The Effects Of UFO's On People
.... of all UFO sightings could be easily explained. Most of
the sightings turned out to be celestial objects, such as stars or bright
planets like Venus, or atmospheric events such as auroras or meteors falling
through the atmosphere. Many other sightings turned out to be objects such as
weather balloons, satellites, aircraft lights, or formations of birds. Often
these sightings were accompanied by unusual weather conditions. Only 5.6
percent of these cases were not explained. Testimonies by people are often very
inaccurate and dramatized. People have the tendency to explain everything they
see, which is not usually complete .....

Design Of A Psychological Experiment
.... Will you treat all the participants in the same way? No, I would not treat
all the participants in the same way. The control group would not be given
caffeine. However, I would treat all experimental groups the same because that
will give more accurate results. If the participants were not treated the same
I would not be able to accurately measure how much or how little the caffeine
affected the students.
4) How will you select the participants of your study so that they are
representative of the students enrolled at UMCP? I would randomly chose
participants of different ethnic groups, ages, weights, and sexes.
5) What .....

The Beginning Of Time
.... Hubble found
the movement of the galaxies by using a phenomenon known as the Doppler effect.
This effect caused bodies moving away from an observer to have a "red-shifted"
spectrum (the light spectrum of the body had been shifted closer to red) and
bodies moving towards an observer to be "blue-shifted" (Hawking, 1988)
The expansion was traced backwards through time to discover that all the
galaxies had originated from the same point. It was later believed that all
matter spawn from that "center of the universe" discovered by Hubble, by means
of some sort of enigmatic portal. Matter would collect outside this singularity
and .....

Detection Of Biological Molecules
.... proteins. The
last part of this lab takes an unknown substance and by the four tests,
determine what the substance is.
BENEDICT'S TEST
Introduction: Monosaccharides and disaccharides can be detected because of
their free aldehyde groups, thus, testing positive for the Benedict's test.
Such sugars act as a reducing agent, and is called a reducing sugar. By mixing
the sugar solution with the Benedict's solution and adding heat, an oxidation-
reduction reaction will occur. The sugar will oxidize, gaining an oxygen, and
the Benedict's reagent will reduce, loosing an oxygen. If the resulting solution
is red orange, it tests posit .....

Chance Or Planning
.... it happens based on chance or natural selection. Whatever you believe or
disbelieve, life cannot be planned. No matter how hard a person attempts to
"plan" their path in life, it is by chance and luck where that path takes us.
Darwin's career was also based on chance, not planning. Darwin never planned to
become a scientist or the father of natural selection. It was by pure chance
that he obtained the job on the voyage of the Beagle, which started his career.
Darwin stated about this voyage that, "The voyage of the Beagle has been the by
far the most important event in my life and has determined my whole career. . ."

Differences And Effects Of Natural And Synthetic Fertilizers
.... called an alkaline soil, and will commonly kill
plants. Mineral content, as mentioned above, is also a concern, and must be
clearly monitored. After inspection, it is common for minor organic materials
outside fertilizers to be applied, such as peat moss, ground bark, or leaf mold.
It is after these steps that fertilization must occur, leading to a debate which
has plagued gardeners and scientists alike: organic or chemical?
Fertilizers, in both natural and synthetic breeds, are carriers of the
primary and secondary nutrients that are found less often in even the most
fertile soils. Fertilizers are mixtures that are mixed or ap .....

Galileo And Newton
.... "reasoning back and forth between theory and experiment." I feel that
Galileo's argument is a valid one because it explains relations in nature and
the physical world through mathematical analysis. This allows him to define a
world outside of human existence that can be logically calculated and explained.
His view describes the world in which living creatures live and not contrasts it
to the world within living creatures. The problem with Galileo's view is that
it pioneers a scientific outlook but never actually fulfills it.
Newton believes the world is ultimately made up of hard particles that
can retain different proper .....

resistance grass that needs no moving.
Scientists will soon be able to collect DNA from endangered species.
This DNA could be used to clone more condors, bald eagle, mountain gorillas, and
many other animals. Totally extinct animals may be recreated as well, i.e.
Jurassic Park. Imagine having your own dodo bird or pet triceratops.
Many types of diseases will be cured. Just take out the gene that giving
you the problem. Pure panacea. As soon as a baby is born his or hers parents
will know everything about him or her. If they will be artistic. Will she get
breast cancer? Will he be tall or .....

Diverrsity Of Plants
.... stomata, and seeds has made them progressively less
dependent on water. The oldest plant fossils date from the Silurian Period,
some 430 million years ago.
The common ancestor of plants was a green alga. The similarity of the
members of these two groups can be demonstrated by their photosynthetic pigments
(chlorophyll a and b,) carotenoids); chief storage product (starch); cellulose-
rich cell walls (in some green algae only); and cell division by means of a cell
plate (in certain green algae only).
Major Groups
As mentioned earlier, The two major groups of plants are The bryophytes-
-mosses, liverworts, and hornworts--an .....

DNA: The Making
.... bacteriologist Oswald
Theodore Avery proved that deoxyribonucleic acid (DNA) performed this role. He
extracted DNA from one strain of bacteria and introduced it into another strain.
The second strain not only acquired characteristics of the first but passed them
on to subsequent generations. By this time DNA was known to be made up of
substances called nucleotides. Each nucleotide consists of a phosphate, a sugar
known as deoxyribose, and any one of four nitrogen-containing bases. The four
nitrogen bases are adenine (A), thymine (T), guanine (G), and cytosine
(C)."(Caldwell 1996) "In 1953, putting together the accumulated chemic .....

Apollo 4
.... it turns to flammable
fumes. The capsule was filled with pure oxygen in an effort to allow the
astronauts to work more efficiently. It also turns normally not so flammable
items to highly flammable items. Raschel netting that was highly flammable in
the pure oxygen environment was near the exposed section of the wires.
At 6:31:04 p.m. the Raschel netting burst into an open flame. A second
after the netting burst into flames, the first message came over the crew's
radio channel: "Fire," Grissom said. Two Seconds later, Chaffee said clearly,
"We've got a fire in the cockpit." His tone was businesslike (Murray 191).

The Big Bang
.... cosmological principle. This principle
says that the universe is the same everywhere on the large scale, at all times.
It maintains the same average density of matter forever.
There are observational evidences found that can prove the Big Bang model is
more reasonable than the Steady State model. First, the redshifts of distant
galaxies. Redshift is a Doppler effect which states that if a galaxy is moving
away, the spectral line of that galaxy observed will have a shift to the red end.
The faster the galaxy moves, the more shift it has. If the galaxy is moving
closer, the spectral line will show a blue shift. If the gala .....
