Grade 8 Science Unit Plan Unit A - Mix and Flow of Matter (Science and Technology Emphasis) Grade 8 Unit Overview (Alberta) The materials that we use, 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 a 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 make a conceptual link between the nature of matter and the specific behaviour of fluids.
