Hello and welcome to today's lesson from the unit, growing plants.

This lesson is called plants from seeds.

Hi, my name is Mrs. Waller and I'm going to be helping you to learn more about plants.

In this lesson today, you will be able to explain that most plants produce seeds which grow into new plants.

So let's start by taking a look at our keywords for today's lesson.

Plant, seed, hand lens, root, and shoot.

Take a moment to think.

Have you heard of some of these words before? Do you know what some of these words mean already? Well, don't worry if you don't know them because we are going to be using these words all the way through the lesson today.

This lesson is in three parts.

The first part we'll be thinking about where do plants come from? And in the second part of the lesson we'll be looking more closely at seeds and thinking about, do all seeds look the same? In the third and final part of the lesson, we'll be learning about how do seeds start to grow.

Are you ready? There are lots of different types of plants.

Take a look at this photograph here and you can see different types of plants in the park.

You might be somewhere where you can look out of a window and you might be able to see different types of plants outside.

Do you know where plants come from? Most, but not all plants grow from seeds.

Inside of a seed is everything it needs to help it to begin to grow.

And we can see a photograph of a tiny seed here with a plant just starting to grow out of it.

So if we know that plants come from seeds where does seeds come from? Each type of plant makes its own type of seed and it's the seed that grows into a new plant.

It's very clever, isn't it? Let's take a look at some examples.

We've got some tiny black poppy seeds here, and you might recognise this one.

You might have collected conkers before.

So that those are seeds from the horse chestnut tree.

And we also have these pea seeds that have grown inside of the pea pod.

Lots of different types of seeds all produced by different types of plants.

Let's take a look at the poppy seeds again.

Plants with flowers such as poppies grow from their seeds.

So you can see those tiny little black poppy seeds have been produced by the poppy, and then they've grown into these beautiful red poppies growing in the field.

Let's take another look at our horse chestnut seeds are conkers and it's incredible to believe, isn't it? That that enormous tree once grew from a seed, from the horse chestnut tree and it's now grown into a brand new plant which is this fully grown horse chestnut tree.

And now it's time for me to check your understanding of the lessons so far.

Where do plants come from? People put plants in the ground.

The soil makes new plants or seeds grow into plants.

Take a moment, have a think about it.

And which one are you choosing? Yes, it's C, seeds grow into plants.

Our next question is a true or false question.

All seeds come from shops and factories.

Do you think that's true or do you think that's false? Yes, it's false but can you explain why do you think it's false? So I think this because and how would you finish with your own explanation? You might want to choose from one of these.

I think it's false because you cannot buy seeds in shops or sometimes seeds made by plants are sold in shops.

Which one do you think? Yes, that's right, it's B.

Sometimes the seeds that are made by plants are sold in shops.

So sometimes you can buy seeds from places like garden centres and supermarkets.

Which statement below is false? Plants with flowers can grow from seeds, fruit and vegetables can grow from seeds.

Trees can grow from seeds or all plants grow from seeds.

Which one do you think is false? Yes, that's right.

Most plants grow from seeds, but not all plants.

And if we think about the examples that we've looked at so far we've looked at plants with flowers, so that's the poppy.

And also we've looked at the horse chestnut tree and all of these examples are plants that grow from seeds.

Onto your practise tasks now.

Jun and his brother scoop out a pumpkin to make soup.

Jun is surprised to see seeds inside.

So if you look at the photograph there of the pumpkin that's been carefully cut in half you can see the seeds that were inside of the pumpkin.

Now Jun's brother says, "Plant the seeds to grow a pumpkin for next year." But Jun says, "You can only buy a pumpkin from a shop." Who do you agree with and why? Let's take a look at the answer.

It's Jun's brother that is right because you can grow a pumpkin from its seeds.

And Jun's brother is saying a pumpkin is a plant that produces seeds that can grow into a new pumpkin.

Is that the same as what you were thinking? Maybe you could give that a try for yourself.

Moving on to the second part of today's lesson where we're going to be thinking about do all seeds look the same? Different types of seeds can look and feel very different to each other.

