Hello and welcome to stem story with Mr Ewing.
- 00:04 - 00:07
You know, I have been walking around your neighborhood or
- 00:08 - 00:11
your backyard or around the school and see some plants
- 00:12 - 00:14
and one to yourself how they get there.
- 00:15 - 00:17
Sometimes I'm looking at flowers or trees.
- 00:18 - 00:21
That's probably been there for a really long time, and
- 00:21 - 00:23
I think, How'd they all start?
- 00:25 - 00:27
We're gonna learn today about the life of a seed.
- 00:29 - 00:32
No, we think about plants in this world.
- 00:33 - 00:35
A lot of our plants, not all of them.
- 00:35 - 00:38
But a lot of our plants start their life as
- 00:38 - 00:38
a seed.
- 00:39 - 00:42
Now we've read all kinds of stories about magic seeds
- 00:43 - 00:43
and things.
- 00:44 - 00:45
Seeds conduce A.
- 00:45 - 00:47
And to be honest with you, it's not magic.
- 00:48 - 00:51
It's all about the science of a seed, and seeds
- 00:52 - 00:55
come in all kinds of different shapes, sizes and colors.
- 00:56 - 01:05
Some seeds come super small, some seeds super big, and
- 01:05 - 01:05
there's even seeds.
- 01:06 - 01:07
They're really crazy.
- 01:08 - 01:12
Strange, like the's Net nutmeg seeds and don't be schooled
- 01:13 - 01:14
by the size of a seed.
- 01:16 - 01:19
This tiny little seed produces one of the largest things
- 01:20 - 01:20
in the world.
- 01:22 - 01:22
Sequoia Tree.
- 01:25 - 01:30
No, you probably have seen seeds around your house in
- 01:30 - 01:35
kitchen, some flower seeds, red beans, lima beans.
- 01:35 - 01:37
A lot of the beans that we use in our
- 01:37 - 01:42
cooking come to us dried, and those beans actually have
- 01:42 - 01:44
planted. A lot of times will grow into a plant,
- 01:45 - 01:49
but they're doing something that we like to call being
- 01:49 - 01:53
dormant and dormant, sort of away of like, you know,
- 01:53 - 01:56
like a bear and the winner will hibernate.
- 01:57 - 01:58
We'll want to see this dormant.
- 01:59 - 02:01
It's almost like it's sleeping.
- 02:01 - 02:03
It's not really sleeping because the seat can't sleep.
- 02:04 - 02:08
But it's an estate where it's not actively ready to
- 02:08 - 02:08
go toe.
- 02:09 - 02:12
Grow to a plant now, in order to grow to
- 02:12 - 02:14
a plant that seeds gotta make it to the ground.
- 02:15 - 02:17
And there's some really cool ways that seeds can make
- 02:18 - 02:18
it to the ground.
- 02:20 - 02:23
One of the easiest ways we think about is a
- 02:23 - 02:27
seed falling from a tree or plant down to the
- 02:27 - 02:28
ground. Especially like these.
- 02:29 - 02:32
I like to call a helicopter seeds, and the plant
- 02:32 - 02:35
has a little bit of leave and it catches the
- 02:35 - 02:37
wind and it floats down on the ground and some
- 02:37 - 02:40
of them, like maple leaves, twirl almost like a helicopter.
- 02:43 - 02:45
Some seeds get to the ground because they're inside of
- 02:45 - 02:48
fruit that grow on trees or bushes and that fruit
- 02:49 - 02:52
drops to the ground, and over time those seeds will
- 02:52 - 02:53
make it into the ground.
- 02:54 - 02:59
No, some seeds get blown off their plant and get
- 02:59 - 03:04
carried in the wind, and slowly they'll drift around and
- 03:05 - 03:06
they'll make their way to the ground as well.
- 03:07 - 03:09
Now this, I think, is the most interesting way of
- 03:09 - 03:11
seed can get to the ground now.
- 03:12 - 03:16
Birds and animals loved fruit and Berries and seed pods
- 03:16 - 03:17
off trees.
- 03:18 - 03:21
No, they digest or they eat the seeds.
- 03:22 - 03:25
So you're thinking, Mr Ewing, how did those seeds make
- 03:25 - 03:26
to the ground?
- 03:27 - 03:30
Well, seeds most the time.
- 03:30 - 03:32
Don't get digested by the birds.
- 03:32 - 03:35
Just the fruit of the meat of the berry or
- 03:35 - 03:36
the fruit that they're eating.
- 03:37 - 03:40
So those birds and animals, Well, they pooped him out.
- 03:41 - 03:42
And when they put mount guess where they go.
- 03:43 - 03:44
You're right to the ground.
- 03:46 - 03:48
So ones those seeds make to the ground.
- 03:49 - 03:51
Every seed needs sort of the same type of thing
- 03:52 - 03:54
that order for it to grow into a plant, need
- 03:54 - 03:57
some sun, I need some air, I need some water,
- 03:58 - 04:00
and it also needs the soil.
- 04:00 - 04:03
But we've already talked about that because they're seeing needs
- 04:03 - 04:03
to be in the ground.
- 04:04 - 04:06
But it has the right conditions.
- 04:07 - 04:10
The seed well, actually wake up.
- 04:11 - 04:13
Now again, it's not really asleep, so it's not waking
- 04:14 - 04:17
up. But it's using its stored energy to actually start
- 04:18 - 04:19
to grow into a plant.
- 04:20 - 04:21
And that's something that we call germination.
- 04:22 - 04:25
Germination is when the seed is put into the right
- 04:25 - 04:28
environment, it actually starts to sprout its roots.
- 04:29 - 04:33
And then a very small shoot that's right here will
- 04:33 - 04:34
come up out of the seed.
- 04:35 - 04:37
Now it will slowly push its way up through the
- 04:37 - 04:40
ground or whatever environment that it's growing in and actually
- 04:41 - 04:41
come to the surface.
- 04:43 - 04:46
Once it comes up to the surface, we have this
- 04:46 - 04:49
sprout stage, but then the next stage is something that
- 04:49 - 04:50
we called a seedling.
- 04:51 - 04:53
Now, once we get to the seedling stage, our plant
- 04:54 - 04:58
will continue to grow till it's a regular, full grown
- 04:58 - 05:02
size. That could be couple inches, too, like we saw
- 05:02 - 05:05
in the Sequoia tree, where it's hundreds of feet tall.
- 05:06 - 05:10
All depends on the plant's life cycle, but that's the
- 05:10 - 05:12
basic idea of the life of a seed.
- 05:13 - 05:16
So next time you're walking around and you're looking and
- 05:16 - 05:18
you see some plants, you can point to him say,
- 05:19 - 05:21
Hey, I know how that plant out started or I
- 05:21 - 05:22
know how that tree got started.
- 05:23 - 05:26
It's through germination when that scene made to the ground
- 05:26 - 05:28
had everything it needed to get started.
- 05:29 - 05:30
So, you know what I'd love for you to do
- 05:30 - 05:31
is to go outside plant.
- 05:32 - 05:34
Some seeds are actually just take a walk around and
- 05:34 - 05:38
see what you can identify as something that came from
- 05:38 - 05:38
a seed.
- 05:39 - 05:40
Go out and have a great day.
