Joseph Leonard Steven Doyle Green H 11/21/08 Density Lab Purpose: The purpose of this lab was to demonstrate different methods of measuring density both in regular and irregular objects. Data: Density Formula – D = M/V Observations: • The domino had 12 dots. • The dots on the domino are carved into the domino, which changes both the mass and the volume of each of the different numbers on the dominoes. • The formula used to calculate the volume of the domino is the volume formula for a rectangular prism. The domino is not a perfect rectangular prism because of its divots and rounded edges, which causes the volume to be not perfectly accurate. • The curves and angles of the gummy bear made it impossible to get accurate data by trying to measure it with a ruler. • The gummy bear sank, which makes sense because its density is greater than that of water (1g/cm³) Conclusion: Density is easily calculated by using the equation D=M/V. Before calculating the density of an object, you must first find the mass and volume.
