Hello there, my name is Mr. Wilshire, and in this lesson, we'll be looking at the circulatory system.

We are looking at the do and review stage.

The outcome for this lesson is: I can use a plan to present information about the circulatory system in humans to other people.

There are some keywords to consider as we work our way through this lesson.

The first is circulatory system.

Then, it's present.

After that, verbal.

Then, pictorial.

And finally, model.

Don't worry if you're not too sure what some of these words mean.

As we go through the lesson, as the words are used, the meanings should become clear, but don't worry, the definitions are also on the screen for you to have a read through now.

So if you need to, pause the video now and continue when you are ready.

The first part of this lesson is called presenting scientific information.

Lucas wants to explain to his friends how the human circulatory system works.

Here's Lucas, and he's obviously got an idea.

He says, "I've made a draught plan of what information to include when I explain how the heart, blood, and blood vessels work together in the human circulatory system." Excellent.

A plan is a good place to start, putting all of your ideas down onto paper and organising it in some way.

What does Lucas mean by a draught plan? Discuss.

What does Lucas mean by a draught plan? What does the word draught mean? We know that a plan is putting ideas down onto a bit of paper.

Let's find out more.

Well, writing a draught plan will give you an opportunity to find ways of improving your work.

He says, "I've created a flowchart that shows the steps of the circulatory system from beginning to end.

This has helped me to get my ideas in order." Excellent.

He's got all of his ideas in the correct order then, hasn't he? It's a draught because he can go back to it later and make some changes if he needs to.

He doesn't need to stick to this plan exactly.

He can change things as he goes along, as long as he records down what exactly he's changing.

Lucas is thinking about how he might present the information that he finds to his friends.

He said, "Well, the flowchart has helped me to plan the information.

Now I must present the circulatory system in a suitable way so that my friends find it informative and interesting." Hmm, that's very true.

You can't just stand up and read out a bullet point list, can you? If you're presenting something, you need to make it interesting.

You can't just keep showing the same slide over and over again.

Do you have any ideas on how Lucas could present the information then? Have a quick discussion, and restart the video when you've done that.

What ideas did you have? I don't know if Lucas is going to be able to do any juggling with this presentation.

I don't really think that would make any sense, so I wonder how else he can make it interesting and make it stand out.

Let's stop and think.

Which of these are important when presenting scientific information? Should it be interesting? Should it be informative? Should it be funny? Or should it be suitable for the audience? The answers here are A, B, and D.

All of those things are very important when presenting scientific information.

Doesn't really need to be funny to get the point across.

Scientific information can be presented in different ways.

Scientists often share their work by giving talks or speeches at different conferences.

These are verbal presentations.

Here you can see someone presenting verbally, and it's up to the people who are in the audience to listen to what is going on.

Juggling certainly wouldn't make any sense here, would it? Aisha says, "You could give a speech about the circulatory system and then finish with some verbal questions and answers." Scientists also present information using pictures.

Pictorial presentations include diagrams and photographs.

Here you can see an example of somebody presenting pictorially.

They've got a map of the stars there and they're drawing different items onto a piece of paper.

Andeep says, "You could draw a diagram to show what's happening inside the human body to explain the circulatory system." That's a good idea.

Just like you might have done in previous lessons, you may have drawn some pictures or diagrams or maybe filled in the blanks of missing words.

Those are always really good ideas to keep people interested in the lesson that's happening in front of them.

Scientists will also present information using writing.

This often includes reports about research that they've carried out.

Some scientists will even write newspaper and magazine articles.

They'll even write whole books about science.

Here you can see an example of someone presenting some work in writing.

There's a small diagram to go alongside the writing there.

It looks like there's lots of words inside this book.

My goodness.

Laura says, "You could write a chronological report about the circulatory system." That's a good idea as well.

You could find what you think is the very start of the circulatory system and then work your way around the different points until you come back to the beginning.

The scientists who write newspaper and magazine articles about their work sometimes need to shorten their words down to make sure it all fits down on the page, so there's lots of things to consider when you are sharing work in this way.

Let's stop and think.

Scientific information must be presented in a written report.

Is that true or false? The correct answer here is false.

I wonder if we can justify our answer here.

Have a little look at the two statements that are written down.

Decide which one best answers this question.

The correct way to justify our answer here is A, scientific information could be explained in verbal, pictorial, and written presentations.

Remember, it can be explained in this way.

It doesn't mean it has to be.

It's up to you as the author to decide how you're going to present that information and make it interesting.

Here is task A.

You are going to need to use your flowchart plan or the one that Lucas made on the next few slides as an example.

You can use them to prepare your final report in a verbal, pictorial, or written presentation.

When you are ready, present the information to a group of family or friends.

Here is the plan that's made by Lucas.

You can use this as an example to help you understand the processes that go on throughout the circulatory system.

For example, the heart pumping blood to the lungs to collect oxygen, or blood delivering oxygen and nutrients to the body, or maybe that the heart pumps blood low in oxygen back to the lungs.

There's also a second slide here too, which shows how the lungs absorb carbon dioxide to be exhaled.

If you think that there are any parts missing to these slides, you can add them in, but the important part here is to come up with your plan so that you are ready to present.

Best of luck with your task.

Restart the video when you've done that.

How did you get on? Your task was to use a flowchart plan to prepare your final report in a verbal, pictorial, or written presentation.

Here you can see some examples.

"I made a slide deck about the circulatory system.

I included pictorial and written information, and then I presented it verbally." This person said, "I wrote a story about blood travelling through the circulatory system.

I gave it to my friends to read for themselves." That's a good idea.

You could also turn this story into a comic book too, just to make it really jump off the page.

I wonder how you chose to present your information.

