Year 9 Biological Sciences

In this unit of Biology, students will learn about the various systems in the body that enable it to detect and respond appropriately to changes in its environment. This includes understanding what homeostasis is and how the nervous and endocrine systems work together to maintain optimal conditions in the body. The body’s immune system is also designed to detect and respond to changes to maintain the overall health of the body and students will learn what happens when the body’s defences breakdown and disease occurs. Students will also study ecosystem and the interconnectedness of all living things with each other and their abiotic environment. Students will investigate how matter cycles through ecosystems whereas energy flows through it and ultimately comes from the Sun.

Year 9 Chemical Sciences

In this Chemistry unit, students will learn about atomic structure and how in some cases, radioactivity is emitted from the decay of the nuclei of some atoms. Students will study various types of chemical reactions and begin to understand that reactions enable particles to rearrange themselves to produce new substances with new properties. Student will be able to predict possible reactants, based on their knowledge of products and will observe how some reactions produce energy in the form of heat, whereas others absorb heat energy. Students will build on their knowledge from previous years and begin to use correct scientific nomenclature, symbols and formulae to write scientific equations to represent reactions. Chemical reactions occur all around us and are critical to sustaining life through the processes of photosynthesis and cellular respiration.

Year 9 Earth & Space Sciences

Students will also investigate the different ways that tectonic plates move within the Earth’s crust and the effects these movements can have on geological activity. Students will learn about continental drift and the evidence to support this theory as well as investigate the other effects of plate movement including earthquakes and volcanic eruptions.

Year 9 Physics

This unit is designed to allow students to learn how heat us considered a form of energy and investigate various forms of heat transfer such as, conduction, convection and radiation. Students will be able to use their understandings to discuss how heat transfer can be prevented. In the second part of the programme, students will investigate electricity and how static and current electricity differ. Students will investigate current electricity in depth and design various circuits, including series and parallel and how voltage, current and resistance is affected in different circuits.
