DESCRIPTION
TRANSCRIPT
DEVELOPING A HYPOTHESIS AND TITLE FOR YOUR
EXPERIMENT
SCIENTIFIC METHOD
1. Formulate a question.2. Research the question.3. Form a hypothesis.4. Conduct an experiment to test
your hypothesis.5. Analyze data.6. Draw Conclusions.7. Communicate results.
THE FOUNDATION OF THE EXPERIMENT
The development of a hypothesis is the first step in designing and conducting an experiment.
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!
FORMAT
If the (independent variable) is (describe
change)
Then the (dependent variable) will (describe
change)
A SCENARIO
Mr. Joralemon tested to see if the amount of TV had an effect on how many times a baby wakes up during the night
He had his niece watch 1 hr, 2 hrs, 3 hrs, and 4 hrs of TV
THE EXPERIMENT
IV: TV Time (1 hr, 2 hr, 3 hr, 4 hr)DV: How many times his niece woke up during the nightHypothesis: If the (amount of TV time) is (increased), then the (amount of times the baby wakes up during the night) will (increase)
THE HYPOTHESIS
Hypothesis: If the (amount of TV time) is (increased), then the (amount of times the baby 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)
EXPERIMENT TITLE
Like your hypothesis, you also use a specific format on the title of your experimentYour title also shows the relationship between the IV and 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
A SCENARIO
Mr. Joralemon tested to see if the amount of TV had an effect on how many times a baby wakes up during the night
He had his niece watch 1 hr, 2 hrs, 3 hrs, and 4 hrs of TV
THE TITLE
The Effect of (the Amount of TV Time) on the (Number of times 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 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.”
SOME PRACTICE
1. Each group must give each student in the group a specific number of 1-4.
2. I will put a scenario up on the screen.3. Each group will discuss the scenario with each
other and identify your variables. 4. I will then call out a student number and a
question for you to answer. That student must write down the answer though the teammates can help.
5. I will call a team at random and check to see if you got it!
SCENARIO 1
Mayor Bloomberg set up an
experiment to see if the amount
of sleep affects the reading scores
of 4th graders
SCENARIO 2
Justin Bieber beliebes that all of his tattoos will make girls more attracted to himHe decides to test if the number of tattoos has an effect on how many girls approach him over the course of a year.
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. Frankenstein set up an experiment to see if the
amount of time student spend on homework each
night had an effect on their Science Regents Score
