They can be as huge as these whales,or as tiny as this cute little balancing mouse. They can be noisy like this howler monkey, or quiet like this hedgehog with its sharp, pointy spines. Even though they’re amazingly diverse, all mammals have a number of common characteristics you should know about, so you can recognize and differentiate them. All mammals are viviparous, they are born from their mothers’ womb. In their early stages of life, they feed on milk, which they get from their mothers' breasts where the mammary glands are. And that’s why they’re called mammals. And when they’re little, they’re so cute, aren’t they? Mammals reproduce by internal fertilization when a sperm cell and an egg join inside the female. As you can see, they have teeth inside their mouths, and lips around them so they can eat and suck milk. Most mammals’ bodies are covered with hair, and all mammals breathe with their lungs, even if they live in the sea. Look at these dolphins coming to the surface for air. The body temperature of mammals doesn’t depend on whether it’s cold or hot outside, because they can maintain their own internal temperature. Almost all mammals are terrestrial, like camels, and jaguars. Some live in the sea and are called Marine mammals,like these dolphins,and these seals,There's even a flying mammal, bats are the only mammal that flies. Mammals have four limbs, which vary depending on where they live. Land mammals have legs,so they can walk,and run when they need to,and Jump.,and sometimes even climb. Marine mammals have fins so they can swim very fast... And flying mammals have wings so they can fly through the sky... Do you know which is the most wonderful mammal that lives on Earth?Human beings! People are mammals too... How mammals feed Depending on what they eat, mammals can be classified into different groups. Herbivores only eat plants and their teeth are especially designed for grinding. Horses, sheep and llamas are herbivorous mammals. Some very special herbivores are called ruminants. They swallow their food almost without chewing it, and some of it is digested normally, but some of it is stored in their stomach, and when they want to, they regurgitate it into their mouth to digest it again. Cows, giraffes and goats are ruminants. Carne means skin or meat in Latin, and that’s what carnivores eat: the flesh of other animals. Their teeth are large and sharp for hunting and tearing at their food. Carnivores that eat insects and other invertebrates are called insectivores,like these anteaters. Omnivorous mammals feed on both meat and plants. Bears, monkeys and humans are omnivores: we can eat a tasty burger with lettuce and tomato. So, let's remember, Mammals are viviparous, and in their early stages of life they feed on milk from their mother’s breasts,They have lips and breathe with their lungs,Their body temperature does not depend on the environment they are in, and depending on their food sources, they may be herbivores, carnivores or omnivores.

Hello friends, and welcome to a new Happy Learning video. Today we are going to talk about one of the most famous of all the fish in the ocean, the one who scars us the most, presenting...the shark. First of all, what we must know about sharks is that they are fish and like all fish, they have gills which allow them to breath under water. The fish´s body is covered by scales and in the case of the shark, the scales are so hard and rough that a long time ago the sharks skin was used as sand paper. There are many different types of sharks, almost 400, some measuring just 15cm , which is as small as a Mobil phone, and others, such as the whale shark, reaches up to 14 meters, which is a lot longer than many of the large trucks you can see on the road. There are also very odd looking sharks such as the hammer head. Sharks are carnivores and are characterized for their excellent hunting skills. When hunting, they use their fantastic sense of smell as well as their strong jaws full of sharp pointed teeth. As the sharks use their teeth so frequently, they tend to fall out easily but it is not a problem as they grow back again. During a shark´s life time they could even have up to 30,000 teeth. That's a lot of teeth! Another interesting and curious fact about the shark is that they can go up to 6 weeks without eating, that's a month and a half! It is for is reason that they get really hungry. Sharks are cartilaginous fish, meaning their skeleton is made of cartilage instead of bone. The most famous sharks of all, is without a doubt the great white shark. The great white live in warm waters, and can weigh between 700 and 1.100 kilos, Their body is so big and robust...they are a bit scary, don't you think? The whale shark is the biggest of all of them, not only the biggest of the shark family but the biggest of all the fish in the sea. It weighs 20 tons, meaning 20 thousand kilos and is also known as having the longest life span, living between 70 and 100 years. Well it is also true that we do leave them to live in peace. Though did you know that sharks are in great danger of being extinct? There are many different kinds of sharks which are about to disappear and this is causing the whole ocean to be at risk. The oceans and seas are healthy, and they need to have enough sharks to ensure the balance between the various different species. Without this balance, we have no idea what could happen, but nothing good, I am sure. For this reason it is so important to take care of them. We should not throw rubbish and plastic into the sea and we must always defend nature by picking up whatever object could harm it. Because if we defend nature, we are also defending life, and all living creatures in it, including us humans. Well now you have learnt a few more important facts about these amazing fish, the sharks. Aren't they just so fascinating? So it's goodbye for now friends and don't forget to subscribe to Happy Learning.

