Symmetry in Nature

Extracts from this document...


Khan Salinder


.   A snowflake is an example of rotational symmetry.  When you rotate it 60 degrees you will find that the snowflake will still look the same as it did before it was rotated.  Or you can say that it has six lines of symmetry.  It can be folded in half in six different ways and both halves look the same.  Snowflakes can have either hexagonal or triangular symmetry although the hexagonal snowflake is most common.  



A beehive has translational symmetry meaning that it has a repeating pattern of hexagons.

Most animals are symmetrical in at least one way.  For animals, symmetry is related to fitness.   Symmetrical horses can run faster than non-symmetrical horses.  There are two types of animals; radiata and bilateria.  Radiata has radial symmetry.  Bilateria has bilateral symmetry.  Some advantages to bilateral symmetry are; easier movement, resistance to water, and efficiency to find food and to avoid and escape predators.



A mushroom is a type of fungus.  It has radial symmetry.  It can be rotated a fraction of

Here's what a teacher thought of this essay

This is a brief and very shallow investigation into different types of symmetry. It is framed using symmetry in nature as a context. The depth of the context needs to be developed more with statistical evidence to support the larger statements. There are specific improvements suggested throughout.
