Ch1.2 Ch1.2 Presentation Transcript

  • 1.2The Nature of Scientific Inquiry
  • CHAPTER The Nature of Science and 1.2 Scientific Inquiry
  • CHAPTER The Nature of Science and 1.2 Scientific InquiryScience is the process of learning aboutthe world we live in by asking questions. View slide
  • 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. View slide
  • 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.
  • CHAPTER The Nature of Science and 1 Scientific InquiryThe knowledge obtained from scientific inquiry allows new technologies to be invented.
  • 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?”

  • Questioning• HOW?• WHY?• WHAT?• WHERE?• WHEN? • Have to ask the appropriate question
  • Hypothesizing• A Hypothesis is a possible explanation that accounts for the observations you have made.
  • Hypothesizing• A Hypothesis is a possible explanation that accounts for the observations you have made.• Must be testable
  • 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
  • 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
  • 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
  • Predicting• Hypothesizing is the ‘why’ something happens,• The Predicting is what you think will happen
  • Planning• Design appropriate investigation Controlled Experiment Correlational Study Observational Study
  • 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”).
  • Correlational Study• Correlational studies test how one variable affects another variable without attempting to control the other variables. No correlation
  • 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.
  • Conducting• Follow your plan
  • Recording• Qualitative and Quantitative observations without with numbers numbers (colour, smell) (counting, measuring)
  • Analyzing• review tables,• create graphs• check for errors, assumptions, biases
  • Evaluating• Judge findings – What went well? – What were the challenges? – What would you do differently next time?• Identify errors• Discuss results
  • Synthesizing• What to do with what you learned?• What to do next?
  • Communicating• Clear, accurate sharing of information• Most common = lab report
  • Scientific Method
  • Scientific Method
  • 10 Parts to the Scientific Method
  • Identify the Problem
  • Identify the Problem Form a Hypothesis
