as alternative energy sources are starting to become an important factor in the human society. Solar power energy is one alternative energy source often over looked that our society should begin using. Solar power energy works like this‚ “When sunlight hits a solar panel‚ it makes electrons in the silicon move around. (Electrons are teeny tiny specks—they’re way too small for us to see‚ even under a microscope.) The electrons flow through wires that were built into the solar panel. And presto!

is important for life because the fresh air from the chlorophyll is doing photosynthesis. Plants also make food and oxygen. Then plants is doing photosynthesis‚ it must have sunlight to make their own food and oxygen. The equation about photosynthesis basically is CO2 + H2O C6H12O6 + O2 ( means need the chlorophyll and sunlight). Photosynthesis can make their own food and also oxygen for Earth as well‚ so photosynthesis is absolutely important for life. Inside the plant‚ it has a power house called

and refraction of light in water droplets in the Earth’s atmosphere‚ resulting in a spectrum of colors in the sky. It takes the form of a multicolored arc. Rainbows caused by sunlight always appear in the section of sky directly opposite the sun. Rainbows can be observed whenever there are water drops in the air and sunlight shining from behind at a low altitude angle. Rainbows can be caused by many forms of airborne water. These include not only rain‚ but also mist‚ spray‚ and airborne dew. First

Since you have the red hair gene‚ you produce your own vitamin D. While sunlight may be the ginger’s kryptonite‚ in the right amount it is extremely beneficial. Our pale skin allows us to absorb more sunlight than other people and our bodies create more vitamin D than our darker haired companions. Our ability to absorb sunlight where it is seemingly nonexistent is our strength‚ but it is ironically our downfall in sunny climates. It turns out the

The writer describes the girl’s hair as a wave of sunlight. Sunlight and light shining down is traditionally linked with freedom and hope. The writer uses this metaphor in order to get the sense of freedom across to the reader. The sunlight running down the granddaughter’s

3/22/2013 Lab 1- The scientific method In this lab I am learning about the steps of the scientific method and how it can be applied to daily life. In my first exercise I analyzed data presented to me in a table (table 2) on fish population in relation to the amount of dissolved oxygen ( ppm ) in the water. The patterns indicate that when more dissolved oxygen (ppm) is present in the water‚ the number of fish observed increases. In developing a hypothesis for this theory‚ I have decided that if

Throughout the whole film‚ Grace was always making sure the blinds were shut in order for them to walk through any place that had doors or any sort of windows. They could not be around any type of sunlight whatsoever. Something I learned in Psychology

Solar power is the conversion of sunlight into electricity. Sunlight can be converted directly into electricity using photovoltaics (PV)‚ or indirectly with concentrated solar power (CSP)‚ which normally focuses the sun’s energy to boil water which is then used to provide power. Other technologies also exist‚ such as Stirling engine dishes which use a Stirling cycle engine to power a generator. Photovoltaics were initially‚ and still are‚ used to power small and medium-sized applications‚ from the

“Solar Radiation and its Effects on Planet Earth” The Sun emits a tremendous amount of energy‚ in the form of electromagnetic radiation‚ into space. If we could somehow build a gigantic ball around the Sun that completely enclosed it‚ and lined that ball with perfectly efficient photovoltaic solar panels‚ we could capture all of that energy and convert it to electricity and be set in terms of Earth ’s energy needs for a very long time. Lacking such a fanciful sphere‚ most of the Sun ’s energy
