Today we had a very cool exercise with water in Dr. Boyd’s class. We all tried to make a needle to float on the water. That didn’t work out so well considering that the needles weren’t exactly straight. This is called surface tension.
Surface tension is a property of the surface of a liquid that allows it to resist an external force. (http://en.wikipedia.org/wiki/Surface_tension). In other words, it allows something to rest on top of the liquid. This is all possible because of the teamwork of other molecules. Many bugs are able to sit and run on top of the water, such as water striders. Another example of surface tension is competition diving. In the video I'm going to show you, notice the water spraying into the pool. The purpose of this spraying water is to reduce surface tension, that way there is a less impact on the diver.

5 great paper airplane designs

You might think of them as child's play, but there's a surprising amount of history behind paper airplanes.

Thought to have been invented by the Chinese several thousand years ago, these useful toys have helped guide some of history's most famous aviators. Leonardo da Vinci built them to test his ornithopter. The Wright Brothers used them to prototype their historic Flyer. During the early part of the 20th century, designers at Lockheed and Heinkel put them to work in the development of new warplanes.

But today, even with the benefit of modern aerodynamics, physics, and materials, the creation of a good paper airplane is still as much art as it is science. Grab a stack of 8.5" x 11" paper, find a clean, flat surface, and get ready to fold. Here are five of our favorite flying wonders.

The Record Holder
Where better to start than with a world record holder? Florida resident Ken Blackburn used this design to set the world record for paper-airplane flight time back in 1998, clocking an astonishing 27.6 seconds. Although Blackburn's record has been surpassed, the design is still superb, and it's surprisingly easy to make. Perhaps you can outfly him.

The Sabertooth
The cool split nose of the Sabertooth makes it a mean-looking contender. A little harder to build, it'll really help if you use paper that's marked on one side, just like in the video. The build requires you to flip the sheet over a number of times -- miss one and you'll probably get hopelessly lost. Or end up winging it.

The Cobra
Satisfyingly ingenious to build, the cunning design of the Cobra is made easy to follow by this clear video. Two concertinaed folds shorten the length considerably, adding plenty of weight up front, and the result is a clean-looking, classic snub-nosed plane that flies straight and true.

The Arrow
Can a paper airplane be classified as a weapon? Before you answer, try hurling The Arrow. Good for 30-40 feet of dead-straight flight, this slender projectile is razor sharp and worryingly effective. Don't shoot your eye out, kid.

The Spirit
Ready for something a little more intricate? Starting with a square-shaped piece of paper, the Spirit requires finesse in the last few steps, otherwise you'll end up with something that looks like a pig and flies like a cow. Get it right, though, and you'll be the envy of all your friends…as long as you have friends that are impressed with cool paper airplanes.


I remember doing a science project on paper airplanes in the sixth grade, I took five different disigns and see which one would go the farthest; very cool, very fun.

Diet crutches: What works, what doesn't.

Let's face it: The rules of weight loss—eat less, move more, treats in moderation— are a drag. And they don't fit with most dieters' quick-fix, thinner-by-dinner expectations. Cue diet crutches: tricks, based on scant science, that may speed up results. So if a friend swears that munching on grapefruit gets her into skinny jeans, or a coworker credits ice water for his sleek physique, should you try it too?Not so fast. Some diet crutches are helpful, some harmful, and some won't do much either way. We asked registered dietitians for the bottom line ("skip it," "try it," or "do it right") on the most common diet crutches.

After reading all of the 17 dietary cruches, I find that this is a great thing to incorparate into my life, it said things about water, skiping meals, drinking diet soda, ect.

