Director's Choice Ideas
From time to time I come up with,
or come across, a project idea / concept that I will notate
below. These ideas will only be in hypothesis type format, and will
not have any hard conclusions available. They are of the substance
of ideas that there has been no known or very little research
done. Please feel free to
take these ideas and "run with them". But keep this in
mind - As Director of the Louisiana Region 5 Science and Engineering Fair,
I in no way get involved with the Judging, nor do I have any influence on
the decision of the Judges. I do not know who the winners of the
awards are until I am handed the list at the beginning of the awards
ceremony. In other words, don't research any of these ideas
just because I suggested them.

Earth
Sciences -
Scientists have not be able to accurately predict when, or where,
earthquakes will occur. Believe it or not, there appears to be
on the average of 10 recorded tremors throughout the world on any
given day. The depths of these disturbances can be anywhere from
a few miles to 600+ miles. In 2003 there were several major ( 7+
magnitude ) quakes that took place in various spots of globe.
Shortly afterward, there seemed to be a rash of minor to moderate
quakes in other areas of the world. Does a major quake set off
or trigger other quakes in other quake prone areas? If a major
quake takes place at the 300 mile level, and if there is an increase
in quake activity in the days following this event, then at what depth
do they normally occur? What, if any, is the correlation?
I would suggest starting out at the following site:
http://neic.usgs.gov/neis/bulletin/bulletin.html
. This link to the USGS has a great database of historical data
that could be used. You might want to consider drawing up or
designing some type of global 3D model to depict the results of your
research. While you are collecting the information, a few other
good questions are, "Is there a time of year that the frequency
of increase? Is there any comparison to this frequency in
regard to the Northern and Southern hemisphere?" Anyway, go
for this if you are into doing some fascinating research. Added
Note: I recently (Early December) stumbled across an interesting
site - http://www.syzygyjob.com/
. The scientist here has done a
lot of research in earthquake predictions in correlation to tidal
activity. He forecast the December quake in California, Oregon,
and the 7.0 in the Pacific Ring of Fire. Check out the site and
read up on the concept. When someone goes 3 for 3 in a 7 day
period, he has my vote of confidence. An added suggestion is to
make a graphic 3D model of yearly earthquakes. The model would
be based on depth and location (lat / long). You might be able
to show that a sizable quake at a certain depth will set off another
one at about the same depth. For example, on December 23, 2004,
there was a 8.1 North of Macquarie Island at a depth of 10 KM.
Three days later there was a 9.0 off West Coast of Northern Sumatra,
also at a depth of 10 KM. Maybe
design a software program that could be used to download information
about recorded quakes (location, strength, depth, etc) and
automatically plot each one in 3D. Good
luck!

Behavioral & Social
Sciences - In the December 2003 edition of Discover, I ran across the following article by Alison McCook,
entitled "Out With One Sense, In With Another" - The music
of Stevie Wonder and Ray Charles supports the common belief that
loosing one sense can enhance another. Italian researchers have
better evidence. They find that after only 90 minutes,
blindfolded people can develop a keener sense of touch - a sign that
the portion of the brain dedicated to vision can help process other
senses. Although such neurological flexibility used to be
considered a feature of a developing brain, we know now that, even in
adults, it is possible to find plastic interactions. Salvatore
Aglioti, a neurologist at the University of Rome La Sapienza asked 28
test subjects to place their fingers on a series of plates marked with
grooves of varying sizes, with the width of the grooves equal to the
distance between them. Some of the grooves were so fine that the
surface of the plate felt smooth. After being blindfolded,
however, people were able to feel grooves that were more subtle than
the smallest ones that they could discern in a previous test.
Repeating the test a couple of hours after the blindfolds were
removed, the subjects' sense of touch had reset to normal. - What I
would suggest if you would like to tackle this idea is use a larger
test group. See if there is any sensory difference between males
and females. See if age of the test subject results in any
distinct divergencies. I am sure there are a few other angles to
this idea that you can come up with, that I haven't. Give it a
try.
