Which is the independent variable and the dependent variable?

In this experiment:



I'm doing an experiment to test how the size of a pot affects the rate at which water boils. The flame on the stove and the quantity of water are the same. The differences in the sizes of the pots are the height of the pot and the surface of the bottom of the pot. I am keeping track of the time (in minutes) of how long it take the water to reach a temperature of 212*F.



In this experiment, which is the independent variable, which is the dependent variable, and what are the constants? I always get sooooo confused, so help is appreciated. THANK YOU!Which is the independent variable and the dependent variable?
IV: The height and surface area of the pot

DV: How long it takes the water to reach 212 F

Constants: The amount of water used and the heating mechanism



If you ever get confused just explain it out loud to yourself.

For example: How soon the water reaches 212F is DEPENDENT on the size of the pot.



And the constants are the things you don't change throughout the experiment.



You should also have a control, but I've been out of the sciences for a while so I'm not exactly sure how you should set that one up. Possibly set up too additional size and surface area as your experiment pots.Which is the independent variable and the dependent variable?
I think the independent is (what you change for the experiment) the size of the pot, (surface area and height and that) and the dependent (what changes as a result of you changing the independent) is the time it takes the water to reach the 212*F. Science is the freaken worst subject goin round but for some reason i remember that... Oh and the constants remain the same during the experiment so they are like the outside temperature, the type of water (is it diluted etc), the material of the pot. They all have to be controlled for you to have accurate results.Which is the independent variable and the dependent variable?
Independent variable is the size of pot. Dependent variable is the rate at which water boils. Because it's always INDEPENDENT affecting DEPENDENT.



There are many constants though, but they will usually ask you only 2 in exams. In this case, the constants are: Time taken(in min) for water to reach 212F and the strength of the flame
