  1. 1. 1.1The Nature of Science
  2. 2. 1.1 The Nature of Scientific Inquiry •1What is Science? A means of explaining & understanding the natural world Using facts, laws & theories
  3. 3. 1.1 The Nature of Scientific Inquiry •1What is Science? A means of explaining & understanding the natural world Using facts, laws & theories What we observe
  4. 4. 1.1 The Nature of Scientific Inquiry •1What is Science? A means of explaining & understanding the natural world Using facts, laws & theories What we observe Statement of what happened
  5. 5. 1.1 The Nature of Scientific Inquiry •1What is Science? A means of explaining & understanding the natural world Using facts, laws & theories What we observe Statement of what happened Explanation of observations or Laws
  6. 6. Observations & Facts / Laws / Hypothesis & Theories M1 M 2 Fg = d2
  7. 7. Observations & Facts / Laws / Hypothesis & Theories M1 M 2 Fg = d2
  8. 8. Observations & Facts / Laws / Hypothesis & Theories M1 M 2 Fg = d2
  9. 9. Observations & Facts / Laws / Hypothesis & Theories M1 M 2 Fg =Sir Isaac Newton’s Law of Gravity d2 Observed all objects in universe exerting gravitational force on each other Force between objects increases as MASS increases Force between objects decreases as DISTANCE b/w incr.
  10. 10. Observations & Facts / Laws / Hypothesis & Theories M1 M 2 Fg =Sir Isaac Newton’s Law of Gravity d2 Observed all objects in universe exerting gravitational force on each other Force between objects increases as MASS increases Force between objects decreases as DISTANCE b/w incr.Hypothesis Theory
  11. 11. Observations & Facts / Laws / Hypothesis & Theories M1 M 2 Fg =Sir Isaac Newton’s Law of Gravity d2 Observed all objects in universe exerting gravitational force on each other Force between objects increases as MASS increases Force between objects decreases as DISTANCE b/w incr.Hypothesis  widely accepted by science Theory community after testing
  12. 12. Types of Scientific Knowledge
  13. 13. Types of Scientific KnowledgeEmpirical IndigenousKnowledge Knowledge (IK) or Traditional Ecological Knowledge & Wisdom (TEKW)
  14. 14. Types of Scientific Knowledge Empirical Indigenous Knowledge Knowledge (IK) or Traditional EcologicalThrough careful Knowledge & Wisdom (TEKW)observation &experimentation Through experience with environment & resulting observations

  20. 20. Misunderstandings about science
  21. 21. All scientists followscientific methodno 1 methodare methodical Misunderstandings about science
  22. 22. All scientists follow Science = Experimentationscientific method  sometimesno 1 method  only observations at timesare methodical Misunderstandings about science
  23. 23. All scientists follow Science = Experimentationscientific method  sometimesno 1 method  only observations at timesare methodical Misunderstandings about Investigations = proof science  only real proof, is to disprove
  24. 24. All scientists follow Science = Experimentationscientific method  sometimesno 1 method  only observations at timesare methodical Misunderstandings about Investigations = proof science  only real proof, is to disprove Science can answer all questions  moral ethical, social questions can’t be solved by science
  25. 25. All scientists follow Science = Experimentation scientific method  sometimes no 1 method  only observations at times are methodical Misunderstandings about Investigations = proofScience isn’t very  only real proof, is sciencesuccessful to disprove not perfect, but agreat deal ofsuccess always room for Science can answer all questionsmore discoveries!  moral ethical, social questions can’t be solved by science

  32. 32. Is Science = Technology?
  33. 33. Is Science = Technology? Closely related: often advance together  lens, spotting scope, telescope & Galileo  new inventions often lead to new discoveries laser invented prior to having a use for it
  34. 34. Is Science = Technology? Closely related: often advance together  lens, spotting scope, telescope & Galileo  new inventions often lead to new discoveries laser invented prior to having a use for it A mutually beneficial relationship
