Dolphins
Dolphins are marine mammals. They must
breathe air in order to survive. They
belong to the Delhinidae family. Dolphins
have velvety skin. Only newborn dolphins
have a few bristly hairs on their snouts.
The hair quickly falls out. They have a long
tail and a fin on top of their backs that
prevents them from rolling over. When
female dolphins dive deep, they have a
thick layer of fat under their skin to keep
them warm. Flippers are the dolphin's front
fins. They use them to make left and right
turns. Dolphins can reach lengths of 2 to 3
meters and weigh up to 75 kilograms.
Dolphins hunt in large groups. A "pod" is a
group of dolphins. Fish, shrimp, and small
squid are among their favorite foods. They
live in saltwater oceans. When dolphins
hear or see a shirr nearby, they approach it
and follow it for several kilometers.
Dolphins can perform somersaults and
leaps out of the water. After watching other
dolphins perform, they sometimes invent
their own tricks and stunts. Dolphins are
extremely friendly and have never harmed
anyone. They are very amusing animals.

What is an Astronaut?
The term "astronaut" is derived from the
Greek words "astron," which means "star,"
and "nautes," which means "sailor."
Astronauts are people who pilot, navigate,
and fly spacecraft. Cosmonauts are Russian
"star-sailors," with "kosmos" being the
Greek word for "universe." In 1961, Yuri
Gagarin, a Russian, made the first space
flight. It lasted a little more than 89
minutes.

Windsocks
To make a wind sock from a plastic bottle,
first cut the top and bottom of a two-liter
bottle to create a perfect cylinder. Then,
using a hole punch, make four evenly
spaced holes on top. Tie a 12-inch piece of
fishing line to each hole after that. Then,
connect all four to a large fishing swivel
snap. Sand the bottle and then paint it with
whatever design you want. When it's dry,
poke holes every inch around the perimeter.
Then, in each hole, tie a 3-foot piece of
ribbon. Colors can be varied or all the same.
Finally, hang up the phone and relax. The
words in the box may assist you in
comprehending the text.

How to Make Your Own Compost
Cornpost is the most nutrient-dense
fertilizer available. And with a little effort,
you can make it yourself. Compost is
made up of decomposing organic matter.
Compost can be made from leaves, grass,
2/ 62
decomposable kitchen scraps, and even
hair clippings. These materials are layered
with soil, manure, or a high-nitrogen
fertilizer in a container (or pile). Begin by
layering dry "brown" materials such as
wood, dried leaves, sawdust, or straw. Add
a layer of moist "green" materials from
your garden, such as grass cuttings, fruit
and vegetable scraps, coffee grounds,
eggshells, or prunings. Continue to add
layers, alternating "green" and "brown"
materials with soil and manure. According
to the recipe, the mixture should be kept
warm, wet (with a hose once a week to keep
the entire mixture moist), and aerated.
Every week or so, it will need to be turned
or mixed. If your compost isn't
decomposing, add chicken manure or bone
meal (for nitrogen). The compost will be
ready to use in your garden in 2-3 months!
When your compost is dark, combustible,
and resembles soil, it is ready. Mix compost
into the soil around existing plants once or
twice a year. Work into the soil liberally to
prepare new planting areas. spread around
the base of shrubs. Although compost can
be made in an open pile, using a bin will
yield faster results. A small kitchen
compost carrier can be hung on a cabinet
door or set on the counter. Larger yard bins
are now available for purchase everywhere.
There should be no use of animal
byproducts (meat scraps, grease, bones),
milk or dairy products, dog or cat
droppings, cardboard, or diseased plants.

Plastic
Plastic has now become an important part
of modern life. Most of the things around
us contain or are made of plastic. Our
blankets are made of nylon, a type of
plastic. The carpet is made of plastic. We
write with plastic ballpoints or pens. The
pans and pots we cook in, the toys our
children play with, and even the ears we
drive with all contain significant amounts
of plastic. Do you use a computer for work
or recreation? Some parts of your
computer are made of plastic. Plastics
have some advantages. They are relatively
inexpensive to produce. Some plastics are
as hard as stone and as strong as steel.
Some plastics are as clear as glass. They
are relatively inexpensive to manufacture.
Some plastics are as tough as steel and as
hard as stone. Some plastics have the
transparency of glass, the lightness of
wood, and the elasticity of rubber. Plastics
can be made in virtually any color and are
lightweight, waterproof, and chemically
resistant.
