Introduction: The objective of this lab experiment was to determine the density of a set of plastic beads by using two different methods and decide which method was better. Density is a physical property that is defined as the ratio of an object’s mass to an object’s volume. Also density can be described as the measurement of how compact a substance is in a given space. To find an object’s density, it is necessary to measure the object’s mass, the amount of matter present, and volume, the space it takes up. Also when studying density, it is important to note how objects with varying densities behave. The density of water, at room temperature, is 1.00 g/mL and is often used to help determine the density of a substance based on if it sinks or floats in water. The measurement of the object’s density is important to the plastic company because it allows the company to make sure the product meets the design specifications. In determining the object’s density, the methods of displacement and floatation, were implemented. The first method used to determine the plastic bead’s density was displacement. Displacement is a method used to find density that is associated with the Archimedes’ principle, which states that when an object is submerged in a liquid, it will displace its’ volume. In this experiment, displacement was used to find the volume of a group of beads, which were small, multicolored, smooth, and round with a large hole in the centers. After finding the volume that the
