Lesson video

Hi everybody, welcome back to your science lessons with me, Miss.

Roberts.

If you were here last week, then welcome back, and if you're new, then why don't you tell me your name? Fantastic.

What a beautiful name.

Okay.

Let's see what resources we need for today's lesson.

You are going to need a pencil and a pen.

Lenny, what on Earth are you doing? Sorry team, rudely interrupted there.

You're going to need a pencil and a pen, a ruler, a notebook, and some colouring pen- Lenny, what are you doing? He is so excited for today's lesson.

Go and pause the video and get the resources you need, and maybe your favourite Teddy as well.

Off you go.

Okay, we are ready to go.

Let's recap our learning from last week, and we'll do a quick bit of marking because I gave you some questions at the end of last lesson.

Question one said, a flower has a set of male parts and a set of mm parts.

The answer there was female parts.

Give yourself a tick if you did that last week.

If you've not done these from last week and you're new this week, firstly welcome.

And secondly, you can jump a little bit forward and go straight to the star words screen, and that's where you'll find the start to the lesson.

Okay, question two for the answers team.

The stigma at the top of a female part is sticky, so that mm can stick to it.

The answer there was pollen, well done.

Give yourself a tick.

And number three pollen is produced by mm, which is the male part, what's that male part called? Tell your screen.

Good job, it's called the anther.

Well done everyone, give yourself a pat on the back if you got those right.

Before we do our star words, I wonder if you can see all of these beautiful flowers behind me.

I wonder if you want to see some other flowers behind me, you're going to need to help me.

You're going to need to blow on the screen.

So are you ready? Rub your hands together.

And when I say go, you're going to go , and we're going to see if the flowers behind me change.

Are you ready? Rub hands together.

Faster.

Ready, steady, go.

Wow wee, look at all those flowers.

Do you know what those flowers are called? They're my favourite flowers, and these are called tulips.

I love tulips because they come in lots of different colours, like can see on the screen.

Shall we see what other flowers we could find.

Should we do that again and see which other flowers might come up? Are you ready, rub my hands together.

Ready, steady, one, two, three go.

Wow, oh wow.

I wonder if anybody knows what these flowers are called.

Hmm, good try.

These are flowers of the lavender plant.

So if we were in this field, we would smell lots of beautiful lavender.

I find lavender really relaxing.

So I'm going to keep lavender on in the background.

So my turn, your turn.

Star words, star words, star words.

The first word in the top left is fertilisation, your turn.

Well done.

My action for fertilisation is this, I'm going to make myself bigger.

Fertilisation goes like this.

Can you do that? So you have your small pollen here and it goes into the ovary.

Fertilisation, your turn.

Let's do that one again.

Fertilisation, you'll turn.

Well done.

Next word in the top middle is seeds.

Your turn.

Well done.

Seeds, your turn.

Good.

The next word is conditions.

Your turn.

I'm going to make the words bigger.

Let's do that one again.

Conditions, your turn.

well done.

And the next one is pollination.

Can you do that one, pollination? Well done.

The next one is a funny action and it goes like this.

You have your two fists together and you go germination.

Your turn.

Well done, germination.

I've got fingers going down and fingers going up and you'll find out why later in the lesson.

Germination.

Well done.

And the last one is disperse, your turn.

Disperse, your turn.

Well done.

I wonder if you hear those star words you can put your hands on your head during the lesson.

So I wonder who's going to hit some of them first.

Okay.

So we've done our retrieval quiz and our star words, let's learn about the life cycle of a plant.

So first of all, we have the stage of germination.

Oh, well done.

You've already spotted one of our star words.

Now germination is when a seed is in, well done, when a seed is in the ground and it makes a shoot out of the top, and it grows some roots out into the soil, that is so that it can start growing into a plant.

Let's find out what happens next.

As the seed grows and the chute comes out to the ground and grows taller and taller and taller, it grows a stem and leaves and flowers.

And under the ground, it grows roots into the soil, and we would then say it grows into a plant.

So once it's a plant you can see something purple on the screen on that plant, and that is called a flower.

That's called a, no not flour like you bake a cake with, a flower, like a beautiful flower in my background.

Let's find out what happens next.

Once the flower has grown it grows the male and the female parts like we've looked at.

On the anther of the male part there is pollen.

There is well done.

And the pollen is picked up by an animal or the wind, and it's blown or taken by the animal to an anther.

Remember the action for the anther.

Why did the action look like this? It wasn't because it was a crab it's because it was sticky, well done.

