Title: Graphing Practice: The Relation of Atomic Number and Atomic Mass

Purpose:

• to practice graphing
• to determine the relation of atomic number and atomic mass

Materials:

• periodic chart
• ruler
• pencil
• graph paper

Procedure:

1. Graph atomic number (x) vs atomic mass (y) for elements 1~85
2. Draw a line of best fit
3. Determine the slope of the line
4. Determine the percent error (get actual value from Mrs. Nuño)

Results: This will be your graph

Analysis & Discussion:

• Summarize what you did
• Describe the pattern
• Discuss what the slope means

Conclusion:

• a one sentence testable statement
• relate the atomic number to the atomic mass

Reflection:

• personal comment
