Lesson video

Hi, everyone.

My name is Ms. Panchal, and I'm so excited that you've decided to join me on this science lesson today.

So our lesson today is going to be learning about the life cycle of a flowering plant.

And this lesson is part of our bigger unit of learning on what plants do and what they need.

So are you ready to start learning? Let's get going.

So the outcome for our lesson today is I can present the life cycle of a flowering plant.

So we're going to talk through some key words that we're going to use in our lesson today.

So we're going to practise saying them first.

So I'm going to say the word, and I would like you to repeat it back to me.

My turn, life cycle.

Your turn.

Super job.

My turn, germination.

Your turn.

Fantastic job.

My turn, pollination.

Your turn.

Fantastic work, everyone.

My turn, seed formation.

Your turn.

Amazing job.

My turn, seed dispersal.

Your turn.

Wow, everyone, I'm so impressed with your practising of saying these key words.

So I'm going to read the definitions to you now so we can understand what they mean.

So a life cycle is the way in which a living thing changes throughout its life.

Germination is when a plant starts to grow from a seed.

Pollination is when pollen from a male anther is transferred to the female stigma of a flower.

And seed formation happens inside flowers after a plant has been fertilised.

And seed dispersal is the way seeds are spread out from their parent plant.

Now some of you might already be familiar with some of these words, but some of you might not be so sure, but don't worry 'cause we're going to cover all of these words in our lesson today.

So our lesson today is split up into two parts.

We're first going to look at flowering plant life cycles, and then we are going to use that knowledge to look at presenting information about life cycles.

So let's get started with the first part of our lesson today.

So some children are talking about what they have learned about plants and how they reproduce.

Sam says, "Do plants have life cycles like animals do?" Laura says, "I don't think so, plants don't lay eggs or have babies." What do you think? Pause the video here.

Have a little bit of thinking time on your own, and then I want you to share your ideas with your partner.

Do you think plants have life cycles, too, just like animals? What do you think? Excellent ideas, everybody.

Well done, and well done for sharing them with your partner.

So like all other living things, flowering plants also have life cycles.

The first stage in a flowering plant life cycle is germination.

Can you say that for me? Excellent job, everyone.

So germination is when a plant starts to grow from a seed.

Let's do a quick check of our learning.

What is the name for the life cycle stage when the plant first begins to grow from a seed? Is it A, pollination, B, germination, or, C, fertilisation? Have a little think in your head, and then we'll go through the answer.

Fantastic work, everybody.

Well done.

The answer is B, germination.

So that is the first stage of a flowering plant life cycle.

So let's move on.

For a seed to germinate, it needs the right conditions.

Most seeds need water, air, and warmth to germinate.

Let's do a quick check of the learning we've just done.

Which of these things do most seeds need to germinate? A, water, B, air, C, light, D, warmth, or, E, soil? I'm going to give you a little clue now.

There is more than one thing that most seeds need in order to germinate.

If you need to, go back over the last slide to go over the learning before you answer the question.

Click Play when you're ready to continue, and we'll go through the answer.

Great job, everybody.

Well done.

So in order for seeds to germinate, the majority of seeds will need water, air, and warmth.

Super job, everybody.

Well done.

So the next stage in a plant life cycle is growing and flowering.

And during this stage, they grow larger and produce flowers.

Then, the plant may be pollinated.

And this is when pollen from a male anther lands on a female stigma.

And pollination can be carried out by animals or by the wind.

Let's do another check of our learning.

After germination and growing, the next stage in the flowering plant life cycle is.

, when pollen from an anther lands on a stigma.

So what is the missing word? Is it A, fertilisation, B, seed dispersal, or C, pollination? What do you think? Fantastic job.

The answer is C, pollination.

So after germination and growing, the next stage in the flowering plant life cycle is pollination, when pollen from an anther lands on a stigma.

So we've spoken about the first three stages now of a plant life cycle.

So you've got germination, growing, and then pollination.

Super job, everybody, so far.

Well done.

So the next stage of the flowering plant life cycle is fertilisation.

