Scientific Method/Measurement Review and Study Guide
I. Scientific Method. Matching – use the words below to fill in the blank
with the matching definition.
observation
hypothesis
problem
experiment
research
conclusion
WORD
DEFINITION
Refers back to the hypothesis and compares results.
Describes what you learned and didn't learn. Tells
whether you hypothesis was supported or not
supported.
Information gathered from books, the internet and
other resources about the experiment.
An educated prediction using the If ______ then
_____ because ______ format.
The step that states a question about what you're
going to experiment on.
The step that describes by using your 5 senses and
recording what you see/measure in an organized
way.
A detailed list of materials and instructions on how
to test your hypothesis.
6. __________________________

scientific method in order.

III. Label the examples of each step of the scientific method correctly.
(hypothesis, conclusion, problem, observation, experiment, research)
7. _________________ The scientists writes, "Therefore I suggest that my
hypothesis was supported because the salt water freezes at a lower temperature then
the fresh.
8. _________________ A scientist wants to find out: Does sea water freezes at a
lower temperature than fresh water?
9. _________________ The scientist creates a list that includes, 2 beakers, 2 liters
of water, 70 grams of table salt, refrigerator. Then the scientist does the following
in the laboratory:
1. Fills 2 beakers each with 1 liter of fresh water
2. Dissolves 35 grams of table salt in one of the beakers.
3. Places both beakers in a refrigerator whose temperature is -1 C.
4. Leave s the beaker in the refrigerator for 24 hours.
10. __________________ My prediction is that if I put a beaker of freshwater and
a beaker of saltwater in the freezer then the freshwater will freeze first.
11. __________________ The scientist used information from prior experiments
and from books on salt water and freshwater to gather information for his
experiment.
12. ___________________ After 24 hours in a freezer set at 32°F the scientist
examines the both beakers and finds the fresh water to be frozen. The salt water is
still liquid.
IV. Experimental Design. Vocabulary Matching.
Constant
variables
independent variable
repeated trials
control
dependent variable
WORD
DEFINITION
The standard for comparison in an experiment.
Things that can be changed in an experiment-any changes
in an experiment.
The variable that is changed on purpose by you.
A term that means you have the same amount of water,
same containers, etc. in an experiment -- things that stay
the same during the experiment.
The variable the responds to the change in the experiment.
You have no control over this variable.
The number of times to experiment is done over again.

VI. Variables
Read each statement & identify the independent and dependent variable.
A. Mandy put a gummy worm in water overnight. The next day she observed that the
mass of the gummy worm changed.
Independent __________________________________________________________
Dependent ___________________________________________________________
B. Erik timed how fast 3 items, a feather, a marshmallow, and a balloon, fell to the
ground when dropped from the same height. He recorded the times for each using a stop
watch. He then recorded his data on a graph.