The Nitrogen Cycle of an Underwater Aquarium

The cycle of which nitrogen is converted between a numerous amount of chemical forms, or as we commonly call it: the nitrogen cycle, is crucial for any life on Earth. Nitrogen is needed for growth and is common among air, ground, and water. Speaking of water, the aquarium of Earth is home to many aquatic animals and plants. Many people do seem to forget that there is chemistry even behind the aquarium. The nitrogen cycle of the aquarium is much like a natural filter to it.
Chemical processing, also known as natural fixation, are needed to convert gaseous nitrogen into usable forms for living organisms to live; which makes it quite important to the food production, whether it be in animals or plants. Nitrogen is around in an environment in a diverse set of chemical forms including organic nitrogen, ammonium, nitrite, nitrate, and nitrogen gas. Organic nitrogen may be found in the form of a living organism, or humus, and in the intermediate products of organic matter decomposition or humus built up. The nitrogen cycle of converting it from one chemical form to another has many of the processes done through microbes either to create and produce the energy or to obtain the nitrogen in the form needed for growth.
Nitrogen fixation must occur for the plants to use, it could occur from lightning strikes, but in most cases is done by free-living symbiotic bacteria. The symbiotic bacteria has the nitrogenase enzymes that combines gaseous nitrogen with hydrogen to produce ammonia; which is then further converted by the bacteria to make their own organic compounds, so the plant may live by those organic compounds which were produced for them to survive. Plants get nitrogen through their roots and from the soil they rest in, including aquatic plants. All nitrogen obtained by animals can be traced back on the food chain to eating plants, that of course have nitrogen, this is both land and aquatic animals. When an animal releases waste or dies, or if a plant dies, the initial form of nitrogen it leaves behind is organic. That allows itself to be formed to ammonium for other plants to obtain and then an animal to do so, then another, so on and so forth.
Nitrification and Denitrification both take place, as well. Nitrification is the process in which the conversion of ammonium to nitrate is primarily by soil-living bacteria. Due to their high solubility the nitrates can occur and enter at ground water. When underwater and creating algal , if too much, it can demand too much amounts of oxygen which can then lead to the death of other aquatic living organisms that require some of the water’s oxygen it withholds. Denitrification is the reduction of the nitrates , so an electron acceptor replaces the oxygen needed.
The aquarium of Earth is home to many living organisms amongst plants and animals. They can live in the water and survive off the energy, shelter, food sources, water, nitrogen, and water it can find underwater.  The nitrogen cycle helps the plants survive and grow, and intern supplies food for the aquatic animals. The stuff that is decomposed is helpful for the next that is to come. Every part of the nitrogen cycle is important for the aquatic life.
When learning all this information from wikipedia and aquarium and aquatic websites, I learned to appreciate the nitrogen cycle. I also enriched myself with knowledge I did not have before hand. Thus, giving even more appreciation for the chemistry we can find in our everyday lives almost anywhere. Whether we know it or not, chemistry is important, and it is there.

Chemistry Behind the Soap We Use(For Week2)

Imagine if no one showered or cleansed themselves each day with soap or didn’t wash their hands? Neither of those things would be possible without chemistry! There is chemistry with how soap cleanses us. Yeah, makes you really appreciate chemistry. If chemistry wasn’t around and we didn’t know how to use it we would not be able to create soap that was actually successful at cleaning. Chemistry stands behind many things in our everyday lives, one of which would include soap.
Soap is formed by molecules, the hydrophilic which looks almost like a “head” you could say and the hydrophobic chain that comes off of it. The hydrophilic head enjoys/likes water, where as the hydrophobic chain dislikes it. Due to this double team of hydrophilic head and hydrophobic chain, the soap molecules act like a diplomat, improving the relationship between that water and the dirt the water just could not get off alone! Therefore, when soap is added to water the hydrophilic head of the molecules stay in the water, while the long hydrophobic chain circles and entraps the dirt (to escape the water); which forms circular groups named micelles(electrically charged group of molecules) that absorbs the dirt. Then, an emulsion(suspense of something with liquid within another liquid) is formed, which means the dirt becomes suspended and dispersed into the water. The emulsions can then be removed by the rinsing and cloth materials. Thus, the general idea of how soap cleans.
When I read this article from a website with a Chemistry of Daily Life section I was quite amused to learn about how the chemistry used within soap to clean was. It certainly made me appreciate soap. Considering, I for one, do not want to be by someone who smells and is not clean. Therefore, chemistry I thank you for the kindness you do for my nose by cleaning the stench. The chemistry within soap is something I am happy to have in my everyday life.

