Lesson video

Hi everyone.

It's Ms. Panta here.

I hope that you are well and you've had a great day so far.

I'm really excited that you've decided to join me on today's science lesson.

So we're gonna be learning all about electrical appliances today, and that's part of our bigger unit of learning on simple electric circuits.

We've got lots of learning to do today, so let's get started.

So the outcome for our lesson today is, "I can identify and name common appliances that run on electricity." So here are some key words for today's lesson.

So we've got electricity, electrical, appliance, and group.

So some of you may have heard some of these words before and some of you may not been so sure, but don't worry too much because we're going to talk about all of these keywords in today's lesson.

So let's talk through now some of the definitions.

So what I'd like you to do now is pause the video here and take it in turns with your talk partner to read out each sentence.

Have a go and then click play when you're ready to continue.

Super job everyone, well done.

So our lesson today is split up into two parts.

We're first going to think about electrical appliances and we're then going to move on to grouping electrical appliances.

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

So think of the different things you have done today.

Think about from where you are now, what have you done earlier on in the day.

And how many of these things involved using electricity? So pause the video here and with your talk partner, maybe jot down your ideas on a whiteboard.

Think of all the things that you've done today and how many of those things actually included electricity.

Have a little think and jot down your ideas with a talk partner and click play when you're ready to continue.

Super job everyone, well done.

I hope that maybe when you have been, were writing down your ideas, you realised that actually quite a lot of the things that you did needed electricity in order to work.

So for example, you may have thought of a clock, an alarm clock to wake you up on time.

Television, you may have watched on television today, or using a mobile phone.

So electricity is an essential part of modern life.

So the word essential means really important, and something that we need.

This means that it is extremely important to how we live our lives.

Now, nowadays, in modern day we use electricity for so many things and we rely on it so much.

Now, some devices need electricity to perform different functions and these are called electrical appliances.

Now, some of you may have seen these before, some of these, you may have these in your home.

So we've got a drill, if you're making a bookshelf, for example, you may need a drill.

A hair dryer to dry your hair after you've washed it.

An oven to cook your food, or even a washing machine to wash clothes.

So these are a few examples of electrical appliances, and electrical appliances are things that help you in your everyday life, but more things so that things that will help you cook and clean for example.

How many electrical appliances can you name? So pause the video here and have a think on your own first and then share your ideas with your talk partner.

How many electrical appliances can you name? Off you go.

Super job everyone, well done.

So there's lots of different types of electrical appliances.

For example, a toaster, how you would cook your toast, that's an electrical appliance.

For example, hair straighteners, how I make my hair straight, I use electricity and I use an electrical appliance in order to make my hair straight.

So there's lots of different electrical appliances that you use in your home, but also that can be used at school as well.

Good job everyone.

So let's do a quick check of our learning so far.

True or false, electricity is an essential part of modern life.

Do we think that's true or false? Have a think.

Excellent, the answer is true.

We've said that electricity is a really important part of our modern life, and let's have a little think about why.

Do we think A, we need electricity to keep ourselves alive? Or B, many of the tools and equipment we rely on each day need electricity to work? So which answer you think do you think is correct? A or B? Super job everyone, well done, the answer is B.

So many of the tools and equipment we've relied on each day need electricity to work.

Let's move on to our next question.

An electrical appliance is a device that uses electricity to perform a function? B, produces electricity to perform a function? Or C, uses electricity to carry out investigations? So think about what we've just spoken about and learnt about electrical appliances and think about which answer is correct, A, B, or C.

Have a think and we'll go through the answer soon.

Excellent work everyone, well done.

The answer is A.

So an electrical appliance is a device that uses electricity to perform a function, whether that's washing clothes, whether that's screwing a nail into a piece of wood with a drill, whether it's a TV.

Well done guys.

So the first electrical appliances such as the iron, kettle and light bulb were invented in the 1800s.

So we've got an example here of an early electric iron.

And so ultimately with the modern day iron, it does exactly the same job, but this is what it was like when it was first invented.

And we've also got an example of an early electric kettle, again, does a very similar job to what a kettle does now that's in our kitchen, but it just looks quite different.

So Thomas Edison was a famous American inventor who is often credited with inventing the first electric light bulb.

So Thomas Edison is a significant figure within the science and (indistinct) world because he was a very famous American inventor.

So here we've got a picture of Thomas Edison and we've got a a picture here of an early electric light bulb.

Let's do a check of our learning.

Which three of the following electrical appliances where invented in the 1800s? A, iron.

B, television.

C, kettle.

D, light bulb.

If you need to go back to the last couple of slides just to refresh your memory.

Have a go at the question and we'll talk through the answer here soon.

Super job everyone, well done.

So the three electrical appliances that were invented in the 1800s is an iron, a kettle, and a light bulb.

Well done everyone.

So we're going to move on to the first task for today's lesson.

So I would like you to make a list of electrical appliances around your school and home.

Be careful not to touch any of the appliances.