-
Medicine &
Health - Also from the December issue of Discover,
an article entitled - Forecast: A Chilly Scorcher - How Your Body
Mistakes A Cold Front For a Heat Wave. Experment 1: Find two
glasses and three identical knives with metal handles. Fill one
glass with cold water and ice cubes, and place one of the knives,
handle first, into it. Next, fill the other glass with tap water
that is very warm but not painfully hot. Then dunk the remaining
two knife handles into the heated water for 60 seconds. Ask a
friend to extract the knives, fit the cold handle snugly between the
two warm ones, and then quickly touch the three handles to the inside
of your wrist as you close your eyes. You'll experience a
burning sensation that is more intense than what would be evoked by
placing the two warm handles on the same spot. The sensory
confusion, which neurologists call the thermal-grill illusion, may
occur because cold objects touching the skin simultaneously stimulate
both fast-conducting (A-delta type) nerve fibers that signal cold and
slower (C-type) fibers that signal pain. Fast and slow sensory
nerves connect to a single place in the spinal cord, and that pain
information is then passed on to the brain. Signals from the
faster, cold-transmitting fibers inhibit those spinal relays from the
slower, pain-transmitting fibers. The net result is that cold
stimulus elicits cold but not pain sensations , even though some pain
fibers are initially turned on. However, two warm stimuli placed
right next to a cold object can dilute the amount of cold information
flowing from a patch of skin. In Experiment 2 - The
dilution of a cold stimulus by a warm one implies that the different
signals are blended over a broad patch of akin - a phenomenon known as
spatial summation. Repeat Experiment 1, but this time ask your
accomplice to place the handles on your lips. You should
perceive a three-part warm-cold-warm sensation (with no pain).
That is because your lips do not lump together tactile inputs from
broad swaths of skin and so can discern much finer details.
Neurologists study temperature-pain illusions because about 3 million
Americans who have nerve damage from diabetes or trauma experience a
disorder called neuropathic pain. For these individuals, even a
light touch or a cool breeze can produce extremely painful, burning
sensations. Research thermal-grill illusion and spatial
summation. Get some test groups - females, males - young and
old. Does the summation subside with age or physical
condition? See if other parts of the body are affected in the
same way or not. This definitely would be a unique project to
enter at Region 5.

Computer Sciences
- Is the world really getting smaller? - Six Degrees of
Separation. I had always heard this saying but never knew what
it really referred to, until I stumbled onto this site: http://smallworld.columbia.edu/.
Even though this particular site experiment is over it would make for
a unique project. It is basically an experiment to test the idea
that any two people in the world can be connected via "six
degrees of separation". The objective is to get a message
to a target person somewhere, by forwarding the message to a friend of
yours - someone who is closer to the target than you are. (If
you happen to know the target, you could of course send it directly to
them) The should work on a state or nation wide
basis. Before the age of the Internet, conducting a project of
this type would have been very difficult. I suppose that one
restriction would be that you could not actively search the Net for
the individual. You had to rely on someone you knew, and they
had to rely on someone they knew, etc. The results for the Small
World project can be found here: http://smallworld.columbia.edu/results.html.
It is an interesting concept. Give it some thought.
-
Medicine & Health
- One of the more interesting projects that I like deals with testing
subject's sense of taste. My daughter did a project some years
back that involved testing her subject's tongues with sweet, sour,
bitter, and salty solutions. She broke the result down based on
gender, age, and smoking - nonsmoking. (A lot of photos and a
lot of charts and graphs) She placed second in State
competition. It was after the project that I learned about a 5th
taste - Umami. Had she known about these mysterious receptors, my
daughter would have included it in her experiment. After reading
more about Umami, I am beginning to believe this has something to do
with my great love for Chinese food. I would suggest doing a
project that includes the four senses, plus the 5th sense - Umami.
Another part of this project could include some research on the
palate. Taste buds are not only located on the tongue.
