I that today we're gonna look up states of matter
00:05 - 00:08
and how states of matter affect resistance.
00:10 - 00:12
This bottle is a prime example.
00:13 - 00:15
The ass of the bottle is solid.
00:16 - 00:18
Therefore, the state of matter is solid.
00:18 - 00:18
It's plastic.
00:20 - 00:23
The inside of the bottle contains water that we can
00:23 - 00:26
see that is the liquid within that.
00:28 - 00:32
But also there's something you can't see, which is that's
00:32 - 00:32
a Gus.
00:33 - 00:34
That's its state of matter.
00:35 - 00:41
So if you're thinking about these sorts of things you're
00:41 - 00:46
thinking about, kind off tiny, tiny, tiny, tiny particles.
00:49 - 00:54
Now, this plastic I wouldn't be able to move through.
00:56 - 01:00
The particles are too closely packed, and therefore I'd be
01:00 - 01:01
unable to move through them.
01:04 - 01:07
Anyone that's gone swimming or seen a boat knows that
01:07 - 01:09
we can move three water.
01:10 - 01:14
It causes less resistance against our movements than a solid
01:14 - 01:15
object would.
01:15 - 01:18
We can't run into a brick wall, but we can
01:18 - 01:22
swim through water just as I can.
01:22 - 01:29
Walk along the road through air is actively in order
01:30 - 01:34
to move faster through the EC, we need to be
01:34 - 01:40
able to streamline or create a steam, streamlined body shape
01:40 - 01:42
or home jet shape.
01:44 - 01:47
This is why often people do cycling or something similar?
01:48 - 01:50
Well, we're clothing that isn't Maggie.
01:50 - 01:51
It's streamlined.
01:51 - 01:54
Therefore, won't pull them back and create more air resistance.
01:56 - 01:59
The same is a rocket is designed to make sure,
02:00 - 02:02
but it rather than resists the air.
02:03 - 02:04
It cuts through it.
02:05 - 02:10
Oh, a speedboat, The bottom of which will be really,
02:10 - 02:14
really, really ridged with very, very sharp edges.
02:15 - 02:20
The sharp edges effectively cut through the water, making it
02:20 - 02:23
much easier for the objects to flow through.
02:26 - 02:28
If you had a speedboat with exactly the same power,
02:30 - 02:33
one of which didn't have a ridged a streamlined base
02:35 - 02:38
on one of which did, if you exactly the same
02:38 - 02:45
force early, the speedboat bottom that was streamlined would go
02:45 - 02:47
fast on.
02:47 - 02:50
The one that wasn't would go slower, even though the
02:50 - 02:56
same force, the push from the engine is exerted with
02:56 - 02:59
the same force and therefore should be the same speed
03:01 - 03:01
as Primary seven.
03:02 - 03:04
Today you're going to design your own experiment to look
03:05 - 03:05
at streamlining.
03:07 - 03:10
That is to say, you can do a number of
03:10 - 03:16
things. You could create a plastic bottle rocket by using
03:16 - 03:20
a long, large, empty plastic bottle, creating some form of
03:20 - 03:23
rocket to stick to the top of it and then
03:23 - 03:26
squashing your bottle on letting the rocket fly away.
03:29 - 03:32
You could potentially think about the streamlining of a boat
03:33 - 03:36
using again another bottle or carton or something similar you
03:36 - 03:38
found in your house, preferably empty.
03:40 - 03:42
Cut out the bottom of it.
03:43 - 03:46
Create the hull of the tapes and think about different
03:46 - 03:49
ways. You can change the base of the vote to
03:50 - 03:51
make a more streamlined effect.
03:53 - 03:54
May be using tinfoil law.
03:55 - 03:57
Kalinda. Fill whatever you can find at home.
03:58 - 04:01
Think about his idea that you're cutting through the water
04:03 - 04:06
well. Finally, what you could do is use a plastic
04:06 - 04:10
bottle or another cartoon that is waterproof and fill it
04:11 - 04:13
with a few rocks or stones or something that's more
04:14 - 04:18
dense and heavy than water along with some water, too.
04:20 - 04:23
Then drop it to maybe the bottle of your sink.
04:23 - 04:24
That's one of water or the bottom.
04:25 - 04:27
Your bath, that sort of water in time.
04:27 - 04:30
How long it pigs for it to reach the bottom,
04:31 - 04:33
then do it the same thing again.
04:34 - 04:38
But maybe add fins or a nose cone or something
04:39 - 04:43
else to try and make your object more streamlined, as
04:44 - 04:46
you do this on to make notes.
04:46 - 04:51
No scientific findings hypothesize gas.
04:52 - 04:57
Talk about what might make something more streamlined, less streamlined.
04:59 - 05:03
You could also even look at paper aeroplanes and think
05:03 - 05:06
about how to make the most streamlined paper aeroplane.
05:09 - 05:10
Obviously, that wouldn't work so well going through water.
05:11 - 05:14
But it would add to the idea of cutting through.
05:16 - 05:17
I can't wait to see how you get on.
