The Energy Journey: Part 3
Be Energy Wise
How to use electricity sensibly
Your Climate Cops mission
• To understand that everyday appliances use electricity
• To understand that different appliances have different power ratings
• To understand how power ratings affect the amount of energy used
• To identify how to save energy by understanding:
- Why do we want to save electricity?
- How will we save electricity?
- How will we know we’ve saved electricity?
Activity 1:
Watt is Right?
How do we measure electricity use?
Did you know…
•
Lots of things in our homes need
electricity to work
•
The amount of electrical power an
appliance uses is measured in
Watts (W) and Kilowatts (kW)
•
1000 watts = 1 kilowatt
Your mission
Are you ready…
Can you put the items in order starting with the one that uses
the least amount of power first?
Climate Cops discussion
So, which appliances do you think need lots of power to make
them work?
How long do you or your family use the different appliances
every day?
For how long do you use the appliances?

Power vs. Energy
•
POWER: we measure the amount of electrical power an
appliance uses in watts (W) or kilowatts (kW)
•
ENERGY: we work out how much electrical energy is used by
multiplying the power of the appliance by the number of hours it
is used for. This gives us the amount of energy used in kilowatthours or kWh
•
One kWh is the energy used when one kilowatt of power is used
for one hour
Saving energy
Climate Cops quick quiz…
•
If an ordinary light bulb uses 40 watts of
power…
How much energy would be used if it was
on for 4 hours?
•
If an energy saving light bulb uses 7 watts
of power…
How much energy would be used if it was
also on for 4 hours?
•
How much energy would be saved?
Activity 2:

Activity 3:
The Earth Needs You
Climate Cops discussion
The most environmentally friendly energy is the energy we don’t
use.
Why do you think it’s important that we try not to waste electricity,
energy and water?
The reasons to SAVE energy
1.
To SAVE the environment
2.
To SAVE the Earth’s non-renewable
sources
3.
To SAVE money
1. To SAVE the environment

Did you know…
When we go about our daily lives, using cars and planes and
heating our homes, all these activities release a gas called carbon
dioxide. Carbon dioxide pollutes our atmosphere.
Carbon dioxide is produced
by power stations that
generate electricity.
Carbon dioxide speeds up
the climate change process.

Negative effects of climate change
•
If the heat cannot escape, the Earth
will warm up too much.
•
This is called global warming or the
greenhouse effect.
Negative effects of climate change
Ice caps will
melt

Droughts
We are already seeing
more droughts in many
countries.

Negative effects of climate change
Flooding
There is heavy rain and
winds causing damage in
others.

2. To SAVE the Earth’s non-renewable
sources
Did you know…
•
Most of the UK’s electricity is
produced by burning fossil
fuels like coal, oil and gas
•
These will eventually run out
3. To SAVE money
Image by: Ajay Singh
Did you know…
Together, we could save
millions of £££’s on our
electricity and gas bills if we
didn’t waste energy.
‘Energy wasting’ cards
Working in groups, see if you can guess all the activities that
waste energy.
Use drama, charades or any other ways you can think of to get
the class to guess the energy wasting activity on your card!
Can you remember all the energy wasting
activities?
•
(Space to write all the correctly guessed activities, plus any
additional suggestions)

So, how could the class be more energy efficient?
Activity 5:
Investigation ‘Light Bulb’
Did you remember that…
•
POWER: measures the
amount of electrical power an
appliance uses in watts (W)
or kilowatts (kW)
•
ENERGY: is the amount of
electrical energy that is used
Climate Cops discussion
Do you think a light bulb uses much power?
Do you think it uses much energy?
Investigation ‘light bulb’
•
Ordinary light bulbs use less power compared to many
other things that use electricity
•
Energy saving light bulbs use even less than ordinary light
bulbs
•
But we have lots of lights in our homes and school
•
We also use lights for long periods of time
Investigation ‘light bulb’ homework
Your mission:
To see how much energy your lights are using in your home.
To see how much energy could be saved if energy saving light
bulbs were used.
Investigation ‘light bulb’ – Follow-up
If all the bulbs in your
house were energy
saving light bulbs, how
much energy would be
saved every day?
Did you know…
•
If everyone fitted just one energy saving light bulb, the
carbon dioxide emissions saved would fill more than 1
million double decker buses
•
If each house fitted three energy saving light bulbs, it would
save enough energy to run the country’s street lights for a
year

Activity 6:
What’s on the Meter?
Quick question…
What is an electricity meter?
Answer…
Every house has an electricity
meter.
It records the amount of
electricity used within our home.
What’s on the meter?
Your mission:
By following the top tips on ‘The Earth Needs You’ poster, can
you reduce the amount of electricity you use?
What’s on the meter?
Homework follow-up
•
When was the most electricity used?
Was it in Week 1 or Week 2?
•
What could be the reasons for this?
•
When do you think the most
electricity is used and why?
- At school
- At home
•
Do you think any energy was
wasted during the week?
•
How could you have been
more energy efficient?
Activity 7:
Be a Climate Cop
Do you want to be a Climate Cop?
The Climate Cops team need your
help to find ways to save energy and
help the planet.
Use your skills of investigation to
help cut down on the energy wasting
activities that could be taking place
in your school.
What did you find in school?

- A suite of posters to remind everyone at
home or at school of the different ways to
be energy efficient
- A leaflet that communicates the top tips on
energy efficiency and the reason’s why it’s
important
- An article for a local community
newsletter that encourages people
to take ‘local action, for global
effect’