They are also found on the human palate. I have noticed that in
recent years, the taste buds on my palate have become extremely susceptible
to the different tastes, even more so than the ones on my
tongue. Could it be that as a person gets older, most of the
tasting occurs on the palate vs. the tongue, or is there something
else going on? We emailed Dr. Linda Bartoshuk,
one of the world's foremost experts in the study of taste and the
senses. Following was her reply: It is hard to find information about the pallet. It might help for you to have the name of the nerve that carries taste information from the pallet to the brain. It is the greater superficial petrosal nerve. If you look up that nerve, you will find information about taste.
There is information about taste on the pallet in other species and in humans. We do measures of taste on the pallet routinely in the laboratory. You might be interested to know that the tongue map in so many text books is wrong. The maps suggest that the front of the tongue tastes sweet, the back, bitter and the sides, salty and sour. Actually, this is based on a mistranslation of a German article. I love to tell people this because I am at Yale and the professor who mistranslated the article was at Harvard! Wherever there are taste buds, we taste all four tastes: sweet, salty, sour bitter.
This goes for the pallet as well.
Working with, or incorporating Umami and the palate would bring
the taste testing project into a whole new and unique area. If
you end up wanting to tackle something like this and would like some
more pointers on how to make this a successful project, them email me
and let me know.

Earth &
Science - One of my hobbies, ever since I was doing science
projects in the 4th grade, is weather. (In particular SEVERE
weather) It is on my agenda to, some spring, take a Tornado
chasing tour in Oklahoma. But in the meantime, I monitor Nexrad
Radar, via WeatherTap,
in the SW Louisiana area. Over the years I have noticed when a
strong front, or area of severe thunderstorms, approaches the Lake
Charles area, a great majority of the time the storm cells will either
dissipate or deviate off track before striking the metropolitan
area. I have noted this most of the time when the weather is
coming from the southwest. Base reflectivity is a good
monitoring point for what I am talking about. What, in the
natural landscape, or man-made landscape, might, if at all, be causing
this to take place? Does Big Lake have anything to do with
this? To do this type of research would require a long period of
weather monitoring. (Over a year's period). There are other
weather services out there that are free of charge that have radar
loops from which this could be studied. (AccuWeather,
Lake
Charles Weather Bureau, Intellicast, etc.) You would want to
save these animated gif loops to your computer for study and
comparison. These would also be used for display data for your
project. Don't stop at just Lake Charles. Look at loops in
other major metros of the country and see if you can tell if it is
happening elsewhere. I am not saying that this always
happens. But it happens enough to throw up a red flag. If
you are a weather nut like I am, you might start watching this
closely. You might end up discovering something of
meteorological importance!
-
Medicine
& Health - This may seem like a "gross" idea for
a project, but I did not find there has been that much research done
on this. You may have heard the tale that "asparagus
urine" is linked to higher intelligence. The fact is that
it is the result of a simple chemical reaction. Asparagus
contains a sulfur compound called mercaptan. Mercaptan is a
sulfur-containing organic compound with the general formula RSh,
where R is any radical, especially ethyl mercaptan, C2H5SH.
It is also called thiol. When your digestive tract breaks down
this substance, by-products are released that cause the odd scent in
your urine. The process is so quick that your urine can develop
the distinctive smell within 15 to 30 minutes. But not
everyone has this experience. Your genetic makeup
may determine whether your urine has the odor - or whether you can
actually smell it. Only some people appear to have the gene for
the enzyme that breaks down mercaptan into its more pungent
parts. I read that a study published in the May 1989 British
Journal of Clinical Pharmacology found that 46% of 115 people tested
produced the odor in one group of British citizens, while 100% of 103
people produced it in a group of French citizens. Another
study found that 10% of a group of 300 Israeli Jews could not detect
the odor. This may all sound scary, but it is not
bad. On the contrary, asparagus is s powerhouse of
nutrients. Here is where the research and experimentation would
come into play. This bit of research that I located points only
to nationality. I would suggest doing testing on males vs.
females, different age groups, smokers vs. non-smokers, different
nationalities, average weight vs. overweight, etc. Try to
establish a pattern. Try to identify which types of people have
a genetic makeup that allows the mercaptan to break down at these
accelerated rates. One benefit is this could lead to research
that would lead to developing medicine that would get into a person's
system faster. This is a project that has a lot of
potential. Generate a question form for the test subject and
supply them with some asparagus. Have them return only
the questionnaire to you.

