Life CyclesClick on the underlined words to view the
life cycle of that organism.
Humans Butterflies
Crickets Frogs
ChickensElephantsOak Trees
HumansHumans are born as babies
As babies grow and change, they become children
Children continue to grow and change into adults
Over time adults age and continue to change
Over time humans do change – they get
bigger as they get older – but they
don’t go through any really big
changes – like growing new arms or wings.

Butterflies begin life as an egg

ButterfliesCaterpillars hatch out of eggs and begin eating plants
Out of the caterpillar comes a winged butterfly
As the caterpillar ages it begins to change. It spins a cocoon where it begins to make large changes
Butterflies go through big changes
during their life cycle.
Crickets are hatched from eggs but from birth look very similar to the adults. They do not go through a big change.

Frogs begin life as eggs

FrogsThe eggs hatch into tadpoles
Over time, the tadpoles grow legs and start to breath air
Finally, the legs grow and the tail shrinks
Frogs, like butterflies, go through
big changes during their life cycle.
Chickens begin life as an egg

ChickensWhen the chick hatches it is covered in soft feathers and cannot flyAs the bird
becomes an adult it becomes larger and the feathers change
Chickens, like humans, go through
small changes during their life cycle.
Elephants do not change much as they go through life. They get bigger, the males
grow tusks. But the adults look very much like the young.
