Acid Rain
Number of Words: 375 / Number of Pages: 2
... Rain reacts to different types of soil and rocks in two ways.
1) Acid rain will dissolve alkaline rocks and soil, or will neutralize the
alkalinity.
2) Acid rain will increase the acidicy of already acidic rocks and soil,
such as granite, or the soil which results from corroded granite.
Acidic chemicals, and alkaline chemicals react to each other by
reducing the alkalinity or acidicy of each other. Which ever has the
strongest pH level, usually will neutralize or reduce the pH of the other,
but after the reaction is complete, both substances have undoubtably
changed, their pH moved clos ...

Atention Defficit Disorder
Number of Words: 1395 / Number of Pages: 6
... ADD are impulsive meaning to act without thinking. In one case a five-year old with ADD almost drowned when he went to a pool with his father. He saw people jumping into the pool and thought it would be fun. He jumped right in without remembering that he can't swim. He was pulled from the bottom of the pool several minutes later.
Hyperactivity is a real problem for people with ADD especially in children. Parents will usually describe them as always on the go. ADD girls tend to be less hyperactive than ADD boys are. The hyperactivity usually fades by adolescence. This doesn't mean all the ...

Great White Sharks
Number of Words: 433 / Number of Pages: 2
... offshore islands. They are also found in great numbers in the Australian waters.
The great white is a very agile killer that hunts mostly anything in the ocean. They
are carnivorous and usually prey on sick or injured prey. Just one drop of blood can make
the shark go into a feeding frenzy. It is not made to swim fast and its usual speed is
fifteen miles per hour. It migrates south to warmer waters to give birth to six to nine
pups. The only way it can defend itself is by using its mouth and its razor-sharp teeth.
One of the most largest specimens caught was off of Manta ...

Tiger Subspecies
Number of Words: 562 / Number of Pages: 3
... requests as to
the exact number of tigers, or a tiger subspecies left in the world. That tells
you that there are people that care. But there are so little tigers left that
we can not even keep track of them. We should look at the trend that the
population is taking, rather than the number as a slice in time. Just as you
might say of a young member of the Hunt family, that they were very wealthy. A
hypothetical individual was 24 years old and had $1,000,000. What isn'tavailable
in this one time analysis was that this Hunt inherited $24,000,000 at age 21,
has no education nor ever worked. At ...

Exploring The Mind
Number of Words: 967 / Number of Pages: 4
... similar way that can only be explained by an instinctive nature. Have young children changed their behavior since the 1700's? I suppose any child from any culture at any time in history would cry when it was upset, physically take whatever it wanted, need a certain amount of love and attention, and also be interested in exploring things outside of it's bounds. I feel that all of these instinctive behaviors seen in young children are emotions that I, as a young adult, have somehow came to deal wit as a part of society. Certainly other children, adolescents, and adults young and old alike understand ...

A Critique Of The Stanford Experiment
Number of Words: 592 / Number of Pages: 3
... (in this case a simulated cellblock
in the basement was used). All of the participants in this experiment at
first were thought to be similar in behavior but after one week, all of
that changed. The prisoners became "passive, dependent, and helpless."
The guards on the other hand were the exact opposite. They became
"aggressive and abusive within the prison, insulting and bullying the
prisoners."
After the experiment was finished, many of the mock guards said
that they enjoyed the power. Others said that they had no idea that they
were capable of being so corrupt. The experimenter was shocked ...

Caffeine

... Harvard Medical School in 1990 say that has no direct link to infertility either. Nor does it have an effect on a pregnant woman and/or her unborn child. In addition all of the talk that says will
stunt a child's growth is just rumors. is said not to affect children any differently then it does adults.
In another article entitled Coffee may not be so bad… in Science News, November 25, 1995, the author thinks that is an energy booster for athletes. At Oregon Health Sciences University a research team studied six healthy young men. The men rode exercise bicycles while the scientists recorded ...

Solar Cells
Number of Words: 1163 / Number of Pages: 5
... In electrical conductors,
these bands are continuous but in insulators and semiconductors there is an
"energy gap", in which no electron orbits can exist, between the inner valence
band and outer conduction band [Book 1]. Valence electrons help to bind together
the atoms in a solid by orbiting 2 adjacent nucleii, while conduction electrons,
being less closely bound to the nucleii, are free to move in response to an
applied voltage or electric field. The fewer conduction electrons there are, the
higher the electrical resistivity of the material.
In semiconductors, the materials from which sol ...

Nuclear Power In Ontario
Number of Words: 1130 / Number of Pages: 5
... AECL’s nuclear power program and marketing CANDU reactors. Nuclear power was cheap, if you did not have to worry about the waste. This was the answer to Ontario’s power problems, so they invested in the newest source of power at the time.
Most people believed that nuclear power was a good change in Ontario’s power structure, and there would be no real problems in the future. Ontario needed a new source of power in the 1950s; they found it in nuclear power and it solved the problem. In the 1950s the average person did not have a lot of knowledge about nuclear energy, and nuclear ...

Reproduction: A Courting To Nature
Number of Words: 967 / Number of Pages: 4
... in using words like love, grief and even
embarrassment to describe the behavior of these large, social birds.
At the same time he did not forget that all romance - animal and human - is
tied intimately to natural selection. Natural selection brought on the
evolution of males and females during prehistoric epochs when environmental
change was making life difficult for single-sex species such as bacteria
and algae. Generally, these reproduced by splitting into identical copies
of themselves. New generations were thus no better than old ones at
surviving in an altered world. With the emergence of ...
