Before beginning our research on radio waves‚ to us‚ radio waves were just waves going through the atmosphere‚ carrying sound from one place to another. Those were our ignorant days! We did not realize the complicated terms and theories involved. In the following report you will see how we advanced in our knowledge of radio waves‚ and we hope it will do the same for you. Radio waves are a combination of two kinds of electric vibrations. Audio frequency waves‚ which represent voice and other

Ozone in the stratosphere is a good thing‚ when in this layer it absorbs much of the suns ultraviolet rays and protects us from harm. In the troposphere however‚ it is a different story. Ozone there is a combination of hydrocarbons‚ nitrogen oxide‚ oxygen‚ and automobile gasses that comes together as a secondary air pollutant. This pollutant not only injures plant tissue‚ but can go as far as

Weather= atmospheric conditions at a particular time & place. (Temp‚ pressure‚ humidity‚ cloud cover‚ etc) Climate= the average weather over a long period of time.

In the upper atmosphere (stratosphere)‚ the protective ozone layer is beneficial to people because it shields us from the harmful effects of ultra-violet radiation. However‚ ozone in the lower atmosphere (troposphere) is a powerful oxidizing agent that can damage human lung tissue and the tissue found in the leaves of plants Ozone is also a greenhouse gas [->3]in the upper atmosphere and‚ therefore‚ plays a role in Earth’s climate.

“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
