Identifying controls and Variables

Smithers thinks that a special juice will increase the productivity of workers. He creates two groups of 50 workers each and assigns each group the same task (in this case, they're supposed to staple a set of papers). Group A is given the special Juice. After an hour, Smithers counts how many stacks of papers each group has made. Group A made 1,587 stacks, Group B made 2,113 stacks.

Identify the:

Control Group

Independant Variable

Dependant Varriable

What Should Smithers' conclusion be?

How could this experiment be improved?

  9. the CONTROL is the normal situation that you compare your experiment to.

    The INDEPENDENT VARIABLE is something in the experiment that you control and change to see what kind of changes from the control can be observed

    the DEPENDENT VARIABLE is the variable that you measure in order to prove or disprove your hypothesis

  16. Homer notices that his shower is covered in a strange green slime. His friend Barney tells him that coconut juice will get rid of the green slime. Homer decides to check this out by spraying half of the shower with coconut juice. He sprays the other half of the shower with water. After 3 days of treatment, therwe is no change in the appearance of the green slime on either side of the shower.

    What are the different controls and variables?

  22. The control group is the normal situation that you compare your experiment to.

    The independent variable is something in the experiment that you control and change to see what kind of changes from the control can be observed.

    The dependent variable is the variable that you measure in order to prove or disprove your hypothesis.

    Answers are:
    1) Control group- Group B
    2) Independent variable- Special juice
    3) Dependent variable- Group B
    4) Conclusion- The juice made difference.
    5) How be improved- By waiting longer.

  23. Identify the Controls and Variables
    Smithers thinks that a special juice will increase the productivity of workers. He creates two groups of 50 workers each and assigns each group the same task (in this case, they're supposed to staple a set of papers). Group A is given the special juice to drink while they work. Group B is not given the special juice. After an hour, Smithers counts how many stacks of papers each group has made. Group A made 1,587 stacks, Group B made 2,113 stacks.