What sticks to the anther? Tell your screen now Pollen well done.

So your anther is sticky so that when the pollen is brought to it, it sticks to it.

So the pollen is stuck to the anther, sorry the pollen is stuck to the stigma, and that is called pollination.

Once the pollen is stuck to the stigma it then travels down the stigma and into what we called the ovary, because inside the ovary are something very, very small called ovules.

And you can see the ovule in the middle of the page there.

So you have pollen plus ovary equals fertilisation.

Do you remember that action? This was the pollen.

This was the ovary with the ovule inside it, and put together they are fertilised, which is called fertilisation, and together they make a seed well done.

So let's just look at that in words.

If you have the pollen, your turn.

Plus ovary, well done which has the ovule inside it, and put together they make a seed well done.

I want you to do that by yourself.

So my turn, pollen plus ovule equals seed.

Your turn.

Pollen plus ovule equals seed, well done.

And then now we have a fertilised seed that's ready to grow into another plant, but at the moment it's still inside that flower.

So how does it get out of the flower in order to get to the ground again and grow? Well, now we have seed dispersal.

Can you say that star word again, dispersal, your turn.

Well done.

And this is where seeds are dispersed, and they fall to the ground, and once they're in the ground, they can then grow into another plant.

So let's have a look at those key stages again.

First of all, you have germination.

Can you do the action? One, two, three germination.

Can you do it in a silly voice, germination, your turn.

Well done I love how you're doing the actions, going to make it really sticky in your mind.

The next stage was when it grows into a flower, well done.

Can you do the actions of flower where my fingers grow out like a flower, but I'm also going to grow tall on the top of my plant.

So flowering with the action.

One, two, three flowering.

Well done.

The next stage was when the the buzzy bee collects the pollen.

And so what was this stage called, can you remember? Well done, it's called pollination.

Well done, it's called pollination.

These are my sticky fingers with my pollen.

The next stage was when the pollen sticks to the stigma and travels down and finds the ovule, well done.

What was that stage called, can you remember? Can you tell your screen.

Well done, good try.

Fertilisation, well done.

Fertilisation, your turn.

Good job.

And lastly, I'm going to give the action, what's our final stage? Disper- well done dispersal, when the seed is dispersed and it goes into the ground and grows into another plant.

So once that seed is in the ground, it then germinates and starts growing a chute, and some roots, and the whole process starts again.

Wow, isn't that an amazing process team? I would like you now to draw this into your book so that it's sticky in your mind.

First of all, I'd like you to write your title which is the life cycle of a plant.

Please pause the video and write yourself a title in your books now.

Well done.

I hope you've used your neatest handwriting.

Okay, so now have a look at my drawing.

I have drawn the lifecycle of a plant.

My drawings aren't as good as I know yours will be but what I've done is I've left some boxes on the screen next to each drawing.

I would like you to do the same, but I'd like you to fill in the boxes for the stages of the cycle of a plant.

See if you can remember them without going back.

But if you need to you can jump back in the video and go and remind yourself of how to spell those words, using your star words page.

So pause the video and draw the life cycle and add those names of the stages in now, off you go.

Well done, I can't wait to see some of those drawings.

I can't wait to see some of your beautiful, beautiful work.

Well done team.

Let's keep going.

I think we need a bit of a cheer so far because we've done lots of listening and lots of drawing.

I'm going to do a awesome cheer, and this is where we go, awesome, because we've done such awesome work.

Can you do an awesome cheer for the hard work that you've done so far? Are you ready? One two, oh some of you don't have your hands ready.

Get your hands ready to beat on your chest, 'cause you are awesome.

Ready? One, two, three.

Awesome.

Well done.

Let's keep going.

So let's check if your answers were correct.

Next to the seed with the shoot and the roots you should have had germination.

Next to your plant with your flowers, you should have had flowering.

The one with a buzzy bee should be pollination.

The next one where you have your pollen plus ovule equals seed is fertilisation.

And then the last one with your seeds going to find some new soil is called seed dispersal.

I'm going to make my page bigger so that you can pause the video and mark your work.

Team, one thing that's really important is that you've spelt your words correctly.

I'm going to make it bigger one more time so that you can pause it once again and check that each of your stages is spelled correctly.

You'll notice that the suffix T-I-O-N is used, so make sure you spell your words correctly.

Can you pause the video now and check your spelling? Well done.

I was really impressed to see some of you editing that spelling there, 'cause some of those words are really tricky, so well done team.

Okay, now we're going to do some reading all about the stages of a plant.

