Science and Technology Units

Unit 1: Understanding Life Systems - Interactions in the Environment (Term 1)

Humans have many impacts on the environment. In this unit, you will analyse some of these impacts and their consequences, while reflecting upon your personal responsibility to protect the environment. You will observe and investigate  existing ecosystems and investigate factors that may affect balances within the system. You will learn that ecosystems consist of communities of plants and animals that are dependent on each other as well as on the non-living parts of the environment. 

Unit 2: Understanding Matter and Energy - Pure Substances and Mixtures (Term 1)

By exploring the distinction between pure substances, mixtures and solutions, you will come to recognize that most matter is either a solution or a mixture – including most foods and drinks and many medicines, cosmetics, building materials, and cleaning agents. You will use this information to weigh the social and environmental consequences of the use of various consumer products. 

Unit 3: Understanding Earth and Space Systems - Heat in the Environment (Term 2)

Heat energy plays a critical role in natural processes and in human life. Global warming has also focused considerable attention on the processes that control temperatures at the earth’s surface. By acquiring a working understanding of the nature of heat, you will gain new insights into the ways that heat affects our world. You will learn about the causes and effects of heat, investigate its properties, relate it to geological and meteorological processes, and design a device to minimize heat transfer. You will also use the particle theory to help  explain your observations. 

Unit 4: Understanding Structures and Mechanisms - Form and Function (Term 2)

Humans build structures to meet specific needs. In doing so, they must consider many factors, including not only the functions that the structures must perform, but also the resources available to build them, the intended lifetime of the structures, and the impact of the structures on the environment. You will learn about the effects of forces that act on and within different structural forms. You will investigate how different structural forms support or withstand loads by designing, building, and testing structures, using increasingly sophisticated techniques. Other factors that affect a structure’s functioning, such as type of structure and centre of gravity, will also be explored.
