Lesson video

Hello, everybody welcome to your second lesson on ecosystems with me Mrs. Roberts.

I'm so happy to be back here.

And I'm glad that you joined us for our second lesson, because today we're going to learn about how we classify the diets of animals.

Now, the diet is everything that we eat.

The diet is everything that we eat well done.

So Lenny the lion here is again by my screen, and he's really excited about today's lessons because we get to do some drawing and he's really excited to do some drawing.

So he always sits by my screen and helps with my learning.

If you want to go and get your favourite teddy to listen to all of your learning state, you can do so but you'll also need pencil or pen, a ruler and a notebook.

So, pause the video and go and get all of the resources that you need to get now.

Okay, so in today's lesson, we're going to do the following.

We'll go through our star words.

Then we'll learn about herbivores.

Then we'll learn about carnivores.

Then we'll learn about omnivores.

And then we're going to draw a Venn diagram.

We have got a jam packed lesson today team.

So let's get started.

As ever we're going to start with our star Words.

Star words, star words, star words.

Well done, you remember from last lesson.

The first three star words I'm going to introduce you to today.

All have different prefixes for the same root word.

Now the root word is vore.

Can you say vore? and vore means to feed, vore means to feed, well done.

So the first word is carnivore.

You can see carni.

The prefix is underlined and that means flesh.

So carnivore, you're turn carnivore.

You're turn, well done.

Carnivores, eat only meat, carnivores eat only meat, well done.

The next one is herbivore.

Can you say herbivore? What's the prefix for this one? Herb, well done.

Now, what do you think that means then if a carnivore only eats meat a herbivore only eat plants well done.

So my turn, your turn, herbivore, herbivore, herbivore only eat plants, your turn well done.

And the last one is omnivore.

Can you say omnivore.

Now this prefix is omni.

Can you say omni, well done.

And omni means all, omni means? So an omnivore eats both plants and animals.

An omnivore eats plants and animals.

Well done wow.

You've done those so well.

Let's quickly recap our star words from last lesson two, habitats, you're turn.

Micro organism, you're turn, and ecosystem your turn.

Well done you remember those ones from last lessons so well and learned the new ones for today.

I'm going to give you a rainbow cheer, which goes like this because you're working so hard, well done.

So let's think about herbivores.

Herbivores are animals that eat only plants.

They need a lot of energy to stay alive and many have to eat all day long to get enough energy.

Some herbivores have a special digestive system so they're able to eat grasses.

Commonly recognised herbivores include deer, rabbits, cows, sheep, goats, elephants, giraffes, horses, and pandas.

Which animals can you see on the screen that are herbivores? Can you tell me those four examples? What's the second one? Elephants, well done.

What's that third one munching on a long sugar cane? Good, that's a panda and what's the fourth one with little ears? Good, it's a rabbit.

These are all herbivores.

These are all herbivores.

As an example, manatees live in ocean waters off the coast of Florida.

A giraffe lives in Africa and eats leaves from the trees.

And they especially like the leaves of the Acacia tree.

A giraffe may even eat 75 pounds of food a day, which is lots, and lots, and lots of food.

So herbivores eat only plants.

Let's now look at the animals that eat only meat.

And these are called carnivores, well done.

So, a carnivore is an animal that get its food from other animals.

They're also called meat eaters.

Carnivores come in all shapes and sizes.

Ranging from two ounce weasels, to half tonne bears.

And they eat everything from birds, fish, and reptiles, and sometimes even each other.

Can you imagine? So here are some examples of carnivores.

Wild cats, such as lions and tigers, are examples of vertebrate carnivores.

That's a ladybird and a starfish.

The other carnivore that you also will know about is a spider.

So they only, what do they catch in their web? Well done they catch flies.

So they eat other living things which are animals.

Here's a task to see how well you were listening about herbivores and carnivores.

First question, can you read it with me? Name three examples of organisms that are herbivores.

Can you remember three of those animals? Why do some herbivores have a special digestive system? What do they need to digest? And why are carnivores sometimes called meat eaters? Team I'm going to give you some time to answer these questions and I'd like you to write them down.

If you've forgotten or you need to listen again to some of the information that I've given you this lesson, then go back on the video and re-watch about herbivores and carnivores now.

Pause the video and write the answer to your questions now.

Well done, pause the video.

if you need more time because I'm going to go through the answers.

The three examples that you could have had for herbivores were goat, panda, and elephant.

If you had some of the others from my video, then don't worry that's okay.

Herbivores need a special digestive system because they need to be able to eat grasses.

Question three, why are carnivores sometimes called meat eaters? Because they only eat meat.

Omnivores are animals that eat both plants and animal derived food.

Although the Latin term omnivore literally means eater of everything.

Omnivores can't actually eat everything because I couldn't eat a table, so it's every living thing.

While that food options are greater than those of herbivores and carnivores, they are still limited by what they can find to eat or what they can catch.

Many will eat the eggs of other animals.

And some omnivores are scavengers, which means they even eat dead animals.

Some examples of omnivores that eat both meat and plants are humans, bears, pigs, and chickens.

Here's a game for you.

I want you to read what it says on the screen.

And then I want you to tell me is it a herbivore, an omnivore, or a carnivore? So on the screen it says an animal that eats only plants.

