Presley: Hey everyone, it's Presley@actoutgames.com
here and today is Science Sunday and I am
going to be teaching my mom a little bit of
Geology.
Mom: (laughs)
Presley: Not Geography but Geology. I used to get them confused all the time.
(intro music)
Presley: Ok, so first let's talk about how
I got these amazing samples. And I got them
from the girls in science day at the Denver
Museum of Nature and Science from the rock
and geology clubhouse. There was this booth
and there was kind of a contest where you
would post a picture on instagram and the
best picture got these.
Mom: Yes.
Presley: As well as this awesome geology book.
So we won and we got these amazing really
cool geology things that I have been absolutely
in love with and now I just want all of them.
Specifically I want all of the crystal gems.
Mom: Yes.
Presley: I want the crystal gems. So thats
garnet, ruby , sapphire.
Mom: So that was very nice of... Karen the
Geologist to send us these. Yes?
Presley: Yes. So let's talk about the gems
that she sent me. Ok. So I can't find the
box for this one but this is Pyrite which
is easy to tell. I know some gems by heart.
Mom: OK
Presley: I know exactly what they are. So
this is Pyrite. I don't remember where it
is from because I don't have the box. But
it's really pretty and it's also Pyrite also
known as foul's gold. It's called foul's gold
because when they are mining people would
see Pyrite and think it's gold and it's called
foul's gold because fouls would think it was
gold.
Mom: Uh um.
Presley: So yeah.
Mom: And do you think they would try and sell
it?
Presley: (shrugs) Maybe it's called foul's
gold because fouls bought it too.
Mom: Uh um.
Presley: I don't know. But this is Amethyst
which forms in geodes. And I really like Amethyst
it's one of my favorite gems.
Mom: It is your favorite.
Presley: Also, my favorite crystal gem.
Mom: And what is a geode?
Presley: And a geode..We actually have a geode
over here. It is a rock so it looks like this
on the outside. And then you smash it with
a hammer and there's cool crystals inside.
And some of these happen to form Amethyst.
And I know that from a Steven Universe video.
Mom: (laughs)
Presley: I learn a lot about geology just
by watching Steven Universe.
Mom: You sure do.
Presley: This is Citrine from Brazil.
Mom: OK.
Presley: And I my gemsona is Citrine.
Mom: Your what?
Presley: Gemsona.
Mom: You have a gemsona?
Presley: Yes.
Mom: (laughs)
Presley: Yes
Mom: OK
Presley: And she's Citrine. And this is Citrine
so it has this white and then the actual color
of Citrine on the top.
Mom: Ok.
Presley: Which is cool because her gem looks
like this.
Mom: And do we know anything about Citrine?
Computer: Citrine
Presley: This is Citrine actually. Actually
it's called Citrine not Citreen as I thought
it was called.
Computer: Citrine.
Mom: Citrine is a glassy yellow variety of
Quartz.
Presley: Yes, it is a.. so this is Citrine
apparently. I didn't know it was called Citrine.
Computer: Citrine
Presley: Citrine
Computer: Citrine.
Presley: Why is it called Citrine? I thought
it was Citreen. It has an E.
Computer: Citrine.
Mom: Ok
Presley: Anyways, Citrine. And apparently
my OC's name has been completely different
than I thought it was.
Mom: Oh my God, your gemsona?
Presley: Yes my gemsona.
Mom: Has been wrong this whole time?
Presley: Yes her name, I called her Citreen
when she is Citrine.
Mom: Ok
Presley: She has had a name change in the
last 5 seconds.
Computer: Citrine.
Mom: OK
Presley: Anyways. It is a yellow to orange
kind of Quartz. Then we have Galena. Which
I though was Gal-ana. This whole video should
be called Presley can't speak English. So
this is Galena apparently and it is kind of
in a squarey shape. It's just.. and it's really
sparkly. Galena not Gal-ena as I thought it
was called. Galena also called lead glass.
Lead glass that's kind of a weird name but..
oh well. Is the natural mineral form of lead.
So..
Mom: Hmm.
Presley: So..
Mom: And this one is from Mexico.
Presley: Yes, Mexico.
I can speak a little bit of Spanish. El nino
come pan y la manzana sopa. Anyone who speaks
Spanish is probably looking at the screen
weird right now.
Mom: So this is Galena. Galena is one of the
most abundant and widely distributed sulfite
minerals.
Presley: Galena is the main ore of lead used since
ancient times because of it's somewhat low
melting point it is easy to liberate by smelting.
I wonder why it's not in Minecraft then?
Mom: It's not in Minecraft?
Presley: It's not.
