Year 9 science
In Year 8, students learn that cells are the basic units of living things and that cells form tissues, organs and body systems. They use the particle model to explain states of matter, distinguish elements, compounds and mixtures, and tell physical changes from chemical changes. They explore the rock cycle and investigate how energy is transferred and transformed.

Biological sciences
- Cells: the building blocks of lifeTopic outlineStudents compare plant and animal cells, identify structures such as the nucleus, cell membrane, cell wall and chloroplasts, and learn how microscopes revealed cells.
- Body systems working togetherTopic outlineStudents explore how the digestive, circulatory and respiratory systems work together to supply cells with nutrients and oxygen and remove wastes.
Chemical sciences
- The particle model of matterFull lesson · 60 minStudents use the idea that all matter is made of tiny moving particles to explain the properties of solids, liquids and gases, diffusion and expansion.
- Elements, compounds and mixturesTopic outlineStudents distinguish elements, compounds and mixtures using particle diagrams and simple chemical formulas such as H2O and CO2.
- Physical and chemical changeFull lesson · 60 minStudents identify evidence of chemical change, such as gas production, colour change and temperature change, and compare it with physical change.
