Steps of the scientific
investigation

The Scientific Method
The Scientific Method is a series of steps that you can
plan to answer questions and testing possible answers.
Galileo Galilei is the Father of Modern Science for his
description of the Scientific Method.
The Scientific Method
It is a procedure used to provide scientific explanations
for questions about the world around us. It outlines a way
a scientific can perform an experiment to collect
empirical data which can be used to answer a question.
The scientific plans his experiment based on background
research that leads to a hypothesis predicting what may
happen.
When the experiment is complete, the scientific uses the
data to form a conclusion.
Making Observations
An observation is anything detected
by the senses, which include sight,
hearing, touch, smell, and taste.
Making Observations
Let’s say you take want to make
your plants grow better and
faster.
You have some options that can
help you out: organic soil and
fertilizer.
You can touch, see, and smell
them.
Asking a Question
Observations often lead to questions.
This is the problem the scientist is
looking to solve.
The question should be objective and
testable. It should be answered with
data collected by observation or
testing.
A testable question should not be a
question about opinion.
Background Research
The background is the information
that is already available from other
experiments about the topic of your
investigation.
Use reliable sources. Search for the
object of your question. Use books
and internet.
Search for the type of plant you
want to grow. Is anyone else
doing research on fertilizers?
Forming a Hypotheses
A hypothesis is a possible
answer the scientific question.
A hypothesis must be based on
scientific knowledge, and must
be logical.
It should be able to prove true or
false.
