· Chemical Reactions

· Inquiry question: What are the products of a chemical reaction?

· Students:

· investigate a variety of reactions to identify possible indicators of a chemical change

· use modelling to demonstrate

· the rearrangement of atoms to form new substances 

· the conservation of atoms in a chemical reaction (ACSCH042, ACSCH080)

· conduct investigations to predict and identify the products of a range of reactions, for example:

· synthesis

· decomposition

· combustion

· precipitation

· acid/base reactions

· acid/carbonate reactions (ACSCH042, ACSCH080)

· investigate the chemical processes that occur when Aboriginal and Torres Strait Islander Peoples detoxify poisonous food items 

· construct balanced equations to represent chemical reactions 

· Predicting Reactions of Metals

· Inquiry question: How is the reactivity of various metals predicted?

· Students:

· conduct practical investigations to compare the reactivity of a variety of metals in:

· water

· dilute acid 

· oxygen

· other metal ions in solution

· construct a metal activity series using the data obtained from practical investigations and compare this series with that obtained from standard secondary-sourced information

· analyse patterns in metal activity on the periodic table and explain why they correlate with, for example:

· ionisation energy 

· atomic radius 

· electronegativity 

· apply the definitions of oxidation and reduction in terms of electron transfer and oxidation numbers to a range of reduction and oxidation (redox) reactions

· conduct investigations to measure and compare the reduction potential of galvanic half-cells 

· construct relevant half-equations and balanced overall equations to represent a range of redox reactions

· predict the reaction of metals in solutions using the table of standard reduction potentials

· predict the spontaneity of redox reactions using the value of cell potentials (ACSCH079, ACSCH080)

· Rates of Reactions

· Inquiry question: What affects the rate of a chemical reaction?

· Students:

· conduct a practical investigation, using appropriate tools (including digital technologies), to collect data, analyse and report on how the rate of a chemical reaction can be affected by a range of factors, including but not limited to: 

· temperature

· surface area of reactant(s)

· concentration of reactant(s)

· catalysts

· investigate the role of activation energy, collisions and molecular orientation in collision theory

· explain a change in reaction rate using collision theory
