Hey, science lovers, Molecular Mike here coming to you from this wildlife
care center, where they take care of all different kinds of injured or
abandoned wildlife. It's a pretty big job for all the great
folks that work here. Taking care of all the animals were all different
kinds of living things, including animals have certain things they need in order to
survive. Just like you and me. What kinds of things did they need?
We'll learn about that and more today on soaring into science.
Taking care of animals like these pelicans back here is a really important
job. You see all living things when they're out in the wild. They have to
compete for natural resource is and the animals that have the
best adaptations to compete for those resource is, we'll be able to live and
survive and pass those adaptations off to their
offspring. It's a process of natural selection. Well,
sometimes that process of natural selection gets interfered with when
people come into the environment. You see people will come in and
sometimes they'll fish or they'll drink things from six
packs and they'll leave these things around, and the pelicans like these
will get caught up in them. Sometimes they will swallow the
fishhooks, and that's when they have to come to some place like this wildlife care
center, where people need to try to nurse them back to health.
Because if they didn't, they wouldn't be able to survive back out in the wild.
Here at this wildlife care center, they take care of all different kinds of
animals, with many different than sometimes unusual problems.
Whether it's a baby bird whose parents have disappeared,
a turtle who shell has been cracked,
an abandoned bunny rabbit or any wild
animal that can no longer take care of itself. For whatever reason, it
confined help and people toe lend a caring hand. Here,
when these animals are ready and healthy enough to compete for
nature's limited resource is they'll be released back out into the
wild, where they can live the remainder of their days.
Well, here we are. Welcome to
the
you know, millions of living things have adapted to living in many
different kinds of environments all over the earth.
It's a matter of fact, and environment is a place on the earth that
has certain kinds of conditions that living things must adapt
to. You'll find living things in desert
environments, rainforests,
wetlands, grants, Linz
oceans and even your own backyard.
Some of those environments are more conducive to population growth of
different kinds of living things than others are. You'll find many
mawr living things in a rain force than you will in a desert.
Why is this? Well, it has to do with the available
resource is in an environment. A resource is something
that satisfies a need. Animals, little
environment need food for energy,
water to help them to stay hydrated.
Shelter for protection and
space so that they can successfully compete for resource
is variations in the amounts of these needed.
Resource is will directly affect the populations of living
things. When you're comparing things like deserts and
rainforests, you can guess which one of these resource is
makes the biggest difference. Do you know what it is?
If you guessed the water, you would be absolutely
correct. Desserts are so dry that they're simply not enough
water to provide. For as many living things as you're able to find in a rain
forest, you can very easily make an
environment of your own with just a few simple materials.
To do this, you're going to need a two liter
bottle with the top cut off
some soil, a small
plant,
some water
plastic wrap
and a rubber band.
The first thing that you're gonna want to do is to add some
soil to the bottom of the two liter bottle container.
Here.
Not too much. Make sure you're not only a few centimeters to begin
with. Next, you want to put your plant on
top of that soil.
You want to do this gently that you don't damage. Whatever
planted is that you've chosen, and if it takes up a little bit
of extra room, just fold the leaves down inside gently
there. Next. If you need to, you're gonna have to use
some of the extra soil to fill in around the plant. If it's a small
one. Now add some water to the plant
because all living things need water to keep themselves hydrated.
And finally, you're gonna put the plastic wrap over the top
and then used a rubber band toe.
Hold the plastic wrap on like
this, and there you have
it. The finished environment. The plastic wrap
will help to recycle the water that you put inside, so you won't have to
add it very often. This plant is able to produce its
own food for energy, but it will get some vital nutrients
it needs from the soil. This plant will be sheltered
from too much cold or too much heat inside the container,
and they're still space in here for to grow for a while. So there
you have it food, water, shelter and space
all in one convenient place. If you decide to make
one of these on your own, try different kinds of plants in
different kinds of environments. For example, over
here is one that I made off a desert
environment, and after a while your plants are going to get
big. And if you run out of space, well,
just use a bigger bottle or a bigger
container of something.
Ever wonder how animals survive in the wild? Although many animals have
adapted to living in different kinds of environments, there are certain things that all
animals need in order to survive. All animals need
food, water,
shelter and space.
How do animals get the things they need? Well, you can find out
in order. To do this, you'll need ah, package of wooden toothpicks and colors
Green, blue, red and yellow. Ah, stopwatch. Ah,
wide grassy outdoor space and some friends pick one
person to be the needs distributor. Everyone else can pick their own
favorite animal to be for the activity. Have the needs
distributor. Take the wooden truth, picks out to the grassy area and spread them
around the area. Now the fun begins. Each
color toothpick represents one of the things that all animals need.
Greenest food. Blue is water. Read his shelter
and yellow a space. When the needs distributor starts the
timer and says go, animals will have two minutes to search for
one full set of four toothpicks. If an animal
finds all four early, the animal should return to the base while the
rest keep searching. When time is up, all animals should return
to the base and think about what they have found that all
animals have enough food, water, shelter and space.