Behavioral
& Social Science - In the March 2004 issue of Scientific
American, I ran across an interesting concept -
Perceptual-Blindness. As related in the article - Picture
yourself watching a one minute video of two teams of three players
each. One team wears white shirts and the other black
shirts, and the members move around one another in a small room
tossing two basketballs. You task is to count the number of
passes made by the white team - not easy given the weaving movement of
the players. Unexpectedly, after 35 seconds, a gorilla enters
the room, walks directly through the farrago of bodies, thumps his
chest and, nine seconds later, exits. Would you see the
gorilla? Most of us believe we would. In fact, 50 percent
of subjects in the experiment by Daniel Simons of the University of
Illinois and Christopher Chabris of Harvard, did not see the gorilla,
even when asked if they noticed anything unusual. They have a
paper which can be accessed at http://viscog.beckman.uiuc.edu/djs_lab/
. These experiments reveal our perceptual vainglory, as
well as fundamental misunderstanding of how the brain works. We
think of our eyes as video cameras and our brains as blank tapes to be
filled with sensory inputs. Much of what passes before our eyes
may be invisible to a brain that is focused on something else.
Driving is an example. Many accident reports include claims
like, "I looked right there and never saw them."
Motorcyclists and bicyclists are often the victims in such
cases. One explanation is that car drivers expect other cars but
not bikes, so even if they look right at the bike, they sometimes do
not see it. I would recommend conducting testing of this nature, using
homemade videos. See if perceptual blindness is more prevalent
in males or females, and old or young. Try to find a trend that
will identify who or what test group is more likely to experience this
phenomenon. Perceptual blindness, I believe, is also sometimes
called Change Blindness and Inattentional Blindness Another site to
check out would be - http://www.visualexpert.com/Resources/inattentionalblindness.html
This project would have a high probability of coming away with
numerous awards if done correctly.

Environmental
Science - Phytoremediation. Phytoremediation is an
innovative technology that utilizes the natural properties of plants
in engineered systems to remediate hazardous waste sites. I ran
across an article recently where researchers are even trying to use
this concept to remove gold particles from the ground around gold
mines. There are numerous sites with information on
phytoremediation throughout the Internet. Just route your
browser to Google
and do a search. As this research is in its infancy, it would
make a great project. You might even discover something someone
else has not thought of.
-
Behavioral
& Social Science - Does birth order influence
personality? I ran across this concept a while back. It
seems some believe that in families with multiple children, the order
of their birth predisposes each child to a certain type
personality. If you route your browser to the following link you
will see the article. http://www.thelouisvillechannel.com/family/3784843/detail.html
Some research indicates that a First Child is: Self-confident and a
perfectionist due to the feeling that their parents watch their every
move. A Middle Child is: Social, a good negotiator, and may feel
left out in the middle position with focus going to the oldest and
youngest. The Youngest Child is: Charming and may feel
inferior to the older children. There is one more link on
this aspect that might help. http://il.essortment.com/birthordersibl_rbay.htm
You could even include in your research a related possibility that
birth order affects intelligence. If you go to the following
website you will get some more information with which to start. http://www.indiana.edu/~intell/birthOrder.shtml
Add this to your research - Does Birth Order and Demographics affect
your personality? http://jrscience.wcp.muohio.edu/nsfall99/FinalArticles/Birthorderanddemographics.htmlI
have not seen a project of this nature so I believe if done properly,
with a lot of research using many different families, it would be a
winner. Good Luck!

Medicine
& Health - The following is another article written by
Alison McCook. NEW YORK (Reuters Health) - Skipping a meal or two makes you more sensitive to the taste of your next sweet or salty snack, new research shows.
After a group of people went for about 15 hours without eating, they became better able to taste the miniscule amounts of sweet or salty flavors added to solutions, compared to when they tasted the same solutions on a full stomach.
In contrast, hunger had no influence on participants' abilities to detect bitter tastes, the report indicates.
