COURSE CONCEPT—The overarching theme of the third year is that the Earth changes over time. These changes are inherently interrelated in a cause-and-effect fashion with changes in both abiotic and biotic systems. Year three continues to build upon the standards studied in Integrated Science 1 and 2, including standards from physics, chemistry, biology, and earth science. The physics standards studied in the third year pertain to motion and forces, conservation of energy and momentum, and electric and magnetic phenomena. The chemistry standards include conservation of matter and stoichiometry, gases and their properties, acids and bases, solutions and reaction rates, and chemical equilibrium. The biology standards include cell biology, genetics, and evolution. The earth science standards, which relate to the study of the Earth’s atmosphere, provide the foundations upon which each of the foregoing scientific disciplines will be taught. The Integrated Science 3 concepts will be further enhanced by having students perform careful scientific investigations.

  • I.

    Semester 1—Universal laws of nature Semester one focuses on certain universal laws of matter and energy as they apply to the changes in the physical structure and chemical composition of the Earth and its atmosphere.

    • A.

      Unit Concept #1—Certain universal laws of nature govern the composition of matter. These include the theory and application of the law of conservation of matter, in terms of both number and mass, the kinetic molecular theory particularly as applied to the study of gases, and the concept of the mole.

      • 1.

        Earth 8a- Students know the thermal structure and chemical composition of the atmosphere.

        • a.

          Chemistry 4d- Students know the values and meanings of standard temperature and pressure (STP).

          • (i)

            Chemistry 4e- Students know how to convert between the Celsius and Kelvin temperature scales.

          • (ii)

            Chemistry 4f- Students know there is no temperature lower than 0 Kelvin.

        • b.

          Chemistry 3d- Students know how to determine the molar mass of a molecule from its chemical formula and a table of atomic masses and how to convert the mass of a molecular substance to moles, number of particles, or volume of gas at standard temperature and pressure.

          • (i)

            Chemistry 3c- Students know one mole equals 6.02 x 1023 particles (atoms or molecules).

          • (ii)

            Chemistry 3b- Students know the quantity one mole is set by defining one mole of carbon 12 atoms to have a mass of exactly 12 grams.
