(upbeat piano and harp tune) – [Voiceover] This module is sponsored by the Children’s Services
Council of Broward County. (kazoo noise) – [Penny] Hi! – Hi! – I’m Penny. – Nice to meet you. – Nice to meet you, and these
are the KidVision VPK kids. – Hi kids!
– We’re here today to find out about marine research. – Well, Penny and the KidVision kids, you’ve come to the right place because here at Nova
Southeastern University’s Oceanographic Center, we have all sorts of really interesting marine research going on for you guys to learn about. We’re gonna start over at our land based coral nurseries. – Keri, can you tell us
what’s inside this tank? – Sure, Penny. This is a variety of corals that you would see in
the natural environment here in South Florida,
right on our coral reefs. We have several different species of coral for you guys to look at today. The main one that we have are all these branch-y
ones you see out here. Like these, this is called staghorn coral. What do you guys know about coral? – They look like a rock
but they’re actually living and they also give homes
for other creatures and they grow on rock and
there’s many different kinds. – [Keri] These corals grow
and make all their branches, it gives great habitat for fish and other little animals
to come and take shelter in those branches so
predators can’t come by and get them. It’s very important for
the fish here in Florida that they have all these healthy corals so that they can have somewhere to live. – It feels like hard rock. . . – Does it feel a little slimy? – But it feels that slimy, wow. – [Keri] Then they grow from up here. You see how that’s nice and white? That’s because it’s growing actively from these points and that’s where the new coral is growing and being formed. – [Penny] So you grow these here and then you transplant
them into the ocean? – [Keri] Yep. And we can actually do a little bit of that today. Do you guys wanna help me make new coral? – Yes! – Does that sound fun? We start all our new corals
on these little cement plugs and then we’re gonna
take one of our corals that’s ready to be cut. – So we’re going to grow coral from coral? – We are. We are going to essentially prune the coral, glue it onto a new rock, and one day that’ll grow into a new coral. That’s how this coral started; one day it was only this big and now, about nine months later,
it looks like this. The corals don’t have brains
so it doesn’t hurt them. This is actually just like
super glue, very similar. So here, you gonna start, Matilda? – Yeah. – Just put it in there and now
hold onto it, hold onto it. – [Penny] You have to hold on tight. – Yep, and just wiggle
it around a little bit. And now we’re just gonna
lay it down like this. Put it on there, and now I’ll hold onto it and we’ll just lay it
down so it can harden up and then in just a few minutes
it’ll be stuck to the rock and we can put it back
in our coral nursery to grow into a new coral. Remember we were at the
coral nursery outside, and now we brought one
of those pieces of coral from the nursery upstairs so we can get a closer look at it under
one of our microscopes. This microscope’s great because it has this camera on the top so it’s actually sending the image right to the screen. So what we’re looking at on the screen is actually the coral that’s here in the dish under the microscope. Now you see this right here? – Yeah.
– [Keri] It is a live coral up close through the microscope. This brown area around
here is just it’s tissue, sort of like it’s skin, and then in here is where the mouth is. These little bumps you see right here are the coral’s tentacles. And each one of these little
cups is a coral mouth. So this is a whole colony of individual animals,
each one with a mouth, it’s all living together in this skeleton. This microscope uses
these lenses that it has, both in the eye pieces and this lens, to make everything bigger so that we can look at it more closely. – What other tool makes
things look bigger? – A magnifying glass. – Good question, because a microscope makes things look bigger
more than a magnifying glass. – [Penny] That’s right!
(kazoo noise) – Hi guys, I’m Doctor Tami Frank. I run the Deep Sea Biology Lab. What I want you to do is touch the outside of that, and see how papery thin that is? – [Children] Yeah. – [Tamara] That’s because these guys spend all their time swimming in the water so they have to be really light. This guy spends all
his time on the bottom. Now feel how hard and heavy that is. (gentle techno drums) – Okay, now, what do you think these little berries are there? It’s eggs. That’s how these
guys carry their eggs. – [Penny] Wow, that’s so many eggs! – [Tamara] So when the
eggs are ready to hatch, then they just go out into the water. Now you see the color of this guy, and you see the color of this guy? When we first sort the animals, we first look at the colors. This is Charlie and this Eric.
– Hello! – And they’re gonna show
you how we sort things out by their physical characteristics. – Okay guys, so we’re gonna separate these based on their physical properties so by that I mean their color,
their size, and their shape. So if you see this one right here, this one’s nice and red, right? So we’re gonna put that over here with the other red shrimp. And now this one, see how
this one’s nice and white? We’re gonna put that over here with the other white shrimp. And now, did you see how both
of those were really big? Now we’re gonna go to one of these guys. See how small that guy is? So we’re gonna put him over here with the other small shrimp. You guys think you got it?
– Yes. – You guys wanna do it?
– Yes. – Here we go, why don’t
you guys try to do some? (gentle techno drums) – [Charlie] A lot of them
we have to look at under the microscope to see the differences and then we’re gonna ID them based on their different
physical characteristics. (kazoo noise) – Today we’re gonna
talk a little bit about tiger sharks. Do you know
what a tiger shark is? – Yes. A tiger shark has stripes and it has a brown back and a white belly. – They have shoulders that are holes that they use to breath out. – Those are actually called gill slits and that’s what allows
sharks to breathe underwater. As they swim, the water
filters through their gills, and they absorb the oxygen. And now I’m gonna show you
where tiger sharks move. His name is Harry. Harry, actually during the warmer months, he moves offshore into the colder water and we see him acting
as an open ocean shark, and then when it gets colder, he actually heads down
into the Caribbean Islands, travels by the Bahamas here,
you can see us here in Florida, and then comes back down to Puerto Rico and the Virgin Islands and
spends a bit of time there. Sharks are the apex, or
top, predators of the ocean so they eat a lot of different things and they have to be able to
have strong teeth to do it. So this is a shark jaw, and you’ll notice there’s multiple rows of teeth. – [Child] Yes, and they’re very sharp. – [Alexandria] Yeah, you can touch them. Feel how sharp those teeth are. The teeth of a tiger shark are almost like a saw; they have these serrated edges and they allow them to
break through turtle shells. Could you imagine? And they may even lose a tooth. And what happens is, because they have these multiple rows of teeth, they can fill that tooth back in and have it be replaced. They don’t even have to go to the dentist. Their jaw is not attached to their skull. Remember, sharks don’t have any bones, they’re all made of cartilage. So there are lots of
different types of sharks. This is a stuffed animal of a blue shark. Now let’s look at the fins. So this is the dorsal fin right here, and I actually have a real dorsal fin. Where it would go on the
shark is on it’s back. This would be a pectoral
fin, or like an arm fin, and that would go right here on the shark. They use this big, long
caudal, or tail, fin to move side to side. (gentle techno music) – [Penny] So if we were sharks, we would our tails, right? So everyone move your tails like a shark. Move your bottom side to side and now let’s bite like a shark does. Protrude out. Right, good biting! Thank you so much for showing us NSU’s Oceanographic Center today. We really had a good
time and learned a lot about being marine scientists today. Thank you! – Thanks for coming
kids. Thank you, Penny. – Bye! (kazoo noise)
