  22. 22. 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!
  23. 23. The Scientific Method Ask a Question - You ask a question about what you observe. State the problem or question.
  24. 24. The Scientific Method Form a Hypothesis - You predict what you think the answer to your question might be
  25. 25. 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.
  26. 26. 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.
  27. 27. The Scientific Method Draw Conclusion - You state whether your prediction was confirmed or not and try to explain your results.
  28. 28. The Scientific Method <ul><li>Communicate Results – Share what is learned with other scientists </li></ul>
  29. 29. The Scientific Method
  30. 30. Chapter 1 The World of Earth Science Life in a Warmer World – An Earth Science Model Section 3
  31. 31. Global Warming <ul><li>Worldwide increase in temperature </li></ul>
  32. 32. Effects of Global Warming <ul><li>Rotting Remains – Rate of decay would increase if the Earth’s temperature rose </li></ul>
  33. 33. Effects of Global Warming <ul><li>Ice is Nice – Warmer Temperatures mean that much of the ice would melt </li></ul>
  34. 34. Effects of Global Warming <ul><li>Water, Water Everywhere – As temperature increased the volume of the oceans would expand </li></ul>
  35. 35. Effects of Global Warming <ul><li>Rain, Rain Go Away – There would be more rain </li></ul>
