Students are introduced to the concept of engineering biological organisms and studying their growth to be able to identify periods of fast and slow growth. They learn that bacteria are found everywhere, including on the surfaces of our hands. Student groups study three different conditions under which bacteria are found and compare the growth of the individual bacteria from each source. In addition to monitoring the quantity of bacteria from differ conditions, they record the growth of bacteria over time, which is an excellent tool to study binary fission and the reproduction of unicellular organisms.

To gain a better understanding of the roles and functions of components of the human respiratory system and our need for clean air, students construct model lungs that include a diaphragm and chest cavity. They see how air moving in and out of the lungs coincides with diaphragm movement. Then student teams design and build a prototype face mask pollution filter. They use their model lungs to evaluate their prototypes to design requirements.

Through discussion and hands-on experimentation, students learn about the geological (ancient) carbon cycle. They investigate the role of dinosaurs in the carbon cycle and the eventual storage of carbon in the form of chalk. Students discover how the carbon cycle has been occurring for millions of years and is necessary for life on Earth. Finally, they may extend their knowledge to the concept of global warming and how engineers are working to understand the carbon cycle and reduce harmful CO2 emissions.

Students work together in small groups, while competing with other teams, to explore the engineering design process through a tower building challenge. They are given a set of design constraints and then conduct online research to learn basic tower-building concepts. During a two-day process and using only tape and plastic drinking straws, teams design and build the strongest possible structure. They refine their designs, incorporating information learned from testing and competing teams, to create stronger straw towers using fewer resources (fewer straws). They calculate strength-to-weight ratios to determine the winning design.

Music - Educated Man by Max McFerren

In this activity, students reinforce their understanding of compound machines by building a catapult. This compound machine consists of a lever and a wheel-and-axel. Catapults have been designed by engineers for a variety of purposes — from lifting boulders into the air for warfare to human beings for entertainment; the projectiles in this activity are grapes for a magic act. Given the building materials, students design and build their catapult to launch a grape a certain distance.

In this hands-on activity, students explore the phenomenon of static electricity by engaging in the science and engineering practices of asking questions and planning and carrying out investigations. Students enact a “human diagram” to model the Bohr model of an atom. Then, in pairs, they charge a comb (on hair) and use it to attract an O-shaped piece of cereal and then watch the cereal jump away when it touches the comb. They do the same with Styrofoam pellets, observing them pulling towards a charged comb, then leaping back to the table. Through these investigations, students explore the disciplinary core ideas of electric and magnetic forces, the crosscutting concept of cause and effect, and they make sense of static electricity and what’s going on at the atomic level.

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.

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!

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?

Educational Videos and songs for Kids. Today we’re going to learn about amphibians!

Hello everybody! 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?
