This site is geared more toward a consumer than a student, but it does list, describe, and in some cases compare each of the primary identification methods (fingerprints, iris recognition, voice, etc).

In this activity, students will create a class quilt of nine patch paper quilt blocks using geometry.

This interactive activity gives you an opportunity to color in a tessellation that is different from the usual. Read the short introduction to find out more about this tessellation that doesn't repeat.
