Lifecycle of a frog  by K23L students.
 On the water it floated,
A bubble of froth.
Within lots of black spots  ,
 A tiny tadpole came forth.
As his little black tail
Grew shorter and shorter,
His little black head
    Grew stronger and stronger

In and out among the weeds ,
He wriggled and he swam.
Soon two little legs
Came poking out,
And two little arms 
Began to sprout.
He found he could hop,
Leap, swim and float.
When he opened his mouth
Like a frog he could croak
And catch with his long tongue  Insects to eat!
