Did you know that the biggest shark that has ever existed was the megalodon?
This gigantic beast had a length of 20 meters and weighed 20 tones! The megalodon lived nearly 20 million years ago and disappeared 2 million years ago. It is considered as one of the most powerful predators of history of the vertebrates and their favorite prey where sea mammals such as whales or dolphins. It is a shame that the megalodon has disappeared but to be honest, it would have been really scary. By the way, did you know that its name originated from Latin and it means ‘Big tooth’?

Did you know that sharks can have thousandths and thousandths of teeth in their life time?
Sharks have their denture distributed in layers. when a tooth breaks, immediately, it is replaced by the layers above.
In general sharks have between 5 and 15 lines of teeth, although the first line is the most important, and it is what they usually eat their prey with. Many scientists have assured us that sharks can have up to 30 million teeth during their life

Did you know that sharks don’t stop swimming, not even for when they need to sleep?
This is because of wo reasons. The first is because of their breathing. Whilst sharks swim, they maintain their mouth open, this way the water that contains a lot of oxygen, passes through their gills and absorbs the oxygen to be able to breath. The second reason is that, differently from all fish, sharks don’t have a swim bladder a kind of internal float that fills with air and allows them to float even though they are still. It sounds weird but it is true, if a shark stops swimming it will fall to the bottom of the ocean and drown. Although the sleeping fish is eaten by the shark…..

Hi Children, in this educational video we are going to learn another interesting animal, the chameleon, a multi-coloured reptile.
The chameleon is one of nature’s most curious reptiles, its capable of changing colour to camouflage, or to say, it can change its colour to match that of its surroundings, so no predators can see it… Look, look, try to find it…
The chameleon, like all reptiles, has a body that is completely covered in hard scales that protect him from its enemies, but they have a characteristic that makes them very special in comparison to other reptiles, do you know which one it is?
As you have discovered by looking at the images, chameleon’s eyes are very special. They are cone shaped and in the centre they have a hole where the pupil peeks out. The cone shape allows them to easily rotate their eyes completely in any direction. They can also move each eye independently, and that is why they have a 360 view, which is to say they can see everything that is happening around them without moving their head. But everything good that they have in their sight is bad in their hearing, why though? Why do you think that is?

As you can see they don’t have any ears and its believed they are deaf.
As we have already said the fundamental characteristic a chameleon has is that it can change its skin colour to adapt to its surrounding. However the colour change also depends on its emotional state… if they are angry… if they are scared or in love.
Another characteristic that surprises everyone is their way of hunting. Chameleons, like crocodiles, snakes and the majority of reptiles are carnivorous… which is why they need to hunt to survive.
The chameleons hunt their pray with their tongs. Their tongue is very long and can be deployed very rapidly. Its tip is sticky and when it touches its prey it sticks to it, making it very easy to then eat them. Chameleons feed mainly on insects although sometimes they can eat in small mammals or birds.

The truth is that chameleons are very extraordinary animals, don’t you think?

Hello Happy friends!
Are you ready to learn?

I’m Sarah, and Today, we’re going to learn a little more about the seasons, and to do this, we’re going to learn about the hemispheres.
-

We all know, that there are four seasons in a year, spring, summer, autumn and winter. And that each one of them has different weather conditions.
-

In winter, it’s very cold
In spring, temperatures start to rise, and of course, flowers start to blossom.
In summer, it’s usually extremely hot
And, in autumn, temperatures start to decrease, and leaves start falling from trees.
-

But… Did you know that the seasons don’t happen at the same time all over the world?
Nope! they don’t, so let’s find out why!
-

Planet Earth, has an axis, an imaginary line, where the earth spins around itself, in a rotational movement.
-
This axis is not up straight, it’s actually leaning, and depending on the month of the year, there are areas that receive more heat than others.
-

Our planet is also divided into two parts, separated by an imaginary line called equator.
This line, divides the earth into two hemispheres: the Northern Hemisphere, and the Southern Hemisphere.
-
Now, let’s see how our planet moves around the sun.
It’s what we call a translation movement.
-
As you can see, the sun heats the Earth, but not equally around the whole world.
Let’s stop the planet. Stop!

In this position, the northern hemisphere has more sun rays, because of the axis inclination.
And that means… We’re in summer! And meanwhile, in the southern hemisphere it’s winter.
buff I prefer summer!
-

But, what happens if the Earth rotates on the other side of the sun?
Well, there would be more rays in the southern hemisphere, meaning that in the northern hemisphere, it’s winter, and in the southern hemisphere, it’s summer.

Easy peasy huh?

Goodbye happy friends! See you next time!

I hope you’re always ready to learn!

Goodbye!

Hello Friends! Welcome to a new Happy Learning video.
Today, we’re going to travel to Ancient Egypt to get to know the mysteries of their pyramids and mummies. But don’t be scared! because they don’t do anything.

As you already know, Ancient Egyptians believed in life after death, that’s why they built the pyramids, which were the pharaohs’ tombs. During their construction, there were thousands of workers for a very long time. Before, we believed that they were built by slaves, but thanks to archaeologist's work, we know that they were built by citizens that worked for salt, wheat or barley. These workers were organised and directed by architects and engineers that made sure everything was calculated and done properly.
Today, we see that pyramids are old, but when they had just been built, they were covered in beautiful white limestone and the tip of the pyramid was golden. I’m sure they were beautiful.

Inside the pyramids, there are tunnels, chambers and secret passageways. And this was where they left the pharaoh’s mummified bodies.

But do you know what a mummy is? A mummy is a person’s or animal’s body that is kept after death. Because Ancient Egyptians believed in life after death, they wanted to preserve their bodies, but it was a very expensive process so only pharaohs and some noblemen were able to do it.
The mummification process took 70 days.
First, the body was washed and all its interior organs, except the heart were removed. Then, the body was filled with linen and covered in salt for about 50 days.
After this time, the body was wrapped in bandages and placed in a luxurious sarcophagus. Thanks to this mummification process, many mummies are in a perfect state today, and have allowed us to learn so many things about Ancient Egypt.
