Mosquito – Itchy Situation

Mosquito - Itchy Situation

Mosquito – Itchy Situation


Only the female mosquito bites and leaves those itchy lumps on our arms and legs. She needs the blood for her eggs to develop. The humming sound we hear comes from the fast beat of the mosquito’s wings. The male mosquito feeds on nectar and other plant juices. Mosquitoes are part of a large group of insects called flies. A mosquito has two narrow wings, two antennas, and six long legs. A female mosquito usually has a mouthpart called a proboscis, which looks like a long tube. There are more than 3000 species of mosquitoes.
Mosquitoes are usually found wherever the weather is damp or where there are rivers, lakes, or swamps. That’s because these insects must lay their eggs in water. They even lay eggs in tin cans partly filled with rainwater. Mosquitoes have four stages in their life cycle beginning with the egg, then proceeding into a larva stage, followed by a pupa stage, and finally adulthood. When the eggs hatch, the young mosquitoes look like little worms.

Astonishing Constellations

Astonishing Constellations

Astonishing Constellations


Since ancient times people have tried to explain the night sky. A constellation is a group of stars. The groups are identified according to patterns that people have seen in the stars and they are simply ways that people have imagined the stars. Over thousands of years different cultures have seen different patterns in the stars. They have named many different constellations after familiar animals, everyday objects, and characters and beasts from stories.
Today constellations provide a connection between modern humans and ancient stories. Astronomers have named 88 constellations and they use them to help describe the location of specific stars.
There are 12 well-known constellations that lie in a band of space called the zodiac: Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpius, Sagittarius, Capricornus, Aquarius, and Pisces. Today astronomers have calculated that during the period from November 27 to December 17, there is one more zodiacal constellation on the horizon – Ophiuchus.

Bullfinch – red spot on snow


The bullfinch has a bright red breast and gray back set off by a coal–black head. However, only males have red breasts, the female’s breasts are brown. They have an excellent ability to imitate different sounds. Some of these birds can memorize and whistle several very complex melodies. All you need is patience to train a bird. It is quite easy to tame bullfinch.
Despite the fact that most bullfinches live in Eurasia, the largest of them, white-cheeked bullfinches, live in the hot Philippines.
In captivity, these birds live less than in nature. The weight of an adult bullfinch is about thirty grams.
Bullfinches are monogamous. During the breeding season, males coax females by offering food. Males never take part in the construction of a nest. Nestlings of bullfinches gain their independence in the third week of life.

Paper – useful material


People use paper for writing, printing, wrapping, and many other purposes. Hundreds of years ago people made paper by hand. Today machines produce most paper. First, the wood fibers are soaked in water and creates a soupy mixture. Next, this mixture is spread on a screen and rollers press out water. Once the fibers are dry, they have become a sheet of paper.
Paper is available in a wide variety of weights, colors, textures, and finishes for a multitude of purposes. Everyday writing and printer paper is thin and smooth. Paper used for arts and crafts is thicker and textured. Cardboard is a thick type of paper used to make packaging. Paper used for newspapers is thin and cheap. Recycled paper is made from used paper.

Power of Fire

Power of Fire

Power of Fire


Civilization would not be possible without fire. Human beings have known how to control fire for almost 1.5 million years. But for many thousands of years after that, people still found it difficult to start a fire. One method they used was to strike one hard mineral against another to make sparks. A second method was to twirl one piece of wood against another until the wood heated up to its ignition point.
Fire is very useful. Campfires kept people warm and scared off wild animals. Fire lit the way at night and also cooked food. Later people set fires to clear land for farming. They used fire to make pottery from clay, to shape metals. Fire is used in many factories to operate furnaces or heat boilers. In a steel mill it is used to melt the materials that go into making steel.
However, fire is dangerous. It always must be used very carefully.

Automobiles History


The first true automobile was a machine that had three wheels and was powered by steam. It was built by Nicolas-Joseph Cugnot in 1769. It was heavy and moved very slowly. A disadvantage of steam was that water had to be brought to a boil before the car could go. During the late 1890s and early 1900s manufacturers produced cars run by electric motors. Electric cars did not run well at high speeds and had to have their batteries recharged every 80 kilometers.
In 1860 Etienne Lenoir developed a gasoline-powered internal-combustion engine and 16 years later the German Nikolaus Otto built an improved gasoline engine. In 1893 the brothers Charles E. and J. Frank Duryea built the first successful gasoline-powered car in the United States.
