  • Ask each person to press their finger carefully on the ink pad, from the last joint to the end of the finger.
  • Remember to note whose print it is.
  • Compare the fingerprints. What can you see?

Can you see lines, creases and circles? Do any family members have similar fingerprints?

Can you make  chart of eye and hair colour for people in your family? Are they the same or different?

Some characteristics so run in families, but isn’t it amazing to think that we are all unique.