What ideas did you come up with? Are you going to write a story? You're gonna make your own slide deck? Maybe you could use a computer to research some different images or maybe even some GIFs and videos that are gonna show off the things that you know.

Let's move on to the next task now to think about how we could use a model to help us to display this information as well.

The second part of this lesson is called using models.

Izzy uses a model to explain the circulatory system to her friends.

Here is Izzy.

Now, models are used to present scientific information that can't be experienced directly.

For example, something that's underneath your skin.

Izzy says, "A model can be a pictorial form of scientific information.

Models can also be explained verbally." Izzy uses chalk to draw a large outline of the human body on the ground outside.

Here you can see a body outline with some chalk.

Next, she draws the heart and the lungs in the correct position in the human body.

And finally, she adds the small intestine for her model.

Remember, a model doesn't need to be something that's been 3D printed.

A model can be something that's drawn down in a large way as well.

Izzy then asks her friends to follow her verbal instructions and move around the model she's made.

Her friends are going to be the blood.

They're going to be learning more about the circulatory system as they go.

It certainly is a different way to present some information to make it live action.

Izzy then says, "Well, I will read from Lucas's flowchart to make sure that I include all the important scientific information and in the correct order." What a very good idea, using someone else's work, magpieing it to make it a bit of your own.

So she says, the start, the heart pumps blood to the lungs to collect oxygen.

"To be part of the circulatory system model, my friends will start at the heart.

Okay, just around here.

They're gonna move to the lungs, just behind.

As part of the model, they'll pick up a red beanbag or a token from the lungs to represent blood collecting oxygen." What do you think here? What would Izzy's friends do next? They've got pumped from the heart to the lungs.

They collected oxygen.

Now what? Discuss.

Can you remember what happens next? Well, hopefully you said something along the lines of this: blood rich in oxygen is returned to the heart to be pumped all around the body.

When blood passes the intestines, it picks up nutrients that have been absorbed from food.

She says, "Next, my friends will move back to the heart and then out to different parts of the body of the model.

As they pass through the small intestine, they will pick up a yellow bean bag or token to represent blood collecting nutrients from digested food." Of course, yes, the blood doesn't just transport oxygen, does it? It also needs to pick up nutrients to take that to the different parts of the body as well.

But what are Izzy's friends going to do now? They've got oxygen, they've got nutrients.

What's next? Discuss and decide.

So what are our friends going to do now? You could have said something along these lines.

Blood delivers oxygen and nutrients to the body, and it picks up waste products including carbon dioxide.

Veins take blood low in oxygen back to the heart, and the heart pumps blood low in oxygen back to the lungs where it's gonna fill up with oxygen again.

Izzy says, "Next, my friends will deliver the oxygen and nutrients to a part of the body.

In exchange, they'll pick up a blue bean bag or token to represent carbon dioxide.

They'll then move back to the heart and back to the lungs to deliver the waste carbon dioxide and start the cycle again." That's another thing to remember as well, isn't it? As well as collecting oxygen and nutrients, when the nutrients and the oxygen have been depleted, the blood will take on carbon dioxide and it needs to return to the heart to be pumped back to the lungs to expel the carbon dioxide by breathing out, and when that person breathes in, he's gonna replenish the blood with oxygen again.

Let's stop and think.

Why are models often used to present scientific information? Is it because they're fun to build? Is it because it helps us to visualise things that we can't experience? Or is it because it helps us to set up investigations and record results? Discuss these statements and decide on the answer.

Well done.

The answer here is B, models help us to visualise things that we can't experience directly.

So here is task B.

You are going to use a human body model to present how blood travels through the circulatory system.

Ask a partner to draw around your body on a roll of paper, or you could do this in the playground if there's lots of room.

You can then draw where the heart, the lungs, and the small intestine would be.

That's a very good point.

Filling in the body outline with lots of information.

Use one finger then to trace the journey of blood from the heart to the lungs, and then back to the heart again before travelling out to a chosen body part.

Remember to pass the small intestine on the way as well, because you need to collect nutrients from there.

For the return journey, trace your finger from the body part back to the heart to be pumped to the lungs to be exhaled.

Be ready to go back to the heart to start the journey all over again.

Remember, the circulatory system runs in a bit of a circle, doesn't it? Although it does have different branches going off to different parts of the body doing things.

So you could try and represent this in your big model as well.

Well, the best of luck to you with creating your models.

Restart the video when you've done that.

So here are some answers that you could have had.

It says, use a human body model to represent how blood travels through the circulatory system.

Andeep says, "I kept my finger moving around the body model from the heart, to the lungs, back to the heart, oh, and past the small intestine.

I explained to my friend that I was delivering oxygen and nutrients to the body." Laura says, "When I traced my finger back to the heart and to the lungs, I was transporting carbon dioxide to be exhaled as waste gas." Good memory, guys.

Well done.

There's lots of different ways that you could present different information.

You could create a story.

You can do your own comic strip.

You can write it down in bullet points or even say it all verbally.

In this way, using a model, you are able to give people a visual insight.

There are lots of different ways that people learn.

So learning visually like this might help a few people remember the different steps that take place for oxygen and blood and nutrients to travel around the body.

Well done.

Let's summarise our lesson.

Scientific information should be presented in an informative and interesting way suitable for the audience.

The circulatory system can be explained in verbal, pictorial, and written presentations.

Models can be used to present scientific information that cannot be experienced directly.

So there are lots of different ways that we can show off the things that we know.

If we've done ourselves a draught plan, it doesn't mean that we have to stick to it.

We can go off the tangent a little bit and come up with some other ideas to make it even better.

If you are having a go creating your own model, remember, you don't have to build anything for it to be a model.

You could do a flat version and use people as the things that move around, just like the children did in the example.

Well done for completing your tasks in this lesson.

I've been Mr. Wilshire.

Thank you very much for listening.
