1 Changes of State: 5.2 Atoms - Particle model to explain matter: 4.34.4 Content Review rules of Science Lab Drawing and naming scientific equipment Physical change – a change in shape or appearance Reversible changes Changing state Vaporisation/condensation Melting/solidification Sublimation Chemical Change - Model the arrangement of particles in solids, liquids and gases Changing shape of form Expansion and contraction Changes of state Comparing chemical change/physical change Atomic theory All matter composed of atoms Electron shells Explain atomic and mass numbers, relating to protons, neutrons and electrons Activities Resources and Experiments OS8, p2-3 questions 1-7.
