Pre Lab: Background: The Density of a material may be determined by determining the mass and volume of a sample material and calculating the mass/volume ratio. An independent variable is the variable that is being manipulated or changed during the experiment. The dependent variable is the variable that is being measured. The independent variable for this experiment is the copper because you are only changing the amount of copper you use. The dependent variable is the density because we are measuring

identify which substance is which is to calculate the densities. To do this‚ one must take the mass and volume of each individual substance. Starting with mass‚ one can use the triple beam balance. Make sure the balanced is zeroed. Once that is true‚ place the object onto the balance a carefully find the mass of the object. Repeat and record the results found of each individual substance. To find the volume‚ one can use the water displacement method. One will fill up a graduated cylinder with water to a
