COURSE CONCEPT—The overarching concept for Integrated Science 2 is that the Earth is a unique system that supports life within an ever-changing and complex universe. Building upon the standards covered in Integrated Science 1, this theme includes standards taken from physics, chemistry, biology, and Earth science. Included among the standards from physics are those pertaining to energy and Newton’s Laws. In chemistry, the standards pertain to solutions, chemical reactions, and organic chemistry. The biology standards include considerations of molecules, cells, protein synthesis, cell reproduction, and Mendelian genetics. Earth science standards pertain to planetary motion, solar radiation, energy transformations at the Earth’s surface, and geological and climatic changes. The Integrated Science 2 concepts will be further enhanced by having students perform careful scientific investigations.


Semester 1—The formation and motion of planets.

  • A.

    Unit Concept #1—The interaction of matter and energy result in a dynamic solar system that can be explained by the universal laws of physics. Forces affect planetary systems, and universal laws of energy and motion explain the movement of planets and all other objects. Universal laws can be observed by studying simple systems, and Newton’s laws of motion help to explain simple and universal systems. Inherent in any useful study of motion is the concept of force, and Newton’s laws provide a solid foundation upon which to analyze forces. There is an important relationship between the universal law of gravitation and the effect of gravity on an object at the surface of the Earth. Celestial and earth systems are affected by the same forces as explained by Newton’s Laws.
