Hi everyone.

I'm so pleased you've come to learn with me today.

I'm Mrs. Horan and I'm really looking forward to learning all about how animals grow and change with you in today's lesson.

Today's lesson is part of the unit on new life.

This lesson is called Growing Up, and we will be learning all about how animals change as they grow and get older.

The outcome for our lesson today is to group and order different stages of an animal's growth.

This lesson builds on what you already know about different types of animals and is part of our big learning question, how do living things grow and reproduce? There are five keywords in our lesson today.

We'll take a quick look at them now, and I'd like you to have a go at saying them with me, so we'll do my turn, your turn for each one.

Are you ready? My turn, animal.

Your turn.

My turn, offspring.

Your turn.

My turn, grow.

Your turn.

My turn, change.

Your turn, and my turn, adult.

Your turn.

Fantastic.

Now, a lot of those words are probably quite familiar to you, but we'll still have a really good look at each one of them as we come to them in the lesson, so don't worry if you're not sure about any of them now, I'll have plenty of time to get to with them later on.

Our lesson is divided into three parts.

Let's get started with the first part.

Animals grow and change.

Animals have babies which are known as their offspring.

Can you see there are two keywords in that sentence? Let's have a think about each one.

The first one is animals.

Can you say that? My turn, animals.

Your turn.

Great.

We already know that animals are living things that move and each other animals are plants.

Now, for the other one, you might be a bit less familiar with this word.

My turn, offspring.

Your turn.

Fabulous, you might remember that the offspring of an animal are the babies or young that it has.

Let's take a look at some animals and their offspring.

Here, is a young gosling with its adult goose parents.

Can you see how the young bird is a different colour and looks fluffier than the adult bird? It's a similar shape though with two legs, two wings and a beak.

Here, we have a hippopotamus and its offspring, which is called a calf.

The calf looks very similar to its parent, doesn't it? Just smaller.

Can you think of any other animals and their offspring? Maybe you can remember some from other lessons you have done or maybe you've seen some animals and their offspring at a farm or zoo.

Offspring are young animals.

Their parents are the fully grown version of this animal.

When an animal is fully grown, it doesn't get any bigger.

A lamb is the offspring of a sheep.

A sheep is the fully grown version of a lamb.

Can you see how the adult sheep is different to the lamb in the photograph? It is much bigger and its wool is thicker.

Over time, offspring grow and change into adults.

Wow, we have a lot of important words in that sentence, don't we? Now we've already looked at the word offspring.

Let's have a look at the next one.

My turn, grow.

Your turn.

Great.

When something grows, it gets bigger in size.

You have grown since you were babies and you are still growing out, and next word is another one that you are probably familiar with.

My turn, change.

Your turn.

That's it, if something changes, it means it does not stay the same.

Can you think of any ways you have changed since you were a baby? You've probably grown some teeth and you have more hair now.

Now let's think about that last word in the sentence.

My turn, adults.

Your turn.

Great, an adult is the mature or fully grown form of an animal.

I bet you've heard people use that word adult before to talk about grownups.

Well, it's not just used for humans.

We can use that word adult to describe fully grown animals of any type.

Here is an adult of fully grown crocodile.

A hatchling grows and changes.

It becomes a crocodile, so the offspring is called a hatchling.

Then after some time growing and changing, it becomes an adult.

Crocodile hatchlings look similar to adult crocodiles, just smaller.

This is true for many animals, but not all of them.

Some look very different when they are young and when they're adults.

For example, a tadpole grows and changes too.

It becomes a frog, you probably know that tadpoles look like small black blobs with little tails, whereas adult frogs look like the picture you can see there.

They have four legs and no tail, so some animals change a lot as they grow from young offspring to adults.

Let's see how you're getting on with a quick check for understanding.

What are offspring? Are they A, parent animals, B, adult animals, or C, young animals? The answer is, C.

Offspring are young animals.

Now, for something a little trickier, think about this statement and decide whether you think it's true or false.

Offspring do not grow or change.

That statement is false.

Now, can you explain why? Do you think it is false because A, over time offspring grow, change and become fully grown animals or do you think it is false because B, baby animals are called offspring or young? So the statement is false because over time all offspring grow, change and become fully grown animals or adults.

A fully grown version of an animal is known as an adult.

Here are some pigs.

Can you see which one of the pigs in the picture is the adult? That's right.

The biggest one is the adult.

The one that is fully grown.

A female pig is called a sow.

The offspring of a sow is called a piglet.

Can you see the piglets in the photo? They are the sows offspring.

A female piglet grows into an adult pig called a sow, so one day all of those little piglets in the picture will have grown and be adults too.

Jun, Laura and Andeep are talking about animals.

Jun says, "An adult is a fully grown animal." Laura says, "An adult is a young animal." Andeep says, "An adult is the offspring of an animal." Who do you agree with? This is quite tricky because the children have used a lot of words we've talked about today, so think carefully about what each child has said.

Pause the video here to have a think about who you agree with and maybe talk to a partner about your ideas and come back when you are ready to see who is right.

Did you agree with Jun? He's correct because the word adult means fully grown animal.

Let's put all our new learning into action with a practise task.

Look closely at the photographs.

We have a seal and its pup and a sheep with its lamb.

In what ways have they changed from offspring to being an adult? Observe the photographs really carefully and see if you can spot all the differences between the younger offspring and the fully grown adult animal.

Pause the video here to have a good look and then come back with all your ideas.

What did you find that? Did you think it was easy or challenging to find differences between the young and fully grown animals? Sam looked at these pictures too and she thought the pup has plain white fur and this changes to a black spotty pattern as it grows into an adult seal.

Izzy looked at the picture of the sheep and its lamb and she noticed that the sheep is bigger than the lamb.

