  24. Major Sciences of ES

  25. Major Sciences of ES • Astronomy Cartwheel galaxy www.nasa.gov Study of objects beyond our Earth’s atmosphere

  26. Major Sciences of ES • Astronomy • Meteorology The study of air the surrounds Earth (and it’s affect on weather) www.noaa.gov

  27. Major Sciences of ES • Astronomy • Meteorology • Geology Study of materials that make of the Earth

  28. Major Sciences of ES • Astronomy • Meteorology • Geology • Oceanography Study of the Earth’s oceans

  29. Main Earth Systems

  30. Main Earth Systems • Lithosphere Rigid outer shell of the planet: includes crust and mantle

  31. Main Earth Systems • Lithosphere • Hydrosphere The water portion

  32. Main Earth Systems • Lithosphere • Hydrosphere • Atmosphere The layer of gases that surround the planet

  33. Main Earth Systems • Lithosphere • Hydrosphere • Atmosphere • Biosphere The part of Earth that includes life.

  34. Science and Technology We often develop new things as a result of scientific discovery

  35. The End

  36. Objectives Methods of Scientists – 1.2 • List steps used in scientific method • Compare experimental variables and controls • Identify basic SI units • Explain how to write numbers in scientific notation

  37. Scientific Method Organized approach to solving problems

  38. Scientific Method • Question or Problem

  39. Scientific Method • Question or Problem • Do background research

  40. Scientific Method • Question or Problem • Do background research • Make hypothesis An educated, testable guess for an observation

  41. Scientific Method • Question or Problem • Test (experiment) • Control • Variable Study of the Earth’s oceans

  42. Scientific Method • Question or Problem • Test (experiment)

  43. Scientific Method • Question or Problem • Test (experiment) • Control The experiment by which the other is compared

  44. Scientific Method • Question or Problem • Test (experiment) • Control • Variable The factor that is changed

  45. Scientific Method • Question or Problem • Test (experiment) • Control • Variable • Independent variable Variable altered by experimenter

  46. Scientific Method • Question or Problem • Test (experiment) • Control • Variable • Independent variable • Dependent variable Variable that changes as a result of the indep. variable

  47. Scientific Method • Question or Problem • Test (experiment) • Organize/Analyze results

  48. Scientific Method • Question or Problem • Test (experiment) • Organize/Analyze results • Make a table

  49. Scientific Method • Question or Problem • Test (experiment) • Organize/Analyze results • Make a table • Make a graph
