Density Lab

Purpose:     To perform an experiment that will determine the density of the following: Wood
Cube, Aluminum Cylinder, Antifreeze, and an odd shaped object.

Theory:      Density equals mass divided by volume.

Procedure:

Part A    Wood Block

1.     Measure the mass using a triple beam balance scale. Create a Data
Table and record with last digit estimated.

2.     Measure the length, width, and height. Record with last digit estimated.

3.     Calculate the volume showing all of your work. Record in data table.

4.     Calculate the density showing all of your work. Record in data table.

Part B    Aluminum Cylinder

1.     Measure the height and diameter. Record with last digit estimated.

2.     Calculate the volume showing all of your work. Record in data table.

3.     Measure the mass using a triple beam balance scale. Record with last
digit estimated.

4.     Calculate the density showing all of your work. Record in data table.

Part C     Antifreeze

1. Measure the mass of a graduated cylinder. Record with last digit estimated.

3. Measure the new mass of the graduated cylinder.

4. Calculate the mass of Antifreeze added and record.

5. Record the volume of Antifreeze in the graduated cylinder.

6. Calculate the density showing all of your work.

Part D Odd Shaped Object

1. Measure the mass of the odd shaped object. Record with last digit
estimated.

2. Fill a displacement container with water.

3. Hold graduated cylinder under spout and gently place the odd shaped object
in the container. Record the volume of water displaced.

4. Calculate the density showing all of your work.

BELOW IS THE DATA TABLE FOR PROCEDURE A. YOU MUST CREATE PROPER DATA TABLES FOR
PROCEDURES B – D.
