  • Chapter 1 The World of Earth Science The Scientific Method in Earth Science Section 2
  • The Scientific Method
    • A series of steps that scientists use to answer questions & solve problems
  • The Scientific Method
    • The Scientific Method involves 7 steps:
            • Make Observations
            • Ask a Question
            • Form a Hypothesis
            • Test your Hypothesis
            • Analyze the Results
            • Draw Conclusions
            • Communicate the Results
  • The Scientific Method Make Observations - You observe something in the material world, using your senses or machines which are basically extensions of those senses. AH—Look at this!
  • The Scientific Method Ask a Question - You ask a question about what you observe. State the problem or question.
  • The Scientific Method Form a Hypothesis - You predict what you think the answer to your question might be
  • The Scientific Method Test your Hypothesis - You figure out a way to test whether hypothesis is correct. The outcome must be Measurable. Record and analyze data.
  • The Scientific Method Analyze the Results - You do the experiment using the method you came up with and record the results. You repeat the experiment to confirm Your results by retesting.
  • The Scientific Method Draw Conclusion - You state whether your prediction was confirmed or not and try to explain your results.
  • The Scientific Method
    • Communicate Results – Share what is learned with other scientists
  • The Scientific Method
  • Chapter 1 The World of Earth Science Life in a Warmer World – An Earth Science Model Section 3
  • Global Warming
    • Worldwide increase in temperature
  • Effects of Global Warming
    • Rotting Remains – Rate of decay would increase if the Earth’s temperature rose
  • Effects of Global Warming
    • Ice is Nice – Warmer Temperatures mean that much of the ice would melt
  • Effects of Global Warming
    • Water, Water Everywhere – As temperature increased the volume of the oceans would expand
  • Effects of Global Warming
    • Rain, Rain Go Away – There would be more rain
  • Models
    • Representations of objects or systems
  • Physical Models
    • Models that you can touch
  • Mathematical Models
    • Model made up of math equations & data
  • Conceptual Models
    • System of ideas
  • Theory
    • A unifying explanation for a broad range of hypothesis & observations
  • Greenhouse Effect
    • Global-warming
  • Chapter 1 The World of Earth Science Measurement & Safety Section 4
  • SI
    • International System of Units
  • Length/Volume/Mass/Temp
  • Meter(m)
    • Basic unit of length in the SI system
  • Volume
    • Amount of space something occupies
  • Mass
    • Amount of matter something is made of
  • Temperature
    • A measure of how hot or cold something is
