Star Mars

... early arguments we now know to be almost certainly erroneous, but even the most recent pieces of evidence do not unambiguously demonstrate the existence of life on Mars." ( Sagan and Shklovskii 273) Some scientist believe man should look up in the sky searching for new habitats for future generations, since human kind today seems to be going backwards in many aspects of the earth's ecology. The first attempt would be to study the moon; the second, our neighbor planet. Unfortunately, our actual technology slightly provides strong, useful ...

Acid Rain

... ten times as acidic as a lake with a pH of 5, and a lake with a pH of 3 is 100 times as acidic, After many rain falls of , the pH of a normal lake ( 5.8 ) to 4. has been known to reach the acidicy of pH 2, ( battery acid has a pH if 1 ) this is a drastic change, as normal rain is average pH 5.2. can dissolve limestone and chalk, and corrodes outdoor structures. Statues and monuments that are left unprotected can fall victim to the unpredjudiced destruction of . Acid Rain reacts to different types of soil and rocks in two ways. 1) Acid ...

Bottle Rockets

... reaction. For the rocket to launch it needed to be propelled by something, for our rockets we used regular air and compressed it. Upon releasing the stopper Newton’s first law went into effect which states that for something to move a force must act upon it in this case the gas moving out of the bottle. When the stopper was pulled the pressure in the bottle forced its way down, which applied the force to start the motion of the bottle. His 3rd law can also explain this because the water going down forces the rocket in the exact opposi ...

The Rain Forest - Example Of A Flourishing Ecosystem

... but hopefully I will have given you a better understanding in the end. A rainforest is a complicated structure which is put together from an unlimited amount elements that all work together. A hole anywhere in this system can cause a breakdown that effects the entire structure. The bottom of the rainforest is the soil upon which everything must grow. Wherever rainforests are found, sandy red coloured soil can be found as well. This soil contains few nutrients, which is why attempting to grow any sort of crops would be futile. O ...

Hurricane Andrew

... about one category on the during the transit over land, and the pressure rose to about 950 mb, Andrew was still a major hurricane when its eyewall passed over the extreme southwestern Florida coast. The first of two cycles of modest intensification commenced when the eye reached the Gulf of Mexico. Also, the hurricane continued to move at a relatively fast pace while its track gradually turned toward the west-northwest. When Andrew reached the north-central Gulf of Mexico, the high pressure system to its northeast weakened and a stron ...

The Effects Of Processing Vegetables

... elements into energy ourselves we have to ingest complex food materials directly . One component of a well balanced diet must include Vitamins. Vitamins are chemical compounds that have no energy value, but instead act as catalysts inside the body. One variety of vitamins is the Vitamin A. This group includes retinol and carotene. Carotene is a yellow pigment found in vegetables such as carrots. A diet that is lacking in Vitamin A depreciates a person’s ability to see in the dark. Which is where the saying that carrots will make you see be ...

Plants

... shelter, fiber, and drugs. At the head of the list are rice, wheat, corn, legumes, cotton, conifers, and tobacco, on which whole economies and nations depend. Of even greater importance to humans are the indirect benefits reaped from the entire plant kingdom and its' more than 3 billion years of carrying out photosynthesis. Today the world's biomass is composed overwhelmingly of plants, which not only underpin all food webs but also modify climates and create and hold down soil, making what would otherwise be stony, sandy masses habitable ...

The Depletion Of The Ozone Layer

... are changing our ozone, and that the shield needs to be protected from all of the factors that are making it disappear. There are many factors that affect how quickly the ozone depletes. The main problem with the decaying ozone layer consists of people being careless. Many times, the chemicals released into the air by people drift into the ozone and form harmful chemical bonds with ozone molecules. One example would be chlorofluorocarbons or CFC's. CFC's were commonly found in spray cans during the early 1970's but were invented in ...

Newton's Law Of Universal Gravitation

... of the two curiosities (the other being the moon) that led Newton to discover The Law of Universal Gravitation in 1666 (Eddington 93). As Newton later wrote, it is the story of the sight of an apple falling to the ground (he was resting at Woolsthorpe because of the plague at Cambridge) that caused Newton to wonder if this same force was what held the moon in place (Gamow 41). Newton knew that an object fell to the earth at a rate of about 9.8 meters (32 feet) per second second as pointed out by Galileo. Thus "the apple that fell from the ...

Stars

... of 10 parsecs or some 32.6 light years. Obviously, Deneb is intrinsically very bright to make this list from its greater distance. Rigel, of nearly the same absolute magnitude, but closer, stands even higher in the list. Note that most of these distances are really nearby, on a cosmic scale, and that they are generally uncertain by at least 20%. All stars are variable to some extent; those which are visibly variable are marked with a "v". What are apparent and absolute magnitudes? Apparent is how bright the appear to us in the sky. Th ...

Cloning 3

... This means that gene donors would obviously have the exact same DNA as their clones. If large groups of people have the same genetic information, a disease could instantaneously wipe out the entire population. Our genetic make-up is what makes us unique. It gives us a sense of individuality and distinctiveness. If many people had the same DNA, how would we preserve our diversity and sense of self? Human cloning also raises many ethical and moral issues. Different religious groups regard cloning in different ways, but most agree on one point. ...

Asimov On Chemistry By Isaac Asimov

... weight. Slow burn This is a description of how Isaac newton contributed to the field of chemistry along with what civilizations thought of chemistry. Then he talks about a pathologically shy, absentminded, stuffy, women-hating chemist. This man did make some discoveries about inflammable gas and proved water to be an oxide. The Element of Perfection Asimov talks about astronomers in the mid 1800's, and how they made the spectroscope. Only then does he start to mention a element a french chemist belived to be new or maybe just a heavier f ...
