A water wheel changes the energy of falling water into mechanical energy that can be used for machines. The water is directed into the wheel through a tube. The wheel is placed on an axle, which is connected by gearing with the machine it is to operate. There are two types of water wheels, vertical and horizontal. The vertical wheels has an overshot and a undershot. The overshot water wheel has buckets around its edge. Water is delivered to the top of the wheel. The weight of the water falling into the buckets makes the wheel turn. An overshot water wheel has a very good chance of working with a 80 percent efficiency rate. That means, it may turn as much as 80 percent of the energy of the water into mechanical energy. Though, its use is limited to making small amounts of power. The undershot water wheel is built so the water hits the blades at the bottom of the wheel. The power of the wheel depends on the speed of the water hits the blades. The undershot wheel has such a low efficiency that it is rarely used. Most modern water wheels are horizontal. A horizontal wheel rotates on a vertical shaft. It is driven by the force of the water hitting the blades on one side of the wheel. Horizontal wheels are very efficient if made correctly.
For my experiment I made an vertical undershot waterwheel. For the base of the waterwheel I cut off 8 centimeters of the bottom of a milk jug. Then out of the top of the jug I cut four triangles, four squares and four circles out for the fins of the waterwheel. After that I thumb tacked the 4 triangles to a cork. Put a hole at the end of each side of the cork and glued a skewer in each side for an axis. Then I cut a hole at each side of the base and put the skewers with the cork suspended in the middle. Then I put a 2 inch x 2 inch piece of clay shaped as circles on each side of the skewer. That’s how I got my waterwheel.
In my experiment I didn’t use electricity instead I measured the rate at which a water wheel lifts a weight. Doing this determined the speed at which the water wheel spins. For a weight I used a penny that was taped to a string which was wrapped around the clay.
Electricity is an interesting subject. There is so much you can learn from it, like how our lights turn on or how we make cell phones. This is all a mystery until we finally get a little bit of information in our brains. I've just read two articles, "Energy Story" and "Conducting solutions". I also watched a video called Hands-on Science with Squishy circuits. I learned so much valuable information from these resources.
Compared to the linear peristaltic pump and rotary peristaltic pump, the 360 degree peristaltic pump runs more slowly at the same performance. As a result, the hoses will have longer lifetime which is economic. Furthermore, the 360 degree peristaltic pump produces less friction due to the unique structure, and therefore less thermal. Especially, the 360 degree peristaltic pump has only a single compression per rotation while the ordinary pumps with numerous shoes or rollers have at least two or more compression per revolution. This means that the design of the 360 degree pump will prolong the lifetime of the tube. At the same size, this design will generate more flow volume (55%) at the same
Personal Watercrafts or "jet skis" are basically Personal Watercraft (PWC) are basically small inboard boats able to travel at high speeds due to large amounts of power and very light weight. Alomst all PWC's are under 600 lbs and most of todays PWC's have at least 90 hp.Not only are PWC's some of the fastest water vehicles they are also some of the most maneuverable water vehicles. This is because PWC's propultion is based on a jet that also is it's turning mechanism. When the driver turns the handlebars the jet (via cables) turns in the direction of the handlebars so the stern is pushed in the opposite direction. This allows the driver to turn at a much tighter angle than traditional boats with keels and rudders.The main drawback to this maneuverability is the fact that if there is no thrust coming from the engine the ability to turn is effictively zero meaning that anytime the driver presses the kill switch (a large red button) they lose all ability to steer. This is extremely dangerous whenever an inexperienced person may drive the PWC back to dock or into shore. PWC's have no brakes and have no ablilty to stop other than turning around. They have an extremely efficient ability to hydroplane (when most of the PWC is above water) and it takes most PWC's a few hundred feet to come to a stop after being at full throttle. This is because 600 lbs + a rider is traveling at a very high speed with only minimal friction to slow them down (since PWC's are made to travel with very little friction).
One thunderous afternoon on June 1752, Benjamin Franklin conducted what is known today as the “Kite Experiment”. He wanted to prove that if one object was electrical, the energy from that object could be transferred to another object, therefore being classified as electricity and lightning. With his son William, Ben took a string and attached the kite to it, then he attached an iron key to the kite. Next, they tied a thin metal wire from the key and put the wire inside a Leyden jar which stored all the electrical charge. His experiment profitably showed that his accusations were correct. Many other scientist tried the same experiment and were electrocuted, but Ben Franklin was the lucky one. He changed the world of science.
The spinning wheel is powered by the foot and is very time consuming. The way it worked was the water would turn the water wheel and then it would power the water frame. The water frame could do the work of around 10 people before it was invented. This leads to the problem of the water frame. If there were more water frames, then there were fewer people being able to work and earn money.
Hydro power is one of many examples of alternative energy source. Hydro power is producing energy by moving

Copper wire, bare, 24-gauge, 9 V battery, 9 V battery clip, and more. I am going test each liquid to see which liquid has more electrolytes, and by knowing that it will help me find out which is better for you. I believe by doing this experiment it will help me see if my hypothesis is right or
How can you disturb the balance of charge on objects so they exert electric force? The easiest way is the same way the ancient Greeks did it – by rubbing the 2 objects together. Rubbing neutral objects together allows charged pieces of matter to move from one object to another.
Next, hydro-electricity is electricity produced by moving water, flowing past a turbine connected to a generator (“Hydropower”). According to Nationalgeographic.c...
Electricity was first tested by Benjamin Franklin with his famous kite and lighting experiment (http://www.ushistory.org/franklin/info/kite.htm). Before the kite experiment, he had a lightning rod setup on the top of his house for electrical experimentations. (http://www.ushistory.org/franklin/info/kite.htm). After Franklin, Thomas Edison created light for our homes and businesses, and it was the beginning of great advancements in the electrical industry. Not only did he create the light bulb, but he also invented the microphone, electric pen, telephone receiver, storage battery, and many other inventions before his death. Edison had 1,093 inventions that helped revolutionize of what is today known as electricity (http://www.fi.edu/learn/sci-tech/edison-lightbulb/edison-lightbulb.php?cts=electricity).
Hydropower, the use of water to power machinery or produce electricity, provides the most renewable energy in the United States, and uses alternating current in most modern plants ("Hydropower…”). Hydropower relies on the water cycle and is a clean fuel source; it doesn’t pollute the environment like plants that burn fossil fuels. It is by far the most efficient way to generate electricity, being half the cost of using nuclear power, two-fifths the cost of using fossil fuels, and a quarter the cost of using natural gas ("Wind and Water…”). Also, hydropower is not subject to market fluctuations of embargos, and the average lifespan of a facility is 100 years. Hydropower also has many non-energy benefits such as water supply, flood control, navigation, irrigation, and recreation. However, it does face many environmental challenges such as impacts to aquatic habitats, aesthetic alterations of landscapes, changes to water quality, and interruptions of marine life ("Hydropower…”).
Water Pollution is a current issue that has serious consequences; it progresses everyday in our lakes, oceans, rivers and other bodies of water.

In 1831, using his "induction ring", Faraday made one of his greatest discoveries - electromagnetic induction: the "induction" or generation of electricity in a wire by means of the electromagnetic effect of a current in another wire. The induction ring was the first electric transformer. In a second series of experiments in September he discovered magneto-electric induction: the production of a steady electric current. To do this, Faraday attached two wires through a sliding contact to a copper disc. By rotating the disc between the poles of a horseshoe magnet he obtained a continuous direct current. This was the first generator. From his experiments came devices that led to the modern electric motor, generator and transformer.
