Transcript

  • 1. Important Terminology Regarding Scientific Inquiry
    • Hypothesis: Possible explanation for how or why things happen. Must be testable.
    • Theory: An explanation for how something works that has been well tested and widely accepted by the scientific community.
  • 2. Experimental Design: Variables
    • Variables: Factors that can change in an experiment.
    • Manipulated Variable (independent variable): factor that scientists change.
    • Responding Variable (dependent variable): factor that may change because of the manipulated variable.
  • 3.
    • Controlled Variable: The variables that scientists keep the same.
    • Experimental Group: The group in an experiment where the manipulated variable is changed.
    • Control Group: The group in an experiment where no variable is changed so it can be used as a standard of comparison.
  • 4. Operational Definition
    • Describes how a particular variable is to be measured.
  • 5. What is Earth Science?
  • 6.  
  • 7. Overview of Earth Science
    • Earth Science is the name for the group of sciences that deals with Earth and its neighbors in space .
  • 8. Geology
    • Means “study of Earth”.
    • Divided into two areas: physical geology and historical geology
  • 9. Physical Geology
    • Includes the study of Earth materials like rocks and minerals.
    • Includes study of processes that shape our planet.
  • 10.  
  • 11. Historical Geology
    • Study of Earth’s history by the establishment of a timeline of the physical and biological changes that have occurred since Earth was formed.
  • 12.  
  • 13. Oceanography
    • Scientific study of the ocean.
    • Includes study of physical ocean, chemical makeup of ocean, ocean life, ocean movement, and geology of seafloor.
  • 14. Meteorology
    • The study of atmospheric processes which allow scientists to predict the weather and climate .
  • 15. Astronomy
    • Study of the Universe .
    • Study the origin, movement, emissions and development of:
        • Galaxies
        • Stars
        • Planets
        • Moons
        • Celestial Objects (comets, meteors etc.)
