welcome to moomoomath and science in
this video I'd like to go through the
steps of the scientific method in three
minutes or less the scientific method is
a systematic way to find answers to
questions or problems step 1 identify
the problem what would you like to know
problems are written in the form of a
question
step 2 is research the research can be
in the form of looking on the internet
talking to other people reading
scientific books magazines etc step 3 is
form a hypothesis which is an educated
guess the hypothesis should be based on
research or life experience step 4 is
design and experiment the experiment
should be designed to test the
hypothesis and during the experiment
observations are used to collect
measurable data the experiment will
include three variables first variable
is the independent variable it is the
part of the experiment that you change
to see how it affects the dependent
variable the independent variable is
always graphed on the x-axis the
the dependent variable is the part of the
an experiment that changes in response to
the independent variable the dependent
the variable is always graphed on the y-axis
and then you have control variables
these are variables that should be held
constant and are used for comparing in
addition a large sample size increases
the accuracy of the experiment and
results and many times you need to
repeat the experiment several times to
insure against errors that may be
introduced
Step five results this is the
information that you have gathered
quantitative data is data that is
numbered many times it is recorded on
charts tables and graphs qualitative
data includes illustrations and
photographs and this is data that is
observed and finally step six is the
conclusion and during the conclusion you
give a summary of the overall results
and you state whether or not you accept
or reject your hypothesis and then
describe if there's any practical
application to what you have learned so
there we go
this six steps of the scientific method