So if we take a look at some examples, we've got some seeds here from a sunflower.

We've got some mustard plant seeds, and some seeds from a fruit called a pomegranate.

Now look really carefully.

They definitely don't look the same, do they? Are you sure that these are all examples of seeds? I would like you to think of some describing words.

So what words would you use to describe these different types of seeds? Some seeds are large.

Now look at this.

You'll never believe it.

These seeds are from the cocoa de mer tree and they are the largest and the heaviest seeds in the world.

And something else that you might not think is a seed but a coconut is a large seed and it grows on the coconut palm tree.

So what about small seeds? Well, we know that seeds can be small too.

These poppy seeds are less than one millimetre in length.

And again, look at the photograph and they look like tiny little dots, don't they? Little black dots from the poppy plant.

Do you think this is the smallest seed? Of course not.

No, there are seeds from a flower called an orchid and they're the smallest seeds in the world.

If you take a a look at the photograph on the person's hand you can see what looks like tiny, tiny specs.

And the seeds from the orchid are the size of dust.

I'm going to check your understanding of this part of the lesson now.

All seeds are the same size, true or false? Yes, it's definitely false.

Now can you explain why do you think this? I think this is false because.

You might want to choose one of these statements.

Different types of seeds can be different sizes or different types of seeds are the same size.

Yes, we know it's a don't we? Different types of seeds can be different sizes.

We've been learning about the cocoa de mer and the coconut really large seeds from the tiniest poppy or orchid seeds and all the different seeds that are different sizes in between, well done.

Our next question, Aisha and Andeep have have sorted some seeds into two groups.

They've sorted their seeds into big seeds and little seeds.

Now who do you agree with and why? Aisha's saying, "The only thing that can be different about seeds is their size." But Andeep is saying, "No seeds can be different in other ways." Would you agree with and why? That's right, it's Andeep.

It's not just that seeds can be big and seeds can be small.

There are other ways that seeds can be different.

It might be their colour or it might be their shape.

And there's lots of other things that make seeds different to each other.

Now I'd like you to have a look at some seeds really closely.

And don't worry if you haven't got any seeds you can buy mixed bags of seeds or you could go out yourself on a seed hunt and collect some seeds.

And when you are observing the seeds if you've got a hand lens, that would be brilliant that would help you to look at them more closely.

But don't worry if you don't have a hand lens just look really carefully with your eyes.

And you might want to use other senses too.

You might want to feel what do the seeds feel like? And talk to a partner about how the seeds are the same and how they are different.

You might want to use these sentence status and you might pick up some seeds and say these seeds are the same because.

Or you might show a couple of different seeds and say these seeds are different because.

Pause the video and go and observe some seeds.

Now let's have a look at some ideas.

My seeds are the same shape, so you might have observed lots of different types of seeds that are maybe oval shape all the same shape together.

My seeds are different sizes.

Yes, so you might have observed big seeds, medium seeds and small seeds.

My seeds have different patterns on them.

That's right, isn't it? So you might have looked at the patterns on the seeds.

So you might have noticed the stripy sunflower seeds and you might have looked for different patterns on different types of seeds.

Or did you observe anything else? Now it's time for you to sort the seeds into different groups.

So we've been observing them so far and now you might want to decide on shape or colour or something else.

And you might want to sort your groups using two sorting circles.

And you could put all the seeds that are one type of thing.

So maybe we could have these seeds are stripy all in one circle and these seeds are plain all in another circle.

So think about your observations and think about how you might sort your seeds into different groups.

Pause the video again and have a go now at sorting and grouping.

Let's have a look at some ideas.

I grouped my seeds into light and dark colours.

That's a good idea, isn't it? So all the light seeds in one sorting circle and all the dark seeds in another.

I did stripy seeds and plain seeds.

Oh yes, I wonder if the stripy sunflower seeds were in that group.

I grouped my seeds into big and small seeds.

Yes, that's quite a common one to do, isn't it? Putting them in their groups according to their size.

