Quick and Easy Science Fair Projects

There are a lot of quick and easy science fair projects around these days. However, this is a kind of project that is in reality very simple, but it is also quite attractive and out of the ordinary. This particular project involves magnetism. You just need to arrange for the magnets. The rest of the items are quite easily available. Look around the house and you will find plenty of them.

The ingredients needed for performing it are as follows:

- A few toy cars preferably four toy cars made of plastic.
- Donut magnets get double the number of donut magnets as the number of cars that are being used. In fact, the more magnets you use, the better the results are going to be.
- Elongated cardboard case, preferably the type used to hold tubelights.
- Cellophane tape and scissors.
- Thermocol.
- Colored paper and other toys for decorating the set-up.

The first step is to find out which poles of the donut magnets are similar poles by bringing each magnet close to one magnet set as a standard. Once you have located the same pole in every donut magnet, fasten the magnets to the toy cars using cellophane tape in such a way that the same poles face outward.

Now for the tracks make a latitudinal section of the cardboard case. Only one half shall be used for the experiment. It should have the same width as that of the toy cars, and be around a couple of meters in length. Now arrange them at a slight angle (approximately 3~5 degrees) to the horizontal plane using the thermocol. Attach a block of thermocol at the bottom as a dead end. At the top, leave around thirty centimeters of the track parallel to the horizontal plane. Line up the cars one by one. Place blocks of thermocol at regular intervals along the track in order to provide support to the entire set up. Also, make sure that the sides are vertical. Otherwise, the cars might fall over.

Now roll one car at a time to the track and release it. They will reach the bottom. However, adjacent cars would never touch due to the repulsive force created by the similar poles of the magnet, and you will observe a spring-like effect each time a car approaches the previous one.

This quick and easy science fair project can be decorated using the colored paper and toys. It illustrates the fact that the like poles of two magnets repel one another.

The Giant Green Iguana

The giant green iguana is likely the best pet of the entire iguana family because it is the easiest to tame and does not show aggression in captivity as strongly as many of its relatives display. The giant green iguanas are generally acquired from a hot and tropical location and require very precise living conditions while in captivity or they can die a very horrible death. In order to house your reptile properly it is essential to understand and be able to provide the housing conditions in which it requires to sustain a good quality life.

Housing Conditions

The giant green iguana is a wonderful pet to own however there are some considerations to take into account before deciding if you can properly house one or not. It is no surprise that the giant green iguana gets it name because it tends to grow to quite large sizes and in fact can grow to weigh more than 20 pounds and can grow in length up to six feet long! It is also necessary to consider when deciding on a giant green iguana that the life span of these reptiles are typically anywhere from ten to fifteen years. That is a very long commitment to take on when deciding on a giant reptile for your house pet. It is one of the most serious problems with giant green iguanas because a lot of potential owners think that they are very cute when they are small but they grow to be very large and the owners decide they cant house the iguana that it has grown to become.

It is also imperative to know when deciding if a giant green iguana is the pet for you that it is a particularly good pet for children to be around for a variety of reasons. The first and probably most important that most potential owners overlook is that iguanas tend to carry salmonella on their skin. People that handle these creatures should be diligent in hand washing to avoid being sickened by the salmonella and children are not very disciplined in doing these things and as a result tend to fall ill to salmonella poisoning.

The giant green iguana holds yet another reason that children are not a good owner of these reptiles is because children have a way of scaring the iguanas by jumpy moves and not speaking softly as they tend to get excited easily as do the giant green iguanas and that wont make for a good situation and the iguana will get very aggressive and mean with the children.

Goodbye Animal Testing - Hello Health By Biochips

When you receive the Seal you will begin to care both about your health and about the environment. A new technology promises that a lot of animal testing can be eliminated and at the same time make it much cheaper for new drugs to come to market.

The new technology involves biochips, the MetaChip and the DataChip. These biochips act just like the body act when it takes a drug. They will be able to show whether there are any toxic side-effects of taking the drug. As high as 70 percent of new drugs being developed have to be scrapped because they are toxic to the body. But this is not discovered until after each drug cost hundreds of millions of dollars in research money.

These biochips promise to eliminate all that wasted cost in drug development. And they promise to eliminate much of the unethical experimenting currently done on animals. The European Union has banned all such testing on animals and that is set to begin in 2009. At that time there will be quite a market opened up for the biochips.

The biochips are glass slides dotted with tiny droplets of enzymes from the human body. The MetaChip has liver enzymes. It can show whether a drug is toxic to the liver. The DataChip contains enzymes from the bladder or kidney as well as the liver. Those can also be tested for toxicity. And if there is any toxicity it will be found much earlier in the drug trial process, saving huge amounts of money.

