Density Lab Report Objective: To measure the density of different materials. Materials: 400 mL Beaker Ruler Water Triple Beam Balance Box of Density Cubes Goggles Tongs Procedure: 1. Put on all safety equipment and gather all materials. 2. Create a chart (A) in your data section with three columns. 1st column with the name of each of the density cubes. 2nd column with your guess on if the cube will float in water. 3rd column with the actual results. 3. Before putting each cube into a 400 mL Beaker of water guess if it will float or sink. Then test this hypothesis by putting the density cube in the water. Record your results. Remember to dry off the cubes once you get them out. 4. Create a chart (B) in your data section with 7 columns; see data section for how to create it specifically. 5. Weight each cube on the Triple Beam Balance and record its Mass. 6. Measure the length, width, and height of each cube. Find the cube’s volume by multiplying the length x width x height and record it on the chart. 7. To find the density of the cube you must divide the mass by the volume. D = m / v 8. Once all calculations are done answer the conclusion questions. 9. Clean up your area and put away your materials. 10. Take your lab notebook home this is the first formal report.
