CHAPTER     The Nature of Science and
  1.2        Scientific Inquiry
Science is the process of learning about
the 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.

                 to investigate and answer questions about the world.

All scientific investigations use similar
                               processes to find answers to questions.

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
