During Science Week we explored electricity and found out about how it is generated.
This is one of the websites we thought was very useful:
Have another look, and see if you can write a paragraph explaining how electricity is made.
You could have a go at describing different methods if that's too easy!
How about hydro-electric power? Or nuclear energy?
Please have your blog entries written by Wednesday 19th November!

How Electricity is made:
ReplyDeleteIn the early 1800s, Michael Faraday discovered "electromagnetic induction", which means if he put a magnet through a loop of wire, it would create electricity.
In 1882, Thomas Edison opened the first full-scale power-plant in New-York City. Edison's electric generator was a bigger version of Faraday's basic experiment: A big magnet rotates around a wire to produce an electricity

^_^ < Ooo! If we do this, it will produce Electricity! Lets get to work! :P >
:D:D:D:D:D:D YAY! Electricity! :DD
Coal is dug up and sent to the boats and trains to deliver.
Then, the coal is burnt and it turns into water and then the water turns into steam...
Inside the generator, the steam spins in the turbines.
The spinning turbine rotates a big magnet around a piece of wire & then that motion creates a magnetic field that electrifies the wire.
The electric current flows through the wire and is pushed out through high-voltage transformers.
In order to understand electricity, we need to know something about atoms. Everything in the universe is made of atoms — every star, every tree, every animal. The human body is made of atoms. Air and water are, too. Atoms are the building blocks of the universe. Atoms are so small that millions of them would fit on the head of a pin. Now that, it what I am shocked by.
A battery produces electricity using two different metals in a chemical solution. A chemical reaction between the metals and the chemicals frees more electrons in one metal than in the other. One end of the battery is attached to one of the metals and then the other end is attached to the other metal.
The end that frees more electrons A battery produces electricity using two different metals in a chemical solution. A chemical reaction between the metals and the chemicals frees more electrons in one metal than in the other. One end of the battery is attached to one of the metals; the other end is attached to the other metal.
The end that frees more electrons develops a positive charge and the other end develops a negative charge. If a wire is attached from one end of the battery to the other, electrons flow through the wire to balance the electrical charge.
A positive charge and the other end develops a negative charge. If a wire is attached from one end of the battery to the other, electrons flow through the wire to balance the electrical charge.
first the wind turbines go into the underground cable into the substation threw wire into the pylon into the transformer into our houses.
ReplyDeleteThere are lots of ways to generate electricity but my favorite is nuclear energy. Nuclear power stations use uranium , which is radioactive for fuel. The atoms in uranium release neutrons , neutrons split the atoms creating heat , radiation and more atoms repeatedly heating the water making steam. Steam turns the turbines causing them to spin and power the generator .
ReplyDeleteWe had a experiment with Mr Farnell. At that experiment the equipment we needed was one wire with two crocodile clips attached to each end of the wire,one battery and one light bulb.
ReplyDeleteFirst we get the battery,then we get the crocodile clips attached to each end of the wire. Then we stick the one side of the crocodile clip to the negative end of the battery and stick the other crocodile clip to the light bulb, we cold see beause of negative end of battery was used, the light bulb did not generate the light, so then we tried the positive end of the battery and the light bulb shined.
Mrs Messa I know only two of people who made electricity , there's Michael Faraday and Benjamin Franklin . I have loads of ways to generate electricity , there's a wind turbines , sea turbines , nuclear power , solar power , biomass fuel and hidro power plants .
ReplyDeleteHow to generate electricity
ReplyDeleteHydro electric power stations include a big wheel, which is connected to the generator. Water runs rapidly next to the wheel, making the wheel move faster therefore creating electricity.
Urainium is a radioactive fuel used in nucular power stations. Neutrons are small particles released by uranium atoms. Neutrons are small particles released by uranium atoms. Neutrons hit other uranium atoms and p which makes heat, radiation and more neutrons. The heat produces steam, generating electricity.
ReplyDeleteThere are different ways to make electricity
ReplyDeleteIn a nuclear power station they use uranium to generate electricity. Firstly they send it to the generator.Then they send it to a transformer. The transformer stores all the energy. After that they send it to a pylon. Finally they send it to our houses and we can use the energy.