And fertilisation happens when pollen moves from the stigma into the ovary of a flower.

So we can see here that the pollen has moved into the ovary of the flower.

Once the flower has been fertilised, seed formation begins inside the ovary.

So this is where seeds start to form.

Let's do another check of learning.

What is the name for the stage of a flowering plant life cycle when pollen reaches the ovary of a flowering plant? Is it A, fertilisation, B, germination, or C, pollination? Which do you think is correct? A, B or C? Super job, everyone.

The answer is A, fertilisation.

So this is the next stage in our flowering plant life cycle.

Well done, everyone.

So let's do another check of our learning about fertilisation.

After fertilisation, are formed in the ovary of the flower.

Is it A, leaves, B, pollen grains, or C, seeds, or D, nutrients? If you need to, go back to the last few slides and have a look at that diagram to help you answer this question.

So what do we think is the missing word in this sentence? Super job, everyone.

Well done.

The answer is C, seeds.

So after fertilisation has happened, seeds are formed in the ovary of the flower.

Fantastic work, everyone.

So seed dispersal is the next stage in the flowering plant life cycle.

When the seeds are fully formed, they are dispersed away from the parent plant so the new plants won't have to compete with each other for the things that they need.

Seeds can be dispersed by wind, water, animals, or explosion.

So there's lots of different ways that the seeds can be dispersed away from the parent plant.

The seeds that get all of the things they need will then germinate and start the life cycle all over again.

So let's have a look at this diagram here.

We've got a flowering plant life cycle.

We're starting off with germination, and then we move on to growing and flowering and then we have pollination.

After pollination, we have fertilisation.

And after that, that's when the seeds start to form in the ovary of the flower, and then we go onto seed dispersal and then the cycle starts all over again.

But only if the seeds have the things that they need, only then will they germinate.

So we've talked about all of these different stages of a flowering plant life cycle.

I'm so impressed with your work so far, everybody.

Well done.

So let's do a check of our learning.

True or false? Plants disperse their seeds so they will be able to pollinate more plants.

Do we think that's true or false? Fantastic, the answer is false, but I now want you to have a little think about why.

So I'd like you to pause the video here and maybe write down your ideas on a whiteboard.

Why do we think this statement is false? Fantastic work, everybody, well done.

So plants disperse their seeds so that the new plants won't have to compete with each other for water, light, or nutrients.

Well done, everyone.

So let's move on to the first task for today's lesson.

So what I'd like you to do is complete a life cycle diagram showing each of the five stages of the flowering plant life cycle.

So let's just talk through the five stages again.

So stage one is germination, then stage two is growing and flowering, stage three is pollination, stage four is fertilisation and seed formation, which happens in the ovary of the flower, and the final stage is seed dispersal.

So those are the five key stages of a flowering plant.

In your diagram, I'd like you to include the name of each stage as well as a drawing.

So if you need to, go back over the last few slides if you need to go over the learning before you complete the task.

Now if you would like to, you can copy this diagram and use the arrows to help you or you can ask an adult to print it out for you.

Now I'm really looking forward to seeing all of your diagrams. Have a go at this task, and click Play when you're ready to continue.

And we'll go through an example answer.

Off you go.

Brilliant work, everybody.

Well done.

I'm so impressed with all of your diagrams. So maybe your diagram looked a little bit like this.

So we can see we've got germination, then we're moving onto growing and flowering where we can see the leaves and some of the petals and flowers.

Then we've got pollination, we're moving onto fertilisation and seed formation.

And this is where the seeds are formed in the ovary.

And then we move on to seed dispersal.

And if the seeds have the right conditions, they will then start the whole cycle again.

Well done, everybody.

I'm so impressed with your work.

Was your diagram similar to this or was a little bit different? Well done for having a good go.

So we've learned about the flowering plant life cycles, and we're now going to think about presenting information about life cycles.

So Alex wants to share what he has been learning about flowering plant life cycles with his little sister's class who have been learning about animal life cycles.