What do you think would happen to an animal in the wild
if it didn't have all of its needs met? That's food for
thought. Oh, by the way, be sure
to use Onley wooden toothpicks. The wood is biodegradable,
which means it won't harm the environment.
I recently visited the Museum of Discovery in Science. While I was at the
museum, I was lucky enough to meet Brian Sharpe, museums life
science manager. He was able to share with me an example. Each
category of vertebrate animals We started with this furry,
possibly Penelope. She belongs to one of five vertebrae
categories. Her category is called mammals.
As you can see, one characteristic of mammals is that their bodies
were covered with fur. There are also warm blooded, which means
mammals produce their own body heat through a chemical changes. Most
mammals also bear their young alive, and from there Brian
shared another of the museum's pets, a barred. Our
owls are classified as birds, another category of vertebrate
animals like mammals, birds air. Also, warm blooded
birds have some pretty distinct differences when compared to mammals,
For instance, the bodies of most birds are covered with lightweight feathers
that help them fly. Also, the majority of birds have their young
by laying eggs and speaking of laying eggs,
check out this guy. This is an indigo snake.
Snakes belong to another vertebrate animal classifications called
reptile. Most reptiles lay eggs like birds do,
but their body covering is very different. Reptiles are covered with
scales. Many people think steaks there must be slimy,
but that's not true. The scales are actually shiny and smooth.
Another way that snakes are different from birds and mammals is that reptiles
are cold blooded. That means they don't make their own heat
within their own bodies. Cold blooded animals get all their warmth from
their surroundings. Brian shared more cold blooded animals with
me fish fisher a lot like sneaks.
They're cold blooded lay eggs there, even covered with scales to.
But there's a big difference between fish and most other vertebrate animals.
Fish get their oxygen right out of the water they breathe. To
do this, fish have specially designed gills.
They also have fins to help them move through the water. The
last category of vertebrate animal is also cold blooded and lays
eggs. It's a category called Amphibian
Amphibian. Brian Sharpe. Shared With Me is an Eastern tiger salamander.
The word anthem Ian means to lives. That's
because they live the beginning part of the life in water, like fish
getting their oxygen directly from the water. But later on, when
amphibians are adults, they have to get their oxygen from the air.
Amphibians also different from reptiles and fish because their bodies air Onley
covered with skin, not scales. All those structural
adaptations on the different animals we saw help each one of them
survive in their own kind of environment as well as help us
to classify them scientifically.
No. Yes, it's me. Or
do I have a joke for you? I made it up all by myself.
You're this. Why did the chicken cross the
road? Are you ready for this? It crossed
it to get through the other side. You get
it? I think import under isn't for the chicken.
Cross the road but really it was not born with
so funny. You look
well. Make it with impress your more chicken crossed the road because
you will be changed box. Was I the one next to
the road? Hey, what? That is just not funny.
Speaking off. Did you know that you can use a computer? And
Ryan, you compare the way different kinds of animals for detective.
So But anything in what their environment It is
actually relatively simple. You could do a 30
computer like me. Don't get open.
Nothing. Computer Ryan, for the next one you see here on the street.
First, choose a type of environment for your animals.
For this example, I will choose a course
in the way. Therefore I will leave. Will make a
gray sky and some
snow on the ground down here. Perhaps we could
put a smile. You have right
here.
Your next step is toe. Pick some animals to place around your
perhaps I don't put day. Beautiful little blue
birdie appear in the sky
City green part. All here trying to get into that frozen
find boy. Friends surprise way
Put their beautiful wild out here and they
have a little grand bunny rabbit over here. Oh, yes.
And let's not forget. Are you
finished drying off? I will put some people with three types trees
here on here and over
here on how about some smaller ones here and
here and here and here. And finally here.
What? Now stand back and take a look at your
beautiful new picture. Which of the animals really is that?
I would have to say it was a mythical grab, but in this case
the other animals started out against especially
speaking on Dr Why did they cross the road?
Hey, because it was dying with ticket.
Here's another one. Why did the chicken cross the basketball
court? Because it's worth the referee calling
fouls. Get a ticket.
Our boy was not funny. Now if you will
excuse me, I must cross every one of my own. You know
the information superhighway.
Ah, habitat is a place in an ecosystem where an animal
usually lives. For example, an ecosystem may be
found in an environment where there are trees, lakes, streams,
caves, all sorts of other features. Ah, habitat
for fish in an equal system like a forest would be a
lake or stream. Ah, squirrels. Habitat would
be in the trees of that forest and the habitat
for a bat might be a cave in the same environment.
