DoNow: Determine what’s inside the bottle
If the current technology cannot
open the bottle, how can you
find out what’s inside?
Discuss it with your partner and
write down 3 innovative ways

Consequences
The Real World
Physics – A Scientific World View
Scientific Method
 Einstein’s view of scientific processes
☛ A scientist makes a creative leap based on intuition
to explain physical phenomena
☛ The scientific process begins when the scientist
develops consequences based on the idea/axiom
☛ A powerful idea/axiom has many consequences
☛ Test these consequences against the real world

Scientific Attitude
Physics – A Scientific World View
Scientific Attitude
 Fact – A close agreement by competent
observers who make a series of
observations of the same phenomenon
Fact

Scientific Attitude
 Hypothesis – An educated guess that is
only presumed to be factual until
demonstrated by experiment
Scientific hypotheses must be testable
Hypothesis

Scientific Attitude
 Concept – An intellectual framework that
is part of a theory encompasses the
overriding idea that underlines various
phenomena
Concept
