The student is expected to: (A) identify sources and determine the amounts of water in a watershed, including rainfall, groundwater, and surface water; (B) identify factors that contribute to how water flows through a watershed; and (C) identify water quantity and quality in a local watershed. The student knows that geological phenomena and fluid dynamics affect aquatic systems.The student is expected to: (A) demonstrate basic principles of fluid dynamics, including hydrostatic pressure, density, salinity, and buoyancy; (B) identify interrelationships between ocean currents, climates, and geologic features; and (C) describe and explain fluid dynamics in an upwelling and lake turnover. The student knows the types and components of aquatic ecosystems.
Students should be able to distinguish between scientific decision-making methods and ethical and social decisions that involve the application of scientific information. A system is a collection of cycles, structures, and processes that interact.The student is expected to: (A) differentiate among freshwater, brackish, and saltwater ecosystems; (B) identify the major properties and components of different marine and freshwater life zones; and (C) identify biological, chemical, geological, and physical components of an aquatic life zone as they relate to the organisms in it. The student knows environmental adaptations of aquatic organisms.The student is expected to: (A) classify different aquatic organisms using tools such as dichotomous keys; (B) compare and describe how adaptations allow an organism to exist within an aquatic environment; and (C) compare differences in adaptations of aquatic organisms to fresh water and marine environments. The student knows about the interdependence and interactions that occur in aquatic environments.Required prerequisite: one unit of high school Biology.
Suggested prerequisite: Chemistry or concurrent enrollment in Chemistry. In Aquatic Science, students study the interactions of biotic and abiotic components in aquatic environments, including impacts on aquatic systems.
Students should analyze a system in terms of its components and how these components relate to each other, to the whole, and to the external environment. The student is expected to: (A) demonstrate safe practices during laboratory and field investigations; and (B) demonstrate an understanding of the use and conservation of resources and the proper disposal or recycling of materials. The student uses scientific methods during laboratory and field investigations.
