Dancing Rocks! 4.2

One of the first things we're discussing

as part of the new material we're adding
today is how can represent

the idea of force or pressure in our body.

Metamorphic rock is either made

from sedimentary rock or igneous rock.

There are two things that change a rock

from igneous or sedimentary
into metamorphic.

One thing is heat,

and the other thing is pressure.

So first I asked the students
to come up with some ways

that they thought we might
be able to represent that idea,

and then I added into the mix

that they weren't actually allowed
to physically touch each other.

So we had to be creative about
how we were going to represent

that tension and pressure in our body

without actually physically pushing
on one of our partners.

If you imagine that you had
super hero powers

and you could like shoot
energy out of your hand.

So like our muscles are really stiff
like they are working hard.

And they came up
with some really wonderful ways

for us to express
that energy in our bodies.

Yes, I think so, I think
facial expressions really help show

whether something is easy or challenging.

Now that they've practiced the sensation
of creating force

within their own body,

we're going to add on some movement
of the lower body as well.

So, they'll do 16 counts of marches

and then 16 counts of that forceful
push against the air.

Stand tall. Let's try it with some music.

♪ (music) ♪

So slow.

♪ (music) ♪

Now can you push it in?

Push it.

Keep pushing, keeping pushing.

Push, push harder, come back.

March, let's march fast.

♪ (music continues) ♪

Push, push, push, push, push, push,

okay, all right, good, pretty good.

Now the group is going
to represent tectonic plates

by creating two teams
on either sides of the room

and will slowly advance towards each other

with that idea of pressure
or force meeting in the middle.

The students were going to say,
"Metamorphic. Metamorphic"

four times as they march,

and then stay in silence as they
do their pressure move.

All right, so we are going
to try it with the drum.

You have to say the words
and march twice, ready?

Five, six, seven, say it.

(students) Metamorphic, metamorphic.

Now lunge, lean, lean, lean, march.

That sequence of marches
and pressure or force

will be repeated four times through.

(students) Metamorphic, metamorphic.

Now stop, stop, stop, stop.

What happens when the plates meet?

And on the very last set,

rather than performing
that same lunging pressure pose,

the groups will come together

to create some kind of mountain
shape or mountain range.

You can make a pose where
you are not touching anyone,

or if you ask someone, "Can we reach
and touch each others' fingers?"

And they say,
"yeah, let's do it," you can...

It could be that one group collapses

under another or they could decide
to come together as a team

to make the peak.

You can let the students have some input
on how they create that last pose.

- Metamorphic, metamorphic.
- Two more times.

(students) Metamorphic, metamorphic.

Sounds. Keeping pushing.

- Again, go.
- Metamorphic, metamorphic.

- Metamorphic, metamorphic.
- Push.

♪ (music) ♪

- March.

Now, you have one more set of marches.

- Ready, march.

Hold it.

All right.