"We have discovered that hunger increases sensitivity of taste to sweet and salty substances but it does not affect taste sensitivity to bitter substances," study author Dr. Yuriy Zverev told Reuters Health.
Zverev added that hungry people's taste buds may respond differently to salt, sweet and bitter because those tastes communicate different things about our food. Sweet and salty tastes are often signs that a particular food is edible, he explained, so when we are hungry, our bodies become more sensitive to what foods can fill our stomachs.
Once we are full, however, it is less important for us to be tuned into food, and we may consequently lose our sensitivity to the taste cues of what makes something edible. As he put it, "Biological significance of substances of nutritional value declines after a meal."
In contrast, a bitter tastes signals that the food is "not suitable for consumption and should be rejected," Zverev noted, and this is an important message to heed, regardless of whether or not we are hungry.
During the study, Zverev, who is based at the University of Malawi, asked 16 non-obese men to taste a number of substances that contained different concentrations of sweet, salty and bitter flavors. He measured the least amount of flavor needed for participants to correctly identify the taste when they were not hungry, and compared that to least flavored solution they could taste when hungry.
During periods of hunger, people could taste the sweet and salty flavors added to solutions that they rated as tasteless when well-fed, Zverev reports in the journal BMC Neuroscience.
Although the bodily processes that enable tasters to change their sensitivity to flavors when hungry are not clear, Zverev suggested that periods of hunger may result in changes in the taste buds themselves or the regions of the brain that process taste. SOURCE: BMC Neuroscience

Medicine
& Health - As I was running an errand the other day, I
passed under a run of high-voltage power lines. (The passed over
the roadway) This brought to mind past and current concerns by
folks that living under or near high-voltage lines, and EMF's, can
cause negative physiological effects on the human body. I know
there have been studies done on trying to tie in certain types of
cancer and increased health symptoms with high-voltage
equipment. The latest information that I can find indicates that
results of studies are not definitive. What did come to mind was
this. If you are able to legally and safely access
the area underneath high-voltage lines then try doing a research
project that determined if underground life directly under the lines
was less abundant than the same type of life 200 feet away. I
would suggest taking soil samples of various depths and distances in
parallel with the lines. See what type of animal or insect life
is present. Log down the type of size of what you found along
with the depth and locations. ( x inches, x feet from the tower,
earthworms averaging 5 inches in length and 1/8 inch diameter, and any
other forms of life that reside in the soil). Then proceed out
200 feet away and repeat the process covering the same distance and
depth. One thing you would want to try to make sure is that the
soil type and consistency was as much the same as possible.
Also, if you can get access to a EMF meter to take readings, that
would be a plus. You might try contacting an electrical
contractor or the science department of a local college or
university. I did a quick search on the Internet for any type of
studies similar to this idea and have discovered none. Who
knows, you might discover something that no one else has.
-
Earth
Science - Here is an idea that would take a good bit of
data collection and research. As many of you know, I have been a
meteorology enthusiast all of my life. When Hurricane Katrina
made landfall in SE Louisiana the reported barometric pressure was 915
mb with reported sustained winds of 145 - 150 mph (Category
4) Relating to the following Category 5 storms that made
landfall on the continental US, the Great Labor Day Storm of 1935 (bp
- 892 mb with estimated winds of 190 mph), Hurricane Camille 1969 (bp
- 909 mb with estimated winds of 200 mph), Hurricane Andrew 1992
(bp - 922 mb with estimated winds of 160 - 165 mph). If you drop
down to Hurricane Donna in 1960 - Category 4 - the bp was at 930 mb.
Is there a direct relation between hurricane barometric pressure and
its wind speed? It is somewhat proportional? An initial
look see of data indicates to me that it is. (So why were
Katrina's winds reported to be 145 mph when the bp was at 915 mb?)
I would suggest collecting public advisory data on as many hurricanes
as possible. Chart the bp fall with the wind increase to see if
the graphs are proportional. Hurricanes advisories are issued at
6 hour intervals. (3 hour intervals when in close proximity to
the US mainland) You might also correlate this data with how far
hurricane and tropical force winds extend outward from the center in
these storms. (see if you can establish a pattern) As I am
typing this, Hurricane Rita - Category 5 - has just been reported to
have sustained winds of at least 165 mph with a bp of 914 mb.