Mt. Etna Releases Smoke Rings

Mt. Etna-the active stratovolcano, on the east coast of Sicily, has released smoke rings into the sky as of August 16, 2011. References I have are from the MSN News and they were recorded by male on video. It was released the day of the smoke rings and it does indeed impact our Earth by the gasses and chemicals it releases. I get my information from the video , a website , and wikipedia . All references were used as either proof/evidence, background information, or for chemical information.
Mt Etna is one of the most active volcanoes in the world. It is in an almost constant state of activity all the time! The fertile volcanic soils support extensive agriculture, with vineyards and orchards spread across the lower sides of the mountain and the Plain of Catania all the way to the south. Deemed by the United Nations, it is also one of the 16 Decade Volcanoes that should always be studied for further information; such as when an eruption may occur, how dangerous it might be, and -if need be- when to evacuate. This Volcano has eruptions often and recently. However it has an unusual characteristic of Smoke Rings. It is extremely rare and was first captured in the 1970s, then again in 2000 and 2011. As well as most recently, August 16, 2011.
Honestly, this had caught my attention. It did so for a couple reasons. The first reason, the one that caught me the most, was because it seemed highly interesting. What I mean is, the video thumbnail was still framed on an odd smoke ring in the sky. That then made me wonder what it was, so I checked out it’s title and short but to the point description to learn that it was from Sicily’s Mt Etna Volcano. I was then interested but began to wonder what chemicals are released from the gasses that Volcano had to release for the smoke and ring, as well as how could it impact our planet? So, I did some further research to learn it’s impact. I believe this video was quite a hook to peak my interest.
Beneath the Volcanoes surface the gasses are turned into molten rock but as it becomes active the gasses begin to rise and turn into smoke. This impacts our Earth and causes air pollution. When a volcano releases smoke it lets loose chemicals into the air we breath. It allows Sulfur dioxide (SO2), Hydrogen sulfide (H2S), Carbon dioxide (CO2), Hydrogen Chloride (HCl), Hydrogen Fluoride (HF). On August 16, 2011 all these chemicals were released into the sky above Sicily when Mt Etna released its Smoke Rings. I believe this impacts our Earth with its pollution, as well as how it impacts us to be careful and study this active volcano to be sure all can stay well for the people of Sicily.

Oxygen

I found an article about how much a plant can produce oxygen. Oxygen is produced by sunlight, carbon dioxide, water. Plants use around 1 percent of the sunlight hitting the leaves and efficient plants use 3 percent of the sunlight. There is a difference in how much oxygen is created from a plant. It is tested by the plant's photosynthesis rate which can be determined by measuring its oxygen production or carbon dioxide consumption. C3 plants are a type of plant that lives in cooler climates and produces oxygen at 45.9 G/M2. C4 plants have the maxium oxygen production of 57.6 G/M2 and is found in the tropics.

The article I believe was alright. It had the details and foundation necessary to explain how much oxygen can be produced. It also gave me some interesting facts. If I were to put it in numbers, it would be a six out of ten.

These studies could help place plants based on how much oxygen made or its look at how much oxygen created could be useful for going to another planet and colonizing.

Best Pizza Places in the U.S.

Top chefs and fabled bakers are among the new breed of pizzaiolo who are just as fanatic over the temperature of their ovens as how local their ingredients are. They're elevating pizza around the country from greasy pies in cardboard boxes to inspired creations with crackly, charred crusts topped with house-made cheese and charcuterie.
Here, we've chosen the best places for pizza around the country from new guard spots—including a Bay Area pizzeria that uses locally milled flour—to the nearly century-old East Coast institutions started by the original pizzaiolo obsessives that loyalists still (rightfully) love.

I fell that pizza corporations aren't as good as the pizzerias, reason being the old term "Quality over quantity."

Paint

Paint has been around since the dawn of Man, from the early cave wall pictures to the ancient Greek pottery to the Italian Renaissance to Present day; paint production is of the same materials now as it was when they were first created by the cavemen. Pigments are what create the textures and colors of paint, pigments are solids that are grinded up into dust and formed into a liquid using a binder. Within all the vibrant colors that have been used over many centuries, paint is a compound that has many universal uses.

