1. Graph Info for Labs: In your lab book: For Lab Report:
Sketch the graph (title, labeled axes, general trend shown)
Write equation describing linear fit (substitute appropriate variables and include units for slope and y-intercept)
For Lab Report:
Autoscale graph from Zero (0,0 origin)
Check point protectors in graph options
Uncheck connect points in graph options
Copy and paste graph to a Word Document and Save

2. Linear equations for Scientific plots:
Start with generic y = m x + b
Replace y, and x with chemistry variables from the graph axes; replace m and b with values from analysis of graph for slope and intercept.
What are the numbers missing?
Add Units!!!

3. Linear equations for Scientific plots:
Decide if b (y-intercept) is significant:
5% Test:
(Y-max = largest y value from data table)
Rule: if intercept is less than or = 5% of max Y value, the intercept is negligible and you may drop it from the equation;
if intercept is greater than 5% of max Y value, it is significant and you must keep it as part of the final equation.
Write the final equation of the line

4. Percent Error How far off the results are from the actual value
Percent error = |observed – actual| X 100
actual

5. Mass & Volume Report Experimental Background
Complete all sections

6. Mass & Volume Report Data Collection: Data Processing
Include Quantitative data you took as a group (RAW data).
Include Qualitative data
Use titles and headings! (include units and uncertainty)
Precision will be checked for.
Data Processing
Table with class data (indicated in title) for your metal only
Graph class data of only your metal (not both)
Line of best fit
Include equation under the graph and discuss it in the conclusion.
% error calculation

7. Mass & Volume Report Conclusion
Make conclusions based on results. (i.e. what trend does the graph show? What relationship exists? How was it modeled?)
Explanation/Justification: What does the slope of the line mean? What is it called? Was your slope value too high? Too low? Explain!

8. Mass & Volume Report
Evaluation (very important!) – make two paragraphs following the conclusions
Identify the limitations of the procedures and materials
Discuss how these limitations affect the results
How could these things be improved to better the experiment?