Was Katrina the storm that did not follow typical trends? You
might consider the research. I have a few more thoughts on this
so if you decide to give this a try and need some help, drop me an
email.
-
Engineering
- And again on the subject of hurricanes......Hurricane Rita struck
southwest Louisiana. It was more of a wind storm vs. a rain and
storm surge system. In addition to the many trees felled by the
Category 3 hurricane, 90% of roofs lost some or most of their
shingles. I have heard different stories relating to the method
of nailing down shingles. Some say that if you use a hammer and
4 nails the shingles won't blow off. Some say that if a roofer
uses a nail gun then these staple like nails will not provide enough
fastening strength to keep the shingle on during high winds. I
believe the pitch of a roof also has a lot to do with whether or not a
shingle gets blown off or not. Set up a test "roof" in
your backyard using a sheet of plywood, felt paper, and some
shingles. Try the hammer and nail method as well as the nail gun
method. Also vary the pitch of your "roof". Most
old style roofs are 6 on 12. Many of the new style homes have a
9 on 12 or even a 12 on 12 roof. Is there a magic pitch that
will resist winds best? Do shingles put on with hammer and nails
stand up better than ones using nail guns? For WIND - use a
gasoline powered leaf blower. I have read that many of them
generate winds in excess of 75 mph. Some of the higher end
blowers are suppose to move the air in excess of 150 mph. If
this information were not available with the blower, then I am sure
you could contact the manufacturer. Added note - you would have
to secure the leaf blower in a controlled position - preferably
parallel to the ground at a preset elevation representative of how
hurricane force winds would blow. Also remember, hurricane force
winds sometimes lasts for 4 hours or longer, as they did for Rita in
SWLA. Have a gas can ready for quick refills. If
done right with much testing, (photos, video, etc.) this should be a
winning project.

Medicine
& Health - A while back I read an article about shops in
Europe that would play a high frequency sound, that only young people
could hear, to keep them from loitering outside their place of
business. This sound is apparently in the 17 khz range. As
people grow older, they loose the ability to hear sounds in the high
frequency range. Well, we all know that teens are not only
smart, they are very innovative. The younger generation seized
upon this sound and turned it into a ringtone. Eureka!
Their cell phone can ring in class without the teacher hearing
it. I have tried this ringtone on co-workers and the only one
that can hear it is someone in their late 20's. A good
experiment would be to test many different age groups - both male and
female - to see where the break point is for this sound. (at
least 100 test subjects would be needed to give good results) A
good testing time of day would be in the morning and a quite location
would be needed. If by chance you run across someone old like me
that can hear this "mystery sound", then try to get as much
health information as possible. (type of work they do, if they have
ever been exposed to loud noises, etc). You may find that one
gender looses that ability to hear in the high frequency range before
the other. I don't know but you may also discover that a human
doesn't develop the ability to hear this sound until a certain age.
(which would mean that you would have to test pre-schoolers). And then
why stop at humans - extend the experimentation to animals (dogs,
cats, etc.). You might discover that this sound keeps away
certain nuisance animals away from your home. I have
included download links below for this sound - both in MP3 and Wav
format. MP3 is of lower quality than wav. If you use your
cell phone for producing the sound, remember that it may not be able
to generate a sound in the 17 khz range. Using a iPod or
portable MP3 player would work. This would be a very unique
project and sure to win prizes if done thoroughly and with many test
subjects. (MP3)

Behavioral
& Social - Does birth order affect personality
traits? I recently ran across an article that address this
issue. If there wasn't so much evidence out there supporting
this I would have said no. But there apparently is data that
indicates there is a distinct possibility. If you go to the
following links you will get more information - (http://inst.santafe.cc.fl.us/~mwehr/genpsyc/FMBirOrd.html)
and (http://jrscience.wcp.muohio.edu/nsfall99/FinalArticles/Birthorderanddemographics.html)
If you wanted to get really creative and have the resources, apply
this same question to dogs or cats.
