What are the Key Science Skills VCAA expects?Show answer
VCAA shares Key Science Skills across all VCE sciences, contextualised for Chemistry:
What is choosing a Chemistry investigation?Show answer
A strong VCE Chemistry investigation:
What is sustainability framing?Show answer
VCAA's 2023-2027 design explicitly foregrounds sustainability. A Chemistry investigation that incorporates atom economy, green-chemistry principles, renewable feedstocks, or circular-economy framing is well-aligned with the AoS 3 contemporary-challenge requirement.
What is no connection to a contemporary challenge?Show answer
The VCAA framing requires this. An investigation that doesn't situate the question in a contemporary challenge fails one of the explicit Study Design requirements.
What is plagiarised secondary data?Show answer
Primary data is required. Using only published values is not an investigation.
What are generic "human error" limitations?Show answer
Specify the source (e.g. titration end-point uncertainty +/- 0.05 mL; balance precision +/- 0.001 g) and the propagated impact on the result.
What is q1?Show answer
Identify two of the four allowed focus areas for the Unit 4 AoS 3 investigation. [2 marks]
What is q2?Show answer
Explain why VCAA requires the investigation to be "inspired by a contemporary chemical challenge". [4 marks]
What is q3?Show answer
Design an outline investigation (research question, method overview, data analysis approach, contemporary challenge framing) on a topic of your choice. [8 marks]