Today we’re going to look at a truly amazing group of vertebrates... When they’re born they usually live in water... but when they grow up and become adults they spend most of their time on land. We present - the Amphibians! All amphibians have some common characteristics that you should know about so you can recognize and differentiate them. Amphibians have thin, bare skin, with no hairs and scales to protect them. Most have four legs and a membrane between their toes that allows them to move much better in the water. Amphibians are oviparous, but they don’t incubate their eggs after laying them... they abandon them and don’t care for their young. Not very good parents, huh? When they hatch, they’re small larvae and live in water. Slowly... very slowly... their bodies go through a process called metamorphosis. During this process, the body of the amphibian... changes... their front and rear legs, their limbs, grow... and their heads and their bodies develop, so they finally look like their parents. In the early stages of their lives... amphibians breathe through gills, but when they grow up and become adults... they breathe with their lungs. The problem is, their lungs are very small, and cannot get all the oxygen they need to live. But nature is very clever... and has solved this problem by allowing them to breathe and get the oxygen they need... through their skin. That’s why they need to be near water - to keep their skin wet. In the early stages of their life, some amphibians are herbivores, but when they grow up... most become carnivores. So they need to hunt... Some have a long, sticky tongue they shoot out to capture prey. Aren’t amphibians fascinating? And also a bit strange?! So let’s remember the most important characteristics... Amphibians are vertebrates; they’re oviparous; in the early stages of their life they live in water as larvae, but slowly they change until they look just like their parents. This process of change is called metamorphosis. Amphibians are carnivores, so they have to hunt to eat; they have thin, smooth skin, and breathe through their skin and with their lungs. Amphibians are so interesting, aren’t they?

All the invertebrates are oviparous, and we classify them in 6 big groups: Sponges, jellyfish, corals, worms, mollusks, echinoderms and arthropods The sponges are aquatic animals, that are sac shaped and their body is full of pores. It is very easy to remember this group because many times we use them in the shower for our personal hygiene. Yes, many of the sponges we use in the shower are invertebrate animals. The jellyfish are invertebrate animals that live in the ocean. Their bodies are gelatinous and have tentacles. The truth is that when they appear in the beach it is very annoying because their tentacles have small venomous stingers that produce very unpleasant bites. Corals are tiny marine animals that produce limestone residue, which give rise to beautiful shapes. Do you know this animal? Exactly, it’s a worm. Worms are soft and long invertebrate animals that move by dragging their body in the ground, because they have no feet. They can be aquatic or terrestrial. There are some worms that can be harmful and that is why we must be careful with them. Can you see this snail? Well snails form part of the mollusk group. Mollusks have a soft body, without legs and can also be aquatic or terrestrial. Some, like this snail, this clam and mussels, protect their soft body with shells, but there are other mollusks that don’t have a shell to protect themselves like slugs or octopuses. The echinoderms are exclusively aquatic animals. Their bodies have calcareous plates that form a shell. Some echinoderms are balloon shaped and are covered in spikes that they use to defend themselves, like sea urchins. Others are star shaped, and are of course called starfish. The arthropods are the most abundant animals on the earth. Of every 100 animals that exist, 80 are arthropods. These invertebrate animals have their body covered by an external skeleton called a cuticle. The most common way to classify the arthropods is by the number of legs they have. This way we can classify them in four big groups. Arthropods with 6 legs. In this group insects like ants and flies are present. Arthropods with 8 legs, where for example the arachnids like spiders and scorpions are. Arthropods with 10 legs include the crustaceans, like crabs and lobster. Arthropods with more than 10 legs like this centipede that as you can see has much more than 100 legs are called myriapods. Well now you know a bit more about the invertebrates.

