Scientific Method Scenario
Background:

Task:
Write an investigative Question,
a Hypothesis, list the Independent Variable
to be tested,
and the Dependent Variable that will be
measured
Clem Clodhopper said,
Name It!
“I want to see if different colors of light help plants
grow better. I am going to take four plants
(all the same type) and set them up underneath four
different colors of light: white, red, blue, and green.
I will water them the same amount at the same time.
I will record how high each plant grows for two
weeks”

Pop – Pop - Pop
Ali’s favorite food is microwave popcorn. She
loves it so much that she can’t stand to see

tablets would still fizz in Sprite or Apple Juice.
1. Write a question, and hypothesis for Jason.
2. What would his independent and dependent
variables be?
Prove It!
It is well known that scientists around the
world prefer to use the metric system of
measurements.
In a paragraph, beginning with a topic
sentence, write three supportive sentences
explaining why this is so. Be sure to add a
concluding sentence to the end of your
paragraph.
What’s That?
In a freshwater environment,
populations of Daphnia (water fleas)
are almost all female. When the O2
level is low, or when food is scarce,
males are observed in greater
numbers. A researcher suggests
that male Daphnia develop because
of unfavorable conditions.
Which of the following would this be an
example of?
a. Result
b. Theory
c. Procedure
d. Hypothesis
Explain why….
