Hi everyone.

It is Ms. Panchal here.

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

So our lesson today is going to be focusing on the classification keys to identify animals.

So we're going to be using those classification keys to identify lots of different animals.

And this lesson is part of our bigger units of learning on living things and the environment.

So we've got lots of amazing learning to do today.

So let's get started with the lesson.

So the outcome for our lesson today is I can identify animals using classification keys.

So before we get started with our lesson today, we're going to go over some keywords.

Now it's really important we learn how to say these words correctly before we start to learn about them, but also use them as well.

So I'm going to say the word and I'd like you to repeat it back to me.

My turn.

Classification key.

Your turn.

Super job.

My turn.

Identify.

Your turn.

Great job.

My turn.

Observable characteristics.

Your turn.

Super job.

Structure.

Super.

My turn.

Zoologist.

Your turn.

Excellent job everybody.

Well done.

What I'd like you to do now is with your talk partner, I would like you to take it in turns to read the definitions on the board.

So pause the video here, have a go at reading the definitions, and click play when you're ready to continue and we'll get on with the lesson.

Great reading everybody.

Well done.

So our lesson today is split up into two parts.

So the first part of our lesson is going to be using classification keys to identify animals.

And the second part of our lesson, we're going to be thinking about how scientists use classification keys.

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

So Andeep and Jacob are on a school trip at the local nature park and Andeep says, "We have been asked to make a list of the animals we see at the nature park, but there are some animals that I do not recognise!" and Jacob says, "We could use a classification key to help us identify the animals we do not know the names of." So what is a classification key? Pause the video here, have a little bit of thinking time on your own, and then I'd like you to share your ideas with your partner.

What is a classification key? Can you tell me what the word classification means? Can you tell me what the word key means? Have a little think on your own and then share your ideas with your partner.

Off you go.

Great discussion everybody.

Well done and well done for coming up with some brilliant ideas.

So a classification key is a diagram which helps us to identify living things using yes or no questions.

And the questions on a classification key are based on the observable characteristics of living things.

And when we think about observable characteristics is things that we can see.

So for example, this is an unknown animal here.

What observable characteristics does this animal have? So pause the video here and if you need to come up a little bit closer to the board, what observable characteristics does this animal have? What I'd like you to do is write down your ideas on a whiteboard and then share your ideas with the person next to you.

Did you get the same observable characteristics or did you get some different ones? Pause the video here and have a go.

Great job everyone.

Well done.

I can see you've written lots of notes on your whiteboards, well done.

So observable characteristics can be used to decide which group a living thing belongs to.

So if we have a look at this example, classification key, has it got a shell? Yes, it would be a mollusk.

No, we need to ask another question.

Has it got six legs? Yes.

It could be an insect? No, it would be an arachnid.

So pause the video here, use the classification key, yes or no questions to think about what is the name of this animal? Excellent.

It's an insect.

Well done everyone.

So let's move on.

Observable characteristics can also be used to identify and name a living thing.

Has it got one pair of wings? No.

Would it be a butterfly? Yes.

We need to ask another question.

Has it got a striped body? No, it would be a crane fly.

Yes, it'd be a hover fly.

So same as before.

Pause the video here, use the classification key to identify and name the living thing.

Great job everyone.

It's a crane fly.

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

A classification key is a, A, series of scientific definitions, B, series of yes/no questions.

C, series of true/false answers.

What do you think? A, B, or C? Great job, everyone.

The answer is B.

So a classification key is a series of yes/no questions.

Well done everyone.

So let's move on.

Knowing the structure of an animal is useful when using classification keys.

So we've got a kingfisher here, so we can see there's a, this kingfisher has a sharp beak, it has small black eyes, it has wings and it has blue feathers.

So Laura here says, "The parts of an animal's body are called its structure." And so different animals will have different structures, but some of the structure parts may be similar.

The outer structure of an animal includes observable characteristics like skin, claws and eyes on the outside of the body.

So remember the observable characteristics are things that we can see.

So here we've got a tarsier monkey.

Does it have wings? Hands up for yes.

Hands up for no.

Well done.

"No," Laura says.

Does it have fur? Hands up for yes.

Hands up for no.

Excellent.

It does.

Does it have large eyes? Hands up for yes.

Hands up for no.

Excellent job everyone.

Well done.

You got the same answers as Laura.

