Spiders have eight legs. Spiders
spin webs. The webs are made of silk.
Spiders spin webs so they can catch
insects for food. Spiders have eight
legs.
Spiders are called arachnids
(a-rak-nids). They are not insects.
Insects have six legs. There are more than 30,000 kinds of spiders. Some are
very, very small. Some are larger than a person’s hand. Spiders have eight
legs.
Spiders help people. They eat harmful insects, like grasshoppers and
mosquitoes. Spiders can live anywhere they can find food. One kind of
spider lives under the water. One kind of spider lives on Mount Everest, the
world’s largest mountain. Spiders have eight legs.

BUTTERFLIES & MOTHS
Butterflies and moths seem the
same, but they’re not. They both taste
with their feet. They look alike, too.
Butterflies and moths seem the same,
but they’re not.
Butterflies like to fly in the daytime;
moths like to fly at night. When they are
resting, most moths keep their wings open. Most butterflies rest with their
wings closed. Butterflies have large wings and thin bodies; moths have
smaller wings and larger bodies. Butterflies and moths seem the same, but
they’re not.
Butterflies and moths start life as tiny eggs. A caterpillar comes out of
each egg. The caterpillar eats a lot and grows very fast. The caterpillar
becomes a pupa (peu-pa). The pupa case hangs on a leaf. Inside the
case, the pupa changes into a butterfly or moth. When the butterfly or
moth is ready, the case breaks. The butterfly or moth comes out, and flies
away. Butterflies and moths seem the same, but they’re not.

I like to see giraffes at the zoo.
Giraffes are so tall they can look over
the tops of trees. Giraffes are so tall
they can eat the leaves off the tops of
trees. I like to see giraffes at the zoo.
Because giraffes are so tall, they
have a hard time doing some things,
like lying down. A giraffe has to tilt its body to one side, stretch one leg out,
and tuck its other legs under its body. I like to see giraffes at the zoo.
When a giraffe wants to stand up, this is hard, too. It pulls its neck back
and then pushes it forward to get itself on its front knees. It jerks its neck
again to push itself forward and raises its hind legs. It jerks its neck a third
time, and it is able to stand up. It is sometimes hard work to be a giraffe. I
like to see giraffes at the zoo.

I like to see hippos at the zoo.
Hippos look funny. They have small
ears, small eyes, and big bodies. The
hippos’s mouth is wide and deep.
Hippos have long teeth. Hippos have
short legs. The hippopotamus (hipp-o-
pot-a-mus) eats lots of plants. It eats so
many, it can weigh as much as ten thousand pounds! I like to see hippos at
the zoo.
Hippos eat on land, but the rest of the time they like to be in the water.
The hippopotamus is a good swimmer. It can dive for five minutes at a time,
and it can walk on river bottoms. I like to see hippos at the zoo.
Hippos like to live with other hippos, but they don’t like people very
much. This is why it is best for people not to get too close to them. I like to
see hippos at the zoo.

I like to see elephants at the zoo.
Elephants are the biggest animals that
live on land. Elephants have trunks.
Trunks are very long noses. I like to see
elephants at the zoo.
Elephants can touch things with
their trunks. They can push and pull
things. They can use their trunks to pick up food. I like to see elephants at
the zoo.
If an elephant thinks there is danger, it can sniff the air with its trunk. If an
elephant is angry, it can send air out of its trunk. That makes a loud sound. I
like to see elephants at the zoo.
Best of all, an elephant can use its trunk as a hose. It can suck up and
spray out water. It can drink the water, or it can give itself a shower. I like to
see elephants at the zoo.

Tarantulas (tar-an-tew-las) are very
big spiders. Tarantulas are very hairy
spiders. They have very big bodies, and
very strong legs. Tarantulas are big.
When tarantulas grow, they
outgrow their skins. As they get bigger,
they get rid of their old skin, and get a
new one. This is called molting (molt-ing). Tarantulas molt a lot before they
are all grown up. Tarantulas are big.
Tarantulas can live for a long time. They can live for as long as twenty-
five years. Tarantulas are big.
Tarantulas like to live under the ground. They come out at night to hunt.

There’s lots to know about lizards.
Lizards are cold-blooded. That means
their bodies can’t make heat, so they
must be warmed by the sun every day.
This is why lizards live where it is warm.
There’s lots to know about lizards.
Some lizards eat only plants. Some
lizards eat only insects. Some lizards eat both plants and insects. There’s lots
to know about lizards.
Some lizards have legs. Some lizards don’t have any legs. All lizards
have tails. Some lizards lose their tails, and grow new ones. There’s lots to
know about lizards.
All lizards move fast. Some are fast runners. The Slow Worm lizard
doesn’t run because it doesn’t have any legs. It still moves very fast, and it
looks like a snake. There’s lots to know about lizards.

strange. The armadillo is as big as a
cat, but it doesn’t look at all like a cat.
On its back and its sides, it has a coat
that is like stiff armor. Armadillos are
strange.
Its head is long and pointed. Its tail is long and pointed. On its feet, the
armadillo’s claws are long and pointed, too. It has four claws on its front
feet, and five claws on its back feet. Armadillos are strange.
The claws are good for digging a hole under the ground, which is where
the armadillo lives. The armadillo doesn’t see very well. The armadillo
doesn’t hear very well. Armadillos are strange.

