About science

Science has developed as a field of intellectual activities as people have sought to discern and explain patterns of events and phenomena in the world around them. It has progressively developed into a learning discipline with its own customs, procedures and fields of investigation.

Science has accumulated a body of knowledge that leads to explanations for a variety of phenomena and interactions in our surroundings. Science investigates phenomena over a range of scales from the subatomic to the cosmological, from events that take place almost instantaneously to processes that occur over millions of years, from the origins of the universe to contemporary phenomena and it extrapolates to future events.

The Science faculty at Sefton High School attempts to provide students with a contemporary and coherent science education so that they may better understand the natural and technological world in which they live and make a positive contribution to the decisions that shape it.

Science courses

A variety of challenging and stimulating topics are studied in Years 7 to 10 with an emphasis on practical work, the integration of technology and student research. Each topic is approximately 5 weeks in duration and is designed to allow students to achieve their potential.

Year 7 science

The topics studied are:

  • Introduction to Science – Working Scientifically
  • Mixtures and Separation
  • Solar System
  • Forces
  • Classification
  • States of Matter
  • Rocks and Earth
  • Ecosystems
  • Fields

Year 8 science

The topics studied are:

  • Elements and Compounds
  • Chemical Changes
  • Cells and Plants
  • Multi-cellular Organisms
  • Human Impact on the Environment
  • Science and People’s Understanding of the World
  • Energy Transformations and Energy Efficiency
  • Earth’s Resources and Management

Year 9 science

The topics studied are:

  • Scientific research and health
  • Motion of Objects
  • Periodic Table
  • Plate Tectonics
  • Chemical Reactivity
  • Conservation of ecosystems
  • Energy Conservation
  • Exploring the Universe

Year 10 science

The topics studied are:

  • Properties of waves
  • Rates of Reactions
  • Scientific Technologies – DNA and Genetics
  • Natural Events
  • Electricity Generation
  • Evolution and Natural Selection
  • Radioactivity
  • Project based learning in Science – Working Scientifically

Each year group has an excursion or incursion organised to enhance their learning of the concepts being taught. In previous years, some excursions students attended include:

Year 7 – Taronga Zoo

Year 8 – Science Centre and Planetarium

Year 9 – Australian National Museum

Year 10 – Forensic Science (incursion), ANSTO

Assessment of science subjects

In Years 7 and 8 students are assessed through Mid Year and End of Year examinations which are structured in such a way as to allow students to achieve at their own level.

The examinations are attempted by all students.

In addition to this, students are assessed through specific topic Research Projects, Open-Ended Student Research Projects (in Year 8), written and oral reports and skills and knowledge tests.

In Years 7 and 10 students are assessed through Mid Year and End of Year examinations. Students also participate in a practical examination and an Open-Ended Student Research Project (in Year 10) that allows assessment of skills development.

In Year 11 assessment is carried out by an End of Course Examination as well as through a researach task, Depth Studies investigation and a field trip. These assessment tasks allow the students of Sefton High School to develop knowledge and understanding and skills of outcomes outlined in learning across the curriculum in their courses.

In Year 12 assessment is carried out by Mid Course and End Of Course Examinations as well as through field trip reports, research tasks, Open Ended Investigation/Practical Examination.

These assessment tasks allow the students of Sefton High School  to develop knowledge and understanding of the Prescribed Focus Areas of their courses as well as develop positive values about and attitudes towards themselves, others and learning as a lifelong process.

Science resources at our school

Sefton High School has six well-equipped laboratories with one dedicated computer room to facilitate the integration of technology into the classroom. There are also data-loggers and digital microscopes for microscopic observations.

Co-curricular activities for science

In addition to their regular studies, students at Sefton High School are encouraged to participate in co-curricular activities to broaden their scientific knowledge and skills. These include:

  • The Australian Schools Science Competition
  • The National Chemistry Quiz
  • The Rio Tinto Australian Science Olympiad
  • The NSW Schools Titration Competition
  • National Science Week Activities
