What are the dependent and independent variables in cleaning pennies experiment?
Independent variable: This is the one you're changing in the experiment, so it's the type of solution that you're dropping on the penny. Dependent variable: This is the one that you're measuring. In this case, it's how many drops you can get onto a penny without the water spilling off. Control variable: These are things that you keep the same throughout all of the experiments to make sure that your results are actually due to the changes in the independent variable, not some other random change you made. You used the same penny and dropper.

Is the variable alcohol when using water and alcohol to see how many drops can fit on a penny?
Yes, in this experiment, the variable "alcohol" refers to the liquid being tested to see how many drops can fit on a penny. By changing the type of alcohol used, you can observe how it affects the number of drops that can fit on the penny due to variations in surface tension and viscosity.

Is the oil discrete or continuous variable?
It depends. You might imagine situations in which you would need to add oil to a mechanism in drops. In such a situation you would not add 3.24 drops, you would add, say, 4 or 5 drops. In these situations the amount of oil would be discrete. On the other hand, the measure of the oil in a tank could be given to some considerable degree of precision. It would not be counted. In this case the amount of oil would be (effectively) continuous.
