Title: Intro to Scientific Inquiry


1
Intro to Scientific Inquiry
2
Scientific Inquiry
  • Science used as a body of knowledge to understand
    how the world works
  • Scientific explanations result from a combination
    of observations and what people already know
    about the world
  • Ask questions!
  • Leads to experiments, collecting data, drawing
    conclusions
  • Scientific knowledge subject to change and
    modification

3
The Scientific Method
  • Making observations
  • Asking questions
  • Developing a hypothesis
  • Designing an experiment
  • Collecting data
  • Making inferences
  • Results (peer review)

4
Observation
  • def. - the process of obtaining information by
    using the senses
  • Examples
  • A bottle of seltzer water is sitting in a ice
    bath.
  • There is salt in the ice bath.
  • The unopened seltzer water is in liquid form.
  • The bottle is cold to the touch.
  • (After opening the bottle, the seltzer water
    freezes.)

5
Question/Problem
  • Based on what is known and observed, what
    question or problem do we want to solve in order
    to better understand the scientific world?
  • Example
  • What will happen to the bottle of seltzer water
    when opened?
  • (Why did the seltzer water in the bottle freeze
    after it was opened?)

6
Hypothesis
  • def a theory or explanation that is based on
    observations and that can be tested
  • The if-then hypothesis
  • I think that if, then
  • Why is the hypothesis so important to scientific
    inquiry?

7
Hypothesis continued
  • Examples
  • I think that if a bottle of seltzer water from
    an ice bath is opened, then the bottle will
    explode.
  • I think that if a bottle of seltzer water from
    an ice bath is opened, then the water inside will
    freeze.
