5. Scientific method

6. IDENTIFY THE TERM
A question describing an experiment often written as “What is the effect of…?” or “What is the relationship between…?”

7. ANSWER
Problem—

8. IDENTIFY THE TERM
variables you change on purpose; also called the manipulated variable.

9. ANSWER
Independent Variable

10. Term…
After forming a hypothesis, scientists often do this

11. Answer
Test the hypothesis (design an experiment)

12. IDENTIFY THE TERM
The way(s) in which the independent variable is changed by the experimenter; these are the independent variables being tested.

13. ANSWER
Levels of the Independent Variable

14. Term…
After analyzing data in an experiment, scientist can then __ __

15. answer
Draw conclusions

16. IDENTIFY THE TERM
variable that responds to a change in the independent variable; also called the responding variable. It is what may be affected by the independent variable.

17. ANSWER
Dependent Variable—

18. IDENTIFY THE TERM
it’s a standard for comparison in an experiment. It’s often considered the “normal” condition in an experiment.

19. ANSWER
Controlled Experiment (control)—

20. IDENTIFY THE TERM
characteristics in an experiment that are kept unchanged in all trials. Factors that remain the same for all independent variable levels.

21. ANSWER
Constants

22. IDENTIFY THE TERM
number of times an experiment is repeated for each level, or value, of the independent variable. The more trials, the more reliable your results.

23. ANSWER
Repeated Trials

25. Identify the parts of experiment for the following problem
Is there a relationship between the number of cavities one gets and the amount of soda one drinks?
A. Independent variable?
B. Dependent variable?
C. Constants (2)
D. Suggested IV levels (3) and Control (based on suggested IV levels)?
F. Correct/incorrect: Hypothesis: If the type of soda is Coca-Cola then the number of cavities will increase.

26. Identify the parts of experiment for the following problem
Is a student’s ability to study (concentrate) affected by the type of music playing in the background?
A. Independent variable?
B. Dependent variable?
C. Constants (2)
D. Suggested IV levels (3) and Control (based on suggested IV levels)?
F. Correct/incorrect: Hypothesis: If the ability to study is better then the type of music will be classical.

A. Independent variable?
B. Dependent variable?
Constants (2)
Suggested IV levels (3)
Control (based on suggested IV levels)?
Correct/incorrect: Hypothesis: The phase of the moon will affect a dog’s behavior.

28. How does the height of the backboard effect the number of shots which get in?
A. Independent variable?
B. Dependent variable?
C. Constants (2)
D. Suggested IV levels (3) and Control (based on suggested IV levels)?
E. Correct/incorrect: Hypothesis: If the height of the backboard is taller than standard then the number of shots which get in will be greater.

29. Identify the parts of experiment for the following problem

A. Independent variable?
B. Dependent variable?
C. Constants (2)
D. Suggested IV levels (3) and Control (based on suggested IV levels)?
F. Correct/incorrect: Hypothesis: If the type of truck is small then the speed of the skateboard will be greater.