They are so diverse, and there are so many colors and shapes, it's fun to learn about them. For example, this tiny little hummingbird doesn’t look anything like this huge ostrich. And these penguins don’t look much like this peacock with its large fan-shaped tail. Well, they may not look alike, but they’re all birds, and have many things in common. Birds are oviparous... which as you know, means that they reproduce by laying eggs. The females lay the eggs in nests, in the rocks... or on the ground... And with the heat of their bodies, they incubate the eggs until the little chicks hatch. Birds don’t have teeth, they have beaks or bills... And these can be very different, depending on what that species of bird feeds on. They breathe with their lungs, that are connected to... bags full of air... called air sacs... and these help birds to fly. Also, nature, which is very clever, has made their bones hollow, so they weigh very little, and because of this it’s much easier for them to fly. The skin of birds is covered with feathers: these protect them from the cold and heat. Birds have four limbs, the back ones are legs... and the front ones are wings. Together, the wings and feathers are essential for them to be able to fly... and in some cases... so they can swim. Birds are terrestrial and most of them can fly. Can you think of any birds that can’t fly? That’s right!!! Penguins and ostriches are two species of birds that cannot fly. Birds have four types of feathers: those that cover the whole body; flight feathers in the wings that help them to fly; down feathers, which cover the chest and belly and maintain the body at a constant temperature; and tail feathers that help guide the birds’ body like a rudder on a boat. Birds can be classified into several groups, according to what they eat: herbivores feed on plants and grasses – their beaks are short and strong, and can crush seeds and grains. When they only eat grains, they are called granivores. Carnivorous birds hunt and eat other animals, using their strong, curved beaks. Within the group of carnivores there are insectivores, that only eat insects, and piscivores that only feed on fish. These birds have pointed beaks that are long and sharp to help them catch the fish. Remember - birds that eat fish are called piscivorous. The last group - omnivorous birds - includes pigeons and hens, and they eat almost anything. So remember: birds are oviparous, which means they reproduce by laying eggs; their mouths are beaks or bills and they breathe with their lungs; their skin is covered with feathers; and depending on the food they eat, they can be herbivorous... carnivorous... or omnivorous. So, now you know a lot more about birds. Goodbye, everybody, and don’t forget to subscribe to Happy Learning!!!

Reptiles are vertebrate animals which are characterized by their special way of moving: many move by dragging their tummy, or abdomen, on or close to the ground; their name, in Latin, means just that: reptar mean to crawl or slither. Many are terrestrial, but there are also some that live in water. All reptiles have a number of characteristics we should know about so we can recognize them. Reptiles are cold-blooded animals that breathe with their lungs. They are oviparous, that is they reproduce by eggs; when the eggs develop and hatch, the babies are just like their parents... but very small. Aren’t they cute? As you can see, reptiles’ skin is covered with strong, tough scales, and some, like tortoises, even have a shell. It looks like he has his house on his back, doesn’t it? As for feeding well, most reptiles are carnivorous... They hunt, like this crocodile which has just eaten this poor rodent; or this cute chameleon, with its long, sticky tongue that catches all kinds of insects... Look, look! As we said already, most reptiles are carnivorous, but some, like this iguana, are herbivorous. There are lots of interesting things you should know about reptiles, such as: most snakes have venom in their fangs... But they’re not as bad as they seem, because they warn us of danger with their bright colors or the sound of their rattles. Chameleons are very curious: they can change color, copying the landscape around them they blend in with the background so no-one can see them, and they become almost invisible. So let’s remember the most important characteristics of reptiles. Reptiles walk by dragging their tummy on or close to the ground; they are oviparous and their body is covered with strong, hard scales... They are vertebrates and are cold-blooded... And remember, they breathe with their lungs. Reptiles really are quite interesting, aren’t they?

