Lesson video

Hello, everybody.

Welcome to Computing.

My name is Mrs. Franzsen.

It's really good to see you here.

We've got lots of really good learning in store today, all about our computing topic.

Are you ready? Then let's get started.

By the end of today's lesson, you will be able to compare painting on a computer and painting on paper, and explain which one you prefer to use.

Let's go through our keywords today.

We're gonna do these in the style of my turn and your turn.

So I am going to say the keyword, then I want you to say the keyword, and then I want you to listen really carefully as I explain the meaning of that keyword.

You ready? Here we go.

First word, my turn, computer.

Your turn.

Excellent.

A computer is a machine with programmes that follows commands.

Next word, my turn, commands.

Your turn.

Great.

A command is an instruction used to control something, and we're going to be using those keywords, computer and command, in our lesson today.

So listen out for them.

Right, in the first part of today's lesson, we are going to be comparing digital painting to painting on paper.

Let's go.

What is the last artwork that you made on paper? Hmm, have a think about that.

It might be very recently.

When did you draw on paper? When did you paint on paper? How about using some crayons on paper? Have a think about when the last time was that you made art on paper.

We can create artwork on paper.

We can also create artwork using computers.

Did you hear that keyword there? Computers.

Now, what was a computer? See if you can remember.

A computer is a machine with programmes that follow commands.

There are some similarities and some differences.

Have a look at my two examples at the bottom.

I've got a drawing on paper, and I've got an artwork that was made using a computer.

When we paint on paper, we use tools like pencils, crayons, and paint, and we make marks directly on the paper.

Can you see in the photograph, the boy is painting on the paper using paints.

When we paint using a computer, we use a mouse or our finger to select choices in a programme, and the programme can show our choices on the screen.

At the bottom here, I've got an image of my painting programme where I drew a flower using the painting tools.

If you make a mistake on a computer, how do you fix it? Pause the video and have a little think about that question.

I'm gonna ask it again.

If you make a mistake on a computer, how do you fix it? Welcome back.

Well done for having that little think.

You use the undo tool.

The undo tool will fix your mistake, and at the bottom here, we've got a symbol of the undo tool.

You can see it in lots of different programmes, and in painting programmes, you can use the undo tool to go back one step to fix your mistake.

How could you fix a mistake on paper? Look at the photograph here.

We've got some people creating artwork using paint, and on the brown paper, we can see lots of splodges of different colours of paint.

If you made a mistake on paper, how could you fix it? You can pause the video now to have a little think about ways you could fix a mistake on paper.

Welcome back.

Well done for having a think about that question, about how to fix a mistake on paper.

It is more difficult to fix a mistake on paper than on a computer, so here are some ideas about how you could fix that mistake.

You could get a new page.

If you're using a pencil, you could use an eraser and rub it out.

You could paint over the mistake, or you could leave the mistake in.

Sometimes we have marvellous mistakes, which are actually gonna help our project and make it better, so you could leave your mistake in the project.

Right, time for a quick check now.

When painting, what is easier to do on a computer compared to on paper? Our choices are fix mistakes, use a pencil, get a new page.

When painting, what is easier to do on a computer compared to on paper? Pause the video now and have a think about that.

Well done if you got that right.

The answer was A.

It is easier to fix mistakes on a computer compared to on paper.

People may prefer to use a computer or paper to create artwork.

They may enjoy using both.

Lucas says, "I like painting on paper "because using real paint is fun." I wonder if you might be feeling like Lucas.

Jun says, "I prefer creating art on the computer "because it's easy to fix mistakes with undo." I wonder if you are maybe feeling a bit like Jun.

What do you prefer and why? I want you to pause the video here, and have a think about using a computer and using paper to make artwork, and I want you to decide which one you prefer to use, and maybe think of a reason why.

So I don't want you to just say computer or just say paper.

I want you to think of a reason why you prefer your choice over the other choice, just like Lucas did, and just like Jun did.

Pause the video and do that now, and I'll be here when you get back.

Welcome back.

I could hear lots of people discussing if they preferred painting on paper, or maybe they preferred using a computer to make artwork.

Remember, everybody is allowed to have their own opinion about what they prefer.

Right, we're gonna get ready to do a task now.

I want you to watch this video example of painting on paper.

Right, this is how I painted my painting.

I had a medium-sized paintbrush, and I used that to paint my grass and my stem with the green paint.

Then, I got a smaller brush, and I used that to paint my leaves.

Next, with the cotton bud, I got the yellow paint, and I decided to use lots of dots to do the head of my flower, trying to build out the shape of that flower head, thinking of a dandelion.

Next, once it had dried, I got brown paint, and I tried to add a bit more texture to my painting by painting over.

That was one of the fun parts of the painting, is being able to use different paints on top of each other.

Once that had dried, I got my third colour here, kind of ochre colour on a different cotton bud, using it to add a bit more detail to my flower.

Once that was all done, I went back to my paint brush.

I got the medium brush and some red paint, and this is me designing the wings of the butterfly.

Then, with a very small brush, I went in and did some tiny blue dots on the butterfly wings to decorate it.

Then, I got the black paint to do the butterfly body, and the antenna of the butterfly as well.

On the other side, I got my medium paintbrush, and I used the blue paint to paint out the shape of another butterfly here.

Then, with the orange paint, it's a bit hard to see.

I did some tiny dots on the wings of the blue butterfly too, and then with the same small brush, I did the body and antenna of the second butterfly.

That's my painting all done.

Next, we are going to watch this video example of painting using a computer.

So this is how I painted on computer.

