There are many types of water snakes found in the world. The type of snake you encounter depends on the region in which you are traveling. You should know that a snake could strike you from a distance of half of their body length. Hence it is safe to stay at a distance more than half of their body length. This striking distance is only when you encounter the snake in land.

In water their striking distance is very limited. Better avoid the areas in which the snakes sun. Usually they will be sunning in the branches that protrude over the waterfront so that if they find any encounter they will drop themselves into water and escape. That is why when you are canoeing you have to be careful when you move into the low-lying areas where branches of trees protrude over the waterfront. Some of the common water snakes that you might come across are the northern water snakes, red belly water snakes, banded water snakes, cottonmouth snakes, and the brown water snakes. The northern water snake is usually 22 to 59 inches in length and is found in the lakes, streams, rivers, marshes, swamps, ditches, and ponds. It is thick bodied and has a dark band around its neck. You can find half moon spots in its belly. It is found in the central and eastern US. Usually they come out in the night.

The cottonmouth water moccasin is a poisonous snake, which is also aggressive in the sense that it will approach the intruder in the area. It is semi aquatic in nature. Usually they lie on the water logs with part of their body in water waiting for their prey to come within their reach. This kind of water snake could be having a dark body color and a light belly color. It might also have body cross-bands. When this snake bites you it would latch on to the area with its bite rather than the bite and release pattern found in the other snakes. It has a powerful jaw. Some of the subspecies of this water snake include the eastern, western, and the Florida cottonmouth.

The brown water snake is usually active during the day and rarely hunts during the night. Fishes and frogs constitute its main dish. It also climbs the branches to sleep on the overhanging branches over the water. It usually escapes when you frighten it and if you need a bite you can catch it! It is usually found in the southeastern U.S. The Diamondback water snakes have a chain like pattern in its body and have a yellow belly. It is found in the marshes, swamps, and the lakes of south central and southwestern U.S. they have long teeth and hence the bite from these snakes would be more painful.

John Koza has made a serious breakthrough when it comes to the computing power of today and our hopes for it in the future. Studying computers since his high school tutelage in the 1950s, Koza was a man who yearned to make advancements in the world around him. As a clear example of his ingenuity, he was unable to afford a computer while in high school, since the mainframes of the time took up entire rooms and cost far more than the modern day computer. To that end, John assembled bits and pieces from the gadgets around him, and with parts from old pinball machines and jukeboxes, he found himself with a computer that could accurately compute what day of the week a certain date would fall on.

John's latest invention far surpasses his date-decoding computer of the fifties. Utilizing 1,000 networked computers operating in tandem, his new device uses genetic programming to solve problems. Essentially, what the machine does is follow Darwin's laws of survival of the fittest - it compiles code, tests it against other code, and thereby determines the most accurate usage of code. And the machine wasn't built with one purpose in mind; instead, it utilizes it's thinking' process to solve complex engineering problems of manufacturing and production of whatever you can think of. And it does it arguably more efficiently than a human. The machine is well within operating conditions, as Koza has already made an engineering breakthrough with it. Most recently, the machine has come up with a type of lens system that can be used in telescopes and binoculars that offers a better field of vision than any type of lens created before then, and it does not infringe on any patent. To perform this feat, the program generated 75,000 random types of lenses. From there, it mated' the designs, taking the features that were helpful in one and placing them with features that were necessary in another. From there, generation after generation is created until every part of the design specifications is met. For the lens, the machine processed 295 generations before reaching a final solution. The machine has been proved useful in other inventions, as well. This heralds a scientific breakthrough in which computers may soon be doing much of our thinking for us. The machine has already received the first patent given to a non-human entity, and the sky is the limit.

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.

Many teachers agonize about planning science lessons for Grade 1. They think that the students are too young to take part in science experiments. This is because they associate science experiments with using chemicals and Bunsen Burners. At this grade level, there are many experiments you can do in class with the students that are perfectly safe and do not put the students in any danger.

For example, it is easy to plan a lesson related to using the five senses. A taste test, or an experiment where the children are blindfolded and have to identify certain foods by the way they taste, smell and feel, is perfectly acceptable. The only precaution you would have to take in this type of lesson is to make sure that none of the children have any allergies to the foods you plan to bring into the classroom.

To teach the concept of using the sense of hearing, it is quite easy to make a tape recording of certain noises and see whether the students can identify them. In order to evaluate the lesson to see whether or not the students have achieved the objective, you can have them draw a picture to tell what they learned, retell it to you or have them write a sentences in their journal or learning log.

If you wish you can also have the students create noises of their own using materials that you bring in, such as scraping a comb over glass or the sound of chalk on the chalkboard. Many of the activities that you use with science lesson plans dealing with sound will also achieve the objectives for your music curriculum as well, so you might want to work with the music teacher on this section.

Some of the outcomes that you need to address in Science lessons for Grade 1 are:

1. Students will be able to identify the five senses

2. Students will be able to demonstrate ways that materials can be used to alter their smell and taste

3. Students will demonstrate ways we can use materials to make different sounds

4. Students will describe ways in which materials can be changed to alter their appearance and texture

5. Students will demonstrate how each of the senses helps us to recognize, describe and safely use a variety of materials.

You can teach all of these objectives using fun activities to keep the students interested. You have to think of the age of the students and realize that these activities are very simple, yet relevant to students in Grade 1.

What kind of activity could I use to teach Objective 3 Students will describe ways in which materials can be changed to alter their appearance and texture? You have to keep in mind that you dont have to get the students to do all the experiments. You can do some with them watching and then ask them questions about what happened. For this objective, you can take a piece of paper towel. Pass it around to all the students so that they know what it looks and feels like. Soak it in water and then show the result. Students can immediately see how the appearance and the texture of the material have changed.

When you are teaching Science lessons in Grade 1, you should always look for appropriate childrens literature so that you start the lesson off with a story to peak their interest.

How Paper is Made by Arthur Lockwood is a good book to use for this lesson because it describes the changes in the appearance of a tree from the time it is cut down until it is made into paper.
