Lesson video

Hi, everyone.

Welcome to today's science lesson.

I'm Miss Harris.

What's your name? It's lovely to meet you.

Now, today, we are going to be doing our last lesson of our plants unit.

I'm really sad about that.

We are going to be looking at what changes have occurred to our bean plants.

Now, we planted a kidney bean in lesson one.

And over the last few weeks, we've been watching it change and grow.

If you don't have a bean plant in this lesson, don't worry, because you can use my bean plant to help you throughout the lesson.

And I'm going to be asking you to do other activities just in case you don't have a bean plant.

Okay? Great.

So let's see what else we're going to be doing.

So we are going to be drawing a picture of our bean plant or Miss Harris's bean plant.

We're going to be measuring our bean plants, looking at the stages of growth, observing the changes to our plants.

And then we've got our end-of-lesson quiz.

Now, each lesson I've been asking you to identify what plant is in my background.

So take a good look, because I'm going to ask you at the end to tell me the name of it if you know it.

Or if not, I will tell you what it's called.

So take a good look.

Great.

Now, for today's lesson, you will need an exercise book or a piece of paper, a pencil, a ruler, and your brain.

If you need to get any of these things, you can pause the video and go and get them now.

Great.

Now we can get started.

So a scientist is a person who studies the world around us, including the living things and non-living things.

So we are looking at plants, which are living things.

Let's do our Star Words.

These are the important words we're going to be using in today's lesson.

So let's say them.

Ready? Stem.

Good.

Roots.

Can you do that? Germination.

Growth.

Well done.

Needs.

Survive.

Grow.

Stem.

Roots.

And this one's not on there, but let's do it anyway.

Leaves.

Good.

Well done.

So here's a picture of my bean plant.

If you have a bean plant, I would like you to go and get it now.

And I would like you to draw a picture of it.

Otherwise, you can draw a picture of my bean plant here.

Because over time it has changed a lot.

And in today's lesson, we're going to be looking at what changes have occurred since I planted my seed.

So pause the video and do that now.

Great job.

Well done.

So when a seed is sown, when it's planted into wet soil, it begins to grow.

And this is called germination.

Now, we've been learning about how lots of plants and trees have roots which grow under the ground.

So in this picture, we can see what is happening on top of the soil.

So we can see the plant has pushed its way out of the soil and has grown lots of leaves and a lovely long stem.

But underneath the soil, we know that there are lots of tiny roots, which are soaking up all the nutrients from the soil.

So I just thought I'd put this picture in here just to show you that we can't always see the roots in our plant.

But if you put your seed into a glass jar, you'll be able to see the roots grow.

So let's get started with measuring our bean plant.

So if you don't have a bean plant, don't worry, I'm going to give you something else to do in a moment.

So using your ruler, I would like you to measure how tall your bean plant is.

So you can see here, I've put my ruler, I've put the zero on top of the soil.

And I measuring from the soil to when the plant finishes.

So you can see it puts a red line there, and that's the number that I will read on my ruler.

Now, if you don't have a bean plant, I would like you to measure the length of your pencil or the length of a plant in your home.

I'm going to show you now how to measure your ruler.

Sorry, how to measure your pencil with a ruler or how to measure another plant.

So I'm going to show you how to do it.

If you're unsure, you can carry on watching, or you can get started with measuring the height of your plant.

Pause the video and do that.

So here I have got an orchid plant.

So I am going to be measuring the height of my plant and showing you how to do it.

So I got my ruler here.

And you can see it goes from 0 to 15.

I'm going to put my ruler into the soil like so and push it down a little bit just so it's in line with the bottom of the plant.

I then going to read the numbers.

I'm going to bend down, and I'm going to look at where the stem stops and the leaves begin.

I can see that it's at about 4 1/2 centimetres.

Yours might be something different.

So I can write that my plant is 4 1/2 centimetres tall.

And to measure my pencil, you can see I've put my pencil at the start of the zero, in line with zero.

