A. observation B. hypothesis
E. experiment F. research
C. problem
D. conclusion
1. ______ 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.
2. _____ Information gathered from books, the internet and other resources
about the experiment.
3. _____ An educated prediction using the If I do ______ then _____ will
happen.
4. _____The step that states a question about what you're going to experiment
on.
5. _____ The step that describes by using your 5 senses and recording what you
see/measure in an organized way.
6. _____ A detailed list of materials and instructions on how to test your
hypothesis.

(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, dependent variable,
repeated trials, control
13. ________________________________The standard for comparison in an
experiment.
14. ________________________________ Things that can be changed in an
experiment-any changes in an experiment.
15. ________________________________ The variable that is changed on
purpose by you.
16. _________________________________ 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.
17. ________________________________ The variable the responds to the
change in the experiment. You have no control over this variable.
18. ________________________________ The number of times to experiment is
done over again.
