2. Read the following scenario of a soda-pop experiment. Use the
information in the scenario to answer questions 2a-2g.
Nathan and Craig wanted to determine if ice made soda pop lose its fizz. He put 100ml of root
beer into each of 15 identical water glasses. To three of the glasses he added 1 ice cube each,
to the next three he added two ice cubes each, to the next three he added three ice cubes each,
and to the fourth set of three he added four ice cubes each. He used identical ice cubes. To a
fifth set of three glasses he added no ice cubes. Joe then measured the time it took for the root
beer to go flat or stop releasing bubbles.
2a. What is the independent variable?
2b. What is the dependent variable?
2c. What are the constants?
2d. Write a probable hypothesis being tested?
2e. Describe each of the levels of the independent variable being tested?
2f. How many repeated trials were conducted?
2g. State a control for this experiment?
