Course Content
Mechanical Systems. Machines are tools that help humans to transfer energy into motion and move materials in a controlled way. Students will learn about complex machines and come to an understanding that components are linked so that energy is transferred efficiently and desired functions can be performed. By comparing technologies over time, students will recognize that different approaches have been adapted to meet common needs.

Light and Optical Systems. Optical devices that improve and extend our vision aid our understanding of the world around us. In learning about light and its properties, students investigate interactions with different materials and interpret its behaviour. Students will then use their understanding of light to interpret light-based technologies and predict new technologies that may be used in our future.

Cells and Systems. Living things share certain characteristics and have specific structures to perform functions. Life can be interpreted at a variety of levels, from individual cells to complex organisms. Students will investigate ways that components of a living system work together and learn that healthy organisms function as balanced systems within a life-supporting environment.
|
Fresh and Saltwater Systems. This unit has a social and environmental emphasis. Over two-thirds of the Earth’s surface is covered by fresh and saltwater, and as humans we rely heavily on these systems. Students will explore aquatic systems and come to understand the interaction of landforms, sediments water and climate. Also, students will investigate factors that affect living things in aquatic environments and come to understand how environments are affected by human activity.