I got my paintbrush tool and the green colour, and I used it to make my grass and draw my stem.

I didn't like my stem there, so I used the undo button to fix it, to draw it again.

Changed the brush size to paint some small leaves.

You could see me using undo there to fix one of the leaves since I wasn't so happy with it.

Undo lets us fix our mistakes when we work on computer.

Now, I'm changing to the yellow paintbrush, and doing lots of clicks to put down my dots to build the head of my flower.

Changing to brown and to a small paintbrush.

Put some tiny dots in the head of my flower, and then changing to a middle-size brush to put some orange dots in my flower.

My flower is looking quite full now.

So I was starting to think about my butterfly shape, changing to a larger paint brush, changing the colour to red, and then changing to black, and drawing a smaller line to build out the body.

Then, using the small size and the blue dots to decorate, and then changing size again to do my blue butterfly wings on this side, and then to a smaller brush to do the black body.

Using undo to fix that body there.

Decorating my wings with a small red brush, and then completing my butterfly.

All done.

All right, we're gonna do our first task today.

Our task is to paint a painting using a computer, so you are free to make any kind of digital artwork that you want to do.

You can use any of your digital painting skills to make your artwork.

Once you're finished, with a partner, I want you to compare making art on a computer to making art on paper.

I want you to talk about which way you prefer, and why.

I want you to use these words to help you.

Let's look at some of our words.

Right, now, you might recognise some of these words.

We've got painting programme.

We've got palette, select, prefer, undo, click, fill tool, paintbrush tool, shape tool.

It's time to pause the video now and go off and work on your artwork, and then with your partner, you're going to use these words to help you compare making art on a computer to making art on paper.

Off you go.

Welcome back.

You were working so hard on your first task.

I know that people made some brilliant artworks, and then probably had quite good discussions about which artworks they preferred, if they preferred making their artwork on paper or on computer.

So you might have said, like Aisha, Aisha said "When I use a computer to create art, "I can select from so many different colours on the palette.

"I prefer making art on the computer." Izzy said, "I still find it tricky to click with the mouse "to create my painting on the computer.

"I like painting on paper more." Remember, everybody is allowed to have their own opinion, so your thoughts might be different from these thoughts, and that's fine.

Right, for the second part of this lesson, we are going to be using commands to recreate a painting.

When we do something that has steps, we need to follow commands in order to get the result that we want.

Did you hear the keyword there? Well done if you heard that keyword, commands.

So commands are instructions that are used to control something.

So you might see in the pictures below that we've got a recipe here, and the person in the pictures is making something.

We follow commands in a recipe to make a cake.

So commands are instructions used to control something.

What do you think would happen if those commands in the recipe were not very clear? Goodness, look what has happened to our recipe.

It looks like it's a bit jumbled up, and that the pictures are sort of zoomed in or focused on maybe the wrong parts of the images.

Are we able to follow this recipe? No.

So what do you think would happen if the commands in the recipe were not very clear? Pause the video and have a think about that.

Welcome back.

Let's see what would happen if we tried to follow this recipe.

The cake might turn out wrong.

It might taste or look different to what we wanted.

The recipe might not even make a cake.

Oh dear.

How would you give commands to help someone else create a digital artwork? So imagine if you were watching a friend draw on one of these faces in a painting programme.

Do you think you could use different words to describe how they would do that? Here are some examples that would help us write really good commands.

Good commands are short.

They are in the right order.

Do you see how in our recipe picture they've got numbers? They've got 1, 2, 3, 4, 5, and 6 to make sure that the steps go in the right order.

The good commands also only say one thing at a time.

They don't try to pack lots and lots and lots of ideas into the sentence.

They only give you one thought at a time, and they are easy to check.

So they're not complicated.

They're really straightforward and easy to check.

Right, let's do a check.

Speaking of checks, we're going to do a check now.

True or false? When giving commands, you should make them as long as possible.

Pause the video and have a think about what the answer would be.

The answer is false.

Why? Commands are easier to understand when they are short.

Well done if you got that right.

All right, our final task of this lesson today, we are going to write commands to create a face picture in your painting programme.

Make sure your commands are detailed and clear.

Use these words to help you.

All right, listen up for these words.

We've got painting programme, first, select, line tool, next, click, fill tool, paintbrush tool, and shape tool.

When you are finished, I want you to swap with someone else there, and then I want you to try and use their commands to make a face picture.

So I want you to follow someone else's commands to see how the face picture turns out in your painting programme.

I am so excited to see these.

So when you pause this video now, I want you to go off and write your commands to create your face picture, and then when you're finished with that, I want you to swap with someone else, and then I want you to use those commands to make your face picture.

Welcome back.

I hope you enjoyed that task.

It's one of my favourite tasks.

So here is an example of how your commands might have been.

First, use the shape tool to draw a circle.

Colour the circle in with the fill tool.

Select the paintbrush tool and paint the eyes.

Change to a new colour and paint the nose and mouth.

Select the line tool and draw the eyebrows.

If you are following my commands, then your painting might have looked a bit like this.

Right, let's summarise the learning that we've done today.

You can create artwork using both computers and paper.

It is more difficult to fix a mistake on paper.

When you make a mistake on the computer, you can use the undo tool to go back and fix the mistake.

Some people prefer to use a computer or paper to paint pictures.

You can follow commands to create an artwork.

Good commands should be short, in order, and easy to check.

Well done for all of your hard work today.

You have completed this lesson.

I hope that you've enjoyed all of this work.

I've really enjoyed working with you today, and I hope to see you soon in another lesson.
