The Scientific Method

Report
Scientific Method is the way scientists
learn and study the world around
them.



The basis of scientific method is asking questions and then trying to
come up with answers
Just about everything begins with a question and someone has an
urge to answer that question
Its as easy as asking “Why do cats and dogs have hair?”
 One answer could be that it keep them warm
Scientific Method is a rational,
logical thought process that is
used to figure out facts and
truths
•Statements must be confirmed with loads
of evidence
• Scientist start with observations and then
make a hypothesis (an educated guess)
• Then starts the fun by proving the
hypothesis through many different trials
and test to show why the data and results
are correct.
•Using controls which quantitative
(based on values and figures, not
emotions)
•Qualitative is pertaining to or
concerned with quality or qualities
•Scientist can examine their data and
develop newer ideas
•This process will lead to more
observation and refinement of
hypotheses.
There are different terms used to describe scientific ideas
based on the amount of confirmed experimental
evidence.
Hypothesis
- a statement that uses a few observations
- an idea based on observations without experimental evidence
Theory
- uses many observations and has loads of experimental evidence
- can be applied to unrelated facts and new relationships
- flexible enough to be modified if new data/evidence introduced
Law
- stands the test of time, often without change
- experimentally confirmed over and over
- can create true predictions for different situations
- has uniformity and is universal
A model is a scientific statement that has some experimental validity or is
a scientific concept that is only accurate under limited situations.
 QUESTION
1:
The scientific method was developed to help
scientists organize the process of solving
problems.
True
False
 The
scientific method is an objective stepby-step way of looking at natural events.
When anyone has a question about the world
around them, they use these methods and
procedures to explain and answer that
question. The scientific method can also be
used to prove (or disprove) the statements of
another scientist or person. The entire
process requires observable and quantifiable
evidence and data.

 QUESTION
2:
Which of these is not a step of the scientific
method?
Hypotheis
Experiment
Conclusion
Plagiary
There are about six basic steps in the scientific method
of solving problems. You have to start with a problem
or question and then develop a hypothesis that offers
an answer to the question. You then develop and
perform an experiment and record your results. You
finish with an analysis of your results and develop a
conclusion that would (hopefully) answer the original
question.

Question 3
Which of these words would you NOT associate
with the scientific method?
Disorganized
Organized
Data
Control
The scientific method creates
an organized framework that
helps scientists (and
everyone) solve problems. As
you complete an experiment
that tests variables and has
controls, you record data and
results.

QUESTION 4:
A hypothesis is...
A Random Thought
An Answer
An Educated Guess
An Experiment
A hypothesis is an educated
guess that offers a possible
answer to a problem. An
experiment must be
developed to prove the
accuracy of the hypothesis.

QUESTION 5:
Which of these would be called results?
Number of Fruit Flies
Counting Fruit Flies
Seeing Fruit Flies on an Apple
Wondering Why a Fruit Fly was Born
The number of fruit flies
would be the only results.
The other choices are all
steps in the process
(Hypothesis, Experiment,
Observation).

would be the only results.
The other choices are all
steps in the process
(Hypothesis, Experiment,
Observation).
QUESTION 6:
What do you do to test a hypothesis?
Guess
Create a Spreadsheet with Data
Publish a Scientific Paper
Design an Experiment
You need to conduct a series of
procedures to test any
hypothesis. The developed
experiment uses variables
(changing factors) and controls
(unchanging examples).

QUESTION 7:
A control group is used as a comparison to
the group where things (variables) are
changing.
True
False
The control group of an experiment is a
group that is not experimented on. For
example, if you wanted to see what
happened when you increase UV radiation
on plants, you would have a control group
that did not have any different UV levels.
They would be used as a baseline or static
group in the experiment.

QUESTION 8:
An independent variable is a factor that
changes because of procedures conducted on
the dependent variable.
True
False
The opposite is true. A
dependent variable is a
factor that changes because
of procedures conducted on
the independent variable.
The opposite is true. A
dependent variable is a
factor that changes
because of procedures
conducted on the
independent variable.
QUESTION 9:
Experiments are usually conducted one time
and by one team to speed up the scientific
process.
True
False
Experiments are performed dozens and
hundreds to times before a scientific
statement is accepted as a truth. The
experiment would be performed using the
same procedures. To prove the original
hypothesis, the other testing team must be
able to generate the same results.

QUESTION 10:
Experiments often test multiple variables.
True
False
Experiments test for one
independent variable. There
can be multiple dependent
variables that change during
the procedures.