Then, working with a partner, I would like you to use actions and no words to mime how to use the electrical appliances on your list.

So it's like playing a game of charades.

So you can't use your words to show and explain the electrical appliance, but you need to use your actions.

So use your hands, use your arms, use your legs even maybe.

How many of the electrical appliances can your partner guess correctly? So the first part of the task is to make the list of electrical appliances and the second part of the task is to work with your partner to play a little charade game and actually practise acting out using some of the electrical appliances.

Have a go at this task, have fun with your charades game and I look forward to hearing all of your different actions that you used.

Off you go and have fun.

Fantastic work everyone, well done.

I know you worked really hard to think of different actions that you can use to show the different uses of the electrical appliances.

I'm so impressed, fantastic job everyone.

So Jun says, "I mimed using a remote control to switch the channels on my television." Does anyone know what Jun was pretending to use? Excellent, it was a television.

Andeep says, "I mimed putting bread into the electrical toaster in my kitchen at home." And what was Andeep miming? A toaster, excellent, well done.

Maybe you chose a television and toaster or maybe you chose different appliances, but well done for having a great go, everybody.

Fantastic work.

So we've learned a little bit about different electrical appliances and we're now going to move on to grouping electrical appliances.

So we're using our knowledge of electrical appliances and using that to help us group them.

So let's move on.

So Andeep makes a list of old toys that he would like to donate to a local charity.

Now, donating your old toys to a local charity is a fantastic way of giving back to the community.

So these are a couple of things that he made a list of.

So you've got basketball, a toy robot, a jigsaw, a remote control pet, a games console, a skateboard and a piano keyboard.

And Andeep's dad says, "These days all toys played with by children are electrical appliances." Do you agree with Andeep's dad? Why? So pause the video here, have a little think about what Andeep's dad has said.

So we've learned about electrical appliances, what they're used for, but Andeep's dad is saying these days all toys played with by children are electrical appliances.

Do you agree with Andeep's dad or do you think something different? Pause the video, have a think with your talk partner and then we'll go through the answer.

Off you go.

Excellent work everyone, well done.

So whilst lots of children's toys do need electricity or batteries, we do not say that toys are electrical appliances.

Electrical appliances are things that we use every day for cooking for example, or cleaning.

So that we know that there are lots of games and toys that will require electricity but we do not say that they are electrical appliances.

Well done everyone.

So Andeep decides to sort his toys into groups to show that his dad is incorrect.

What would be the headings for these two groups of toys? So we've got two different groups here and we need to think about what's inside both of these groups to think about then what the headings would be.

So in one group we've got a jigsaw puzzle, a basketball and a skateboard.

And in the other group we have some other toys, including a robot and a games console.

So pause the video here, have a think with your talk partner.

If you need to come up a little bit closer to the board to see the toys better.

What would be the headings or the names of these two groups of toys? Have a little think.

Excellent work everyone, well done.

So the first group here which has the jigsaw puzzle in, the basketball and the skateboard.

That heading could be, "Non-electrical toys" Because they do not need electricity.

Whereas on the right hand side, this other group we could call that group, "Electrical toys." Did you get those headings? Well done by having a good go.

So Sam looks at Andeep's group of electrical toys.

So in the electrical toys we've got a toy robot, remote control pet, games console, piano keyboard.

And Sam says, "Some of these toys are not electrical because they need batteries." What do you think about what Sam is saying and why do you think that? So Sam's saying that some of these toys are not electrical toys because they need batteries.

What do you think about what Sam's saying? Do you think she's right or do you think she's maybe not right? Excellent job everyone, well done.

So some electrical appliances need to be plugged into electrical sockets in the wall.

Now, you will have electrical sockets all around your home and in the classroom too.

The appliances need main's electricity, which comes from a power station and is sent to your homes.

Whereas some electrical appliances use batteries and this means they can work without a power cable so you can move around with them.

So there are different sources of where electricity can come from.

And so some appliances will need electricity from the mains, so you would need to have something plugged into the wall and a wire connecting it to the appliance.

But actually there'll be some appliances that can actually just use batteries, which means you can move it around.

Let's do a quick check of our learning.

Which of these can be used to provide electricity for electrical appliances? A, twisted elastic bands.

B, mains electricity.

C, batteries, or D, wind up handles.

So have a think back to the learning that we've just done and which of these can be used to provide electricity for electrical appliances? Have a little think.

Super job everyone, well done.

So B, mains electricity which is from the wall, we say we got that wall socket, and then C, batteries.

Well done everyone.

Let's do another check of our learning.

True or false? All electrical appliances have to be plugged into the mains to work.

Think about whether that's true or false.

If you need to go back to the last couple of slides just to refresh your memory.

Amazing work everyone.

The answer is actually false.

So we now need to think about why that is false.

Is it because A, some electrical appliances need electricity from batteries, or B, some electrical appliances work without electricity.

So why do we think this statement is false? Have a think.

Is it A or B? Super job.

So we learned earlier in the lesson today that some electrical appliances actually need electricity from batteries and they do not need to be plugged into the mains.