Pigments are special properties that incorporate color and texture into paint. Pigments are normally classified into two categories, natural and synthetic; natural pigments are divided into various clays, calcium carbonate, mica, silicas, and talcs, synthetic pigments normally include engineered molecules, which include calcined clays, blanc fixe, precipitated calcium carbonate, and synthetic pyrogenic silicas. Certain special pigments are used as well, such as hiding pigments which atribute to protection from ultraviolet light; examples include titanium dioxide, phthalo blue and red iron oxide. Another example of special pigments is fillers which increase the thickness of the paint ultimately creating a greater volume and a more stable structure; cheap materials are normally used as fillers, such as diatomaceous earth, talc, lime, barytes, clay, etc. Some pigments have been known to be deadly; the greatest example would be lead, which is used in lead paint, for obvious reasons lead was soon replaced with titanium dioxide. Even though pigments are widely used, it is not the material that forms the whole structure; it is simply there to add detail.

Binders, the forming component of paint, also referred to as the only component that must be present and like pigments there are natural and synthetic binders, which include cement, alkyds, acrylics, vinyl-acrylics, vinyl acetate/ethylene, polyurethanes, polyesters, melamine resins, epoxy, or oils. Binders are categorized in accordance to drying or curing mechanism. A curing mechanism is an agent which causes polymerization, a chemical reaction that in term creates a three dimensional picture. Drying, to simply put it, refers to solvent evaporation, so curing and drying are two different processes. Depending on the chemistry of the components, some paints can undergo one or the other, sometimes both; thus there are paints that dry only, those that dry then cure, and those that do not depend on drying for curing. Paints that can simply dry contain a binder called lacquers, this is used when solvent evaporates where lacquers form a solid. Curing processes are caused by oxidative cross linking, catalyzed/cross linked polymerization, and coalescence. With all its chemical properties, paint has had a long history of creating vibrant images and imagination.

Paint dates back to the early Stone Age, where the first paintings were made on the walls of caves. Back then there were only six colors for which to use, lime white, yellow ochre, red ochre, umber, bone black, and carbon black, all of which are still used today. Paint was also used by the Greeks which were used to add color to their pottery; this was the same deal for the Romans since they were vastly similar to the Greeks. Other notable sites are Egypt, home of the pyramids where inside are hieroglyphics and many great painted treasures. Another site is the Italian renaissance, home of the famous painters Michelangelo Buonarroti and Leonardo da vinci. Michelangelo Buonarroti was a famous painter, sculptor, architect, poet, and engineer; one of his most famous feats was painting the ceiling of the Sistine Chapel. Leonardo da vinci was another famous renaissance artist who constructed the Mona Lisa, one of the most famous paintings in the world, which to this day is kept in the Louve located in France. Before the Modern age, paint used to be constructed by hand, but now with today’s factories paint production has increased sufficiently. Also in the modern time, paint has evolved into many categories; picture paint, which is used to create pieces of art as is paints history, home décor paint, which is used as a “do it yourself” manner, and spray paint, which is used to decorate cars and other vehicles, and is also used by notorious gangs in a manner of “marking territory”, this is commonly illegal as it is referred to as vandalism of public property. With its rich history, paint is defiantly a great asset of human existance.

With all the centuries that have passed, the vibrant colors of paint have many universal uses. From the chemical compounds of pigments and binders, to the great history that has revolved around the Stone Age to the modern times, paint is one of mankind’s greatest creations, and the only one to still be in use. I hope taking the time to read this has helped you better understand paint as writing this has helped me.

Swords

If anyone were to look at the time before gunpowder, swords would be a major tool of warfare. Swords have been used since ancient times. Many materials and ways to create swords have been made. Swords have not just been a weapon to mankind, but it also is used to symbolize justice, unity, aggression, etc. I'm here to explain what makes a sword including what metals are used, methods, and what truly makes a great sword.

Many metals and alloys have been used to create these weapons. The materials primarily used to create swords were copper, bronze, iron, and steel. The swords I listed are in the order of which the materials that the sword would be more effective starting at the very least. The effectiveness of a sword were based much of what metal or alloys were used. For example, If a bronze age sword of a spartan went against a steel or iron weapon and were tested on a pig for instance, the iron or steel would've had a much better cut than the bronze. Although workmanship would play an issue, the metals would've had a bigger factor. Although, some swords didn't just have a metal, but an alloy was used.

