Science Fair Projects - Why Does Fido Bark?

Science fair projects on animal behavior can be fun and fascinating! Watching how animals behave and recording those behaviors is known as Ethology. Animal behavior is a branch of the science of zoology. Studying what animals do in their natural environments help to better understand them. This knowledge can be helpful in learning how to share our world with them and help protect their environment so they can thrive. For animals that are in danger of dying out, known as endangered, animal behavior studies help to increase the number of endangered animals.

One animal that has been the focus of many animal behavior studies is the gray wolf. These wolves were once abundant over much of North America but because of widespread destruction of its habitat; in some regions it is endangered or threatened.

One of the most fascinating areas of animal behavior is to watch the body language of animals. It's interesting to note that many of these behaviors are similar to dogs and can be exhibited in our own pet dogs. Look over this list of gray wolf body behavior-have you seen dogs do any of the same things?

Body Language

Wolves communicate visually through a wide variety of expressions such as a slight shift in weight or rolling on their backs to indicate complete submission. Other visual ways they communicate are:

• Dominance - A dominant wolf stands with stiff legs and tall. The ears are erect and forward, and the hackles bristle slightly. Often the tail is held vertically and curled toward the back. This display asserts the wolf's rank to others in the pack. A dominant wolf may stare at a submissive one, pin it to the ground, "ride up" on its shoulders, or even stand on its hind legs.
• Submission- During active submission, the entire body is lowered, and the lips and ears are drawn back. Sometimes active submission is accompanied by muzzle licking, or the rapid thrusting out of the tongue and lowering of the hindquarters. The tail is placed down, or halfway or fully between the legs and the muzzle often points up to the more dominant animal. The back may be partly arched as the submissive wolf humbles itself to its superior; a more arched back and more tucked tail indicate a greater level of submission.
• Submission- Passive submission is more intense than active submission. The wolf rolls on its back and exposes its vulnerable throat and underside. The paws are drawn into the body. This posture is often accompanied by whimpering.
• Anger - An angry wolf's ears are erect, and its fur bristles. The lips may curl up or pull back, and the incisors are displayed. The wolf may also arch its back, lash out, or snarl.
• Fear - A frightened wolf attempts to make itself look small and less conspicuous; the ears flatten against the head, and the tail may be tucked between the legs, as with a submissive wolf. There may also be whimpering or barks of fear, and the wolf may arch its back.
• Defensive - A defensive wolf flattens its ears against its head.
• Aggression - An aggressive wolf snarls and its fur bristles. The wolf may crouch, ready to attack if necessary.
• Suspicion - Pulling back of the ears shows a wolf is suspicious. The wolf also narrows its eyes. The tail of a wolf that senses danger points straight out, parallel to the ground.
• Relaxation - A relaxed wolf's tail points straight down, and the wolf may rest sphinx-like or on its side. The wolf may also wag its tail. The further down the tail droops, the more relaxed the wolf is.
• Tension - An aroused wolf's tail points straight out and the wolf may crouch as if ready to spring.
• Happiness - As dogs do, a wolf may wag its tail if in a joyful mood. The tongue may loll out of the mouth.
• Hunting - A wolf that is hunting is tensed, and therefore the tail is horizontal and straight.
• Playfulness - A playful wolf holds its tail high and wags it. The wolf may frolic and dance around, or bow by placing the front of its body down to the ground, while holding the rear high, sometimes wagged. This resembles the playful behavior of domestic dogs.

For those who love animals, Ethology, or the study of animal behavior, is an exciting zoology science. If you love animals a study of your favorite pet or animals around you would make a great science fair project.

How about studying the behavior of the common household cat-what behaviors does your cat exhibit and why. How about a science fair project on birds-can you determine the type of food a bird eats by looking at its beak? How about a science project on Fido-what type of foods do dogs like best? These and other animal behavior observations could make great winning and fun science fair projects!

Much Agog About Turning Water Into Fuel

There's a new craze in cyberspace, where a lot of people are showing off their ingenuity of turning simple tap water into some sort of a re-invented fuel. That's good, sign of the times.

As in this age of global warming and climate change, the continued use of fossil fuel into its derivatives- causing pollution and it's potential depletion may have brought about this Earth's chemical and electro-magnetic imbalance.

So, it might pay for us to encourage the use of water for fuel, and considering that it may face stiff oppositions from oil magnates and oil-revenue hungry government, maybe we should startadapting to it within ourselves.

Anyway, no one can claim he invented water for fuel, because it is natural and universal science. Actually, the process of turning water into molecules of oxygen and hydrogen by passing it thru an electrical current and then channeling the explosive gas of hydrogen aided by oxygen gas into fuels for combustion, has long been proven.

Water to gas fuel is today's innovation, as it was the English Chemist, MICHAEL FARADAY, who first investigated it as ELECTROLYSIS. Where, after many careful experiments, he stated the following three "laws":

1) The ability of an electric current to cause electrolysis does not depend on the distance between electrodes.

2) The quantity of a substance that is electrolyzed is also proportional to the quantity of electricity used.

3) The quantity of a substance that is electrolyzed is also proportional to the substance's chemical equivalent. The chemical equivalent of a metal is it's atomic weight (in grams) by it's valence.

Faraday found out that approximately 96,500 coulombs of electricity are required to electrolyzed one chemical equivalent of any metal.

The number of coulombs that flow in each second is measured in Amperes. And Voltage is like an electrical pressure that pushes the coulombs through the circuit. In electrolysis, voltage is just as important as amperage.

A certain minimum voltage is needed to produce electrolyisis in any given time. For example, a minimum of 1.23 volts is needed to electolyze water to hydrogen and oxygen at 25 degree centigrade.

So, just from here anybody can expand and upgrade their own "water to gas for fuel" experiments and have their own portable water fuel station. Then who can beat that, we have to save this planet, you know.

Physics Problems And Method Of Questions - Efficient Learning Method

How should we learn? How can we learn in the most efficient way?

We do not want to spend a lot of time to understand the new science topic, but we finally want to understand it.

One of the most difficult science fields is physics. Many students are afraid of physics, they read physics books, but they do not understand them.

Some students can solve simple physics problems, but they cannot solve the more difficult ones. What should they do?

There is a special method how to improve the problem solving skill. This method is called method of questions.

The idea of this method is the following.

To understand physics we need to solve as many problems as possible. Each additional problem gives us some additional understanding of the basic concepts.

Therefore we need to solve a lot of problems. Of cause, some of them are difficult and we cannot solve them.

In this case we need to start from the problem we can solve. It can be a simple problem or a complicated one. It does not matter.

The most important is that we can solve this problem and we understand how to solve it.

Then we modify the problem and we ask the questions. It means that we apply the method of questions.

Since we know how to solve the original problem then we can solve the modified problems.

In such way we can solve many problems for the shortest amount of time.

The application of the method of question can save a lot of time in your physics learning process.

You can find more information about the method of questions and other approaches to physics learning at the website: http://www.solvephysics.com
