1. what was the problem spongebob wanted to investigate?
2. what is the independent variable?
3. what is the dependent variable?
4. what should sponge bobs conclusion be?

Explanation:

1. SpongeBob's problem is based on his observation that his pants aren't as clean as before and his exploration of a solution (using a new detergent).
2. The independent variable is what is changed or manipulated in the experiment - here, the presence or absence of Clean - O detergent.
3. The dependent variable is what is measured or observed as a result of the change in the independent variable - the cleanliness of the pants.
4. The conclusion is drawn from the experimental result (pants with detergent not cleaner than those without).

Answer:

1. Does Clean - O detergent make pants cleaner?
2. Clean - O detergent (whether it is used or not)
3. The cleanliness of the pants