Its fleece changes as it grows and becomes longer and darker than the lamb.

Are your ideas similar or different to these? Maybe you notice something that Sam and Izzy didn't.

Let's move on to the second part of our lesson now, grouping animals.

Jacob is looking at photographs of animals and their offspring.

He decides to put them into groups.

Jacob says, "When we group things, we look at what is similar and what is different." We are really good at thinking about similarities and differences now after comparing all those pictures of adult animals and their offspring, so I think you're going to do a really good job of sorting animals into groups.

There are lots of ways we can group animals.

One way is to group animals by their stage of growth.

Animals that are starting to grow or at early stages of their growth are young animals.

There is a picture of a young chick in the photo there.

It's still small and fluffy and it's not been outta its egg for very long.

It's not finished growing or changing yet.

Animals that are fully grown are adults.

You can see from the picture of the adult hen there, it is bigger than the chick and its feathers are a different colour.

It is finished growing and changing by now and will look this way for the rest of its life.

We can use sorting hoops to group animals at different stages of growth.

You can see we have two sorting hoops on screen here.

In the first one on the left, we have young animals.

These animals are still growing.

There is a chick and a kitten in this hoop.

On the right, we have adult animals.

The animals in this hoop are fully grown.

There is an adult hen or chicken and an adult cat in this hoop.

Let's see how you're doing with your learning in this part of the lesson, which two things do we look at when we group things? Do we look at A, what is different? B, how many are there or C, what is the same? Now remember, you are looking for two of these answers this time.

What do you think? The correct answers were A and C.

When we group things, we look for what is different about them and what is the same? Sofia has grouped these animals by looking at how much they have grown.

In the sorting hoop for young animals, she has put a frog, some owlets and some tadpoles.

In the hoop for adult animals, she has put an owl, a cygnets, and a swan.

Can you spot any mistakes Sofia has made? Pause the video here to have a really good look at how she has sorted the animals and see if you can spot which ones are in the wrong group.

There was one animal in each hoop that needed to move to the other one.

Did you find them? The cygnet is in the early stages of growth, so that belongs with the other young animals and the frog is fully grown, so Sofia needs to put it with the other adult animals.

Time for you to try sorting some animals yourself.

You sorting hoops to sort these animals into young and adult groups.

The animals we have to sort are a kitten, a goat, a chick, a rabbit, a sea turtle, a blackbird, a hatchling, and a kid.

Then, when you've finished sorting the animals into which are young and which are adults, see if you can think of any other ways to group the animals.

It's completely up to you how you sort them into your own groups.

You might want to think about what they look like? How they move? Or what type of animal they are? Or any ideas of your own.

Pause the video here to have a go at these tasks and come back when you're finished sorting your animals.

Welcome back.

Let's take a look at where the animals belong when we are grouping them into young animals and adult animals.

In the hoop for young animals, we should have the kitten, the chick, the hatchling, and the kid.

Did you know that young rabbits are called kittens just like young cats? Sometimes the same word is used for different types of young animal.

For example, both young cows and young elephants are called calves.

Now, for the adult animals, we should have the goat, the rabbit, sea turtle, and the blackbird.

How many did you get in the correct hoops? Did you think of any different ways you could have grouped the animals? Jun grouped the animals based on the number of legs they have.

Laura put the animals into two groups, fur or no fur.

And Andeep grouped the animals into wild animals and pets.

Did you sort your animals in any of these ways or did you do something different? We've come to the third part of our lesson now, ordering animals.

Scientists often look for patterns to try and make sense of the world around them.

They observe things and put them in order by age, size, height, or using other measurements.

Laura is thinking about grouping, ordering and patterns in her family.

She says, "I can order my family in different ways.

I can put them in order of how old they are." "I can also put them in order of height or shoe size." We can sequence animals by their stage of growth.

This means putting them in order by their age.

That word sequence means putting something in order and stage of growth means by how much they have grown.

We can use an arrow like the blue one you can see here to show the direction of growth.

Alex has a tip here to help us sequence animals by their stage of growth.

He says, "We put the youngest animal first.

Use your observation skills and look carefully at each animal." Let's see an example.

Here, we have a lamb and a sheep.

The lamb is the younger of the two animals, so we put it on the left hand side under where it says youngest.

The sheep is the older of the two, so that goes on the other end, under oldest.

The arrow shows us that the lamb grows into the sheep.

Let's do a quick check for understanding on one of those words we've just used.

When we put things from youngest to oldest, this is called, what is it called? Ordering, sorting, or researching? Great, when we put things from youngest to oldest, this is called ordering.

Now it's time for you to have a go at some sorting and ordering.

Can you match the baby and adult animals? Remember to start with the youngest animal and draw an arrow to show how it grows into the older adult animal.

The animals we have to sort and order are boar piglet, owlets, woman, wild boar, kangaroo, baby, joey and owl.

When you've done these ones, you can add some of your own examples too.

Pause the video here to have a go and come back when you are ready to check your answers.

Hello again.

Let's see how you did.

We have the young joey, which grows into a kangaroo.

A human baby, which grows into an adult woman.

A young boar piglet, which grows into a wild boar.

And some young outlets who become fully grown owls when they are adults.

Did you add any of your own examples too? You might want to show these to a friend and see what animals they did as well.

That brings us to the end of our lesson, what a lot we have learned today.

Let's take a look back at the key learning from today's lesson.

Offspring are young animals.

Offspring change and grow into adults.

We can group animals at different stages of growth by looking at what is similar and what is different.

We can order animals at different stages of growth using our observation skills.

Thank you so much for joining me today to learn about how young animals grow and change as they become adults.

You did some great work sorting, grouping, and ordering the animals and are very quickly becoming animal growth experts.

Thank you for your hard work today, everyone.

I'll see you again next time.
