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 the relationship of buoyancy and density in fluids.
Students explore how pressure affects flow of fluids.
In this lesson we will explore how hydraulic and pneumatic systems (or fluid systems) work, what principles they follow and how to construct such a system.