Animal testing is not just unethical. Its accuracy is also dubious. There is always a question of whether humans will have the same reaction animals have. It can give a general idea, but nothing specific enough.

The biochips show how humans will react. And yet what is being developed now is still not specific enough of testing. The researchers have big dreams for biochips, including "personalized" testing. In the future, every sick person can have his or her own biochips made from enzymes from his or her body. That way drugs can be tested for their reaction with that individual person, not for all people in general.

This heralds and important development in medicine--the "personalization" of medical treatment. In the future drugs can be chosen and even developed for individuals or smaller, more specific groups of people. Drugs currently are developed for everyone and anyone. And that is not good. People vary widely in their genetics and predispositions to disease. Their chemical make-ups are different. So why not treat them differently, since they are different?

That is what this new technology promises, although we are not there yet. This is only the beginning. Another dream researchers have is the dream of including more organs in the biochips. In the future all the organs can be tested, including the heart, the brain, and the skin. This will give a more holistic picture of the reaction of the body of a person to a particular drug.

When you are sealed you will begin to notice your health and the environment too. God will show you how to both extend your life and take care so you do not destroy the earth when you receive the Seal.

Are These Facts Or Shark Tales?

The term shark itself is the source of several questions that pop into your head. Many people are not sure if some statements are based on facts about sharks or simply some common shark tales. Which is why the main question that is usually on peoples mind is: Are these facts or shark tales?

Lets find out about common shark tales that are surrounding some popular shark tales. For example, one shark tale is saying that all sharks must swim to breath and stay alive. In fact, while this statement is partly true as most shark species do need to keep swimming to be able to breathe and avoid drowning. Some species such as lemon, nurse and bull sharks can rest at the bottom of the ocean and keep breathing by opening and closing their mouth and filter the water through their gills.

Another one of the shark tales is the statement that all sharks are potentially harmful to humans. In fact, of the 350 shark species, 80 percent of them are either incapable of harming humans or unlikely to ever being in contact with them.

A third one of these shark tales is the statement that all sharks eat anything. In fact while some species will eat just about anything like in the case of the tiger shark which will even eat license plates, canned goods and even shoes, most shark species will in fact prefer to eat fish, mollusks and crustaceans.

The fourth statement that is part of the shark tales is the one stating that the larger the shark, the larger the prey. The fact is that the two largest sharks are in fact consuming the smallest prey which is plankton. These sharks are known as the basking shark and the whale shark.

Some people also believe one of the shark tales being that sharks need to bite their prey sideways. The fact is that a shark can attack its prey from any angle. Since their unique jaws can even protrude beyond their snout, sharks can catch a prey that is in front of them.

A common statement made amongst shark tales is the one saying that sharks eat each other in the womb. Well, in the case of the sand tigers, one shark in each oviduct will feed on its weaker siblings until birth but it is not the case in most shark species.

Amongst shark tales, you also find the belief that sharks only have five senses like us to find a prey which are: sight, hearing, smell, taste and touch. In fact, sharks can also use two other ways to detect a prey. They can feel their electric field as well as the vibrations linked to their movements.

While several merchants are selling shark cartilage pills and the belief that they can prevent and cure cancer, these beliefs are considered shark tales as there is no proof as of now that these pills have these properties. These affirmations are mainly based on the fact that no sharks so far have been showing signs of cancerous tumors but nonetheless, it is not a proof that they are immune to cancer.

It is the common belief that a sharks eyesight is very poor. In fact, it is quite the opposite as the lenses in their eyes are 7 times more powerful than the human eye. Some species can even see a light 10 times dimmer than the dimmest light perceived by the average human eye.

Finally, the last one of the shark tales that I will share with you is the one stating that if you must fend off a shark, punch it in the snout as hard as possible. Well, the experts actually advise you against such action. While this technique proved to be lucky for a few, it will mostly make the shark more aggressive. It is highly recommended to use a stick or a tool instead of your hands and poke the shark in the eyes or in the gills.

My name is Sylvie Leochko. I have noticed through the years, that since the appearance of Jaws on the silver screen, people have been given pretty bad advice that is based on shark tales instead of facts about sharks. Such advice could be deadly if used during a shark attack. If you wish to learn more about shark tales, I recommend that you visit this main page: http://sharks.findoutnow.org/shark-tales.html

The Wave-Like Properties of the Electron and the Scientific Proof

Electrons are particles spinning and revolving around the nucleus of the atom similar to the earth rotating on its own axis as it also revolves around the sun. This rotation, like that of the planets, is realised ceaselessly and in perfect order on paths we call orbits. Yet, the proportion of the size of the earth and the sun is very different from the atomic scale. To make a comparison between the size of electrons and the size of the earth, if we enlarge an atom as big as the earth, the electron would be in the size of an apple.

