of film. To make the images move
smoothly, 24 frames are needed for every
second of film.
Filmmakers can also create animation
with figures made of clay or other materials.
Instead of drawing thousands of
images, they take many photographs of
figures set up in a scene. They move the
figures slightly between each photograph.
This technique is called stopmotion
animation.
Computer Animation
Computers have made animation a
faster process. They can produce the
To create an animation an artist draws the
same character many times. In each drawing
the character has changed position
slightly.
Artists used computers to make

thousands of pictures needed for an animated
film more quickly than human
artists. Artists can also use computers to
create characters, objects, and backgrounds
that look more real than drawings
do. Today computers are used in
almost all animation.
Computer animation can be used to
make a whole movie or to create special
effects in live-action films. Many spacecraft,
robots, and monsters in movies are
actually computer images.
Computer animation can be used for
more than just entertainment. Scientists
use computer animation to show things
that people cannot easily see in real life.
Such things include the movement of
the solar system, weather patterns, and
the inside of the human body.
History
In the 1800s people invented spinning
machines that made a series of drawings
appear to move. The first animated films
appeared in the early 1900s. Walt Disney
made the first animated film with
sound, SteamboatWillie, in 1928. In
1937 Disney made Snow White and the
Seven Dwarfs. It was the first full-length
animated film to be released as a major
motion picture in the United States.
Animated television shows appeared in
the United States in the 1950s. Toy
Story, from 1995, was the first long film
made completely with computer animation.

Ant
Ants are social insects. This means that
they live together in organized communities
called colonies. There are more
than 10,000 different species, or kinds,
of ant. Ants are found almost everywhere
in the world, but they are most
common in hot areas.
Ants range in size from 0.08 inch to 1
inch (2 to 25 millimeters). They are
usually yellow, brown, red, or black. The
body of an ant is divided into three sections:
the head, the thorax (midsection),
and the abdomen. The head is large, and
the abdomen is slender and oval. The
thorax is connected to the abdomen by a
small waist. Two antennas are located on
the top of the head. Ants use their
antennas for guidance, smell, and communication.
Most types of ant live in nests that they
make from many different materials,
including soil, sand, wood, and leaves.
Some ants build anthills.Within each
nest there is usually a queen, workers,
and soldiers. The queen spends her life
laying eggs. The workers are females
