Catalog Course Description

This course includes the study of astronomy, physics, chemistry, geology, and meteorology. Special emphasis is placed on student experimentation and observation. This course format will include activity-based investigations with hands-on activities, concepts, and applications compliant with the adopted California State Science Standards to meet the minimum course requirements for high school graduation. 60 lecture hours.

Course Objectives

  • Describe the differences and similarities between the sun, the terrestrial planets, and the gas planets during the formation of the solar system.
  • Explain the origin and effects of temperature inversions.
  • Outline the properties of ocean water, including temperature, salinity, horizontal and vertical ocean currents, the layered structure of the ocean, and the geographic distribution of marine organisms.
  • Explain the interaction between wind patterns, ocean currents, and mountain ranges, and how those interactions relate to the latitudinal bands of rain forests and deserts.
  • Understand the global carbon cycle.
  • Understand the importance of water to society, the origins of California, and the relationship between supply and demand.
  • Explain the geological differences between early Earth and other planets and Earth today.
  • Describe the effects that asteroid impacts have in shaping the surface of planets and their moons and in mass extinctions of life on Earth.
  • Explain the different life cycles of a star.
  • Describe the relationship between a star's color, brightness, evolution, and gravitational collapse.
  • Describe the relationship between a star's color, brightness, evolution, and nuclear fusion.
  • Explain the properties of the ocean floor (magnetic patterns, age, and seafloor topography).
  • Explain the properties of rocks based on the physical and chemical conditions in which they formed, including plate tectonics.
  • Describe two kinds of volcanoes - violent and voluminous.