The two primary metal alloys used in swords were bronze and steel. Bronze is a mixture composed of copper and tin. This was an advancement since copper weapons would've not been this effective. Steel was a mixture of composed of iron and carbon. Although, a small amount of other elements would also be put in, it was primarily iron and carbon. This was also considered to be a better version of iron. Also, an interesting fact is that Carbon steel is made for the functionality of the sword in modern times or today. If a sword is used as decoration, it will usually be only stainless steel. Stainless steel is an iron alloy with chromium and other elements. Stainless steel is a corrosion resistant steel, so it would be able to stay good looking as a decoration. Many times a sword will be just as good as how it is made and the forging behind it.

The Metallurgy of Swords has two major ages, the Bronze and Iron. During the Bronze Age, obviously first copper than bronze came into use. The forging though was ineffective because it couldn't heated up to the correct or appropriate degree. Most of the time, the sword would become bent and the soldier using it would've had to bend it back to become any use again. During the Iron Age, iron became more of use around 1000 B.C.. Since iron was one of the most abundant elements, it was started to be used for weapons. Iron was usually found as iron ore, so in the forging process, the extreme heating of the iron ore would purify the iron. Then it would be smashed with sledges to purify in more to a purer form. Pure iron though is a little more effective than bronze, but not as much as the evolution process would think of. They were still pathetic weapons and it was difficult to have it stay sharp, but steel was a major game changer in swords.

Steel is the most latest type of metal alloy used for swords. Steel is capable of being flexible enough, but the carbon within it makes the steel hard enough to be kept sharp. Although the more carbon within the steel will make it more brittle. It is best to have a balanced amount that allows for the best use of the sword. The forging techniques of the sword and metal alloy or metal used may have a big factor in how well the sword would perform.

Swords are forever in history and its warfare. The materials and forging techniques may make the difference between a high quality or low quality weapon. Many would say that forging is an art. Swords aren't used in today's modern warfare, but It will always be a target for collectors and practitioners of any group that used swords.

Global Warming

Have you ever been to California? If you drive to San Diego, you will notice the

huge windmills when you first enter California. That is their way to reduce global

warming and use natural resources to power electricity. The way a windmill works is

the wind moves the blades and spins the generator to produce electricity.


Global warming is when the carbon dioxide builds up at the top of the atmosphere and

making the atmosphere like a blanket, and traps the suns heat inside.

http://www.nrdc.org/globalWarming/f101.asp?gclid=CJWlsZT626oCFfMZQgodYTiW8w

Gases contain the main product CO2. So by reducing the use of gas there will be less

global warming. I think the windmills are a very smart idea and should go

worldwide, same with solar panels and hybrid cars. These small little changes will

help shape our planet.

Lasix

Lasix

Horses are animals that are widely cherished through out the United States. Many people enjoy riding them, racing them, and competing on or with them. Horses, like humans, get sick though. In order to keep them healthy to perform the best they can, medical attention is needed. Inflammation and swelling are a major unsoundness, or fault in horses. Lasix can help that.
What is Lasix?
Lasix, or Furosemide is a medical tablet most commonly given to horses, specifically race horses. It is a diuretic, which means that it causes the kidneys to get rid of unneeded waters and minerals through the urine.
Why us Lasix?
Horses can easily suffer through excercie-induced pulmonary hemorrhaging, or EIPH. This means that when a horse is exposed to excessive activity, like racing, the plasma, or serum push on the lungs causing the capillaries inside to burst. This causes hemorrhaging, or bleeding inside the lungs, which is usually exhaled through the nostrils (since horse are unable to breathe through their mouth). Lasix stops this by depleting the liquids in the body, causing less pressure build up in the lungs. This depletes the likelyhood of EIPH to occur.
The Science behind Lasix
Furosemide can be ingested orally or injected to the inflammed area of the body. It goes into effect on cells such as erythrocytes and platelets, and in tissues including the ascending loop of henle, tracheal epithelium, and the smooth muscles of the body. It stops Chloride in its tracks of transportation into these cells. It does this by binding to the flouride molecules and injecting transporter proteins. In result, there is an accelerated shrinking of serum, and the serum concentrations of Chloride, Potassium, and Calcium are dwindled.
My thoughts
I got the information in this essay from three sources. I will explain to you why I chose these sources as I go through each.
http://www1.agric.gov.ab.ca/$department/deptdocs.nsf/all/hrs10688/$file/lasix.pdf I chose this site because of the research that was clearly done, yet the information given was easy to read and comprehend.
http://www.ivis.org/proceedings/aaep/2000/225.pdf I enjoyed this site due to the sophisticated wrighting it was put into. It sounded smart, and it still made sense to me.
http://www.youtube.com/watch?v=SCjXlT2BwOc&feature=related This video explains in brief detail the uses, effects, and side effects of Lasix.

