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.