Mom: Interesting. OK. Next one.
Presley: Yes, Galena. Very pretty. Very sparkle.
And.. very sparkle.. that is how to say words.
And this is native copper but copper is very
very very commonly used in lots of things.
There is a lot of copper down here from copper
wires from past science sunday's. But this
is copper and it's pure like form so it's
not all melted into a wire or anything. And
copper is an amazing conductor of electricity.
Which I like.
So you could just go like.. buzz..buzz with
this ore.
Mom: OK What's it's symbol?
Presley: Cu
Mom: (laughs) Very good.
Presley: Cu Cu Cu Cu
Mom: Yes, it has a very high thermal electrical
conductivity.
Which is what you said. Awesome.
Presley: Yes, pure Copper is soft and malleable.
A freshly exposed surface has a reddish/orange
colors. So this one is kinda starting to turn
green. I don't know if it is something else.
Oh well. The metal and it's allows have been
used for thousands of years. In the Roman
era Copper was principally mined with cyprus
hence the origin of the name of the metal
as сyprium (metal of Cyprus), later shortened
to сuprum. Its compounds are commonly encountered
as copper(II)
Beautiful. It's actually not as soft as it
says in the article.
Mom: So this says- Architectural structures
built with copper corrode to give green patina.
Presley: So that's probably what this is.
Patina.
Mom: Patina.
Presley: This is quartz from Arkansas. I have
a friend that lives in Arkansas.
Mom: OK. Can you tell us anything about Quartz?
Presley: It's in Minecraft.
Mom: And what does it do in Minecraft?
Presley: It looks fabulous. In Minecraft.
That's pretty much always does. It looks cool
and this looks absolutely nothing like the
Minecraft version. The Minecraft version...
this is not white. I guess the Quartz at the
bottom of the Citrine looks more like the
Quartz in Minecraft. This kind of Quartz from
Arkansas does not look like the Quartz from
Minecraft at all because the Quartz from Minecraft
is pure white. While this is kind of a clear
coloring. So Quartz is the second most abundant
mineral in the earth's continental crust after
feldspar. Feldspar. Feldspar. Feldspar. I
am probably saying that wrong but I don't
know. It's made up of a continuous framework
of SiO4 silicon–oxygen tetrahedra, with
each oxygen being shared between two tetrahedra,
giving an overall chemical formula of SiO2.
Science! Yes, and also it's very pretty. It
also apparently a news place. Is this chrysocolla.
Is that how it's pronounced?
Computer: chrysocolla
Presley: Yeah chrysocolla. Which is how I
thought is was said. From Arizona and it just
fell over. And it is this beautiful color.
Mom: Uh Um.
Presley: And there is also a lighter variety
of the color and black. So it 's kind of feels
like a rock. It doesn't feel like a gem, it's
not very smooth. But when it's smoothed out
it's really pretty. So chrysocolla is a hydrated
copper cyclosilicate mineral with formula:
Cu2-xAlx(H2-xSi2O5)(OH)4·nH2O (x<1).
Mom: (laughs)
Presley: or (Cu,Al)2H2Si2O5(OH)4·nH2O. Whatever.
Science! But Chrysocolla has a cyan blue green
color.
And it's a minor ore of copper, having a hardness
of 2.5 to 3.5. The name comes from the Greek
chrysos, "gold", and kolla, "glue", in allusion
to the name of the material used to solder
gold, and was first used by Theophrastus in
315 BCE.
History! All the things you learn by looking
at pretty rocks.
Mom: OK. The last one is...
Presley: (drum roll) Hematite according to
the Spanish dictionary. It's very sparkly
and it looks like galaxies and it looks like
space and I like it. Because space and pretty
and black and sparkles. And Hematite, also
spelled as haematite, is the mineral form
of iron(III) oxide (Fe2O3), one of several
iron oxides. Hematite crystallizes in the
rhombohedral lattice system, and it has the
same crystal structure as ilmenite and corundum.
I was about to say lettuce system. So hematite
crystalizes into the rhombohedral lettuce
system, according to my brain.
Mom: Latice system? Is that what it's supposed
to be?
Presley: Yes it's a lattice system not a lettuce
system as I thought it was. It the lettuce!
Lettuce.
Mom: OK. Well I've learned a lot.
Presley: So that was a really awesome time
and I enjoyed looking at all of the things
and you can learn actually lots of things
just by.. It all started by just looking at
a pretty rock and then we learned about history
and really really..
Mom: Origins of words.
Presley: Really really long chemical formulas
that are hard to say. (laughs) So yeah, thank
you for watching and I will se you tomorrow.
Bye!
Mom: Bye!
