Transcript of "Ch1.2"

  1. 1. 1.2The Nature of Scientific Inquiry
  2. 2. CHAPTER The Nature of Science and 1.2 Scientific Inquiry
  3. 3. CHAPTER The Nature of Science and 1.2 Scientific InquiryScience is the process of learning aboutthe world we live in by asking questions.
  4. 4. CHAPTER The Nature of Science and 1.2 Scientific InquiryScience is the process of learning aboutthe world we live in by asking questions. Science uses observations (what you can see, hear, touch, smell, or taste) to investigate and answer questions about the world.
  5. 5. CHAPTER The Nature of Science and 1.2 Scientific InquiryScience is the process of learning aboutthe world we live in by asking questions. Science uses observations (what you can see, hear, touch, smell, or taste) to investigate and answer questions about the world.All scientific investigations use similar processes to find answers to questions.
  6. 6. CHAPTER The Nature of Science and 1 Scientific InquiryThe knowledge obtained from scientific inquiry allows new technologies to be invented.
  7. 7. CHAPTER The Nature of Science and 1 Scientific InquiryThe knowledge obtained from scientific inquiry allows new technologies to be invented.With your nearest neighbour, create a step-by-step plan describing how you would answer the question: “Which of three similar brands of gum is the stickiest when chewed?”

  15. 15. Questioning• HOW?• WHY?• WHAT?• WHERE?• WHEN? • Have to ask the appropriate question
  16. 16. Hypothesizing• A Hypothesis is a possible explanation that accounts for the observations you have made.
  17. 17. Hypothesizing• A Hypothesis is a possible explanation that accounts for the observations you have made.• Must be testable
  18. 18. Hypothesizing• A Hypothesis is a possible explanation that accounts for the observations you have made.• Must be testable• Your aim is to SUPPORT or REJECT hypothesis
  19. 19. Hypothesizing• A Hypothesis is a possible explanation that accounts for the observations you have made.• Must be testable• Your aim is to SUPPORT or REJECT hypothesis• MUST have 2 variables: independent & dependent variable
  20. 20. Hypothesizing• A Hypothesis is a possible explanation that accounts for the observations you have made.• Must be testable• Your aim is to SUPPORT or REJECT hypothesis• MUST have 2 variables: independent & dependent variable• Serves 2 jobs: suggests explanation & guides investigation
  21. 21. Predicting• Hypothesizing is the ‘why’ something happens,• The Predicting is what you think will happen
  22. 22. Planning• Design appropriate investigation Controlled Experiment Correlational Study Observational Study
  23. 23. Controlled Experiment • A controlled experiment is a test in which only one variable is changed to observe its effect on a second variable, while holding all other variables in the experiment constant (in “constant control”).
  24. 24. Correlational Study• Correlational studies test how one variable affects another variable without attempting to control the other variables. No correlation
  25. 25. Observational Study• Observational studies involve observing a subject or phenomenon in a structured manner that does not interfere with the nature of the subject or phenomenon.
  26. 26. Conducting• Follow your plan
  27. 27. Recording• Qualitative and Quantitative observations without with numbers numbers (colour, smell) (counting, measuring)
  28. 28. Analyzing• review tables,• create graphs• check for errors, assumptions, biases
  29. 29. Evaluating• Judge findings – What went well? – What were the challenges? – What would you do differently next time?• Identify errors• Discuss results
  30. 30. Synthesizing• What to do with what you learned?• What to do next?
  31. 31. Communicating• Clear, accurate sharing of information• Most common = lab report
