Year 9 homeschool curriculum
In Year 9, learners use Pythagoras' theorem to find unknown lengths in right-angled triangles and connect algebra with graphs by working with gradient and the equation of a straight line. They expand binomial products, work with very large and very small numbers in scientific notation, and apply similarity and scale. Statistics and probability extend to comparing distributions and two-step chance experiments.

In Year 9, learners write sustained analytical essays with a clear thesis and well-developed body paragraphs. They analyse poetry closely, considering imagery, structure and tone together, and they become critical consumers of media, identifying bias, framing and omission. Their own writing increasingly uses grammar and vocabulary deliberately for effect.
In Year 9, students investigate how the nervous and endocrine systems help the body respond to change, and how matter and energy flow through ecosystems. They explore atomic structure, investigate acids and bases, explain Earth's features using plate tectonics and analyse how heat is transferred by conduction, convection and radiation. They collect and analyse data with attention to accuracy and repeated trials.
In Year 9, learners study the making of the modern world from about 1750 to 1918. They investigate the Industrial Revolution, the movement of peoples, imperialism and its effects, the making of the Australian nation including frontier conflict, and Australia's experience of World War I, while building skills in analysing sources and constructing arguments.
In Year 9, learners study biomes and food security and the geographies of interconnections. They examine the world's biomes, how people have altered them to produce food, and the challenges of feeding a growing population sustainably. They also investigate how people are connected to places through trade, travel, technology and production, and the consequences of these connections.
