Animals’ life stories Life is like a story. It has a beginning, a middle, and an end. Babies are born or eggs hatch. That is the beginning of an animal’s life story.
Babies come in all shapes and sizes. 4
Humans are animals, too.
A horse eats hay and grass to help it grow.
eating All animals eat and grow. Some grow slowly and some grow quickly. All animals — even humans — grow.
Milk will help this boy grow big and strong. 7
growing Children grow to be adults. When they reach adulthood, they may resemble their parents.
A mother with her daughter 8
It’s fun to measure how much you are growing.
learning Most animals learn as they grow. They may learn simple things like how to get food.
This margay has to hunt for its food.
Humans can buy their food at a store. 11
All humans change as they grow.

14
Humans teach other humans.
working and playing Most animals spend their waking time looking for food. That is their life’s work.
16
Most humans have time to play and work.
Some humans work on farms.
Some humans work in factories.
17
reproducing All animals reproduce. When they become adults, they lay eggs or have babies of their own.
Baby chicks hatch from eggs that hens lay. 18
Having young makes sure that their species survives. Animal species that do not live to reproduce become extinct. Dinosaurs are extinct.
20
growing old All humans grow old. Their life story will come to an end. A grandfather sits with his grandchildren.
21
Every animal species has a life span. A life span is the largest number of years that each kind of animal could live.
