In this activity, students have to find exact matches
to the five fingerprints on their experiment sheet.
|
Sometimes there are scratches
and dots in specific places on a
print that can be used to identify a
person. Lengths of lines and
placement of patterns also help in
the identification process. |
FINGERPRINT MATCH CARDS
|
Five of these fingerprint cards will match the fingerprints on experiment 5. Observe carefully and find reasons for your decision.
|
Police scientists carefully match fingerprints, first
by their patterns, but then they look even more
closely. Looking at the lines that make up the designs, these scientists find sections that are
specific to only that particular print. |
After careful
study, scientists
find points used
to identify a
particular print.
Scientists now
number and label
these points of
identification. |

Do the extra credit sheet below. Copy this sheet, bring it to another program and
print it out. Compare these prints to your fingerprint match cards in class. |