Frogs and toads are amphibians
(am-fib-ee-uns). They have short, round
bodies. They have big heads and eyes
that bulge. Frogs and toads have no
tail, no fur, no feathers, no scales, and
no neck. Frogs have smooth, damp
skin. Toads are bigger, and most of
them have dry, bumpy skin. Frogs and
toads are amphibians.
This means they can live on land or in the water. Some frogs live in the
water all the time. Some frogs live in holes they dig in the ground all the
time. Some frogs live in trees all the time. Frogs have different feet for the
different places they live. Some feet have pointed toes for digging, while
others have sticky toes for climbing. Some feet have webbed toes for
swimming. Frogs and toads are amphibians.
Frogs begin life as eggs. When the eggs hatch, tadpoles come out.
Then, the tadpoles slowly turn into small frogs. This is called metamorphosis
(met-ah-mor-fuh-siss). Frogs and toads are amphibians.

horn right in the middle of their faces.
They have big heads and big bodies.
Their skin is thick and tough. It looks like
armor. I like to see rhinoceros at the
zoo.
Rhinos don’t see very well. They have one eye on each side of their
heads, so they can’t look at things that are right in front of them. That’s why
the rhinoceros turns its head from side to side and looks out of one eye at a
time. I like to see rhinoceros at the zoo.
Rhinos have very good hearing. They can tell where a sound is coming
from. They have a good sense of smell, too. They can smell things that are a
half mile away. I like to see rhinoceros at the zoo.
Rhinos make all sorts of sounds to each other. They grunt, they scream,
and they whistle. They can make a very low sound that humans can’t hear
at all. I like to see rhinoceros at the zoo.

their shape. I like the fun we have with
them. I like kites.
There are many different kinds of
kites. There are flat kites, and bowed
kites, and box kites, and sled kites, and stunt kites, and fighter kites. I like kites.
Kites can fly only when there is wind. A kite is held by its string so that it
pushes against the wind. At the same time, the wind pushes against the kite.
This keeps the kite in the air. I like kites.

A glider is a very simple kind of
airplane. It has wings, but no engine.
How does the glider fly?
The wings of an airplane have a
shape called an airfoil (air-foil). When
the wing moves, air moves around the wing. The airfoil is curved, so the air
going above the wing moves faster than the air going below the wing. How
does the glider fly?
Slow moving air has more power than fast moving air, so the air below
the wing is more powerful than the air above the wing. This power pushes
the wing up, and the glider flies. This is called lift. This is how the glider flies.

the airplane. They dreamed about
making an airplane that could fly. First,
they made large kites and gliders. They
tried to fly these kites and gliders, but
they didn’t fly very well. Then, in 1902,
Wilbur and Orville Wright built a glider that did fly well. Wilbur and Orville
Wright invented the airplane.
They built a motor to put on the glider. They built propellers to put on
the glider. In 1903 the airplane that Wilbur and Orville Wright built flew into
the air. It flew for only 12 seconds. It flew for 120 feet. They had done it.

The first helicopter flew in 1907. The
helicopter does not have wings like an
airplane. It has a rotor (ro-tor). A rotor is
the part of the motor that rotates (ro-
tates). This means it turns around and
around. A rotor on a helicopter has
blades. The blades are what go
around and around. The first helicopter flew in 1907.
The blades on a helicopter have an airfoil shape, just like wings on an
airplane do. As the blades go around, the air under them lifts the helicopter
up. The lift also helps move the helicopter in the right direction. The first
helicopter flew in 1907.
Helicopters can hover (hov-er). This means to “stay in one place”.
Helicopters can fly up or down. Helicopters can fly forward, or backward, or
sideways. The first helicopter flew in 1907.

This is how a car engine works. Gas
and air mix together and burn inside
the engine. The heat from the burning
gas and air turns into power (pow-er).
Power makes the car go. This is how a
car engine works.
The gas and air burn in a metal
container called a cylinder (cyl-in-der). Inside the cylinder is a piston (pis-
ton). A piston is a small cylinder with a metal rod that fits inside the bigger
cylinder. When the gas and air burn, the heat makes the air push on the
piston. When the piston is pushed, it moves a piece of metal called a
crankshaft. The crankshaft turns and moves the wheels of the car. This is
how a car engine works.
Most cars have a four-stroke engine. A stroke is one push of a piston, up
or down. In a four-stroke engine, the piston moves four times, over and over
again. This is how a car engine works.

How do you steer an airplane?
How do you make an airplane go up,
or down? How do you make it go to
the left, or to the right? To steer an
airplane, flaps are used. The flaps on
the wings are called ailerons (ail-er-
ons). The flaps on the tail are called
elevators (el-ev-a-tors). There is also a
rudder (rud-der) on the tail. How do you steer an airplane?
To go up, the pilot pulls the control stick back. This raises the flaps on the
tail, which pushes the air so that the tail drops. The nose goes up, and the
airplane goes up. To go down, the pilot pushes the control stick forward. This
lowers the flaps on the tail, which pushes the air so that the tail goes up. The
nose goes down, and so does the airplane. To turn to the right or left, the
pilot presses the pedals to move the rudder on the tail. He moves the
control stick to the side to raise or lower the flaps on the wings. The rudder
turns the airplane, and one flap goes up while the other goes down as the
airplane turns. This is how to steer an airplane.
