Convection
Learning targets for this unit:
CONTENT: • I will be able to describe density as the ratio of mass to its volume. • I will be able to predict that two fluids of equal volume but different in mass, the one with the greater mass is more dense. • I will be able to defend that as matter heats up, it expands, causing the matter to become less dense. • I will be able to conclude that convection is the circulation of fluid (liquid or gas) that results from energy transfer; relatively warm masses rise and relatively cool masses sink. |
PROCESS: • Compare salt solutions to determine their relative density. • Use mass and volume data to calculate densities (g/ml). • Explain density as a ratio between a mass and its volume. • Observe convection in liquid and gas environments. • Describe how materials of different densities interact. • Explain how energy transfer drives the process of convection. |
