Science still life with a beaker and test tubes, a battery-and-bulb circuit, a microscope, a leaf specimen, a graduated cylinder and a dropper.

Build scientific concepts through observation, experiments, data, models and cross-topic application.

  • Turn everyday intuition into scientific explanations supported by evidence
  • Build complete enquiry from question, hypothesis and variables to conclusion
  • Connect ideas across biology, chemistry, physics, Earth and environmental science
  • Improve school assessment through graphs, models and practical records

Course highlights

Scientific thinking Separate evidence, inference and explanation Describe observations and data accurately before using scientific concepts to propose a testable explanation.
Observation and inference
Distinguish direct measurement, evidence-based inference and an untested hypothesis.
Use models
Apply particle, system, energy and interaction models to invisible processes.
Evaluate evidence
Judge sufficiency and reliability and recognise anomalies and limitations.
 Scientific enquiry Connect every practical step to the enquiry question Understand how procedures control variables, produce measurements and support or reject a hypothesis.
Question and hypothesis
Turn a phenomenon into a testable question and justified prediction.
Variables and fair tests
Define independent, dependent and controlled variables, controls and repeats.
Conclusion and improvement
Conclude from data, explain limitations and propose direct design improvements.
 Cross-topic understanding Connect science through common organising ideas Use matter, energy, systems, structure and function to understand relationships across units.
Life and environment
Connect life processes, health, heredity, ecosystems and environmental impact.
Matter and energy
Use particles, chemical change and energy transfer to explain material phenomena.
Force, electricity, waves and Earth
Use models for motion, circuits, waves, Earth and space.
 Data and assessment Communicate results through graphs and scientific language Organise records, calculations, visuals and explanations into evidence-based scientific answers.
Tables and graphs
Handle titles, units, axes, scales and trends accurately.
Calculation and units
Organise formulae, substitution, significant figures and plausibility.
Scientific explanation
Use precise terms and causal relationships rather than restating the observation.
