  1. Chapter 1 Introduction to Earth Science

  2. Standards • SCSh1. Evaluate the importance of curiosity, honesty, openness, and skeptics in science. • SCSh3. Identify and investigate problems scientifically. • SCSh7. Analyze how scientific knowledge is developed. • SCSh8. Understand important features of the process of scientific inquiry.

  3. The Earth Explained Long Ago • Ra • Poseidon

  4. Current Study of the Earth • Geology • Oceanography • Meteorology • Astronomy • Environmental Science

  5. Scientific Process • Questions based on observations • Hypothesis “If……, then…..” • Experiments test the hypothesis • Analysis of data derived from experiment • Conclusion

  6. Scientific Process

  7. Experiments • Independent Variable • Dependent Variable • Constants • Control Group

  8. Data Measurements • International System of Units (Metric System) • Units of 10 (K H D B D C M) • Length • Mass • Volume • Temperature

  9. Models • Computer models test systems that cannot be tested through experiments: • Environmental issues
