Mix and Flow of Matter
The materials that we use—including natural and manufactured ones—often take the form of fluids. Students learn that such diverse substances as air, natural gas, water and oil are fluids. In further investigations, they discover that many common household materials are aqueous solutions or suspensions in which the main component is water. Students learn that the properties of individual fluids are important to their use, including such properties as density, buoyancy, viscosity and the fluid’s response to changes in temperature and pressure. The particle model of matter is introduced to help students make a conceptual link between the nature of matter and the specific behaviour of fluids.
Matter on the Move
Students explore the particle model of matter in regards to solids, liquids, and gases.
Mixing and Dissolving
Students explore homogeneous and heterogeneous mixtures, solutes and solvents.
Separating Earth's Mixtures
Students explore different methods to separate mixtures.
Flow Rate and Viscosity
Students explore viscosity and rate of flow of fluids.
Students explore density in it relation to mass and volume.
Students explore buoyancy and its relationship to density.
Students explore how pressure affects flow of fluids.
Students explore hydraulic and pneumatic systems.
Cells and Systems
Living things take a variety of forms as reflected in their structures, internal processes and ways of responding to their environments. Finding pattern within this diversity has been a major challenge for the biological sciences and has led to the development of ideas, such as systems, cells, structures and functions—ideas developed from the study of all living things. Using these ideas, students learn to interpret life at a variety of levels, from individual cells to complex organisms. To develop their understanding, students investigate ways that components of a living system work together and, through these studies, learn that healthy organisms—including healthy humans—function as balanced systems within a life-supporting environment.
Light and Optical Systems
Our understanding of the world is based largely on what we see—both directly, and aided by optical devices that improve and extend our vision. Such tools as the microscope and telescope have helped extend knowledge in a variety of science fields, from the study of cells and stars to studies of the nature of light itself. In learning about light, students investigate its interactions with different materials and interpret its behaviour using a geometric ray model. Students then use their understanding of light to interpret a variety of light-based technologies and envisage new technologies we may use in the future.
Machines are used for many purposes in our daily lives when we need to transfer energy into motion or move materials in a controlled way. In learning about mechanical devices, students investigate how components are linked so that energy is transferred efficiently and desired functions are performed. A comparison of past and present technologies helps students recognize that different approaches have been used over time to meet common needs. Evaluations of efficiency, effectiveness and impacts on daily life, the community and the environment are important considerations in this unit.
Freshwater and Saltwater Systems
Earth is sometimes described as the water planet: over two-thirds of Earth’s surface is covered by oceans and freshwater features. By exploring examples of aquatic systems, students come to appreciate the dynamic nature of these systems and learn about the interaction of landforms, sediments, water and climate. Students also investigate factors that affect the distribution and health of living things in aquatic environments and the supply and quality of water for human use.
