Science: Stage 4

Year 7: Being their first year in a science laboratory, they get the chance to experience what scientists do and study as well as learn about working with the laboratory equipment as they learn the basics of science including the scientific method, scientific reporting, biology, chemistry, physics and Earth science. Topics include:

  • Change
    Change is constantly happening around us and within us. Students will learn about change within the world around us and to our own bodies. Matter and the physical changes and energy changes that occur are explored through the water cycle. Changes to the Earth's surface are explored through the investigation of Australian landforms and the rock cycle. Changes to living things are explored through the context of growth, repair and reproduction.
  • Patterns
    Patterns are found throughout nature and form the basis of the models we used to make sense of the world we live in. Patterns include living and non-living classification, cells and the cause and effect of patterns.
  • Sustainability
    We as humans need and use resources for every part of our lives, from the cereal you had for breakfast, to the petrol that powers your car, to the trees that make up the page you are reading. Exploiting resources is at the very basis of life, but as populations increase and technology advances, our consumption of these resources is drastically snowballing. Thus it is imperative that we use resources sustainably and responsibly.
  • Skateboards
    We experience forces every second of every day. Knowing and understanding these forces allows us to use them to our advantage and create technologies that bring great benefit to our lives, as well as some fun.



Year 8: Having the basic understanding of science, students use their prior knowledge to apply and deepen their understanding to a new level, using it in real word situations. Topics include:

  • Life Bubble
    The human race has finally gone and ruined the Earth's climate. Areas that once produced food are now barren. Small islands and low lying coastal areas are under water. Billions of people are starving and without homes. What can we do? Can we find a new place to live in our solar system?
  • Energy Around You
    As a roller-coaster speeds downwards, the wheels of the rolling cart heat up. As a passenger, you feel the wind rushing past you, your hair flies around and you probably scream! Energy is needed to make all these things happen. Energy exists in many different forms, from electrical energy to sound, light and heat energy. Energy can change forms, but it is never lost.
  • Science Through Time
    Planet Earth is 4.5 billion years old. The events of the Earth's history are recorded in our rocks. From about 570 million years ago, the ancestors of plants and animals that now populate the Earth came into being. The remains of some of these life forms are captured in the rocks as fossils.

    After dinosaurs, came humans. From the Stone Age to the Modern Age, we have used elements and compounds to help us in everyday life including tools and weapons. Through new technologies and developments, we have been able to create completely new materials, enhancing and improve our daily lives.

  • Water World
    One natural resource that sets the planet Earth apart from most other planets is water. Only a certain amount of water exists on Earth. This essential natural resource is recycled again and again in the water cycle. Understanding the water cycle has affected the way we store and manage water in factories, on farms and in our homes. There is no shortage of seawater on the Earth, but you might be surprised how little fresh drinkable water exists.

    The everyday use of water depends upon its purity. Purity comes about by adopting various separation techniques. This producing quality water fit for consumption with limited bacterial/microorganism.
