Purpose: How does density change as you move down a family on the periodic

table?

Materials:

Lead Shot 10-ml graduated cylinder

Tin Shot 50-ml graduated cylinder

Silicon pieces Balance

Carbon Weighing dishes

Procedure

1. Determine the mass and volume of each sample. Record in your data table.

2. Calculate the density of each sample.

3. Graph density vs. period number for your samples.
