1.Where is electricity generated? 2.How are fossil fuels created? 3.What type of energy is stored in a fossil fuel? 4.What is the purpose of the fossil fuel in a power station? 5.Explain how the generator is turned in a fossil fuel fired power station
To understand how the National Grid is used to transport electricity around the country State how electricity is transported around the country State the different parts of the National Grid and explain their functions Analyse the pros and cons of transporting electricity through the National Grid
Discussion How does electricity made at a power station reach Langley Mill? Does the electricity have to be changed in some way as it is sent?
Set up in 1926, the National Grid is a network of power stations and cabling that carries electricity around the country Electricity is generated at power stations and distributed around the UK through a vast circuit of electrical cabling
Step-Up Transformer Step-Down Transformer This is how our National Grid Works!! Increases the voltage so current can be lower. Why? Decreases the voltage so current can be higher. Why?
Cut out and recreate the national grid in the form of a poster. Follow the instructions on the sheet. You can make it as complicated or as simple as you like. Keep bits of paper on desk, or take to the bin.
1.Cut out the pictures 2.Arrange them into a diagram of the National Grid 3.Draw cables 4.Label what is happening at each stage
Beat the teacher- A step-up transformer reduces the voltage through the transmission cables, which increase the current. This will make the transfer of electricity more efficient as less energy is lost as light. Step-low transformers are essential as they reduces the currant to a safe working value for consumers. Can you find 7 mistakes and beat the teacher? To know how electricity is generated and transferred to our homes.
