Right, girls and boys, what actually is this?
STUDENTS: It's a solar panel. A solar panel.
Well, it's actually a solar cell.
Does anyone know how a solar cell actually works?
I think, like, it sits on the top of a roof or some part of...
..like to get electricity.
Like, the sun hits it and it stores electricity
so then you can use it in household appliances.
OK, so the energy that the solar cell's using is what?
-Er, sunlight? -TEACHER: Sunlight.
Is that a renewable energy or a non-renewable energy?
STUDENTS: Renewable.
So it's obviously very, very good for our environment, isn't it?
So we have to work out how this is going to convert light energy into...
What sort of energy will it produce?
Um, solar energy, isn't it?
TEACHER: What's it going to create through the wires?
-What can we create with this? -STUDENTS: Electricity.
Fantastic. Electricity.
So I'm wondering whether one of you can come and show
how we can make this circuit actually work.
Now, while he's doing that,
what angle do you think that solar cell would need to be in?
Well, it'd need to be an angle so the sun can hit it, so like that.
Excellent. So...that's it.
-I have a light. -Alright. OK, show the group.
We have success. It has produced what sort of energy?
-STUDENTS: Solar. Electricity. -TEACHER: Electricity.
Let's check the efficiency of the gas heater.
-So...so... -So the gas...
-So the energy... -..energy rating is...
-4 stars. -4.5.
4.5.
And the indoor gas heat emission rating is...
-BOTH: Six stars. -That's pretty good.
TEACHER: Which is really good.
Now, we've just had a look around the school
at some energy efficient type things that we have around the school.
What types of things have we got in our school
that's actually working really well?
-These lights. -TEACHER: OK.
So how have they improved
since the old lights we used to have, with the fluoro tubes?
Well, the old lights had really big, like, bulbs,
and they used a lot of power,
and these ones are more energy efficient.
-They've got fluoro in them. -TEACHER: Fantastic. And what else?
What happens to our lights after a certain period of time?
-BOY: Well, the lights turn off. -TEACHER: OK.
So after a period of time,
the lights will turn off quite naturally to conserve energy.
I thought it might be a really good idea if we actually made some prompts
for some of the classroom teachers at Coolbinia
to actually be a little bit more efficient with our lighting.
So what could we do?
Or what could we tell our classroom teachers as they exit a classroom?
GIRL: Have a little catchphrase kind of thing.
-Catchy phrase to turn them? STUDENT: Off.
Off. Fantastic.
Alright, so what I want you to do
is actually have a think about a catchy little phrase
that would remind classroom teachers
to actually turn their light switches off as they exit a room.
So have a think and grab your textas and see if you can design
a really good little prompt with a catchy phrase.
And you need a picture as well. OK? Off you go.
"Be brave and save". But how? What do they need to do?
You need to be really clear with your little phrase.
What action do you want the person to do?
-Turn the lights off. -OK.
So how can you put that into a nice catchy phrase?
(STUDENT HUMS)
STUDENT: Find words that rhyme with it and stuff?
TEACHER: Fantastic. So can you think of a good one?
STUDENT: Not yet. (LAUGHS) Um...
TEACHER: Who's thought of a good catchy phrase?
(LAUGHS) It's kind of in the song 'Wake Me Up Before You Go'.
It goes "Turn me off before you go 'cause I won't turn off by myself."
TEACHER: Great. Fantastic.
We were wondering if you could maybe put this up next to your light switch
so that you remember to turn off your lights
before you go out of the classroom,
so we can save more energy in our school.
I'd love to. Thank you. Great.
