    research and describe the historical development of the Big Bang Theory (ASTR5.B)
    interpret data concerning the formation of galaxies and our solar system (ASTR5.C)

Science Concepts. The student knows the characteristics and the life cycle of stars. The student is expected to (ASTR6):

    describe nuclear reactions in stars (ASTR6.A)
    identify the characteristics of stars such as temperature, age, relative size, composition, and radial velocity using spectral analysis (ASTR6.B)
    identify the stages in the life cycle of stars by examining the Hertzsprung-Russell diagram (ASTR6.C)

Science Concepts. The student knows how mathematical models, computer simulations, and exploration can be used to study the universe. The student is expected to (ASTR7):

    demonstrate the use of units of measurement in astronomy such as light year and Astronomical Units (ASTR7.A)
    research and describe the historical development of the laws of universal gravitation and planetary motion and the theory of special relativity (ASTR7.B)
    analyze a model that simulates planetary motion and universal gravitation (ASTR7.C)
    identify the historical origins of the perceived patterns of constellations and their role in ancient and modern navigation (ASTR7.D)
    analyze the impact of the space program on the collection of data about the Earth and the universe (ASTR7.E)

Science Concepts.The student knows the role of the Sun in our solar system. The student is expected to (ASTR8):

    identify the approximate mass, size, motion, temperature, structure, and composition of the Sun (ASTR8.A)
    identify the source of energy within the Sun and explain that the Sun is the major source of energy for the Earth (ASTR8.B)
    describe the Sun's effects on the Earth (ASTR8.C)

Science Concepts. The student knows that planets of different size, composition, and surface features orbit around the Sun. The student is expected to (ASTR9):

    observe the night-time sky to determine movement of the planets relative to stars (ASTR9.A)
