Scientific Method
1. Formulate a question.
2. Research the question.
3. Form a hypothesis.
4. Conduct an experiment to test yourhypothesis.
5. Analyze data.
6. Draw Conclusions.
7. Communicate results.

The Hypothesis is the foundation ofthe experiment!
The development of a hypothesis is the first
step in designing and conducting anexperiment.
The hypothesis should be clear, specific, and
testable.

The Hypothesis
Is the prediction for the outcome of the
experiment.
States the relationship between the
independent and dependent variable!
Rememberyou are always testing to see if the Independent
Variable has an effect on the Dependent Variable.

The Hypothesis
Is written in the following format:
If the (Independent Variable) is (describe
change), then the (Dependent Variable) will
(describe change).
You must always use this Ifthen statement which stating
your hypothesis because is states the relationship between the
IV and the DV!

Heres a scenario for you:
Mr. Ponticelli tested to see if the amount ofTV had an effect on how many times his
baby woke up during the night!
He let JJ watch 1 hr, 2 hrs, 3 hrs, and 4 hrs
of TV.

Heres a scenario for you:
IV: TV time (1 hr, 2 hr, 3 hr, 4 hr)
DV: How many times his baby woke up duringthe night
HYPOT
HES
IS
:I
f the (amount of TV time) is(increased), then the (amount of times the
baby wakes up during the night) will
(increase).

Heres a scenario for you:
HYPOTHESIS: If the (amount of TV time) is
(increased), then the (amount of times thebaby wakes up during the night) will
(increase).
This hypothesis states the relationship between
the amount of TV time (IV) and the # of times
the baby wakes up (DV).

The Title of your Experiment
Like your Hypothesis, the title of your
experiment also has a specific format youmust use.
It also shows the relationship between the IV
and the DV.

The Title of your Experiment
Is written in the following format:
The Effect of(Independent Variable) on the
(Dependent Variable).
Remember, in your experiment, you are looking to see if the
IV has an effect on the DV.

The Title of your Experiment
Using the last example:
The Effect of(the Amount ofTV Time) on
the (Number ofTimes the Baby Wakes Up
During the Night).
Remember, in your experiment, you are looking to see if the IV
has an effect on the DV.

Effect vs Affect
Effect and Affect are great words to use
when writing Titles and Hypotheses.
Whats the difference?

Effect vs Affect
Effect is a noun. It refers to the outcome of an experiment.
It is ALWAYS used when writing Titles.
Affect is a verb. It means to influence or act upon something.

Ready for some practice?
1. Take out your Experimental Design sheet
with the vocabulary words.
2. Clear everything else off your desk.
3. Get a mini whiteboard, marker, and
eraser.

SHOW ME YOUR ANSWER!
1. Each group must give each student in the group aspecific number of 1-4.
2. I will put a scenario up on the screen.
3. Each group will discuss the scenario with eachother and identify your variables.
4. I will then call out a student number and a question
for you to answer. That student must write downthe answer though the teammates can help.
5. When I say Show me your answer, hold up yourwhite board for me to see.

Think about the following scenarios
Scenario #1:
Billy Bob set up an experiment to see if the
amount of sleep affects the reading scores
of 4th graders.

Scenario #3:
Sidney Crosby set up an experiment to
determine if the weight of a hockey puck
has an effect on the speed of his slapshot.
He measured his shot in mph.

Scenario #4:
Dr. Sawyer set up an experiment to see if the
amount of time students spend on
homework each night has an effect on their
Science MCAS score.