Tens of electrons revolving in an area so small as to be invisible even to the most powerful microscopes create a very complex traffic inside the atom. The most remarkable point here is that these electrons surrounding the nucleus like an armor of electrical charge do not have even a small accident. In fact, any small accident inside the atom would cause a disaster for the atom. However, such an accident never takes place. The whole operation runs flawlessly. The electrons revolving around the nucleus at the mind-boggling speed of 1,000 km/second never collide with each other.

It is extremely amazing that these electrons, which are no different from each other, follow separate orbits, and it is obviously the result of a conscious creation. If they had different masses and velocities, it might be natural for them to settle in different orbits around the nucleus. For instance, the order of the planets in our solar system follows this logic. Planets that have totally different masses and velocities are naturally settled in different orbits around the sun. But the case with the electrons in the atom is totally different from that of these planets. The electrons are exactly alike but have different orbits around the nucleus: how do they follow these paths unerringly, how do they not collide though they have incredibly small dimensions and move at incredible speeds? These questions lead us to a single point: the only truth we face in this unique order and delicate equilibrium is the perfect creation of Allah (God).

Electrons are small particles, almost two thousandth the size of neutrons and protons. An atom has the same number of electrons as protons and each electron bears a negative (-) charge equal to the positive (+) charge borne by each proton. The total positive (+) charge in the nucleus and the total negative (-) charge of the electrons cancel each other and the atom becomes neutral.

When electrons were first discovered, they were thought to be particles like the protons and neutrons found in the nucleus. In the experiments that followed, however, it was discovered that they display wave characteristics like light particles, that is, photons. Subsequently, quantum physicists came to the conclusion that every particle is simultaneously a wave form with its own distinct frequency.

The most significant experiment revealing the interesting nature of the sub-atomic particles was the double-slit experiment. This was conducted to see how light and electrons both behave like waves, and how they both manifest this surprising feature to the same extent.

In order to gain a better understanding of the subject, assume that this experiment was conducted with grains of sand rather than electrons.

First, bring a source of sand grains, such as a sand-blower, behind a wall. Let there be two slits in the wall. And let there be on the other side of the wall a screen to detect the particles passing through these slits. Each sand grain impelled by the blower travels through one slit and strikes the screen.

Once a large number of grains have passed through the slits and hit the screen, we see that two clusters of points have appeared on the screen; one made up of grains passing through the first slit, and the other of those passing through the second. Events have transpired as we expected.

Now, imagine that we have conducted a similar experiment in a different way. Let us fill the experimental environment between the source and the screen with a pool of water, and use a vibrating object instead of the source of sand particles. This object sets the water in motion and continuously generates waves, spreading in all directions.

Unlike grains of sand, these waves are not localized in space. They are spread throughout the whole pool. As a result, the waves passing through both slits simultaneously spread out, encounter one another and interfere with each other.

When the crest of one wave combines with the trough of another, they neutralize each other. The wave effect disappears, leaving nothing. This interference is a basic characteristic of waves.When the experiment was performed with electrons, instead of a cluster of particles striking the screen-as with the sand grains-the electrons were observed to interfere with one another. The expected result failed to occur if the electrons were regarded as particles only. Therefore, since the electrons displayed the wave-like feature of interfering with one another, they cannot be particles. Yet they cannot be waves either-because, just like particles, they struck the screen in discrete groups.

In this instance, the observations suggest that the electrons are localized particles when they leave the source and when they arrive at the screen, but that they act as waves everywhere in between. This is really very counterintuitive.

This experimental evidence did away with materialism, according to which, every particle must possess an objective existence somewhere in space. Again according to materialism, an electron must follow a single course through a space and cannot move through both slits like a wave which is not localized. Yet materialists' expectations did not correspond to experimental reality.

The wave we are referring to here is different from a physical wave that occurs in water. Electron waves do not exist in the three-dimensional space in our physical world.

Fred Alan Wolf describes the wave concept in question:

When quantum physicists determine the probability of an event, they calculate a number. This number arises from the multiplication of two mathematical functions called quantum wave functions-or, as I call them, qwiffs. Qwiffs are imagined to be real waves moving through space and time. However, they are not real waves; they are purely imaginal. They are not fields like magnetic fields or gravitational fields. They cannot be measured. They have neither mass nor energy. They exist in our minds and imaginations. That is, they do not exist as we observe real material things existing. . . . The dynamic laws governing time loops bring a story into being. In other words, when a time loop is created, the world we commonly and uncommonly experience as "out there" arises both in our minds and in what we believe is objectively shared reality. (Fred Alan Wolf, Mind into Matter: A New Alchemy of Science and Spirit, 2001, Moment Point Press, p. 105)

According to Wolf, the definite scientific truth regarding electrons cannot possibly be comprehended in terms of known physical or mathematical concepts. In any case, however, we are never in direct contact with the realities in the outside world. It is impossible for us to step beyond our own perceptions.