In a biomass power station they use biomass fuel to generate electricity.Firstly they send the electricity to a generator Then they send it to a transformer. The transformer stores the energy. After that they send it to the pylon. Finally they send it to our houses and we can use the electricity.
Hydro electric power
Hydro electric power is powered by water. It has the advantage of only using renewable resources.
The main advantage of hydro electric power are that it is clean and renewable.It is clean because it won't produce any harmful gases like carbon dioxide.It is renewable because the water is not deplted.
Nuclear energy
Nuclear energy orgnites from the splitting of uranium atoms in process is called fission.Use turbines to generate electricity.
The advantages for nuclear powers do not produce carbon dioxide.
The disadvantages for nuclear powers are that they are non-renewable energy resources.They will produce hazardous for thousands of years.They must be stored carefully. There are hazardous because they could cause
an explosion which release highly radio active materials into the environments.
How Electricity is generated
ReplyDeleteIn a nuclear power station uranium is used to make electricity. Uranium is a very dangerous radioactive fuel. If you what to make electricity at home you can roll a magnet on a coil of wire and that makes electricity. In a power station heat boils the water and that produces steam. The steam turns the turbines and makes electricity in the generator. A wire goes from the generator to a transformer and some more wires go from the transformer to a pylon. There are some more wires which go from the pylon to a post that has a transformer on. There are wires that go from the post to our houses. There are lots of other ways to make electricity but there are only 3 ways here.
Electricity can be generated in many ways; For example, a hydro -power- plant uses water to turn a big turbine. The water can be recycled easily and isn't radioactive. When the water is turning the turbine it makes electricity.
ReplyDeleteElectricity can be generated in many ways, for example: in coal, oil or gas-fired power stations; we can burn fuel into steam. In a hydro electric power station, the water is dropped through a big wheel making it turn. This is connected to the generator. In Nuclear power stations, they use radioactive fuel called "Uranium". Uranium atoms release small particles called "neutrons", which hit other uranium atoms which split them creating heat and radiation. In a biomass power station, they use fuel made out of shrubs and animal poo. It is burnt in a boiler to produce high pressure steam. "Geothermal energy" uses steam from hot water reservoirs beneath the earth. Engineers drill down to the reservoirs. As the water rises to the surface it begins to boil.
ReplyDeleteHere is the main idea about how electricity is produced. In most power stations, you have to heat water, then it will turn into steam. This is called evaporation.
Later on, the steam floats into small tubes. After that, it is sent into a small machine named: steam turbine. The steam forces the blades to move. Then it goes into a mini-generator.
A magnet is put between three coiled wires. Then the two balls at the end of the magnet reacts to the wires and makes electricity the quickest way possible. Five minutes later, the electricity is sent to a medium-sized engine called a transformer. This lets the electricity travel to every pylon in the entire world.
Electricity can be generated by spinning a magnet around a coil of wire. This produces an electric current (we cannot see it).
ReplyDeleteAnother way of making electricity (in a hydro-electric power station) is water dropping onto a turbine. The water forces the turbine to spin, that electricity is sent to our houses by a few wires.
A completely different way of making electricity (at a gas, fire, or oil station). People dig up animal poo, mud and it gets burned which forces the turbine to move. (If the turbines overflow with steam some of it will drop down to a place called a cooling station where it is cooled and it can also possibly be reused again. The turbines pass the steam onto the generator which starts to move. The generator passes the electricity to a transformer which then passes all the electricity to a pylon which delivers it to our houses. Pylons are usually found on a motorway. The pylons then store the electricity and pass it to our houses, ready to use.
This is not a way of making electricity but seeing it. It is thought that Benjamin Franklin had thought lightning and thunder were so powerful they were signs of electricity.
An easy way of making electricity is to burn coal , the steam forces the turbines to move. The stream gets passed onto the generator and then to the transformer. Then the electricity gets passed onto a pylon. The pylon passes electricity to our house and can then be used.
