Hi everyone.

I'm Mrs. Courts and I'm very pleased to join you today for our lesson on presenting final designs.

This is part of the Simple Mechanisms, Windmills unit.

Our lesson outcome for today is I can share my final product design.

We've got three keywords for today, and I'm going to say them first, and then you repeat them after me.

Are you ready? Are you listening really nicely? Well done.

Our first word is ordering.

Ordering.

Brilliant.

Well, ordering means putting things in the correct sequence, often using words like first, next and then.

Our next word is sketch.

Sketch.

Well done.

A sketch is a quick drawing based on what you can see.

Brilliant.

And our final word is explain.

Explain.

Super.

Explain means giving information and detail to make something easy to understand.

Well done for listening to those key words.

Are we ready to begin our lesson now? Super.

We've got two parts to our lesson today, and our first learning cycle is presenting your windmill.

These windmills look very different and the designers have made them all very different.

Have little look and see if you can spot anything that you notice that's different.

Have you spotted anything? Brilliant.

Designers use a success criteria to check that their products work and a success criteria for a windmill could include.

Do the sails turn, said Jacob.

And Andeep says, does it have an axle? Remember, the axle is the bar that the sails will turn on, and the sails are the parts pushed round by the wind.

Jacob says, does it stand up by itself? Is it free standing? Hmm, they're good questions, aren't they? We are ready for our first check for understanding.

And our question is, which of these would be a good success criteria for a model windmill? Listen carefully.

Is it A, sails spin when blown? Is it B, is always made from wood? Or is it C, has only one sail? Which of these would be a good success criteria for a model windmill? Pause the video and have a little think.

Well, did you get the answer? Which one of these would be a good success criteria for a model windmill? Would be A, well done.

The sails spin when they are blown.

A windmill doesn't have to be made from wood, and a windmill hasn't just got one sail.

Designers take photographs and draw sketches.

Do you remember what a sketch is? That was one of our keywords.

That's right.

A sketch is what you can see, and then you draw it onto paper.

Well done, or they paint their finished product to share with others.

Here is a photograph of a windmill.

Somebody would've taken that with a camera.

Here is a painting of a windmill.

And finally, this is a sketch of a windmill.

Can you see how they look so different? The painting and the sketch are what the designer has seen with their eyes and then put onto paper.

Where the photograph is taken straight away with a camera and it's instant.

When painting or drawing a windmill, remember to look at each part a piece at a time.

This way you can build up your sketch or your painting.

You might use this order.

So here is a finished windmill, and first of all, if I was drawing this or painting it, I would draw or paint the tower.

Then I'd add details such as the roof, the doors and the windows.

And finally, I would add the axle and the sails.

By doing each part in order, it makes it easier to concentrate and to make sure I've got all the detail that I need.

To paint or sketch a windmill, first, draw or paint the tower.

Can you see that in the picture? Brilliant.

And then add all the details such as the roof, the doors and windows.

And finally, don't forget to add the axle and the sails.

And then you finished your windmill painting.

If you've sketched it, you could then, once you've drawn it, you could colour it all in.

We're ready for our next check for understanding.

Are you ready? Brilliant.

When you paint or sketch your windmill, it is important to remember to, A, paint or sketch it all in one go.

B, choose one part to paint or sketch at a time.

Or C, paint some of it.

So when you paint or sketch your windmill, it's important to remember to paint or sketch in one go, choose one part to paint or sketch at a time or paint some of it.

Pause the video now and have a little go.

How did you get on? Well, did you remember the answer? Brilliant.

So when you paint or you sketch your windmill, it is important to remember to, that's right.

It was B, choose one part to paint or sketch at a time.

To add the finishing touches, you might add details like the brick work and you might add some colour.

There are some parts of our windmill that you cannot see.

The ballast, do you remember what the ballast is? That's it.

That is the heavy material put at the bottom of the windmill to hold it down, to make it more stable.

And so it's freestanding and it will not fall over the ballast.

And you might have used, do you remember? You might have used oats, rice or sand.

So we can't see that part because that's inside our windmill and therefore, we can't see that.

And we also might not see all or most of the axle.

Okay, we could use our wooden dowel.

We could use a straw, a thick straw or split pins.

And again, because of quite a lot of this is hidden inside our windmill tower, we will not see it.

To share parts of your windmill that you cannot see, you could use some labels.

So here is a picture of one of the windmills that's been completed.

And as you can see, inside there is the ballast, which is oats.

Can you see the ballast, the oats, inside that windmill? No, you can't see it because it's hidden inside the windmill tower, the structure.

So therefore, by adding our label, we know we can tell people that that's inside it.

We're ready for our next check for understanding, be sitting nicely.

Brilliant.

So to share parts of your windmill that you cannot see, you can A, add paint, B, add labels or C, add pictures.

To share parts of the windmill you cannot see, what could you do? Pause the video and have a little think.

How did you get on? Did you remember the answer? To share parts of your windmill that you cannot see, you can, that's right.

You could add labels.

Do you remember? If we can't see it, we could add a label to tell people that that ballast or that axle is there.

Well done.

We're ready for our first task now, and the first part is to paint or sketch your windmill and remember to add detail.

And when you've done that, part two is to add labels to share the main parts of your windmill.

