Stonesifer 1 Introduction: In this experiment we were trying to use mass and volume of an object to find its density. By taking metal pieces and first measuring their weight in grams though the use of an electric scale, and then measuring their volume in two ways, we can accomplish this task. In order to find out the volume of the metal pieces we used water displacement and then used another method, measuring height with a ruler then using the formula r , we found the volume. Using the formula Density = Mass/Volume, we were able to acquire our data for use in graphs showing that the mass of an object is directly proportional to the objects volume. Data and Observations: Piece 1 Piece 2 Mass (g) 10.504 33.736 Volume with water method (mL) 1.5 4 Volume with ruler method (cm 3 ) 1.244 4.298 - For water displacement we started with 15ml of water in a graduated cylinder then
