Title: Discovery science emphasizes inquiry and observation


1
Discovery science emphasizes inquiry and
observation
  • 2.1

2
Science as Inquiry
  • The word science is derived from a Latin verb to
    know.
  • At the heart of science is inquiry people
    asking questions.
  • Your own curiosity is the starting point for
    exploring life through inquiry.

3
Observations and Data
  • The questions that drive scientific inquiry are
    based on observations.
  • Observations the use of senses
  • Recorded observations are called data.
  • All observations depend on human senses.

4
  • Observations are often recorded as measurements,
    also called quantitative data.
  • Data may also be qualitative, in the form of
    descriptions instead of measurments.

5
What is Discovery Science?
  • Discovery science, also called descriptive
    science, describes natural structures or
    processes.
  • Sometimes things are discovered by accident in
    discovery science.
  • Alexander Fleming accidentally discovered
    Penicillium.

6
Inferences in Science
  • An inference is a logical conclusion based on
    observations.
  • Inferences are important in science because the
    help refine general questions into specific
    questions.

7
Generalizations in Discovery Science
  • Generalization is a general conclusion.
  • Some of the largest breakthroughs in science have
    come when scientists have put many specific
    observations together to reach a generalization.
  • It is also possible to generalize quantitative
    data.
  • Observations, data, inferences, and
    generalizations all advance peoples
    understanding of life.
