Question

SpongeBob noticed that his favorite pants were not as clean as they used to be . His friend Sandy told him that he should try using Clean-O detergent, a new brand of laundry soap she found at Sail-mart. SpongeBob made sure to wash one pair of pants in plain and another pair in water with the Clean-O detergent. After washing both pairs of pants a total of three times,the pair washed in the Clean-O detergent did not appear to be any cleaner than the pants washed in plain water.

6.What was the problem SpongeBob wanted to investigate?
7.What is the independent variable?
8.What is the dependent variable?
9.What should SpongeBob's conclusion be?

Answer 1

6. Spongebob wanted to see if Clean-O would clean his pants thoroughly.
7. Type of detergent
8. How well Clean-O worked
9. That using Clean-O laundry detergent mixed with water to wash his pants is comparable to washing his pants without the use of Clean-O because they seem to have the same impact. Clean-O is not effective.