The structure of these two animals includes a long tail, but what do you observe about their skin covering? So we can see here we've got a kangaroo rat and we've got a bearded dragon.

And one thing that's similar about their structure is they both have a long tail, but actually they're both quite different.

So what do you observe about their skin covering? So pause the video here and look really closely at the two pictures on the board.

If you need to come a little bit closer, what do you observe? So what can you see about their skin covering? Have a go.

Great, so we can see here that the kangaroo rat actually is covered in fur, whereas the bearded dragon is actually covered in dry scaly skin.

So although they both have a long tail, actually their skin covering is very different.

The structure of their ears is also different.

Can you see how? So pause the video here and come up closer to the board so you can see the ears of both animals really closely.

How are they different? Can you see? Excellent.

Well done.

So with the kangaroo rat, they have small round ears, whereas the bearded dragon actually has ear holes.

So we can see that both of these animals here have a long tail, but actually they've got lots of different features of their structure that are quite different to each other.

Well done everyone.

So let's move on to some different animals.

What do you observe about the structure of these animals? So pause the video here and jot down some of your ideas.

I can't wait to hear them.

Great job everyone.

Well done.

I can see you've written lots of great notes down.

Well done.

So the dolphin here we know has a dorsal fin and the crab has large claws.

The dolphin has smooth skin and the crab has a hard shell, exoskeleton.

Although we can observe that these animals live in or around water and animals' habitat is not classed as an observable characteristic, so we can see here, we know a little bit about dolphins and crabs and we know that they live in and around water, but things to do with animal's habitat is not classed as an observable characteristic.

So let's do a check of our learning, which of these do we use when using a classification key to identify animals? Is it A, the structure of the animal, B, the habitat of the animal, or C, the name of the animal? Which one do you think, A, B or C? Great job, everyone.

The answer is A, the structure of the animal.

So let's do another check of our learning.

Which of these animals has a soft, flexible structure? Is it A, a jellyfish, B, a caterpillar, or C, a crab? What do you think? Excellent work everyone.

There's actually two animals here, jellyfish and caterpillar.

So both of these animals have a soft, flexible structure.

Super job, everyone.

Well done.

So let's move on to the first task of our lesson today.

So I would like you to look at the structure of a tapir.

Use the classification key to identify which animal group it belongs to.

So pause the video here and look really carefully at the image of a tapir.

I would like you to use the yes or no questions here in the classification key to identify which animal group it belongs to.

Pause the video here, have a go and we'll talk through the answer really soon.

Off you go.

Excellent work everybody.

Well done.

I can see you were looking really, really hard at that tapir picture.

So does it have wings? It does not.

Does it have gills and scales? No, it does not.

So that means it's a mammal.

Did you get the answer as well? Well done everyone.

Super job.

So the tapir here is a mammal.

Let's look at the next task.

So look closely at the animals on the next slide.

Make a list of observable characteristics of the animals, including the structure of each one.

Use the classification key provided to identify each animal.

So on the screen here, we've got five different animals and what I'd like you to do is use this classification key to identify them.

So what I'd like you to do, and whatever you find is easier is maybe print this slide and the slide of the animals.

Maybe you can move the different animal pictures around or you could draw it out yourself.

Whatever you find easier.

Pause the video here, have a go at the task and we'll go through the answers really soon.

Off you go.

Well done everyone for having a good go at this task.

I can see you are working really, really hard to use these yes or no questions in the classification key.

So let's go through the answers.

So A was a nudibranch, B was a sea urchin, C was a seahorse, D was a basking shark and E was a beluga whale? Did you get those answers too? Well done for having a great go everybody.

I can see you really use your knowledge of animals to help you as well.

Super job.

So we've come to the end of our first part of our lesson.

So we've looked at using classification keys to identify animals, and we're now going to think about scientists using classification keys.

So a French naturalist Jean-Baptiste Lamarck, born in 1744, used classification keys to help him identify different plants and animals that he had discovered.

He used his classification keys to ask questions about observable characteristics that only had a yes or no answer.

Since then, many other types of scientists have used classification keys to help with their work.

Do you know which type of scientist studies animals? Pause the video here, have a little bit of thinking time on your own and then share your answer with your partner.

Do you know which type of scientist studies animals? Can you tell me? Excellent.

Well, well everybody well done.

So some scientists are called zoologists and their job is to discover, identify and study animals in the local and wider environment.