So you need to be reading out loud to your screen, not just listening to me.

That's why Lenny here is going to be with me so I can be reading to him.

It's no good just listening to me because otherwise I'm doing all of the thinking and I want you to be using your brains as well.

So are you ready to grow your brain? You are? I think some of you aren't ready yet.

I said, are you ready to grow your brain? You are okay, can you say repeat after me? I'm ready to grow my brain.

You're turn.

Okay, I think I believe you now.

We are now ready to rock and do our reading.

So let's read out loud together.

One, two, three, germination, all new plants begin their life as seeds.

If the seed is placed in the right conditions, then the seed will begin to grow in a process called germination.

This involves a chute coming out of the top of a seed and roots beginning to grow downwards.

Team if that was a bit quick can you pause the video and read that page again, using your actions? Okay, I'm going to carry on.

One, two, three flowering.

After this, a plant grows a stem, leaves, and a flower is produced near the top of the stem.

Some plants produce many flowers.

So like you can see in my background here the lavender has got many, many flowers just for one plant.

So this is lots of lavender plants with lots of flowers on each plant.

Let's keep reading.

One two, three pollination, the flower produces pollen on it anther, which is then spread from the anther of the flowers to the stigma, in a process called pollination.

If you need to team, pause the video and read that again with your actions.

Well done.

There are some big words in this and you're reading really excellently.

So let's keep going.

One two, three, fertilisation.

From this point the pollen grows and travels down the stamen until it reaches the ovary of the flower.

It joins with an ovule in a process called fertilisation.

Pause the video and reread that section with your actions now.

And lastly, this is the last one team, you can do it.

Come on, roll your shoulders back, one and two, and three, and shake out your arms. One, two three, this is our last screen of reading today, so you've done really well.

Let's go one, two, three seed dispersal.

Over time, the ovule develops into a seed.

This will leave the plant being carried by animals or the wind through a process called seed dispersal.

Oh, well done team.

Give yourself a pat on the back to that reading.

Okay, so now that we've read and listened to the story of the plant's life cycle I'm now going to show you this table.

I'm going to make it even bigger, so you don't need my face on this one because otherwise the writing will be too small.

Let's read the pink box together.

And I want you to tell your screen which stage of the life cycle of a plant you think that is.

So let's read together the pink box.

One, two, three, the process of a plant, beginning to grow from a seed.

Hmm, the process of a plant beginning to grow from a seed.

This is your clue, tell your screen, which stage do you think that is? Well done, let's see if you were right.

It's germination, well done.

Let's read the top right-hand box in light blue.

One, two, three.

When the stem and leaves have grown and a flower begins to bud.

Hm, when a flower comes from the stem and leaves.

Hmm, I'm thinking, tell your screen, which stage do you think that is? Let's see if you were right.

Flowering.

Well done.

Now let's read the purple box.

One, two, three.

The process of pollen being moved from anther to a stigma.

Hm, when pollen is moved from the anther to the stigma, that's when it's sticky, and I know that's pollen.

Ooh, tell your screen.

Which stage do you think that is? One, two three.

Let's see if you were right.

Well done, pollination.

Let's read the box on the right of that which is in a teal green.

One, two, three.

When pollen travels down to join with an ovule in the ovary.

Ooh, that's the bit when the pollen goes down and it grows and then it turns into a seed.

What's that called again? Tell your screen, one, two, three.

Fertilisation, well done.

Let's see if we're right.

Super, well done, everybody.

I'm going to give myself a yes, because we got that right.

Are you ready? One, two, three, yes.

And bottom left-hand corner in the bright green.

Let's read together, one, two, three.

How seeds are spread away from a plant to be able to grow in a new location.

Ooh, so that's when seeds have to go to a new location in the soil so that they can grow.

What stage is that called though? Oh, what's it called? Tell your screen, it's called seed.

Say it louder, one, two three.

Well done, let's see if you are right.

Seed dispersal, wow team, you are so impressive today, I can't catch you out.

Okay, so this last one has two blanks and then seed.

So it says something plus something equals a seed.

It's like an equation in maths, that's interesting.

Something plus something equals seed.

We've looked at that this lesson, can you remember? What was it? Tell your screen now.

One, two, three, pollen plus ovule equals seed.

Well done, you got that one, right.

I'm going to give you a rainbow cheer, and a rainbow cheer goes like this.

Ah.

Because you are absolutely astounding me this lesson with all of your amazing knowledge of plants.

Can we all do a rainbow cheer on three.

So get your hands out, ready.

