You’ve
just
been
Scienced!


• Science:
the
methodological
approach
to
the


acquisi@on
of
knowledge



The
Scien@fic
Method


1. Observa@on
(reading)


2. Hypothesis


– An
educated
guess


3. Predic@on


– If
/
then
logic


4. Tes@ng,
Experimenta@on,
Data
Collec@on


– Observa@ons,
comparisons,
experiments


5. Analyzing
and
Evalua@ng
Data


– Do
the
results
support
the
Hypothesis?


– Is
our
ini@al
hypothesis
s@ll
valid?


6. Repor@ng
Results


– Posters,
papers,
presenta@ons,
peer‐reviewed
journals

Observa@onal
or
Compara@ve
Studies


• Collect
data
without
manipula@on


– Are
there
more
males
or
females
in
this


classroom?


– Are
these
two
organisms
different
species?



• Observa@onal
studies
o-en
done
first


– Good
at
what’s
happening


– Not
good
at
why

Observa@ons
vs.
Experiments


• Observa@ons
answer
the
what.


– Is
something
going
on?


• Experiments
answer
the
why
or
how
much,
etc.


– Includes
treatment
groups
and
control
groups


– How
much
is
something
affec@ng
the
system?


– How
long
will
it
take?



Try
some
science:
Biology


• How
should
this


ques@on
be
set
up
so
it


can
be
answered


scien@fically?


• Treatment?


• Control?