Fantastic work everyone, well done.

So Sam decides to sort Andeep's electrical toys into two groups.

So we've got, "Uses batteries" And we've got, "Uses mains." So in the uses battery section group we've got toy robot, remote control pets.

And in the uses mains group we've got games console and piano keyboard.

Now Sam says, "I wonder if any of these toys can be in both groups." What do you think? Have a think with your talk partner.

Excellent, well done.

So there are some games consoles for examples that will actually use batteries.

So whilst most games consoles will need to use mains electricity, there are actually some maybe smaller consoles that you would be able to use batteries for.

And there are some appliances and some objects and things that will need to use batteries but actually could be placed into mains as well.

Sometimes there's options of both, sometimes depending on the size of the object and size of the toy or the appliance.

So let's do a quick check of our learning.

Which of these would be possible ways to sort and group appliances? A, electrical and non-electrical.

B, living and non-living.

C, battery and mains.

What do you think? Super job everyone, well done.

So there are two different ways actually that we could possibly sort and group appliances.

So we could sort and group them using the subheadings, "Electrical and non-electrical" Or we could use the headings, "Battery and mains." So let's move on to the next task now.

So I would like you to look at the everyday objects on the next slide and sort them into the groups electrical or non-electrical.

And then once you've done that, I would like you to sort the electrical objects into the groups that uses batteries or uses mains electricity.

Now, I would then like you to think about are there any objects that might go into both groups? So there's two different parts of the task here.

1A and 1B.

So what I'm going to do now is go onto the next slide that has the different objects and you may want to print that slide out or you can draw your own ones or you can write your own ideas down.

It's completely up to you.

But first you need to sort them into the groups of electrical and non-electrical and then sort the electrical objects into groups of uses batteries and uses mains electricity.

And once you've done that activity, I would like you to think about any of the objects that might actually be able to go into both groups.

So here are the different objects for you to work with.

So pause the video here, have a go at the activity and click play when you're ready to continue and we'll go through some of the answers.

Off you go.

Super job everyone, well done.

I know that was quite tricky 'cause there was lots of different objects and things we need to think about, but I know you've worked really, really hard to group them.

So the first part of the task was to sort the everyday objects into groups.

So we've got electrical and non-electrical.

So in the electrical group we've got food blender, a train set, a kettle, a microwave, remote controlled car, mini quad bike and digital scales.

And then in a non-electrical group we've got a whisk, a coffee grinder, a pasta maker, a windup car, and a kite.

So in this example the whisk that they had given you a picture of is actually a non-electrical one because you need to use your hand to to twist the top of it round and round so that it whisks, but actually nowadays you can get electrical whisks as well.

So the second part of the activity was to sort the electrical objects into the groups of uses batteries and uses mains electricity.

So in the uses batteries group we've got remote controlled car, mini quad bike, digital scales, train set and a drill.

And in a uses mains electricity group, we've got a food blender, a microwave and a kettle.

So some drills and train sets can use a mains electricity as well so could go into both groups.

Fantastic work everybody, well done.

I know there was quite a few different things to do in that task, but you all did such a fantastic job.

Well done.

So we're going to move on to the next part of the task now.

So what I'd like you to do is find objects in your home and school and use your sorting skills to group them into these headings, "Electrical" And, "Non-electrical." Once you've done that, I would then like you to sort all of the electrical items into these headings, "Batteries" And, "Mains." So this activity is very similar to the one you just completed, but I would like you to find the objects now.

So look around your home or look around your school.

If you need to, have a look at some ideas from the previous task to help you.

But pause the video here, have a go at the task and we'll go through some example answers really soon.

Off you go.

Fantastic job everybody, well done.

You did such a good job there.

I know it was quite tricky to find different objects around your home and school, but you all did such a fantastic job.

So here are some examples you may have found.

So in the electrical section you may have found a toaster, computer, alarm clock, television or phone.

And in the non-electrical section or group you may have had found a pencil sharpener, a bin, carpet, drinks bottle, or even a human.

So here are just a few examples of different things you may have found, but there are obviously lots of different options and lots of other examples you could have used.

And so when the next part of the activity was to sort all of the electrical items using the headings, "Batteries" And, "Mains." So for this example, alarm clock, and phone go in batteries, and in the mains we have toaster, computer and television.

So did you get any of these items or did you find different ones? Well done for having a great go at this task everyone.

I'm so impressed.

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

So let's do a summary of our learning.

So electricity is an essential part of modern life.

Humans have used electrical appliances since the 1800s, and some electrical appliances use batteries and some use mains electricity.

And appliances can be compared and sorted into different groups.

So our lesson today, we've learned a little bit about electrical appliances, but actually we've learned that electrical appliances can use batteries but also some can use mains electricity.

Well done for all of your work today.

You worked incredibly hard and gave me lots of fantastic examples of different electrical appliances.

I hope you have a great rest of the day and I'm sure I'll see you in the next science lesson really soon.

Bye-Bye.