Or again, did you have another idea? So take some time to talk to somebody else and share how did you group and soar to your seeds today? We're moving on to the final part of today's lesson now and we're going to be learning about how do seeds start to grow.

When a seed has everything it needs, it's amazing.

A new plant begins to grow out of the seed.

Let's take a look at these incredible photographs.

If you look really closely, you can see these orangy brown coloured little seeds and you can see the new plant starting to grow outta the seed.

And again, if we look at this photograph we can just see these green shoots starting to grow up outta seeds.

Take a look at this photograph now.

Do you know what is happening here? Yes, we've got the roots that are growing downwards outta the seeds growing down for water.

These are the roots of the new plant.

And then we also have a shoot that's growing up towards sunlight.

And this is what we call the shoot of the new plant.

Are these the same ideas as what you thought was happening? I'm going to ask you a few more questions now.

So take a look at this image and what is the arrow pointing to? Is it the root, shoot or seed? Yes, well done.

It's B.

It's the shoot growing upwards outta the seed.

And what about this arrow now? Is it pointing to the root shoot or seed? Well done.

Yes, this is the root and it's growing down outta the seed towards water.

Fantastic.

If you've ever planted seeds before you will know that seeds take time to grow.

It's not just something that happens overnight but we can plant them and we can observe what is happening over a number of weeks.

Do you know how to plant seeds? Talk to somebody else and tell them what did you do or what do you think that you might need to do? Well, I've been out into the garden and I've recorded a video of me planting seeds.

So watch the video so that you'll know what to do when you are planting seeds.

Hello again, I've come out into the garden and I'm going to plant some seeds.

Have you ever planted seeds before? I'm going to be planting these broad bean seeds and the first thing that I'm going to do is I can either use a small garden trowel or if you haven't got one of those, you can use a spoon.

And we are going to fill our pot with soil.

There we go.

Soil in the pot.

Number one, done.

What are we going to do next? So I'm going to take my broad bean seeds and I'm going to push them down into the soil.

Take this one, push it down into the soil, and this one.

Make sure they're really pushed down.

And then I'm going to cover those over with a little bit more soil.

There we go.

Fantastic.

And the last thing that I'm going to do is I can either use a water spray or I can take a watering can and I'm going to give my seeds a little bit of water and I'm going to put the plant pot somewhere warm and sunny over to you, let's get planting.

And now it's time for you to have a go.

Plant some fast growing seeds.

If you remember the ones that I planted were broad bean seeds and get ready to watch them grow into plants over the next few weeks.

Do you remember what to do? So first of all, get a pot and fill it with soil.

Next, push your seeds into the soil.

After that, cover the seeds with some more soil.

And what did we do right at the end? Do you remember? Yes, finally, add some water and put your pot in a sunny place.

Pause the video and plant your seeds.

Remember that today's lesson is for you to know that plants produce seeds which grow into new plants.

So once we've planted our seeds, I really want you to observe the plants growing over a number of weeks.

It would be brilliant if you could record your plant observations today and next week and the week after and keep going and keep going, maybe even up to six weeks or even longer than that so that we could observe plants growing from seeds over an amount of time.

So here's the chart that I've produced and we've got a little plant pot in each box on the chart.

And it would be great if you could draw a picture of anything that's grown today, in the first plant pot on the chart.

Has anything grown today? Take a good look inside of your plant pot and see if you can draw what you can see today.

Now this final task is to make sure that you know and understand and can remember how to plant seeds.

So I've put those little diagrams next to one, two, three, and four.

And let's see if you can write your own instructions explaining what to do and how to plant seeds maybe for somebody else to follow.

We've come to the end of this lesson now.

So let's think about what we've learned today.

We know that most plants produce seeds which grow into new plants.

Can you think of anything else that you've learned? Yes, that's right.

Different types of plants can grow from different types of seeds.

Anything else? How about what happens when a seed starts to grow into a plant? Yes, do you remember? The root grows down and the shoot grows up, well done.

That's the end of today's lesson.

Have a go at the exit quiz and remember to think like a scientist.

Good luck and I look forward to our lesson next time.
