A female butterfly lays eggs on a leaf to begin the butterfly life cycle. The eggs hatch into caterpillars, and caterpillars form chrysalises to change into butterflies. Students will follow a butterfly as it grows from an egg into an adult.

The life cycle of a frog takes place in water and on land. It begins in spring with a male frog croaking a song to attract a female. Young readers will read about and watch an egg develop into a tadpole and then into an adult frog.

Penguins must complete their life cycle in very cold temperatures. To protect their eggs from the cold, penguins use brood patches. Students will watch a penguin chick hatch from an egg and grow into an adult.

Male sea horses have a unique role in the sea horse life cycle. They carry the eggs and give birth to as many as 200 babies at one time. Young children can track a sea horse's life cycle from egg to fry to adult.
