What is ”Science”?
Science… is made up of mistakes, but
they are mistakes which it is useful to
make, because they lead little by little to
the truth.” –Jules Vern
What is ”Science”
Science is not a ‘thing’, but a way of thinking.
Focus of science is the natural world
Can be used to understand anything that is Observable
Observable: able to be experienced using the senses
Science changes over time to give the best explanation possible
The noticing and describing of events or processes.
Observations rely on our senses, or on scientific instruments
which enhance our senses.
Observations can be:
Qualitative: use adjectives and descriptions
Quantitative: use measurements and numbers
A possible explanation for a set of observations, or a possible
answer to a scientific question. A good hypothesis should
offer predictions that are testable
A representation of an idea, object, system, or process which
is used to explain something that cannot be experienced
directly. Similar to a hypothesis.
Types of model include conceptual (ideas), mathematical,
A guess, based on observations, hypothesis, or theory, which
is observable and testable.
A well tested explanation that unifies a broad range of
observations and hypotheses, and enables scientists to make
accurate and testable predictions about new situations.
Theories will change to incorporate and explain new
observations, or will be replaced by better theories
Ex: Theory of Gravity, Theory of Relativity, Germ Theory,
Theory of Evolution, Molecular Theory, Theory of Plate
