...simple energy transfers...










Woop Woop!



• Be able to name the ten types of energy.



• Know that energy can be changed from one form to another.



• Be able to give examples of energy transfers, and represent these as diagrams.










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 2a - Ten types of energy




Strain energy.




Sound energy.




Lots of types of energy!




I know all eleventy-two types of energy.





There are ten types of energy that you need to know about.  Some types of energy can be stored, but others cannot.




Stick this table into your exercise books.

Your teacher will show you demonstrations and examples of each type of energy - using a range of toys, machines and devices.




Teacher note: list of suggested devices and demonstrations coming soon.











Task 2b - Energy skate park simulation




Another fantastic PhET simulation!



Works on tablets and mobiles!




Simple energy animations (below) require Adobe Flash Player.

(PC only, no support for tablets and mobiles)



The energy skate park simulation can help you explore ideas about gravitational energy, kinetic energy, heat energy, friction and more.



Applet credit: PhET.  Click below to run the simulation in full screen mode.





You may also want to look at these simple animations.

Right click on the animation, and click play.

Teacher note: these basic animations are ok as visual cues, if you don't have access to a range of toys and devices for demonstrations.  They require Adobe Flash Player to run (PC only, no support for tablets or mobile devices).









Task 3 - Energy Circus




Honk honk!







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



Strain energy.
















Your teacher has placed a range of devices around the room.  All of these devices use and produce energy.





1) desk lamp


2) candle


3) electric heater


4) airzooka


5) desk fan



6) squeaky horn or hand bell


7) animal "groan tube"


8) glow stick


9) wind-up toy


10) toy car at the top of a ramp



Visit each station in order.  Which types of energy can you identify?  Record your results in the table below.

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.



Write 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:



1) A television set


2) A washing machine


3) A petrol powered car, driving at night


4) A hairdryer


5) A wind turbine



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