of Chapter 1 The Nature of Science
The word science comes from the Latin word
scientia, meaning knowledge.
  • Mr. Manskopf
  • Notes can also be found at http//www.manskopf.com

Goals for these notes

What Science is and is not
  • Science is an organized way of studying the
    natural world, and the knowledge gained from such
    studies.
  • Science assumes that the natural world functions
    in accordance with rules that do not change.
  • Science does not deal with the supernatural.
  • Science relies on evidence from measurements and
    observations.
  • Scientific ideas are supported, not proven,
    and accepted, not believed in.

How Science Works
  • In order to satisfy our curiosity about why
    things are the way they are and about how things
    happen the way they do, we must..

Hypothesis and Predicting
  • Is a testable idea that can be lead to further
    investigation.
  • Can you give an example?

Hypothesis
  • Cholera is caused by people drinking contaminated
    water.
  • Which pump appears to be causing the 1854 London
    Cholera outbreak?
  • Spot Map
  • See patterns in data
  • How could you test this hypothesis?

14
Collecting Data
  • To study the hypothesis data must be collected
    and analyze.
  • Conclusions must be drawn
  • Results must be repeatable
  • Results should be communicated

21
Community Analysis and Feedback Peer Reviewed
Present their work and get feedback from other
researchers at conferences Write papers about
their study Submit papers for publication in a
journal
22
Habits of a Scientist
  • Curiosity
  • Skepticism
  • Openness to New Ideas
  • Intellectual Honesty
  • Imagination and Creativity

impacts on the environment?

ethical standards to the relationship between
humans and the environment. Anthropocentrism
Humans and human welfare most important Biocentris
m All living things have value some may be more
important than others Ecocentrism Well-being of
