Hello, I am Jared, and welcome to Fun Science Demos.
I have a little friend with me here today, a
little rabbit, Hey, get back here! I think he is
excited about what we are going to be
talking about because the big idea is
energy. How did this little guy get the
energy to move?
Well, inside he has three batteries that
make him move.
Those batteries give him energy. Where
do we get
our energy from? I know what you are thinking. We get it from food.
But let us think about this. Where does
the food
get its energy from? So we have changed our
set up to show you
how plants get that energy. Through
science
we have discovered that plants get their
energy from the sun.
The sun gives us heat and light and
plants have the neat ability to take
that light
and store it as energy in its 
 leaves, in its
fruit and its roots. And when living
things eat that plant,
we get the energy from that plant and it
allows us to move and allows our heart to
beat and allows us to think.
Just like that rabbit. Our energy does not
come from batteries,
it comes from the sun. Notice I said that
almost all living things get their
energy from the sun. Well,
right here, off the coast of South
America
in the 1970s, scientists
discovered this community of life
that lives really, really deep in the
ocean. It is so deep the sunlight cannot get
to it.
And they- that community of life-
does not get its energy from the sun
because there is no sunlight.
It actually gets its energy from the
heat of the earth.
Now that is pretty cool. Do you know, scientists have a really neat name for how plants
take that energy from the sun and store
it. It is called photosynthesis.
I know it sounds complicated but when
you break it apart it is actually pretty
simple.
Photo means light and synthesis
means to make. Do not forget to check out
our links in our video description.
Science is so cool. Thanks for watching.