Andeep says, "I'm really interested in studying animals.

I think being a zoologist sounds like a great job.

Do you know the names of any famous zoologists so I can find out more about them?" Jacob says, "I've watched programmes about animals on the television presented by David Attenborough, but he's a naturalist who studies all types of living things, not just animals." So some of you may have also watched documentaries by David Attenborough.

He definitely produces some fantastic documentaries.

Can you help? How else, or do you know what else we can find out about zoologist? How can we find out a bit more about them? So Steve Irwin was a zoologist who studied crocodiles in Australia.

Jane Goodall is one of the world's most well-known zoologist.

She has studied chimpanzees in Tanzania for many years.

And Dr.

Leela Hazzah is an animal conservationist who protects lions and their habitats in Africa.

Now that word conservationist is there.

So this Dr.

Leela Hazzah helps to protect the animal's environment and their habitat to make sure they are living the way that they should be living and that their land is protected.

So let's do a check of our learning.

True or false? Zoologists look after animals in zoos.

Do we think that's true or false? Great job, everyone.

The answer is false.

But why do we think that? Is it because A, zoologists only identify and study animals that live in zoos or B, zoologists, identify and study animals that live in the local and wider environment? So have a little think, which do you think is the correct answer? A or B? Super job everyone.

Well done.

The answer is B.

So zoologists, identify and study animals that live in the local and wider environment.

Well done everyone.

So Dr.

Salim Ali studied zoology and went on to become one of the greatest naturalists of all time.

He grew up in Mumbai, India and developed a fascination for birds from the age of 10.

So he was really interested in birds from a very young age.

He travelled around India to make observations and carry out surveys of birds and he became known as the "Birdman of India" for his work to identify hundreds of birds we recognise today.

So Dr.

Salim Ali here worked really hard to study birds and learn lots about them, but he started from a young age, so he developed some really fantastic knowledge all about birds.

So some scientists, including zoologists and naturalists, use classification keys to identify and group animals.

Dr.

Salim Ali may have used a classification key like the one on the next slide to identify birds.

So here we've got a classification key.

So can you identify this bird? What I'd like you to do is pause the video here and go through the classification key in the yes or no questions to identify this bird.

Click play when you're ready to continue and we'll go through the answer.

Great job everyone.

Well done.

So the bird can be identified as a crow.

Well done everyone.

So we first look at the first question, are the feathers all in one colour? We'd say yes.

Does it have an orange beak? No.

So we know that it's identified as a crow.

Did you get the same answer? Good job everyone.

Well done.

So Andeep here says, "Classification keys are not just for people who don't know about animals.

Scientists including zoologists and naturalists use classification keys too." Jacob says, "Yes, when zoologists discover animals they have not seen before, they use classification keys to help identify and group them." So let's do a check of our learning.

Which type of scientists might use a classification key to identify and group animals? A, a chemist, B, a naturalist, C, zoologist, D, geologist.

What do you think A, B, C, or D? Excellent work, everyone, well done.

It's B, naturalist and C, zoologist.

So let's move on to the next task for this lesson.

So I would like you to use the classification key on the next slide to identify these birds, we've got bird A, B, and C.

These are the birds that I saw at the nature park, but I don't know what type of birds they are.

So let's help Andeep.

So what I'd like you to do is use the classification key here to identify bird A, bird B, and bird C.

So what I'd like you to do is pause the video here, use the key to help you identify the different birds.

Click play when you're ready to continue and we'll go through the answer.

Off you go.

Excellent work everybody.

Well done.

I can see you are working really hard to look at the different birds carefully, but also answer the yes or no questions accurately.

So well done everyone.

So bird A is a black bird, bird B is a bullfinch and bird C is a pigeon.

Well done everyone.

Did you get those answers too? Super job.

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

So let's do a recap of our learning.

A classification key is a series of yes or no questions about the observable characteristics of living things.

Knowing the structure of an animal is useful when using classification keys.

Zoologists discover, identify and study animals in the local and wider environment.

Scientists including zoologists and naturalists, use classification keys to identify and group animals.

So we've done lots of learning on classification keys and we've had lots of practise of identifying animals and I know you've used your fantastic knowledge of animals to help you in today's lesson as well.

Well done for all of your work.

I've been so impressed with all of your learning today.

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

Bye-Bye.
