My example of a fractal is a SNOWFLAKE. This is an example of a fractal because if you take away a fragment of the whole it looks just the same as the whole.

The video below explains how people we knew about fractals we would believe that math was present in nature/snowflakes due to symmetry, because the same pattern was viewed on both sides, so there was a complete balance.
