Part 3  The Metric
Smile
Materials
Procedure
 Each person in your group will measure
and record the length of the smile of each other person in that
group.
 Make sure your results agree with
everyone else's. If there are discrepancies check your
measurements again.
 When accurate results are obtained
record them in the table from least to greatest.
Data Sheet
Assessment
1. Did any of your measurements agree with measurements of the
other groups? Which ones agreed?
2. Which method of measurement gave the widest range of
measurements?
3. What reason can you give for these differences in measurements?
