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.
|

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

Remember ALL the things!
|
|
You might want to write the ten types of
energy in your exercise book.
|
|
|
|
|
|
|
▪ chemical energy
▪ elastic potential (strain) energy
▪ gravitational energy
▪ nuclear energy
▪ magnetic energy
|
|
▪ heat (thermal) energy
▪ light energy
▪ sound energy
▪ kinetic (movement) energy
▪ electrical energy |
|
|
|

|
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
|
|
|
|
|
|
|
|
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.
|
|
|
|
|
|
Extension:
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.
