Children are naturally curious about the world around them, and
curiosity is a powerful motivation for reading. Information books
like this one allow you to feed your childrens interests and create
readers who not only can read but
want to read! Interesting informational books such as the National Geographic
Readers help your children learn more about the world we live
in, while helping them with reading comprehension. And stud
ies show that informational reading is critical to success as they
progress through school. With the earliest levels in this series, you and your children will
want to read together. Even after your children can read alone,
theyll still enjoy reading time with you. Either way, keep in mind
that when parents show that reading is fun, rather than a set of
skills to be learned, their children achieve more, and learn more.

What is quick? What is quiet? What has five rows of teeth? What glides through the water? CHOMP! Its a shark! Sharks live in all of Earths oceans. They have been here for a long time. Sharks were here before dinosaurs.
CARTILAGE:Cartilage is light, strong,
and rubbery. The tip of your noseis cartilage.
Can you feel how soft it is? Shark tail fins are larger on top. This helps them move through the water better. A shark is a fish. But a shark is not like
other fish. Sharks do not have bones.
They have soft cartilage instead. Cartilage
helps sharks twist and turn.
Cartilage helps
sharks move and bend.
If a shark loses a tooth, a new one
moves forward to take its place. Shark skin feels bumpy and rough. Its
hard like sandpaper. It protects sharks
and helps them swim faster.
Shark babies are called pups.
Some pups grow inside their mothers. Other pups hatch from eggs.
What do you call a shark baby
from the Arctic? Lemon shark pups grow inside their mothers.
The lemon shark mother goes to shallow water to give birth. The pups stay near the
shallow water until they are grown. These fish are called remoras.
They hang around sharks and eat
their leftovers. A
pup- sicle!
Swell shark pups hatch from eggs.
The
mother sharks lay the eggs in hard cases.
People call the case a mermaids purse. Swell shark mothers lay up to five egg
cases at a time. In nine months, the swell
shark pups are born. A pup coming out of its egg case.
PREDATORS: Animals that eat other animals.PREY:Animals that are eaten by other animals. When shark pups grow up, they are
awesome predators.
Sharks can see better than humans can.
Sharks can see better than humans can.
Even in deep, dark water, a shark can see its prey. Sharks take a test bite of prey before eating. Their taste buds tell them if the prey is fat
enough to eat.
What is a great whitesfavorite candy? a
jaw breaker.