The double-slit experiment can be repeated with all sub-atomic particles. The results will always be the same, because quantum mechanics rules the entire universe. True, when billions of atoms combine to give rise to any large object or a human being, the probability of this interference effect ever being observed decrease sharply. But this does not mean that the laws of quantum physics have ceased to apply. This process is now just not observable. Therefore, this fact applies to all of matter.

According to the Washington University mathematician Thomas McFarlane, the large objects we encounter in our daily lives are not objectively existing matter, either. According to him, the appearance of an objectively existing world independent of observation is an illusion.

What quantum mechanics has scientifically proven is that the objective world exists in a concentrated wave form. According to physicists, the main problem that misleads people is that the world observed through our perceptions is high in convincing detail, sharpness and clarity. Yet the outside world never actually reaches us. We can never see the external reality, the original of the material world existing out there.

Our daily lives present an image highly inconsistent with the external realities. Therefore, the question arises of which one-whether the physical reality or what appears to us so sharp and clear-should be regarded as valid.

Thomas J. McFarlane states that the answer can be found by drawing a comparison.According to him, we can imagine modern-day scientists going back 3000 years in the past and meeting with people who imagine the Earth is flat. The scientists politely tell them that they are in error on the subject, and that the Earth is actually spherical.

These people then ask the scientists, how could you have come by such an insane idea? The scientists will be unable to provide a single piece of evidence to prove their thesis, under the conditions and state of knowledge of that time. They, on the other hand, are quite capable of explaining that the Earth is flat, on the basis of all their experiments and the evidence they've gathered. They use the concept of plane geometry to measure out land and chart road maps, and find nothing in this that conflicts with their daily experience. In the same way, when they look at a wide open expanse or the sea, they say that they can see no curvature and so claim that there is no evidence showing that the Earth is round. The idea that The Earth is round thus remains a delusion. The scientists return to their time machine and to the present day, without having proved anything.

According to McFarlane, the reason why these time-travelers were unable to convince anyone the Earth is round is that we humans are so very small in comparison to the Earth. Since our experiment is confined to a geographically very small area, the Earth appears to be flat, even though it is not actually so. In other words, the flatness observed on Earth is not a true flatness at all, because the Earth is not flat. This is only an illusory flatness caused by the immense size of the Earth.

In order to prove that the Earth is round, we need to go beyond our day-to-day limitations. For instance, we could fly around the world in a plane, or we could go up into space in a rocket. But when limited to our day-to-day experiences, we have no evidence that the flatness we perceive is an illusion. Similarly, we have no reason not to believe that the Earth is flat.

After citing this example, McFarlane goes on to say:

If people have been so deluded about reality in the past, how can we be so sure that we are not deluded now? As we have seen, just because our present notions of reality are consistent with our ordinary experience, does not make them true. Since our experience certainly has its limits, perhaps our idea of the objective world really is an illusion, just as much an illusion as the idea of a flat Earth.

Allah created every 'where' both that which we are able to see and that which we cannot, with boundless artistry and He gave innumerable favours to be at our service, whether we are aware of them or not. It is undeniable that scientific development and progress ought to cause everyone who uses his wisdom and conscience to believe in the existence of Allah. Nonetheless, people still exist who ignore the superior artistry and wisdom observable at every point in the universe.

As a person learns more about the examples of creation surrounding him, he grasps much better that Allah encompasses him from every direction, He directs all affairs in heaven and Earth, and holds everything under control. He understands that his life will certainly be taken and he will be answerable for everything he has done on Earth. As a believer becomes more acquainted with the innumerable phenomena taking place around him, his admiration for Allah's knowledge increasingly grows. This admiration is a very important step on the way to perceiving the infinite power and might of Allah as much as possible and fearing Him as required. This is stated in the Qur'an:

Do you not see that Allah sends down water from the sky and by it We bring forth fruits of varying colors? And in the mountains there are streaks of white and red, of varying shades, and rocks of deep jet black. And humanity and beasts and livestock are likewise of varying colors. Only those of His slaves with knowledge have fear of Allah. Allah is Almighty, Ever-Forgiving. (Surah Fatir: 27-28)
