§112.41. Skills for Science, High School.

The provisions of this written curriculum shall be implemented beginning September 1, 1997.


§112.42. Integrated Physics and Chemistry (one credit).

(a)  General requirements. Students shall be awarded one

     credit for successful completion of this course.

     Prerequisites: none. This course is recommended for

     students in Grades 9 or 10.



(b)  Introduction.



     (1)  In Integrated Physics and Chemistry, students

          conduct field and laboratory investigations, use

          scientific methods during investigations, and make

          informed decisions using critical-thinking and

          scientific problem-solving. This course integrates

          the disciplines of physics and chemistry in the

          following topics: motion, waves, energy

          transformations, properties of matter, changes in

          matter, and solution chemistry.

     

     (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.

§112.44. Environmental Systems (one credit).

(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 10, 11, or 12.



(b)  Introduction.



     (1)  In Environmental Systems, 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: biotic and abiotic factors in

          habitats; ecosystems and biomes;

          interrelationships among resources and an

          environmental system; sources and flow of energy

          though an environmental system; relationship

          between carrying capacity and changes in

          populations and ecosystems; and changes in

          environments.

     

     (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.

§112.46. Aquatic Science (one credit).

(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 10, 11, or 12.



(b)  Introduction.



     (1)  In Aquatic Science, 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: components of an aquatic ecosystem;

          relationships among aquatic habitats and

          ecosystems; roles of cycles within an aquatic

          environment; adaptations of aquatic organisms;

          changes within aquatic environments; geological

          phenomena and fluid dynamics effects; and origin

          and use of water in a watershed.

     

     (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.

          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.

§112.49. Geology, Meteorology, and Oceanography (one credit).

(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
