Task 1 - Starter




Hands up!





I know the answer!




Discuss in pairs or threes:



Imagine your teacher tells you to go out and buy some energy, and gives you a £20 note.







What would you come back with?  Write your best 3 ideas on the mini-whiteboards.



Your teacher will ask you to share your ideas with the class, and may write some of your ideas on the board.











Task 2 - Ten types of energy





I know all eleventy-two types of energy.






There are ten types of energy that you need to know about.




Your teacher will show you some of these, using a range of toys and machines.




Your teacher may write some of your ideas, suggestions, and comments on the board.











Simple animations



These animations show examples of some types of energy and some simple energy transfers.





Right click on the animation below, and click "play".



Flash technology!










The ten types of energy





Remember ALL the things!








You might want to write the ten types of energy in your exercise book.







  Can be stored




  Cannot be stored



  ▪ chemical energy


  ▪ elastic potential (strain) energy


  ▪ gravitational energy


  ▪ nuclear energy


  ▪ magnetic energy





  ▪ heat (thermal) energy


  ▪ light energy


  ▪ sound energy


  ▪ kinetic (movement) energy


  ▪ electrical energy














Task 3 - Energy Circus




Honk honk!







Is this REALLY the noise dinosaurs made...?!
















Your teacher has placed a range of devices around the room, which may include some of the examples below.





▪ desk lamp


▪ candle


▪ electric heater


▪ airzooka


▪ desk fan



▪ squeaky horn


▪ animal "groan tube"


▪ glow stick


▪ wind-up toy


▪ toy car at the top of a ramp





Visit each station in order.  All of these devices use and produce energy.  Which types of energy can you identify?  Record your results in this table.





There is a blank copy of the table here, if you wish to choose your own set of devices.











Task 4 - Energy transfer diagrams





Think hard!




Think about which forms of energy are used by each device, and which forms of energy are produced.




We can show the energy changes using an energy transfer diagram, like the one below:








Example - Energy changes in a television
















Now you draw some...



Think hard!




Draw energy transfer diagrams for five devices from your table.



▪ Write the name of the device by each diagram, and underline it.


▪ Draw the arrows using a pencil and ruler.


▪ Label the types of energy used, and the types of energy produced.








1. Which types of energy are useful, and which are wasted?  Label them on your energy transfer diagrams.

2. Find out what efficient means.  How is this related to the amounts of useful and wasted energy?


















The television.







Draw energy transfer diagrams for the following devices:




▪ A television set


▪ A washing machine


▪ A petrol powered car, driving at night


▪ A hairdryer


▪ A wind turbine




Label each type of output energy as either useful or wasted.