You might use the worksheet to cut them out or you might have a go at writing them yourself.

So you've got the word sail, ballast, axle and tower.

You may wish to label other parts of the windmill, but those are the four we're looking for.

Pause video now and complete the first task.

Welcome back.

Well by now, you should have painted or sketched your windmill.

Did you have lots of fun? Brilliant.

Well, Laura shared her work, and this is Laura's painting.

Laura looked at her windmill and then she chose the right colours and she painted her windmill.

She then labelled the parts of her windmill.

Can you see any labels on Laura's windmill? Brilliant.

She labelled the sail, the axle and the tower.

Did you remember to label all of those on your windmill? Brilliant.

Laura forgot to label the ballast that she used.

I wonder if she could add that next time? Did you remember to label the ballast that used? Super.

Laura said, I painted my windmill using the colours on my windmill model.

I took my time and looked very closely to add the detail.

Well done, Laura.

That's a really lovely painting and super labels too.

We're ready for the second part of our lesson now.

Sharing the windmill journey.

To share your windmill journey, think about the different steps you've followed to make the final windmill, the final one.

We've learnt lots of things as we've gone through our lessons, but now we're looking at our final windmill.

So can you see where it says start? Super.

First, we built the tower.

Do you remember building your tower? You might have decorated it as well.

Super.

Then we added our ballast and our support.

This was to make sure that it was free standing.

Do you remember that? Super.

Free standing means it won't fall over.

Brilliant.

After that, we made our sails using our chosen material, the material is what something's made from.

Do you remember that? Brilliant.

And then we chose our axle.

And by choosing our axle, we were able to build our windmill.

Finally, once we'd built our windmill, put it all together, we were able to test our windmill and to see if our windmill worked.

That's very important, isn't it? And this was a painting of the finished windmill.

Yours will look different, but you should have followed the same steps through to make your windmill.

The tower, then added the ballast and support, then the sails, then the axle, and tested it to make your finished windmill.

Now we'll have all done slightly different things to make our windmills.

We might use different materials for the tower.

We could have chosen different materials for the sail or the axle, and you may have chosen a different ballast and a different way of supporting it as well.

This makes all of our windmills unique.

They're all very different to each other, aren't they? Sam said, I learned how to make a sail and Sophia says, I learned how to make a structure and to add ballast.

I wonder if you can help me with our next check for understanding.

Are you ready? Are you listening carefully? Super.

Talk to your friend and tell them one new skill that you have learnt whilst making your windmill.

Remember all the different things that we have done and then see if you can think of something new that you learnt along the way.

Pause the video and join me when you've done this task.

How did you get on? I'm sure I heard lots of super ideas.

So well done.

Well, Jacob says, first I made the axle, but Andeep says, I don't think that was what we did first.

I wonder, can you remember the order of the steps you followed to make your windmill? Is Jacob right? We're ready for our next check for understanding.

Are you ready? So to make your final windmill, which step came first? Came first.

Super, right, well, using our windmill journey, are you going to choose sails, which is A? B, a tower or C, the ballast? Can you pause your video now and have a little think? Welcome back.

Well, I wonder to make your final windmill, which step came first? You should have said the tower.

Can you see the picture of the boxes? The tower was the first thing that you did.

Now, you might have used are the materials than boxes.

You might have used bottles or tubes, but that's the first thing we had to do was build our tower and then decorate it.

Well done.

We're ready for our next task now, task B.

And I would like you to share your windmill sketch or painting with your friends.

Remember to tell them the order of the steps you followed to make your windmill.

What new skills you learnt, what you like most about your windmill and which step you found the most difficult.

That's quite a few things to remember there, isn't it? So share your windmill sketch or painting with your friends.

Think about the order that you followed, what new things you learnt, what things you liked most about your windmill and what you found the most difficult.

And Izzy has said as a reminder look, remember to listen, share and respect others' ideas and work.

That's really important when we do any feedback and any sharing, it's really important to listen and respect others.

Pause the video now and join me when you've had a talk with your friends.

Welcome back.

Well by now, you should have spoken to your friends and talked about the ordered steps, what skills you've learnt, what you liked the most about making your windmill, and which step you found the most difficult.

Brilliant, did you remember what Izzy said? To listen, to share and respect others' ideas and their work.

Excellent, great work.

Here is a painting, and Sam said, I really enjoyed making my windmill.

I found the axle quite difficult, but it was a lot of fun decorating the windmill.

Well done, Sam.

Great work.

Sophia said, your windmill was very good and worked very well.

I really liked the spinning sails and the shiny paint.

Oh, I do like the shiny paint.

Well done Sophia.

Very kind feedback to your friend.

Well, when we've moved through our journey today, we have to remember that everyone's windmills are different.

So we've shared them and we've celebrated these differences, which is really important.

Well done for all of your hard work, and I hope you're very proud of everything you've achieved and your lovely windmills.

We've reached the end of our lesson for today, and I wonder if you can show me your thumbs up if you've met these learning points.

Are you ready? Super.

The final design can be shared with photos.

Brilliant.

The final design can be shared with a simple drawing.

Super.

And the final design can be labelled to show the main parts of the windmill and show how they work.

Excellent.

Well done for all your hard work and all your discussion with your friends and your kindness.

See you again soon.

Bye.