Hmm, which ones that can you tell your screen nice and loud? Well done, it's a herbivore.

I'm not going to read them out for you now.

I'm going to let you read it on the screen.

Which one do you think that is? Can you tell your screen? Herbivore, carnivore, or omnivore? Let's see if you're right, well done.

That's a carnivore, they eat only meat.

And finally an animal, can you read the rest of it? What do you think? Omnivore, well done.

You've done that so well.

Now just to make something very clear, I am a vegetarian, but I know that for instance my brother is not a vegetarian.

Does that make me a herbivore and my brother an omnivore? Hmm, that's interesting.

No, it doesn't because my digestive system is the same as my brothers.

We are both omnivores but I choose not to eat meat and he chooses to eat meat.

So some people may be a vegetarian but that does not make them a herbivore.

All humans are omnivores.

All humans are omnivores, well done.

I just thought I'd make that nice and clear.

Okay, so now we're going to classify them into groups.

I'd like you to draw this table and then we'd like to tick which animal on the screen, depending on their diet.

So for instance a human, are they a carnivore, a herbivore, or an omnivore? Well done, they are an omnivore.

So along the row of human, I'd like you to tick omnivore.

Pause the video and draw this table now.

Okay, I'd like to make sure you've got all of your ticks in.

I'm about to go through the answers.

So are you ready? Here we go.

A human is an omnivore.

A spider is a carnivore.

A rabbit is a herbivore and a bear is an omnivore.

If you've got all of those right you can give yourself a big tick at the bottom of your page.

Well done or if you set it to your screen, you can give yourself a pat on the back.

The last part of our lesson now is about Venn diagrams. Can you say Venn diagram? Venn with a V, Venn diagram.

Your turn, well done.

This is what a Venn diagram looks like.

It's two circles joined together.

They help us to classify different things into groups.

So for instance, we can place things into one of the circles, which means it's part of that group.

Or we could place it into the other circle which means is part of that group.

There's also in the middle, a section where the circles crossover.

And if I play something in that section, it means it's both in that circle and that circle.

We could also play something on the outside of the circles.

And that means it would not belong to either of those circles.

So that's inside one of the circles.

That's inside the other circle.

That would be both where they crossover and that's on the outside which means it wouldn't belong to either circles.

So here's an example.

I want to classify the diet of different organisms. Maybe they eat plants, maybe they eat animals, maybe they eat both.

And that would be the cross section in the middle.

I wonder what about on the outside? That would mean they don't eat plants or animals.

Let's think about this little human.

She eats both animals and plants because she is an omnivore.

Let's place her in our Venn diagram.

Do you think she should stay on the outside? Do you think she only eats plants? Do you think she only eats animals? Or do you think she should go in this section in the middle that shows that she eats both plants and animals? I want you to point with your finger to the screen based on where you think she should go in the Venn diagram.

Let's see if you're right.

She should go in the middle because she eats those plants and animals, well done.

Let's have another look at a different example.

Now, a shark.

A shock eats other fish.

Does that make it a carnivore, a herbivore, or an omnivore? Can you tell the screen? Well done, it makes it a carnivore.

So let's place it in our Venn diagram.

The shark, should it go in a circle with plants? Should it go in a circle with animals? Or should it go in the middle and shows that it eats both? Well done you know that it's a carnivore, so it only eats animals well done.

Okay, now I'd like you to draw this Venn diagram.

Make sure that you've underlined plants and animals as your titles and make sure you've got a nice cross section in the middle if your circles overlapping.

One thing I'd like to do is draw around something circular.

So if you've got to tin, then you could draw around the tin or you can just do it free freehand.

Pause the video and draw your Venn diagram now.

Okay, what I'm going to ask you to do is the following.

On the screen you can see different organisms. Along the blue rows of the organisms. And along the green rows are their diets.

I would like you to read each organism and what it eats.

For instance, a bear eats both berries and nuts and insects.

That shows me that it's an omnivore.

So now I need you to write it in your Venn diagram.

I'd like you to pause the video and read through all of these organisms and then draw them in the correct place on your Venn diagram.

Pause the video and have a go at that task now.

Well done, pause the video if you need more time because now I'm going to show you the Venn diagram completed that you should also have.

Are you ready? Let's see if you are right.

Okay, so the organisms that only eat plants were snails, goats, and giraffes.

The organisms that only ate animals were bear, leopard, and eagle.

And then the omnivores were robin and a squirrel and they eat both plants and animals.

Now, just before we carry on, I wonder if you can spot the mistake.

I've just been through the answers with you.

And one of them is in the wrong place.

So I wonder if you can see which one.

Where's the one that you had in your Venn diagram that you thought, oh, I thought that was an omnivore.

That's a clue.

Pause the video, and see which of mine you think is mistake now.

Did you spot it? Well done, it was the bear.

I told you that bears were an omnivore.

So I've put it in the wrong place in my Venn diagram.

Where should it be? Can you tell me? Well done, it should be in the middle because bears eat both plants and other animals.

I hope you spotted that.

So well done.

Well done everyone.

You've worked so hard today and Lenny the lion is really impressed with your learning about Venn diagrams to classify different diets.

You are absolutely amazing.

And I can't wait to see you next time for our third lesson on ecosystems. Well done everyone, bye.
