- (a) General requirements. Students shall be awarded one credit for successful completion of this course. Suggested prerequisite: one unit of high school science. This course is recommended for students in Grades 11 or 12.
(b) Introduction.
- (1) In Geology, Meteorology, Oceanography, students conduct field and laboratory investigations, use scientific methods during investigations, and make informed decisions using critical thinking and scientific problem solving. Students study a variety of topics that include: characteristics and conditions of the Earth; formation and history of the Earth; plate tectonics; origin and composition of minerals and rocks and the rock cycle; processes and products of weathering; natural energy resources; interactions in a watershed; characteristics of oceans; characteristics of the atmosphere; and the role of energy in weather and climate.
- (2) Science is a way of learning about the natural world. Students should know how science has built a vast body of changing and increasing knowledge described by physical, mathematical, and conceptual models, and also should know that science may not answer all questions.
- (3) A system is a collection of cycles, structures, and processes that interact. Students should understand a whole in terms of its components and how these components relate to each other and to the whole. All systems have basic properties that can be described in terms of space, time, energy, and matter. Change and constancy occur in systems and can be observed and measured as patterns. These patterns help to predict what will happen next and can change over time.
- (4) Investigations are used to learn about the natural world. Students should understand that certain types of questions can be answered by investigations, and that methods, models, and conclusions built from these investigations change as new observations are made. Models of objects and events are tools for understanding the natural world and can show how systems work. They have limitations and based on new discoveries are constantly being modified to more closely reflect the natural world.

- (C) analyze methods of tracking continental and oceanic plate movement.
(7) Science concepts. The student knows the origin and composition of minerals and rocks and the significance of the rock cycle. The student is expected to:
- (A) demonstrate the density, hardness, streak, and cleavage of particular minerals;
- (B) identify common minerals and describe their economic significance;
- (C) classify rocks according to how they are formed during a rock cycle; and
- (D) examine and describe conditions such as depth of formation, rate of cooling, and mineral composition that are factors in the formation of rock types.
(8) Science concepts. The student knows the processes and end products of weathering. The student is expected to:
- (A) distinguish chemical from mechanical weathering and identify the role of weathering agents such as wind, water, and gravity;
- (B) identify geologic formations that result from differing weathering processes; and
- (C) illustrate the role of weathering in soil formation.
(9) Science concepts. The student knows the role of natural energy resources. The student is expected to:
- (A) research and describe the origin of fossil fuels such as coal, oil, and natural gas;
- (B) analyze issues regarding the use of fossil fuels and other renewable, non-renewable, or alternative energy resources; and
- (C) analyze the significance and economic impact of the use of fossil fuels and alternative energy resources.
(10) Science concepts. The student knows the interactions that occur in a watershed. The student is expected to:
