Hi, Julia.
0:01
S…
Speaker 1 (dictation-t1-science)
Hi,
0:02
S…
Speaker 1 (dictation-t1-science)
Bob.
0:02
S…
Speaker 2 (dictation-t1-science)
Thought about the science project yet?
0:05
S…
Speaker 3 (dictation-t1-science)
Which one?
0:06
S…
Speaker 3 (dictation-t1-science)
The presentations are scheduled for next month.
0:09
S…
Speaker 2 (dictation-t1-science)
The experiments that you and I are working on to demonstrate density,
0:13
S…
Speaker 2 (dictation-t1-science)
buoyancy and the compression of gases.
0:15
S…
Speaker 3 (dictation-t1-science)
That'll be complicated.
0:17
S…
Speaker 3 (dictation-t1-science)
Well,
0:18
S…
Speaker 2 (dictation-t1-science)
it's not supposed to be.
0:19
S…
Speaker 2 (dictation-t1-science)
It'll be part of the Making Science Simple series that's being showcased
0:23
S…
Speaker 2 (dictation-t1-science)
next year.
0:23
S…
Speaker 2 (dictation-t1-science)
And we have to be ready to demonstrate by the end of next week.
0:27
S…
Speaker 1 (dictation-t1-science)
Oh,
0:28
S…
Speaker 1 (dictation-t1-science)
well.
0:29
S…
Speaker 1 (dictation-t1-science)
Simple,
0:30
S…
Speaker 3 (dictation-t1-science)
you say?
0:31
S…
Speaker 1 (dictation-t1-science)
Yes,
0:32
S…
Speaker 2 (dictation-t1-science)
not just the concept,
0:33
S…
Speaker 2 (dictation-t1-science)
but the materials too.
0:34
S…
Speaker 1 (dictation-t1-science)
We have to use cheap,
0:36
S…
Speaker 2 (dictation-t1-science)
readily available common items.
0:38
S…
Speaker 2 (dictation-t1-science)
Expensive lab equipment is out of the question.
0:41
S…
Speaker 3 (dictation-t1-science)
I remember something about using recycled or throwaway
0:45
S…
Speaker 3 (dictation-t1-science)
items if possible.
0:46
S…
Speaker 3 (dictation-t1-science)
Anything portable that we can bring into the lab.
0:49
S…
Speaker 2 (dictation-t1-science)
That's right.
0:50
S…
Speaker 3 (dictation-t1-science)
Well,
0:51
S…
Speaker 3 (dictation-t1-science)
any ideas for the project?
0:53
S…
Speaker 2 (dictation-t1-science)
What about the classic Cartesian diver?
0:56
S…
Speaker 3 (dictation-t1-science)
Is that the same as a Cartesian devil?
0:59
S…
Speaker 3 (dictation-t1-science)
The invention named after the famous French physicist René Descartes?
1:04
S…
Speaker 1 (dictation-t1-science)
Yes.
1:05
S…
Speaker 2 (dictation-t1-science)
A long time ago,
1:06
S…
Speaker 2 (dictation-t1-science)
superstitious people labelled it that because they couldn't comprehend the
1:10
S…
Speaker 2 (dictation-t1-science)
scientific principles it demonstrated.
1:12
S…
Speaker 2 (dictation-t1-science)
They thought it was black magic.
1:14
S…
Speaker 3 (dictation-t1-science)
How shall we do it?
1:16
S…
Speaker 2 (dictation-t1-science)
By keeping it as simple,
1:18
S…
Speaker 2 (dictation-t1-science)
transparent and economical as possible.
1:21
S…
Speaker 3 (dictation-t1-science)
So,
1:21
S…
Speaker 3 (dictation-t1-science)
to start with...
1:23
S…
Speaker 2 (dictation-t1-science)
Open your pencil case and let's have a look.
1:26
S…
Speaker 2 (dictation-t1-science)
Hmm, you haven't got any...
1:28
S…
Speaker 3 (dictation-t1-science)
Any what?
1:29
S…
Speaker 1 (dictation-t1-science)
Paperclips.
1:30
S…
Speaker 3 (dictation-t1-science)
Oh, there are lots of them in the bottom of my bag.
1:33
S…
Speaker 3 (dictation-t1-science)
They slip off my papers and collect in the bottom.
1:36
S…
Speaker 3 (dictation-t1-science)
Look,
1:37
S…
Speaker 3 (dictation-t1-science)
here's half a dozen.
1:38
S…
Speaker 2 (dictation-t1-science)
But they're all big metal ones.
1:40
S…
Speaker 2 (dictation-t1-science)
I want little ones.
1:41
S…
Speaker 1 (dictation-t1-science)
Small,
1:42
S…
Speaker 2 (dictation-t1-science)
vinyl -covered,
1:43
S…
Speaker 2 (dictation-t1-science)
multicoloured ones.
1:44
S…
Speaker 3 (dictation-t1-science)
Oh,
1:45
S…
Speaker 3 (dictation-t1-science)
I've got one or two of them,
1:47
S…
Speaker 1 (dictation-t1-science)
too.
1:47
S…
Speaker 1 (dictation-t1-science)
Great,
1:48
S…
Speaker 2 (dictation-t1-science)
and...
1:49
S…
Speaker 1 (dictation-t1-science)
If we look around,
1:50
S…
Speaker 2 (dictation-t1-science)
especially on the floor,
1:52
S…
Speaker 2 (dictation-t1-science)
we're bound to find a few more.
1:54
S…
Speaker 1 (dictation-t1-science)
See?
1:54
S…
Speaker 1 (dictation-t1-science)
Here.
1:55
S…
Speaker 3 (dictation-t1-science)
What else do we need?
1:56
S…
Speaker 2 (dictation-t1-science)
A small rubber band.
1:58
S…
Speaker 3 (dictation-t1-science)
Well,
1:59
S…
Speaker 3 (dictation-t1-science)
I've got one of those in my pocket.
2:01
S…
Speaker 1 (dictation-t1-science)
No,
2:01
S…
Speaker 2 (dictation-t1-science)
not that kind.
2:02
S…
Speaker 2 (dictation-t1-science)
Let's go and ask Tara.
2:04
S…
Speaker 1 (dictation-t1-science)
Why?
2:05
S…
Speaker 2 (dictation-t1-science)
Those really small coloured bands for making ponytails are ideal.
2:09
S…
Speaker 1 (dictation-t1-science)
Hey,
2:09
S…
Speaker 1 (dictation-t1-science)
Tara?
2:10
S…
Speaker 1 (dictation-t1-science)
Yes?
2:11
S…
Speaker 2 (dictation-t1-science)
Have you got any spare rubber bands,
2:14
S…
Speaker 2 (dictation-t1-science)
like the ones you fasten your hair with?
2:15
S…
Speaker 1 (dictation-t1-science)
Oh,
2:17
S…
Speaker 1 (dictation-t1-science)
heaps.
2:17
S…
Speaker 1 (dictation-t1-science)
A whole packet full.
2:18
S…
Speaker 1 (dictation-t1-science)
Help yourselves.
2:19
S…
Speaker 3 (dictation-t1-science)
Terrific.
2:21
S…
Speaker 3 (dictation-t1-science)
So far it hasn't cost us anything.
2:23
S…
Speaker 3 (dictation-t1-science)
What now?
2:24
S…
Speaker 2 (dictation-t1-science)
Let's go and rummage through the recycling bins beside Joe's
2:29
S…
Speaker 2 (dictation-t1-science)
Mini Markets.
2:29
S…
Speaker 3 (dictation-t1-science)
What for?
2:30
S…
Speaker 2 (dictation-t1-science)
We want a two -litre plastic soft drink bottle with lids.
2:34
S…
Speaker 1 (dictation-t1-science)
Hey,
2:35
S…
Speaker 3 (dictation-t1-science)
I draw the line at sorting through other people's rubbish,
2:38
S…
Speaker 3 (dictation-t1-science)
and we're also not likely to find one with a lid.
2:41
S…
Speaker 1 (dictation-t1-science)
Well,
2:42
S…
Speaker 2 (dictation-t1-science)
go into the store and buy two litres of soft drink.
2:45
S…
Speaker 3 (dictation-t1-science)
What flavour?
2:47
S…
Speaker 2 (dictation-t1-science)
It doesn't matter what kind of drink you get.
2:49
S…
Speaker 2 (dictation-t1-science)
Just make sure it comes in a clear PET bottle.
2:52
S…
Speaker 3 (dictation-t1-science)
Where are you going?
2:54
S…
Speaker 2 (dictation-t1-science)
To the cafeteria behind the resource centre.
2:56
S…
Speaker 1 (dictation-t1-science)
What for?
2:57
S…
Speaker 2 (dictation-t1-science)
I'm after some straws.
2:59
S…
Speaker 3 (dictation-t1-science)
I can get them from the shop when I buy the drink.
3:02
S…
Speaker 2 (dictation-t1-science)
No, I've seen theirs.
3:03
S…
Speaker 2 (dictation-t1-science)
They're the waxed paper ones.
3:05
S…
Speaker 1 (dictation-t1-science)
We need clear plastic,
3:07
S…
Speaker 2 (dictation-t1-science)
and I know they've got them in the cafeteria.
3:09
S…
Speaker 2 (dictation-t1-science)
I'll also see if I can get a tall plastic cup from there.
3:12
S…
Speaker 1 (dictation-t1-science)
Good luck.
3:13
S…
Speaker 3 (dictation-t1-science)
Meet you back here in five minutes.
3:16
S…
Speaker 2 (dictation-t1-science)
Maybe longer because I want to go over to my locker and get a wire coat hanger.
3:20
S…
Speaker 1 (dictation-t1-science)
Right.
3:22
S…
Speaker 3 (dictation-t1-science)
Have we got everything now?
3:24
S…
Speaker 2 (dictation-t1-science)
I think so.
3:25
S…
Speaker 2 (dictation-t1-science)
I've got extras of most things,
3:28
S…
Speaker 2 (dictation-t1-science)
so don't worry if this doesn't work first time.
3:31
S…
Speaker 3 (dictation-t1-science)
OK.
3:32
S…
Speaker 3 (dictation-t1-science)
Assembly.
3:33
S…
Speaker 3 (dictation-t1-science)
Step one.
3:35
S…
Speaker 2 (dictation-t1-science)
Take a straw and fold it in two.
3:38
S…
Speaker 4 (dictation-t1-science)
No,
3:39
S…
Speaker 2 (dictation-t1-science)
not like that.
3:40
S…
Speaker 2 (dictation-t1-science)
These plastic ones are quite hard to fold.
3:43
S…
Speaker 2 (dictation-t1-science)
Try pinching it in the middle.
3:45
S…
Speaker 2 (dictation-t1-science)
That should make it easier to bend.
3:47
S…
Speaker 2 (dictation-t1-science)
You may even have to bite it,
3:49
S…
Speaker 2 (dictation-t1-science)
but not too hard.
3:50
S…
Speaker 2 (dictation-t1-science)
You want a sharp crease,
3:52
S…
Speaker 2 (dictation-t1-science)
but you don't want to break it.
3:54
S…
Speaker 3 (dictation-t1-science)
How's this?
3:55
S…
Speaker 1 (dictation-t1-science)
Good.
3:57
S…
Speaker 2 (dictation-t1-science)
Now,
3:57
S…
Speaker 2 (dictation-t1-science)
second step.
3:58
S…
Speaker 2 (dictation-t1-science)
Wrap a rubber band several times around the ends to hold
4:03
S…
Speaker 2 (dictation-t1-science)
them together.
4:03
S…
Speaker 1 (dictation-t1-science)
Then...
4:05
S…
Speaker 2 (dictation-t1-science)
Add weight to the diver.
4:06
S…
Speaker 3 (dictation-t1-science)
So,
4:07
S…
Speaker 3 (dictation-t1-science)
this straw is the diver?
4:09
S…
Speaker 1 (dictation-t1-science)
Yes.
4:09
S…
Speaker 2 (dictation-t1-science)
See how I'm pulling the outside end of a paperclip out a bit?
4:13
S…
Speaker 4 (dictation-t1-science)
Now,
4:14
S…
Speaker 2 (dictation-t1-science)
hook the part I bent out into the rubber band that's holding the straw together.
4:18
S…
Speaker 4 (dictation-t1-science)
No,
4:19
S…
Speaker 2 (dictation-t1-science)
not that way.
4:20
S…
Speaker 2 (dictation-t1-science)
It'll fall off.
4:21
S…
Speaker 1 (dictation-t1-science)
That's right.
4:22
S…
Speaker 1 (dictation-t1-science)
Turn it over.
4:24
S…
Speaker 4 (dictation-t1-science)
Now,
4:25
S…
Speaker 2 (dictation-t1-science)
hook two or three more paperclips on.
4:27
S…
Speaker 2 (dictation-t1-science)
It's hard to say how many we'll need.
4:30
S…
Speaker 2 (dictation-t1-science)
The idea is to get the diver to be almost all the way submerged,
4:34
S…
Speaker 2 (dictation-t1-science)
but not quite.
4:35
S…
Speaker 2 (dictation-t1-science)
We can put it in this tall cup of water to test it.
4:38
S…
Speaker 1 (dictation-t1-science)
Hmm.
4:39
S…
Speaker 3 (dictation-t1-science)
What do you think?
4:41
S…
Speaker 3 (dictation-t1-science)
Too buoyant?
