(a) General requirements. Students shall be awarded one credit for successful completion of this course. Required prerequisite: one unit of high school Biology. Suggested prerequisite: Chemistry or concurrent enrollment in Chemistry. This course is recommended for students in Grades 10, 11, or 12.
(b) Introduction.
  (1) Aquatic Science. In Aquatic Science, students study the interactions of biotic and abiotic components in aquatic environments, including impacts on aquatic systems. Investigations and field work in this course may emphasize fresh water or marine aspects of aquatic science depending primarily upon the natural resources available for study near the school. Students who successfully complete Aquatic Science will acquire knowledge about a variety of aquatic systems, conduct investigations and observations of aquatic environments, work collaboratively with peers, and develop critical-thinking and problem-solving skills.
  (2) Nature of science. Science, as defined by the National Academy of Sciences, is the "use of evidence to construct testable explanations and predictions of natural phenomena, as well as the knowledge generated through this process." This vast body of changing and increasing knowledge is described by physical, mathematical, and conceptual models. Students should know that some questions are outside the realm of science because they deal with phenomena that are not scientifically testable.
  (3) Scientific inquiry. Scientific inquiry is the planned and deliberate investigation of the natural world. Scientific methods of investigation can be experimental, descriptive, or comparative. The method chosen should be appropriate to the question being asked.
  (4) Science and social ethics. Scientific decision making is a way of answering questions about the natural world. Students should be able to distinguish between scientific decision-making methods and ethical and social decisions that involve the application of scientific information.
  (5) Scientific systems. A system is a collection of cycles, structures, and processes that interact. All systems have basic properties that can be described in terms of space, time, energy, and matter. Change and constancy occur in systems as patterns and can be observed, measured, and modeled. These patterns help to make predictions that can be scientifically tested. 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.
(c) Knowledge and skills.
  (1) Scientific processes. The student, for at least 40% of instructional time, conducts laboratory and field investigations using safe, environmentally appropriate, and ethical practices. The student is expected to:
    (A) demonstrate safe practices during laboratory and field investigations, including chemical, electrical, and fire safety, and safe handling of live and preserved organisms; and
    (B) demonstrate an understanding of the use and conservation of resources and the proper disposal or recycling of materials.
  (2) Scientific processes. The student uses scientific methods during laboratory and field investigations. The student is expected to:
    (A) know the definition of science and understand that it has limitations, as specified in subsection (b)(2) of this section;
    (B) know that scientific hypotheses are tentative and testable statements that must be capable of being supported or not supported by observational evidence. Hypotheses of durable explanatory power which have been tested over a wide variety of conditions are incorporated into theories;
    (C) know that scientific theories are based on natural and physical phenomena and are capable of being tested by multiple independent researchers. Unlike hypotheses, scientific theories are well-established and highly-reliable explanations, but they may be subject to change as new areas of science and new technologies are developed;
    (D) distinguish between scientific hypotheses and scientific theories;
    (E) plan and implement investigative procedures, including asking questions, formulating testable hypotheses, and selecting, handling, and maintaining appropriate equipment and technology;
    (F) collect data individually or collaboratively, make measurements with precision and accuracy, record values using appropriate units, and calculate statistically relevant quantities to describe data, including mean, median, and range;
    (G) demonstrate the use of course apparatuses, equipment, techniques, and procedures;
    (H) organize, analyze, evaluate, build models, make inferences, and predict trends from data;
    (I) perform calculations using dimensional analysis, significant digits, and scientific notation; and
    (J) communicate valid conclusions using essential vocabulary and multiple modes of expression such as lab reports, labeled drawings, graphic organizers, journals, summaries, oral reports, and technology-based reports.
  (3) Scientific processes. The student uses critical thinking, scientific reasoning, and problem solving to make informed decisions within and outside the classroom. The student is expected to:
    (A) in all fields of science, analyze, evaluate, and critique scientific explanations by using empirical evidence, logical reasoning, and experimental and observational testing, including examining all sides of scientific evidence of those scientific explanations, so as to encourage critical thinking by the student;
    (B) communicate and apply scientific information extracted from various sources such as current events, news reports, published journal articles, and marketing materials;
    (C) draw inferences based on data related to promotional materials for products and services;
    (D) evaluate the impact of research and technology on scientific thought, society, and the environment;
    (E) describe the connection between aquatic science and future careers; and
    (F) research and describe the history of aquatic science and contributions of scientists.
  (4) Science concepts. Students know that aquatic environments are the product of Earth systems interactions. The student is expected to:
    (A) identify key features and characteristics of atmospheric, geological, hydrological, and biological systems as they relate to aquatic environments;
    (B) apply systems thinking to the examination of aquatic environments, including positive and negative feedback cycles; and
    (C) collect and evaluate global environmental data using technology such as maps, visualizations, satellite data, Global Positioning System (GPS), Geographic Information System (GIS), weather balloons, buoys, etc.
  (5) Science concepts. The student conducts long-term studies on local aquatic environments. Local natural environments are to be preferred over artificial or virtual environments. The student is expected to:
    (A) evaluate data over a period of time from an established aquatic environment documenting seasonal changes and the behavior of organisms;
    (B) collect baseline quantitative data, including pH, salinity, temperature, mineral content, nitrogen compounds, and turbidity from an aquatic environment;
    (C) analyze interrelationships among producers, consumers, and decomposers in a local aquatic ecosystem; and
    (D) identify the interdependence of organisms in an aquatic environment such as in a pond, river, lake, ocean, or aquifer and the biosphere.
  (6) Science concepts. The student knows the role of cycles in an aquatic environment. The student is expected to:
    (A) identify the role of carbon, nitrogen, water, and nutrient cycles in an aquatic environment, including upwellings and turnovers; and
    (B) examine the interrelationships between aquatic systems and climate and weather, including El Niño and La Niña, currents, and hurricanes.
  (7) Science concepts. The student knows the origin and use of water in a watershed. 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.
  (8) Science concepts. 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.
  (9) Science concepts. The student knows the types and components of aquatic ecosystems. The student is expected to:
