Making a model wind turbine
What size is your carbon footprint?
We’re going to give you some
ideas about how to make a wind turbine.
It will generate electricity from ‘wind’
made by a fan!
You could try
using it outside in
the real wind.
Or I could blow on
it!

What size is your carbon footprint?
We made the tower for
the wind turbine out of a large plastic
bottle. The bottle is partly filled with
gravel. Can you think why?
A piece of thick
cardboard has been taped on top to
make a platform for the turbine head (or
rotor) to sit on. I made sure the front
edge sticks out further than the
bottle so the blades can turn.

Now we can
tape the electric
motor to the front of
the tower. Make sure
it sticks out over the
front of the card,
won’t you?
But where are
the blades?

What size is your carbon footprint?
The electric motor
is going to be the generator.
It will produce a small amount
of electricity. Look at what
to do next to make
the blades!
You use corrugated
plastic to make the blades,
dowel to join the blades to the
wooden hub and a black pulley
wheel – and that makes
a turbine. Brilliant!

Not bad
Superhero,
for our first
attempt!
Cool.
Now what
happens?

The turbine is just about
ready to test. I’ve had to make a few
adjustments but it’s fine now.
Can you see how the crocodile clips fix
on the back of the electric
motor?
That looks
great!

Do you know what
this is, Superhero?
Ooh, is it a TV
controller? Let’s
watch cartoons!
No, it’s a
digital voltmeter,
for measuring
electrical output.

We’re ready to test our
turbine in front of the fan. After
that, we can try changing the shapes of
our blades and tilting them different
ways to get the best reading
on the voltmeter.
What fun!
Can I have a go?
Please, please….

All these different turbine
blade shapes were made at school.
Which do you think produced the
most electricity? Why?
Try bending the blades
lengthways slightly and see
what happens.

Why not
cover the plastic bottle with
paper and decorate it? You could
make it look like a real wind
turbine tower or like a more
colourful version!
Can you think of a
slogan to go with your wind turbine?
Like ‘Winderful, Wonderful Wind
Power’!