You're going to clap and pull out the rainbow.

Are you ready? One, two three.

Ah.

Well done.

Okay, let's keep going.

So team we've looked at the life cycle and then now we're going to look at germinating seeds.

So what do they actually look like when they're germinating? What actually happens down there? Let's take a look.

I hope you enjoyed seeing the stages of the plant growing all the way from a tiny seed into a huge green plant.

So now I have a question for you and I want you to think carefully because you know the answer to this even though I've not told you explicitly this lesson.

My question to you is what three conditions are needed for a seed to grow? Now it's very similar to what plants need, and we've learned about what plants need.

The one thing that a seed needs is the correct temperature but there are two other things.

Using the video that we've just watched, what do you think it needs to grow? Can you tell your screen after you've had a good think.

Well done.

Some of you have had a really good go at that.

Let's see if you are right.

Good, it needs air to breathe and take in the oxygen, and lots of other gases.

And it also needs water.

I wonder, can you tell your screen why do you think a seed doesn't need sunlight but a plant does need sunlight.

Tell your screen now, I'm listening.

Uh huh.

Yeah.

Well done.

Because seeds are in the ground and sunlight cannot get underground into the soil.

So seeds don't need sunlight.

When they grow into a plant, then plants do need sunlight once they are grown outside of the soil and their stems and leaves collect sunlight that turn into photosynthesis.

So a seed is a very special, and really I think quite an amazing thing.

So now that we've looked to germinating seeds, let's look at how seeds are dispersed when they do go and find that soil to grow in.

There are four ways that we're going to look at that how seeds are dispersed.

Let's take a look.

Okay, so in the top left-hand box, you can see that there is lots of very small seeds.

They look white and they're almost a bit like dandelion seeds.

Do you know a dandelion when you blow on it and the seeds are dispersed.

So sometimes the seeds are dispersed by the wind.

Can you say the seeds are dispersed by the wind? Can you give me a bit of a blow of the wind? So seeds are dispersed by the wind.

Well done, okay.

So that's the first way that seeds can be dispersed.

The second way in the top right hand corner.

What can you see in that picture? Can you tell me three things that you can see.

That's one, yeah, what's another thing? And what's one more thing? Well done.

I could see a bird, I could see a big tree, and I could also see some fruit hanging down from the tree.

So sometimes animals like to eat the fruit and then the seeds are in the fruit that the bird would then What would happen Lenny? Do you think I can say that word? Do you think it's okay? So when the bird eats the fruit, it goes into its tummy, and then it does a poo, and in it's poo will be the seeds, which could then drop anywhere, hopefully not on my head.

So that's the second way that seeds are dispersed, they're dispersed by animals.

The third way is if a seed drops down into a river it would then get taken off by the water and it would travel and land wherever it lands, and then hopefully it could grow, if the conditions are right.

The last way is something called explosion.

Can you say explosion, well done? And sometimes plants are very clever and know that they want their seeds to travel, so they explode when their seeds are ready.

So the fourth way is explosion.

Can you say explosion, well done.

So the first way was wind, your turn, wind.

The second way was animals.

Can you pretend to do a poo? The second way was animals whoopsie.

The third way is water, the third way is water, well done.

And the last way is explosion, well done.

You are so good at those actions.

Team I've got a quick quiz for you.

I am going to cover up one of the ways that seeds are dispersed, and I want you to tell your screen as quickly as you can which one you think I've covered up? Okay.

Are you ready? Make sure your eyes are peeled on the screen.

Which one have I covered up now? Well done, it was explosion.

Which one have I covered up now? Ooh, which one was that? Wind, animals, explosion, oh yes, it was water, well done.

Which one have I covered up now? I heard some of you making a funny noise there, was that you? That way was animals with the carrying of fruit through their.

And the last way, which one have I covered up now? The first one that we looked at was? Wind, well done.

Crikey team, we've done a lot of learning today.

I am really, really impressed.

My brain has grown so much.

What do you think, Lenny, do you think they've done well? Lenny thinks you've done very well and he says- really? He says that he's really proud of you for your learning today, so well done.

Let's have a look at our learning review.

Pause the video and answer the questions on the screen to do your recap now.

If you need more time team, pause the video again.

Well done everybody, I am so impressed.

You guys are amazing.

You've grown your brains and you've learnt all about the life cycle of a plant and how seeds are dispersed.

I think that was my favourite action there, or maybe it was the one from the animals.

Team you're excellent, and we'll see you next week for another science lesson all about plants.

Awesome.

Bye everybody.