Today we’re going to look at vertebrate animals. As you know, we can classify animals in various ways, depending on the characteristics we look at. Today, we’re going to some animals by the internal structure of their bodies. According to this feature, we can classify them into... Vertebrate Animals, which have an internal skeleton, that means bones.... And Invertebrate Animals... like this worm, which has no backbone... in fact, no bones at all. All vertebrate animals have an internal skeleton made up of... bones. Bones are very strong, and give bodies their shape, they hold it up, nice and straight. The spine – the backbone – is made of a series of articulated pieces of bone, called the vertebrae, which allow the body to move in a certain way, and flexible. Vertebrate animals’ bodies are divided into the head... the torso... and the limbs ... Yes ...... the head ... the body... and the arms and legs. Some vertebrates are aquatic... like these fish ... Others are terrestrial... like this bear. And other fly... like this eagle. Vertebrates can move in many different ways... walking... jumping... crawling... climbing... and when they have running ... but sometimes it’s not enough. There are also many vertebrate animals that move by flying, like birds and bats. For example, these eagles... which unfortunately for the fox, are much faster than him. Vertebrates are classified into five groups: Fish... Reptiles... Amphibians ... Birds... and Mammals... like this big howler monkey. Now let's remember the most important things we’ve learnt about vertebrate animals. Vertebrate animals can be classified into 5 groups: Fish... reptiles... amphibians, birds... and mammals. Vertebrates have internal skeleton made of bones... The body of this kind of animal is divided into head, torso and limbs... They move in many ways: walking, jumping, crawling, flying, climbing and when they need to, running....
Hello friends, and welcome to another new Happy Learning video. Today we will learn about the water cycle. Earth, which is the planet we live on, is known as the Blue planet because as much as 3/4 of the planet's surface is ...water! And water is so very important because without it, there would be no life. Without it, theses sweet little otters wouldn't exist, or theses playful bears, nor this conceited bird, or even us, the human beings. That's why we must look after it. We should conserve our water well and most of all, we must maintain our rivers and oceans clean. Did you know water never stands still, but is always in constant movement, even though at times it doesn't seem like it? This water movement is what is called the Water cycle. Now let's learn more about it. When the sun warms the water on the Earth's surface, it evaporates, converting itself into water vapor or steam and begins its incredible journey flying into the sky, up towards the atmosphere. This first stage of its journey is known as evaporation. When the water converts in vapor, it rises towards the atmosphere, then cools down transforming itself into clouds. This second stage of its journey it called condensation. Once the water has condensated, and turned into a cloud, it continues its amazing journey by being blown by the wind, traveling from one place to another. Clouds are actually tiny little drops of water suspended in the air, but when the clouds grow, they collect more and more water. These water drops then crash into each other and become bigger drops of water. Then at some point, they end up falling to the ground in the form of rain or even snow. This stage of the water cycle is called precipitation. The water which falls to the ground, which precipitates in the form of either rain or snow may land in rivers, or even on the ground to then seep through to subterranean currents of water. All this water must continue its long journey, covering large amounts of distances until it finally reaches the sea. When it arrives at the big blue sea, it will once again begin the process...evaporation, condensation, precipitation. That's why it is called the water cycle, because it forms a never-ending circle. Isn't the water cycle just so incredible? Well that's all for now, until the next video, and don't forget to subscribe to Happy Learning.