OILS

Oils are everywhere. In your car, on your bike and motorcycles even food.

They help things glide more smoothly and have less friction. Without oils, all will

fail. I will be telling you about the different lubricants, the confusing “10w 30”

numbers on container, how chemistry ties in with oils, grease and chain lube. Oils

are what keep this world moving and not jam up.

For my dirt bike I need to use many different oils. Engine oil is the obvious one.

Engine oil makes the cylinder move up and down without slowing down. It just goes up

and down in a swift motion. Another is transmission. When you shift, you need it to

be a nice easy transition through the gears. Dirt bikes do not use transmission oil

except for Honda, which was a pain to change. Kawasaki, Yamaha, KTM, and Suzuki

actually use the motor oil and it works just fine. For suspension motorcycles need

to use fork oils. This simply helps out the front forks move without locking up. It

would be very bad if your forks locked up over a jump. It would be like hitting a

brick wall when you landed. The back spring does not require any oil. Chain lube is

used or should be used for every chain. Chain lube is used to make the chain glide

easier instead of a bone dry chain. If you do not use chain lube it could rust

really bad and eventually break off. The only problem with chain lube is that it

comes off so easily. You would have to put more on repetitively in order for it to

work properly. Some people use chain wax instead of chain lube. Chain wax makes the

chain last longer and goes through rain. But on the downside it’s really sticky and

is attracted to dirt and debris and is also really hard to clean off of your bike

because of the stickiness. So I would prefer chain lube. I searched and found most

of these answers from Wikipedia. Another type of oil used is grease. Grease is not

used much on dirt bikes except for on the axel and bearings. The axel grease reduces

friction on the wheels and makes them move more fluently. Bearings are little tiny

balls in a circle and they are placed on the axel to literally keep the ball

rolling. The bearings need grease to keep the little balls rolling inside. Another

type of oil I use is for my air filter. The air filter sucks in air, goes through

the air cleaner. Then, gas is added to the air to compress the cylinder and fires

the spark plug. Back to the point, I need to clean the air filter in order for the

dirt not to clog the air intake. After you clean it you need to spray air filter

oil on it. It’s kind of like a sticky, slimy substance. The sticky gunk collects the

dirt and loose debris so it doesn’t go through your air intake. You should always

clean your air filter in order for your engine to work properly. Another thing that

needs your engine to work properly is the type of oil you use. Do you ever wonder

what the “10w 30” on the bottom of your oil mean? Well the 10 and below numbers mean

it is really light and flows easily. You would use these types of oils if it is cold

outside. The “W” has two meanings; one is how much the oil weighs. Another is that

it will be able to work in cold weather as well. So if it’s normal outside you

would need thicker oil like a 20w 50. It is thicker but it works just as good in

cold climates as well. The second number is how hot the engine needs to be in order

for that oil to work properly. I got these from: http://abcnews.go.com/Technology/story?id=119270&page=2. I liked this guy because it

sounded like he did his research well.

How does chemistry tie in with all of this? Oils contain all of these compounds:

• Alcohols
• Aldehydes
• Esters
• Ethers
• Ketones
• Phenols
• Terpenes

I got the list from http://www.therealessentials.com/chemistry.html. I thought this

site was very reliable to use on my essay.

By now you should know all about the oils I use on my dirt bike. We need to use

motor oil, fork oil, transmission (for the Hondas), chain lube and chain wax,

greases and we finally learned about the numbers and how it ties in with chemistry.
