Unit A: Mix and Flow of Matter (Science and Technology emphasis) Overview: The materials that we us~including natural and manufactured ones~often take the form of fluids. Fluids are composed primarily of liquids and gases, but may also include solids in variety of forms. In investigating fluids, students discover that many common household materials are aqueous solutions or suspensions in which the main component is water, and learn that such diverse substances as air and oil are fluids. Students learn that the properties of individual fluids are important to their use, including such properties as density, buoyancy and viscosity of the fluid and its response to changes in temperature and pressure. The particle model of matter is introduced to help students maa:e a conceptual link between the nature of matter and the specific behaviour of fluids.
Focusing Questions: What are fluids: what are they made of and how do we use them?
What properties of fluids, and what interaction between fluids and other materials, are important to their use?

STS and Knowledge Outcomes Students will... Investigate and describe fluids used in technological devices and everyday materials
Students will... Investigate and describe the composition of fluids, and interpret the behavior of materials in solution
Students will... Investigate and compare the properties of gases and liquids and relate variations in their viscosity, density, buoyancy and compressibility to the particle model of matter
Students will... Identity, interpret and apply technologies based on properties of fluids |
