1. How to Start your Lab Report
CHEMISTRY NAME ________________ EXPERIMENT NUMBER #3 SECTION DATE SEARCHING FOR REGULARITY NAME(S) OF LAB PARTNER(S)

2. Searching for Regularity
Objective: To observe mathematical and graphical relationships between mass and volume

3. Procedure: Mass a metal object to the nearest 0.01 g.
Fill a graduated cylinder to the 30.0 ml mark with water.
Carefully add the metal object to the water and record the water displacement.
Record data on your data table.
Repeat these steps for the other metal objects.

4. Procedure Obtain mass and volume data from other members of the class.
Plot average mass and volume. Record mass along the vertical axis and volume along the horizontal axis. Give the graph a title.
State the regularity and propose an explanation for what you observed on your graph.
Draw lines to represent the mass-volume relations.

5. Data: Collect mass and volume in a chart, similar to the following :
Object #
Volume of water and object (mL)
Volume of Water (mL)
Volume of Object
Mass of Object 1 2 3

6. Data: Obtain mass and volume data from other members of the class.
Plot average mass and volume. Record mass along the vertical axis and volume along the horizontal axis. Give the graph a title.

7. Conclusion:
Propose an explanation for what you observed on your graph.
