i am doing a lab trying to find the density of a snickers bar and a 3 musketeers. i am using a snickers, 3 musketeers, triple beam balance, and ruler. what is the independent variable in this experiment? and the dependent variable? i think the dependent variable is the density. what about the controls? thank you! p.s. if u could give me the procedures for the way i would do this experiment would be nice too.

The usual way of finding the density of an object is to divide its mass by its volume.
The volume of an irregular object is usually found by displacement.
Placing candy bars in water will probably dissolve them, so I suggest that you use very cold water.

density = mass / volume
Weigh the candy to find its mass
Measure its length, width, heigth to get its volume
Then divide
(If the density is less than 1 gram/cubic centimeter, it will float in water.)