The pencil's just a little bit more than 15.

So what I'm going to do is I'm going to put my finger roughly where 15 is, because it doesn't need to be perfect, and then I'm going to move it in line so I can see, I'm going to count on 15, 16, 17.

So my pencil is 17 centimetres long.

Okay, so now let's look at the different stages of growth that your plant will go through since you've planted as a seed.

So here, we can see that we've put the seed in the soil just below the soil, not really far down.

Not too deep into the soil, otherwise it won't grow properly.

So we've got it just right.

And it's got a nice, kind of a brown-colored jacket, what we call a coat around the seed to protect it before it grows.

So that's step one, is the seed.

Step two, we can see that some roots have begun to grow at the bottom of the plant, which have grown down into the soil.

So that's step two.

Then step three, the seed limb begins to grow, and we can see the stem has pushed its way out of the soil.

So the seedling has begun to grow properly.

And then we've got step four, which is where we can see that leaves have now grown on our plants.

So we can see at the other side, we've got two there with lots of lovely leaves on them.

So let's go back.

We've got step one, is planting the seeds.

Step one is seed.

Step two is roots.

What's step two? Good.

Roots.

Step three, we've got the seedling pushing its way out of the ground.

And you can see that the little brown coat that it was wearing, it's slowly pushing its way out of it.

And then step four, we have got leaves.

So keep those in your head, because in a moment, I'm going to ask you to draw a picture of each step and to write what each step is.

Are you ready? So I would like you to write what are the stages of a plant.

You can use this word map here to help you with your spelling.

So step one, step two, step three, and step four, I'd like you to write and draw a picture to go with each stage.

Pause the video and do that now.

Well done.

So let's check what stages there are.

So we've got step one, which is a seed.

Step two, grow some roots.

Step three, the seeding has now pushed its way out of the soil.

And step four, we have got lots of lovely leaves.

I want you to have a think now.

What stage is your plant in, if you've got one in front of you? If you haven't, I would like you to look at my plant here.

And I would like you to think, what stage is my plant in? So what stage is Miss Harris's plant in, or what stage is your plant in? Pause the video and have a real close look now.

Well done.

So my bean plant I can see is in step four because it's got lots of leaves which have grown around the stem at the top.

Now let's look even closer at the changes to our bean plants.

So we know the over time, our plants have changed a lot, from just a small seed in the ground growing into a wonderful, bright green plant.

So I would like you to write a sentence about what has changed since you've planted your seed.

Now, if you don't have your bean plant, you can have a look at my bean plant here.

So what has happened to Miss Harris has bean plant since I planted it as a seed? So remember, it first looked like this.

It was just a tiny seed in the ground here.

And now it looks like this.

So pause the video and write a sentence about the changes that have occurred to your bean plant or my bean plant.

Well done.

So your sentence might have been, "My bean plant has grown lots of roots, "and it has grown a really tall stem." You might have said that, "My bean plant has grown two leaves." Maybe you've got two or more leaves on them.

Well done.

It's now time for our end-of-lesson quiz where you can show off all the knowledge you have learned today about bean plants and their stages of growth.

But before we go, can you tell me what plant is in my background? Do you know what it is? So this is called a fern plant.

What's it called? So a fern plant is a wild plant, which you might see lots of if you go to a forest.

Or lots of parks might have lots of groups of ferns because they grow so quickly and in real large amounts.

So there'll be lots of them if they are growing.

And they spread really quickly.

Now we're at the end of our unit.

If you would like to share your work that you have completed over the last few weeks, or to send us a picture of your wonderful bean plants or tomato plants, you can ask your parent or carer to share a picture of your work on Instagram, Facebook, Twitter using the tag #OakNational and the hashtag #LearningwithOak.

We would love to see all of your wonderful work.

But remember, it must be your parent or carer that shares it for you.

Have a great rest of your day.

And I've really enjoyed teaching you this unit.

See you soon.