Today we are going to learn about… the Moon. The Moon is the only satellite that rotates around our planet and it takes 28 days to completely go around the Earth. But, do we now what a satellite is? A natural satellite is any kind of celestial body that rotates, or actually, orbits around a planet. The Moon is never still, it moves and in two ways. It has a movement of rotation, which means it turns in its own axis, and a movement of translation, that is to say, it rotates around the Earth. The duration of the movement of rotation and translation is 28 days. Because it takes the same amount to rotate on its own axis and to completely go around the Earth, the Moon always shows us the same face. When we observe the Moon along a period of time it appears to change shape. These changes in appearance are called lunar phases and they repeat every 28 days. There are four: full Moon, first quarter, new Moon and last quarter. The Moon phases are produced by two reasons: the movement of the Moon around the Earth and because the Moon reflects light form the sun as a mirror. New Moon In this phase the Moon is passing between the Earth and the Sun. The illuminated face of the Moon is facing the opposite direction to Earth. The dark side ends up facing the Earth, and this is why we cannot see the Moon. First Quarter You can see it approximately one week after the new Moon. One half of the illuminated side faces the Earth. It is called the first quarter because, from the new Moon phase, the zone illuminated by the sun grows every time. Full Moon Approximately a week after the first quarter, we can see the whole Moon illuminated. The Earth is between the Moon and the sun and we can see it fully. Last Quarter The Moon presents its other half face illuminated. The name of the last quarter comes from the fact that the illuminated side becomes smaller and smaller each time A very easy trick to now whether the Moon is in its first or last quarter is the following. If the Moon has the shape of a C, it is in its last quarter and if it has the shape of a D, it is in its first quarter. So now you know, the Moon has 4 phases: New Moon, first quarter, full Moon and last quarter. Know we are going to learn a few facts about the Moon Do you know the distance between the Moon and the Earth? Although it looks as though it is not very far away, the Moon is about 385,000 kilometers from the Earth. Another very interesting fact is that a rocket takes three days to get to the Moon. Its incredible, isn’t it? The first astronaut that stepped on the Moon was Neil Armstrong and this very important accomplishment occurred in the year 1969 aboard the Apollo 11 rocket. The Moon is 4 times smaller than the Earth, but it is very important for the sustainability of life in our planet. The Moon generates tides; Do you now what that is? A tide is the rise and fall of the sea level. They occur every 6 hours approximately. Well now you know a little bit more about the Moon, very interesting, right?

Today we’re going to learn about the Solar System. As you know, the Sun is a star, one of the many stars that form the Milky Way. But for us, it is the most important star shining in the sky. Planets move around the Sun, and so do comets and asteroids. Well, the Sun and everything that revolves around it is what we call the Solar System. The most interesting things that we should know about in the solar system are the Planets. Let’s look at them, starting with the ones closest to the sun, and then getting further away! The closest planet to the Sun is Mercury... then there is Venus... then comes the Earth. Yes, our planet where we live... Then there is Mars... Jupiter, the largest planet... Saturn... Uranus... and then the furthest away is Neptune. ▶SUBSCRIBE TO HAPPY LEARNING! http://bit.ly/HappyLearningTV "Educational Videos and songs for Kids" As you can see, Mercury, Venus, Earth and Mars are closer to the sun and also smaller than Jupiter, Saturn, Uranus and Neptune. One important thing you should know is that the journey that all planets make around the sun is called an orbit. Now, a question: do you know where the days of the week... get their names from...? Well, if we think about it for a minute... the Moon, which is not actually a planet itself, but Earth’s natural satellite... gives it name to Monday... Tuesday, Wednesday, Thursday and Friday come from ancient British gods that were related to the planets Mars, Mercury, Jupiter and Venus... Saturday gets its name from Saturn.... and of course, the Sun itself gives us the name Sunday. So if you remember that there is also Uranus, Neptune and our own Earth, then you know all the names of the eight planets in the solar system. Easy, eh? So, goodbye for now, everyone.
