1. Honors Physics Lab Journals Graphing

2. Lab Journal Entries  Number pages in consecutive order  Date all entries  Title all activities and investigations  Identify group members  Identify independent and dependent variables  Identify control variables

3. Lab Journal Entries  Write a testable hypothesis or Statement of Problem  Write a procedure summary including a list of materials and equipment  Construct an appropriate data table.  Make detailed notes during the investigation  Record all observations  Note any occurrences that may have an effect on the investigation

4. Lab Journal Entries  Include all pertinent plots, graphs and diagrams  Summarize any other important information.  Record Preliminary Findings

5. Graphing  All scientific graphs must include the following information  Title clearly stating the purpose of the graph and the independent and dependent variables  Independent variable plotted on the horizontal axis  Dependent variable plotted on the vertical axis  Axes clearly labeled with appropriate variable named, units of measure and scale.  Best Fit line or curve that represents all of the data

6. Graphing with Microsoft Excel  Open a new document  In column A, type data for independent variable  In column B, type data for dependent variable

7. Graphing with Microsoft Excel  Click on the Chart button in the toolbar  Choose XY Scatter  Use the default type  Click NEXT  Type in the title for the graph and label the axes  Click FINISH
