This document provides instructions for calculating the density of different metal blocks through measuring their mass and volume. Students are directed to find the mass of each block using a balance and then measure its volume by finding the displacement of water in a graduated cylinder. They then calculate the density of each block by dividing its mass by volume. The procedure is repeated multiple times for accuracy and repeated for additional blocks to compare densities.

1. Density of Metals Aim To be able to calculate the density of a metal by measuring the volume and mass.

4. Method Find a flat place to work near a sink. Use the balance and record the mass of the block (g). Fill a Eureka can with water. Put a graduated cylinder below the spout of the Eureka can. Put the block in the Eureka can. Try not to spill or splash and water. Measure the water in the graduated cylinder. Calculate the volume of the block. Calculate the density of the block. Repeat this procedure 2 more times. Repeat steps 1-9 for the other blocks.

5. Method: measuring mass and volume Take the mass of the block (g) using a scale and recode it in a table. Fill a Eureka can with water and let it empty out until it stops dripping. Put the block into the Eureka can and catch the displaced water using a measuring cylinder. Record the volume of displaced water (ml). Calculate the density of the block by dividing mass by volume Repeat the test 2 more times for this block. Repeat steps 1-6 for the other blocks.
