TODAY – starting P3. LO: Describe some different types of renewable energy [C] Know how energy is generated in power stations [B]. STARTER List as many renewable energy sources that you can think of!. Renewable vs Non-Renewable.
List as many renewable energy sources that you can think of!
The turbine drives the generator which creates electricity
The steam turns a turbine
Fuel is burnt to heat water which produces steam
A transformer is two coils of wire on an iron core. It changes electricity into a higher voltage so it can be sent around the national grid at 400000v
When you eat a burger what does your body use the energy for?
Make a list!
efficiency = energy usefully transferred × 100%
total energy supplied
the better as it saves
money and resources
using a diagram
Show how one type of energy can be
converted into other types of energy.
Energy can not be created or destroyed it can only be transformed from one form to another.
Sankey Diagrams show the FLOW of ENERGY
Normal Light Bulb
Energy Saving Light Bulb
Produce an informative leaflet that gives advice on how to make your home more energy efficient
Pick an object from the kitchen and draw an energy flow diagram for that item. Then explain which is the wasted and which is the useful energy output.
Energy Transferred (J)
Number of kWh
Cost per kWh
Energy Usefully Transferred
Total Energy Supplied
Produce a revision guide page that include the ‘Electrical Energy’ equations.
D – include information on power, electricity and energy
C – include all 4 formula triangles
B – create your own worked examples for each formula triangle
Extension – write some quiz questions on this topic
Power is 600W and the Voltage is 30V what is the current?
You use 40kWh of electricity at a cost of 2 p per kWh, what is the cost?
Work out the power. 600kWh of energy is transferred in 3 hours.
400 J of energy is transferred at a power of 80 W. How long does this take?
Control rods control the speed of the nuclear reaction
(Uranium fuel rods)
What is ionising radiation and why is it dangerous?
photon of ionizing radiation
positively charged atom
Ionization happens when a photon with enough energy hits an atom or molecule inside a material.
How a Generator Works
You can make electricity by moving a magnet in or near a coil of wire.
This diagram is one of a small dynamo to power a bicycle light but works on the same principle as large power station generators.
