i need help with control and variables sheet with the spongebob and bikini bottom pals
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
wheres the answers!
iv: special juice
dv: group b
conclusion be: the juice made difference.
how be improved: wait longer.
inital observation: juice will get rid of slime
iv: coconut juicee

After 3 days of treatment, therwe is no change in the appearance of the green slime on either side of the shower.

Krusty was told that a certain itching powder was the newest best thing on the market, it even claims to cause 50% longer lasting itches.Interested in this product, he buys the itching powder and compares it to his usual product.One test subject (A) IS SPRINKLED WITH THE ORIGINAL ITCHING POWDER, AND ANOTHER TEST SUBJECT (B) was sprinkled with the experimental itching powder.Subject A reported having itches for 30 minutes.

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.
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.
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.
1. Control Group
2. Independent Variable
3. Dependent Variable
4. What should Smithers' conclusion be?
5. How could this experiment be improved?
you could also record this stiff on a bar graph that is wat mi teacher be sian
it could be improved by adding more people to the experiment and repeating it like 5 or six times
