The big burning ball of gas that holds nine major planets in orbit is not unlike many stars in the universe. The Sun makes up 99.86 percent of the solar system’s mass and provides the energy that both sustains and endangers us. Scientists have lately begun calling its tremendous outpouring of energy “space weather.”

The fifth planet from the sun is a huge ball of gas so massive it could hold all the other  planets put together. What we can see of the planet are bands of the highest clouds in a thick  atmosphere of hydrogen and helium. Traces of other gases produce the bright bands of color.
The Red [...]

Much like its neighbor Jupiter, the sixth planet from the sun has a  rocky core and a gaseous surface. But Saturn is chiefly known for its  intricate series of rings that encircle it. The mile-thick rings are made of  countless orbiting ice particles, from less than an inch to several feet in  size.
Up close, it’s [...]

Pluto, which is only about two-thirds the size of our moon, is a cold, dark and frozen place. Relatively little is known about this tiny planet with the strange orbit. Its composition is presumed to be rock and ice, with a thin atmosphere of nitrogen, carbon monoxide and methane. The Hubble Space Telescope has produced [...]

Made of dust, ice, carbon dioxide, ammonia and methane, comets resemble dirty snowballs. You may remember them as blurry smudges in the sky. Comets orbit the Sun, but most are believed to inhabit in an area known as the Oort Cloud, far beyond the orbit of Pluto. Occasionally a comet streaks through the inner solar [...]

Uranus
The seventh planet from the sun is much like its gaseous neighbors,  with a cloudy surface, rapid winds, and a small rocky core.
Uranus: personification of heaven in ancient myth
Perhaps because of a collision with a large object long ago, Uranus  orbits at an extreme tilt of 98 degrees — sort of on its side. This [...]

Asteroids
Quick quiz: How many planets orbit our Sun? If you said nine, you’re shy by several thousand. Scientists consider asteroids to be minor planets - some are hundreds of miles wide (and seldom round).
Orbits
Most, but not all, orbit the sun in an asteroid belt between Mars and Jupiter. The huge gravitational pull of Jupiter accelerated [...]

The Ant and the Chrysalis
An Ant nimbly running about in the sunshine in search of food came across a Chrysalis that was very near its time of change. The Chrysalis moved its tail, and thus attracted the attention of the Ant, who then saw for the first time that it was alive. “Poor, pitiable animal!” [...]

The survey was carried out on the 4th of December in Secondary School of Humanities; among 11 students of from 9C aged 14-16.
A task, which our group asked the students to do, was about to choose the main problems at their school from out list. These problems were:
Wearing uniform
Go to school everyday
Do not chew gum
Do [...]
