THE SQ PARTY - SUPPORTING YOUR RIGHT TO LIVE AS YOU WANT

We don’t need to give this

all up?

There is a lot of nonsense spoken about climate change. Oil is the most convenient

fuel we have.

Trust us, we’re not interested in money and

power.

You can’t compete with us. Little girls don’t

control the press and TV like we do. What will you do start a Facebook group

or do some tweets?

Engage 4

Elicit 7

No that’s me. I’m called Gaia.

I brought you here to 2010 to save the planet from Felix and his propaganda.

Oh I can hear voices again…

Elicit 8

Energy for the Earth comes from many sources – and some of them are badly managed and causing me problems.

First task: The SQ party rubbished Sun and wind power. Felix can’t be right? We need evidence … and we’re losing the media war.

Let the class decide …

We need a PRACTICAL INVESTIGATION

Explore 11

Our questions for the class are …

SQ Party: there is very little energy in Sun or wind. Its not a concentrated source like oil. When the sun goes down your TV will stop. Ha Ha!

How much ELECTRICAL energy can you get from solar power or from wind power ?

Will it work a motor or a light?

Does it still work when the wind drops or daylight is poor?

… or is the SQ Party right?

SUN

Investigate the voltage output using a multimeter.

What happens in dim light?12

Use a wind generator or small dynamo that would be in a wind generator.

What happenswhen the wind drops?

or SQ?

I’m worried by those nosey kids. Drat!

They’ve found out about alternative energy sources. I’ll have to increase the media pressure.