There are many different kinds of ecosystems found in many different
environments all over the world. The different parts of any
ecosystem must be in balance order for the living
things in it to thrive. If any habitats air changed
within an ecosystem, the living things in the ecosystem may
not survive well. Here is a model of an
ecosystem with the animals and their habitats. The animals rely
on each other as well as the plants in the ecosystem. For food,
the water supply looks like it's pretty good, and there's enough space and
shelter for the animals. There's balance in this ecosystem,
and there's enough food, water, shelter and space for
all the living things. But what if there were a fire that were to
destroy these trees? That change would destroy the
homes of these animals? Or what if people moved
in here? The animals would not be able to get water.
They wouldn't survive those kinds of changes when they're not
natural. Normal changes can be very harmful to any
habitat. Well, you can help to protect animal
habitats and protect our earth at the same time.
How well you can start by practising the three R's of
science. Reduce reuse
and you got it. Recycle.
When you reduce, it means you're going to use less of the
earth's precious resource is turn off the water when you
brush your teeth or the lights when you leave the room.
Hey,
and when you buy things. Look for reduced
packaging. What? I bought this basketball at a
local store. It was in a big been with a whole bunch of
others. Well, then there were other basketballs that were
boxes stacked up on shelves. I chose
this one because it was just a good as the other ones that were in the
boxes, but it didn't use the extra cardboard and
paper needed tour. Make the box around it. In that
way, I'm helping to save some trees
just because something's in a big, flashy package that doesn't
necessarily make it any better.
The second are that I talked about was green
use. When you re use something, it simply means to
use it over again. Many grocery stories use plastic
bags like these that often get thrown away after they're
used just one time. Well, how about switching to
cloth bags like these? They
hold all the groceries, their sturdy and
they're strong, and they can even be washed. And the
best part is that they could be used over and
over again. Now the final
are is recycle. When something is
recycled, it gets collected up and turned into something new.
The most common recycled materials air. These,
um, there's paper and
plastic, um, metal
containers and even glass containers.
As a matter of fact, even substances such as
motor oil can be recycled and used again. But you wouldn't put that on
a regular recycling bin. There are so many ways to
protect our earth that benefit the habitats of all living things.
You just have to know where to start.
Hello. I'm also Kirstie. I am the facility manager here at Broward
County. Be if I recycle when a truck first comes
on the property carrying recycled materials. First thing it does is
check in at the scale house where we'll record the city in which it
came from. He will move from the scale house to our tipping
floor, will dump newspaper, and I will go back and get
another weight. And then it will dump co mingle after the
material has been dumped on the floor. They will push up the material
on to feeders. From there, they will go up and will be sorted out
on paper line. There will be six people up there sorting out
contaminants do not belong in there. And that will be either plastic
bags or brown bags on the co mingle
side. What a co mingle is made up of is plastics,
aluminum, steel can in glass.
This will go up. A line on this will have to people in the very
beginning. Taking out the contaminants there do not belong.
From there. It will pass on to another set of two, where we
will have people on either side of it sorted out the plastics
like colors and types, and then on the other side of that we will
have a glass sorted out by color type. Also,
after this process is finished, the next move will be
to failed this up and make ready for shipment to the
vendors so they can make this into other, different products
other, whether other than what it may be at this time in point.
So what they will make out of plastic will be fabrics,
rugs and other types of material that they use in making rush.
The newspaper will be turned into newspaper again
within three days or insulation. The other
product that we sort out, which is phone books, will also be turned into
insulation. Also, that is a reason why
recycling is important and it helps to save
on landfill space.
A living things on Earth depend on the plants. Resource is for
survival. The earth as many resource is for people.
Besides food, water, shelter on space,
people have learned to use re sources such as coal and oil to
generate enough energy to power our homes,
run our automobiles and even travel great distances in
short periods. But there is a cost to using. Such
resource is the burning of coal and oil creates
gases that can cover art in a kind of blanket cause
and get toe warm over time. Known as the greenhouse effect,
this change in temperature can alter entire
ecosystems both on land and in the world's
oceans. Use of natural re sources such as coal and
oil also pollute the environment with acid rain
and oil spills permanently. Ultra precious
ecosystem The supply of re sources
such as coal and oil, are limited. They are known
as a non renewable resource is once they all
used up, they are gone where we get our
energy day. Fortunately,
there are alternatives. Waken get our energy from
renewable resource is such as hydropower for
moving water, the power of the
wind, solar power from the sun
and even geothermal power from deep beneath the earth's
crust. Development of renewable energy
resource is is of great significance toe our future and the
future of living things all over the world. Energy is there
just waiting to be harnessed. The future is up to you.
Well, we sure have learned a lot about animals today and
even a few things about protecting our earth and all the living things on it.
We found out about living things. Heat for Earth's resource
is and how the population of living things and an ecosystem
greatly depends on the available resource is we saw how
living things have different kinds of structural adaptations
and how habitat changes can be beneficial or harmful
toe living things. We even got to learn about the benefits of
reducing reusing and recycling as well
as the importance of developing renewable energy sources.
And that about does it for today. I need to put this recycling bin
out before the collection truck comes. This is molecular Mike signing
off work hard practicing safe science, and I will catch
you later. My friends
