“Let us give the children a vision of the universe‚” Wrote Maria Montessori in To Educate the Human Potential. “The universe is an imposing reality and the answer to all questions.” Montessori observed firsthand children’s eagerness to understand themselves‚ their world‚ and their place in it. It was her hope that Cosmic Education would allow children to grow into responsible sons and daughters of the great human family with the understanding‚ ethics and self-knowledge needed to transform the

THE EARTH IS PRECIOUS The earth gives us life and many things which we need in our daily life‚it provide us with natural resources which is mostly needed for humans and technology.But perhaps our planet is in great danger. For the last one hundred or so years‚ the people of earth have wasted and misused the natural recourses of earth. Several plans have been developed to stop the abuse of earth in which many of them can be executed by any one. Environmental problems have become so complex that many

THE EARTH At the beginning our planet is no more than a case of fire and cloud with glutenated dust particles similar to so many similar cloisters in the universe. This was the miracle where our life exists in this universe. Today life our life is just a link or chain of so many numerable living beings that was succeeded one another honours over nearly 4 billion years and even today new volcanoes continue to sculpt our landscapes it appears like molten rocks from the depths‚ solidifying‚ cracking

changes in Earth’s orbit and tilt‚ volcanic activity‚ human activity. 2. How orbital changes may affect climate? Ans. When Earth’s orbit is elliptical‚ Earth encounters more variation in energy from the Sun. The tilt of the Earth’s axis also changes. When the tilt decreases‚ temperature differences between seasons decreases. Wobbling of Earth changes the direction of tilt and can reverse the seasons. 3. How changes in CO₂ concentrations affect global temperatures. Ans. Carbon dioxide is a greenhouse

Origin of Life 1. The four stages of hypothesis for the origin of life on Earth by chemical evolution is * Abiotic synthesis of small organic molecules * The joining of small molecules into macromolecules * Packaging of these molecules into protobionts * The origin of self replicating molecules that made inheritance possible. 2. A.I. Oparin‚ and J.B.S. Haldane hypothesized a reducing environment. Stanley Miller and Harold Urey did lab experiments that showed that the abiotic

• Forests Forests is not just made of trees but also animals and micro-organism. Throw into the mix the non-living‚ abiotic components like soil‚ climate and water‚ and take in the complex interrelationships among the organisms and the environment‚ and we are closer to an actual understanding of this ecosystem. With one third of the Earth’s surface is covered with forests it is no surprise that they are among the most notable storehouses of biological diversity on the planet. Forests have a

Is it possible to unify religions‚ cultures‚ and races to ultimately achieve‚ what many beauty pageant contestants‚ call‚ “World Peace”? Good evening adjudicators and fellow students. Peace is defined as “a state of mutual harmony between people or groups”. This statement tells us that Peace on Earth is something

when the atmosphere and environment were different to those presently found on earth Archaea are single cell micro-organisms with no nucleus‚ it use anaerobic respiration (able to living in the absence of Oxygen) and live in extreme environment/condition such as high temperature‚ acid-rich‚ saline area etc. those environment are rich in minerals but hazardous to other organisms. Archaea’s population decreased after earth filled with oxygen‚ other than that‚ current archaea is very same as ancient

1. What transitions has Earth gone through and why? The young earth was anything but habitable. Radioactive elements decaying within its mass and impacts from debris raining down form space generated intense heat. There was no life during this era. Is called the Hadean era and was formed about 4.5 billion years ago. Hadean comes from the Greek word Hades which means “Hell”. That’s how hot the Earth’s temperature was. The next phase in the Earth’s history was the Archean era. It existed

Earth with No Moon A world with no moon would be much different without the Moon. Without the moon‚ Earth would be greatly different. The length of the day would be different‚ the origins of life on Earth would be slowed‚ and the biological evolution of life on Earth would vary greatly. But there would still be life on Earth‚ and many things on Earth would remain the same. Lunar tides are perhaps the most obvious effect of the Moon on Earth. The Earth without the moon would have a day that
