DENSITY OF SOLIDS LAB - Orange Board of Education



DENSITY OF SOLIDS LAB

Equipment Needed:

Triple Beam Balance Scales

Electronic Scales

Graduated Cylinders

Density Specimens

Calculators

Water

Rulers

Purpose:

This lab emphasizes analytic measurements, experimental technique, and problem solving, in determining measurements. You will determine the mass and the volume of given materials to find their density: DENSITY = MASS / VOLUME Volume of Rectangle = L x W x H

Method:

You will be placed into groups to perform this experiment. You will find your equipment at each of your workstations. To find the density, you will need to measure mass and volume. If your specimen has smooth, measurable sides, (like a block) measuring with a ruler to find the volume will be the most accurate (V = L x W x H). Otherwise you will need to find the displacement of the object to measure its volume. Be as accurate as possible.
