Good day!  We are going to talk about the Nature of Science
Methods of Scientific Study
aka we call this the Scientific Method.  This is what scientists use
on a daily basis and its essentially
discipline to investigate and understand nature, that is what science is
organized way of using evidence to learn about the natural world.
Scientists use the scientific method on a daily basis to
help solve problems that they encounter.
 
Here are two different orders of the scientific method.
On the left we have problem, hypothesis, experiment
observation, record & repeat experiment, conclusions
and communicate results.  This is the one that I tend to use
I use the acronym PHEORCC
PHEORCC which
stands for problem, hypothesis, experiment, observation, record/repeat
conclusion and communicate results.  But you don't have
to do it in that order.  You can do it in the order that is on the right.
where you have a problem and you ask a question
and maybe you make some observations
do some research, formulate your hypothesis, you design
your experiment.  While you carrying out your experiment you record
some data.  You are always going to repeat the experiment
draw conclusion and communicate results.
So the first thing that is going to happen is that you are
going to encounter a question or a problem that
you need help to solve using experimentation.
