1. Demonstrate how
to use Zoomy for
the group. Have

3. Using a pencil, have each student heavily shade

Discuss the results by asking questions such as, What category has the most photos? Which category has the fewest? Do you think the results would be the same for other classes?
6. Have students complete the attached self-assessment.
Use students' graphs to assess their abilities
to gather and analyze data. Determine if students
were able to categorize the fingerprints. Use the
insight from the self-assessments to determine
student understanding. Are students restating
information that was shared? Are students able
to use this information to create something new?
Upload photos of different categories of fingerprints
and post them on your class website.
7. Challenge students to use the data from the experiment
to create a circle graph using a computer
program or pencil and compass. What percentage
of the class had each type of fingerprint?
