Spirals
in Nature
The DNA molecule is twisted
into a double spiral, known as a double helix.
On this project we talked
about the spirals shown above and thought of other spirals in Nature:
· A snake's coil
· A snail's shell
· A hurricane or typhoon
· Water going down the plug-hole!
· A finger print (whorl)
· Hair growing from the crown on our heads
· Ringlets
· A pig's tail
· The inner ear (cochlea)
· A fern tendril uncurling
Can you think of any more?
