Fingerprint Patterns
Scientists when looking at fingerprints try to sort them into groups. They usually sort
them by looking at the pattern that the ridges (lines) of the print make. Look at your
own fingerprints and see if you can decide which of the following they are.
Loops
In a loop; the lines in a print enter from one side, go
round the middle of the print and then leave on the
same side that they entered.
Arches
In an arch; the lines in a print enter from one side
rise up in the middle and then leave on the
opposite side to that which they entered.
Whorls
In a whorl; the lines in a print turn through a full 360° making a circle, or a spiral. There
are several different types of whorls.

Activity Instructions
Step 1: Each of the print cards has a specific layout and
details that must be filled out, put your real
details or make them up.
Step 2: Two people out of each group will take each
others prints first and the rest will carry on filling
in the worksheets. The person not having their
prints taken should wear gloves.
When taking the prints you should demonstrate how
they may find it easier if they fold the fingerprint form
along the suggested lines when they are taking the
appropriate prints and place the form along the edge of
the table.
Step 3: The pupil wearing gloves will take the prints of
the other pupil. Practise taking prints onto the
newspaper on the desk before using your
fingerprint form until you are happy you are not
using too much ink. Starting with the left thumb;
the thumb is rolled in the ink pad covering the
thumb in ink from nail edge to nail edge and
then rolled onto the print card, again from nail
edge to nail edge.
Step 4: Repeat step 3 for the rest of the fingers on the
left hand and then the right hand. Then WASH
and DRY your hands and switch with your
partner.
Step 5: Once you have both finished let two more
people out of the group start taking their
fingerprints, you should then make sure you
have completed the questions before you begin
your analysis.
