Transcript of Clayton H.
1. Fossil fuels,coal,and natural gas can be used to make electricity.Steam and nuclear power are also used.Biomass,wind energy,geothermal energy,and solar energy are used too.
2. Hydroelectric power plants use the energy of falling water. They use it to spin generator turbines and create electricity.Alot of people use the electricity.
3. Nuclear power plants rely on uranium.Uranium is a type of mineral that is specially processed.Heat is then released from splitting uranium atoms and is then used to convert water to steam.Steam turns the turbines.
4. Natural gas is often found with oil,it is also a fossil fuel.Some power plants burn natural gas instead of coal. When this happens it makes a lot of steam.
5. They are all found deep in the earth. They are all burned to create steam,which creates steam.
6. When we burn fossil fuels we create air pollution.It releases carbon dioxide.Carbon dioxide is a gas that causes the greenhouse effect.
1.Electricity is a type of energy that can build up in one place or go to another.
When electricity grows in one place to another.When electricity grows in place it is known as static electricity. Electricity that moves is known as current electricity.
2. Electricity starts out at the power plant and made from coal,natural gas,and water or wind power. Once electricity is created ,it is sent to a transformer, which increases the amount of voltage so that it can be sent long distances. They do this so that it can be sent long distances althrough out the country.
3. Electricity is generated by coal which is dug up and sent to trains and boats. The steam makes a big fan called a turbine. The rotating turbine rotates a huge magnet around a piece of wire and that movement creates a magnetic field that electrafies the wire. Then the electric current flows through the wire and is pushed out through high voltage transformers.
4. A conductor is a substance that allows electricity to pass through it. When electrical current occurs it is called conduction.In a conductor energy flow freely, but in a insulator it cannot.
5.Insulators can stop the free flow of energy. They stop the flow of energy because energy cannot flow through them. Like wood is an insulator because it doesn't let energy flow through ,but metal is a great conductor because it allows energy to flow through it.
600 BCE : in Greece a mathmation named Thales discovered that amber rubbed with animal fur attracted light objects. 300 BCE: a chinese general named Huang-ti was supposed to be the first to use a lodestone compass. 1660: a german experimenter named Otto Van Guericke built the first electric generating machine, he also showed that electricity could be transmitted by using a wet string to conduct electricity several feet. Early 1700's : Several Englishman published works trade scribed interesting experiments with electricity. Francis Hauksbee ,removed air from a glass globe. This made the globe rotate while rubbing with wool cloth. The globe gave off so much light that she could read large letters in a dark room. when the globe gets hotter it attracts lighter objects from a great amount of distance. Another experimenter named ,Stephen Gray, discovered conductivity.Gray, found that an electric could transmit electricity through another persons body. He found that even water could be electrified. Charles Du Fay, in Paris preformed many experiments based on Gray's work. He came across a thought that everything and everyone contained electricity. Which we know is true. The only thing he did not have was lightning ! 1800's : Everyone was fascinated by electricity. Pieter Van Musschenbroek invented a Leyden Jar. This was a storage jar that showed electricity could be stored for future use. Charles de Coulomb was interested in measuring the amount of electricity and magnetism generated in a circuit. A coulomb is still what we call the unit of electrical charge today. 1879: Thomas Edison is the best known for his invention of the lightbulbs. It is a dream to bring light into every single home and factory. the end
1. Tightening muscles, making it almost impossible to pull away. Constricting lungs, that makes it harder to breath. The heart is interrupted and your blood vessels tighter. It burns where electricity enters and exits.
2. Don't touch the ground and a power line at the same time. Trees can fall on power lines and if you touch the tree you could get shocked. Never put a sheet or a rug over a power line.
3. One example of a safety device is a circuit. Another example is a smoke alarm. And another is a security camera.
4. Circuits -a place were you plug stuff in.
lightbulb -something that has light on it.
