What is the Scientific
Method?
• It refers to the steps someone takes to…
1)
2)
3)
4)
5)
Identify a question
Develop a hypothesis (educated guess)
Design an experiment
Record observations
Make a conclusion
In other words.. it’s a way to solve a
problem!
Scientists think
carefully and
logically when they…
(1) investigate a
question or
problem.
Ex: What is in this box?
Scientists develop a question,
gather information and…
(2) form a hypothesis-- an
educated guess.
Ex: If the object inside
the box is bouncy and
rolls around, then it is
a superball.
Writing a Scientific
Hypothesis:
If…, Then…
Ex: If the check is for Auto Body
Shop, then she went to go fix her
car.
The next step scientists
take is to… (3) create and
conduct an experiment
to test their hypothesis.
Ex: Move the box side to
side to see if the object
is rolling or sliding.
A key to experiments is…
(4) observing what happens
and writing it down.
Ex:
Box#
Observations
Object
Note: There are 2 types of
observations!
(4a) QuaLitative
Observations are
based on Looks!
Color, shape, size, texture can
be used to make observations.
Ex: The ball is small and rubbery.
(4b) QuaNtitative
Observations are
based on Numbers!
Make these observations by
counting or measuring with a
tool (ruler, scale, etc.).
Ex: The metal pipe weighs 5 grams.
Ex: There are 12 checks.
Make 1 quaLitative
observation and 1
quaNtitative observation:
Note: Gathering information or
data and recording it so it is
readable and makes sense to
others is really important.
Don’t be a mad scientist!!
Once a scientist completes an
experiment, they will…
(5) repeat the experiment to
see if they get the same
results.
This is called verification-checking things out to make
sure everything was correct
and the results will be the
same over and over.
Scientists also need to…
(6) share their experiments
and conclusions with others.
Because they share their experiments
and findings, scientists can learn from
each other and often use someone
else’s experiences to help them with
what they are studying or doing.
The steps of the Scientific
Method are:
•
•
•
•
•
•
Question
Background Research
Hypothesis
Procedure (Experiment)
Data (Observations)
Conclusion
Make 1 quaLitative
observation and 1
quaNtitative observation:
Graphing Preassessment!
Directions: Create a line graph
based on the below data. Include
all elements of a proper graph.
You will be given 5 minutes.
How do you perform a
scientific experiment?
Independent Variable:
CHANGED in
the 1 variable that is ___________
an experiment
Dependent Variable:
MEASURED
the 1 variable that is ______________
in an experiment
The Title is Always…
The Effect of ____________on ___________
Independent
Dependent
The Effect of
SOIL TYPE
______________
on
PLANT HEIGHT
______________
Experimental And Control Groups
In order to test something,
must have a comparison.
we
- Experimental group: one being tested
- Control group: comparison to the
experimental group
Experimental And Control Groups
In an experimental and control group, only the
independent variable is changed.
Medicine example - clinical trials (placebo)
Warm Up – September 3, 2015