Alex says, "I'm not sure she'll understand a life cycle diagram like the one I've drawn." How else could Alex present the information he has learned? So pause the video and have a little think.

Alex would like to share his learning about life cycles, but he think that his little sister might not understand the life cycle diagram.

So how else could Alex share his learning? Excellent ideas, everybody, well done.

So we can present information about life cycles in lots of different ways.

So Alex could present his information in a written form, such as a poster, a comic strip, or an information text.

He could also present his information orally, that means in speaking, with spoken language, for example, in a podcast, video or oral presentation.

So there's lots of different ways that Alex could present his learning.

It could be that he does it with writing or he could talk about his learning.

Let's do a quick check of our learning.

Alex could present his information about flowering plant life cycles in a written or form.

What do we think is the missing word? Super job.

The answer is oral.

So he said that he could do some writing about his learning to show his sister, or he could also talk about his learning.

Alex says, "My little sister is younger than me.

How can I present my information in a way that will make it easier for her to understand?" What do you think? So pause the video here, have a think on your own in your head, and then I want you to share your idea with your partner.

How can Alex present his information in a way that it's easy for his little sister to understand? Have a think on your own.

Share your ideas with your partner.

Great ideas, everybody.

Well done.

So Jacob says, "You should make sure that any technical words, like pollination, are clearly explained." Izzy says, "You should include photographs or drawings of plants in your local area so she can see how plant life cycles are taking place around her." Alex says, "Do you have any other ideas?" So what were the ideas that you shared with your partner, whether the same as Jacob and Izzy's, or whether a little bit different? Well done for thinking of some different ideas of ways that Alex can present his learning.

So let's do a check of our learning.

Alex's information about life cycles should be presented, A, clearly so it's easy to understand, B, in a complicated way so people know he's very clever, or C, with no pictures so he doesn't have to do any drawings.

So which do you think is the correct answer? A, B or C? Super work, everybody, well done.

The answer is A.

So Alex's information about life cycles should be presented clearly so it's easy to understand, because we have to remember his sister is a lot younger than him.

So let's move on to the next task for this lesson.

So I would like you to create a presentation sharing all of the information you have learned about flowering plant life cycles.

Your presentation can be in written or oral form.

So you have creative freedom here as to how you would like to share your learning.

We've done lots of learning today on flowering plant life cycles and the different stages.

So I want you to choose a way to present that information.

Now, you can do a poster, you could do an information text, or maybe you could record yourself doing a little video explaining your learning.

Or you could actually be involved in a podcast, too.

Maybe you can film you and your partner having a conversation about flowering plant life cycles.

So pause the video here, have a go at creating your own presentation.

I'm really looking forward to seeing all of your amazing work.

Off you go.

Brilliant work, everyone.

Well done.

I'm so impressed with all of your presentations.

So Alex says, "I made a video clip where I explained each part of the life cycle with a diagram." Jacob says, "I created a poster showing the life cycle with some extra notes explaining each step.

Izzy says, "How did you present your information?" Did you do something similar to Alex or Jacob or did you do something different? Well, I can see that you've worked really, really hard with your presentations, and I'm so impressed with your work.

Super job, everyone.

Well done.

So we've come towards the end of our lesson today.

So let's do a recap of our learning.

Germination is when the seed first starts to grow into a plant.

To do this, it needs water, air, and a warmth.

So those seeds need those three essential things.

And if they don't have those things, then germination will not happen.

The life cycle of a flowering plant includes five different stages.

So first stage is germination, then we move on to growing, and the third stage is pollination.

And then the fourth stage is where fertilisation happens and seeds form, and the seeds form in the ovary of the flower.

And finally, we then have seed dispersal.

So this is the life cycle of a flowering plant.

So next time you see a flower maybe in your garden or maybe on a walk, you can maybe think about what stage of the life cycle is it at.

I'm so impressed with all of your work today, everybody.

You've produced some fantastic work.

Have a great rest of the day, and I'm sure I'll see you very soon in the next science lesson.

Bye-bye.
