Science Extension is a Year 12-only HSC subject offered in NSW, designed for high-achieving students who want to engage with the philosophy of science, conduct original scientific investigations, and refine advanced research and communication skills. It is a highly academic, research-oriented subject ideal for students pursuing STEM pathways. Modedu offers expert-led, 1:1 tutoring to support students through the challenging elements of Science Extension, from designing an investigation to producing a scholarly research report and preparing for the HSC exam.
Expert guidance for complex concepts
Science Extension is distinct from other HSC science subjects because it requires:
Understanding the nature, limitations, and evolution of science
Applying methodologies across Biology, Chemistry, Earth & Environmental Science, or Physics
Designing and conducting an original scientific investigation
Critically evaluating scientific literature
Students often need help with:
Framing a research question and hypothesis
Data collection methods, ethics, and risk assessment
Scientific writing, referencing, and peer-reviewed structure
Analysing results and addressing validity, reliability, and implications
