Year 9 Science

To enable students to:

• build confidence and curiosity in science through hands-on investigations and evidence-based explanations
• understand that matter is made of particles and recognise how elements, compounds, mixtures, and the periodic table help explain real-world materials
• describe how chemical reactions occur, recognise signs of change, and communicate these changes using word equations
• apply particle, chemical, and physical science ideas to situations in their lives (e.g., fuels, energy, waves, motion)
• explain how energy is transferred or transformed in systems such as engines, circuits, and ecosystems
• investigate waves (sound, light), describing how they behave and how they transfer energy without moving matter
• explore forces and motion using Newton’s laws, predict motion changes, and represent forces with diagrams
• understand Earth systems (atmosphere, hydrosphere, biosphere, lithosphere) and how matter and energy cycle between them
• recognise how carbon moves through Earth’s spheres and describe the impact of human activity on climate
• explain how DNA, genes, proteins, and environment contribute to traits and variation in organisms
• investigate infectious and non-infectious diseases, immunity, and strategies for preventing disease
• describe how plants and animals transport essential substances and how diffusion, osmosis, and active transport support life
• develop scientific thinking by collecting data, interpreting patterns, using models, and drawing evidence-based conclusions

Year 9 students study the following topic areas:

• Matter: elements, molecules, compounds, mixtures
• Periodic Table: metals/non-metals, groups & periods
• Chemical Reactions: acids, bases, metals, carbonates
• Combustion & Energy: fuels, heat transfer
• Waves: sound, light, basic wave properties
• Motion & Forces: Newton’s laws, friction
• Earth Systems: spheres of the Earth, water & carbon cycle
• Ecosystems: interactions, nutrient cycles, human impacts
• Genetics: DNA, genes, proteins, variation
• Disease & Immunity: pathogens, immune responses
• Body Systems: circulatory system, plant transport
