What are you waiting for? The dolphin, a very friendly mammal

Hello friends, and welcome to a new Happy Learning video. Today we are going to learn about one of the most friendly and fun mammals, presenting the dolphin.

Dolphins are aquatic mammals which live in most seas around the world.

Dolphins have a dorsal fin on the top part of their body and two lateral fins as well as a flat tail called a fluke, which they use to beat the water in an up and down motion, allowing them to swim at great speeds as well as completing agile jumps out of the water.

Did you know that dolphins don't have a nose? They have a beak and they breathe through a hole above their head. Can you see it? well this hole is called the blow hole and they close it every time they go under water so as not to let water come into their lungs.

Dolphins can submerge themselves up to 300 meters deep and can hold their breath for almost 25 minutes!

Do you know how dolphins sleep? It is really curious...because they sleep...in sections. First half of their brain and half of their body goes to sleep and when that part wakes up, the other half goes to sleep. It is for this reason that they sleep with one eye open, always aware of what is going on around them. Like this they are always alert...

Dolphins belong to the cetaceous family, like whales.
The average length of a dolphin is around 4 and a half meters, which is the length of normal car and they weigh about 300 kilos.

For orientation, dolphins use a system called echolocation. The sounds the dolphins emit travels through water until it rebounds off an object found in its path, and sends it back to the dolphin. Now the dolphins can calculate how far away the object is, its size and also its shape.

Dolphins are carnivorous, their main source of food is based on crustaceans, fish, squid and octopus.

Dolphins just like all mammals are viviparous and the gestation of a baby takes 12 months. During the first month of a baby´s life, it feeds on the mother's milk and then the baby is taught how to hunt by other members of its family.
Dolphins are not scared of humans and when they encounter them, they are very friendly. They are really playful and curious animals.
Dolphins tend to live in a group and are extremely intelligent. As they are together in a group they help each other by defending off sharks and orcas by butting them with their strong beak.

But do you know what the dolphin´s biggest problem is? The humans. It is because of humans hunting them and contaminating the waters which is causing many dolphins to die. Many dolphins have been trapped in fishermen's nets or suffocated with plastic bags and rubbish which has been thrown in the sea, but this is a problem happening not just for dolphins but for many other marine species, such as turtles and seals. It is for this reason that it is just so important to look after our seas and oceans and that we should never, ever, ever, throw anything into the water.

If we maintain nature clean, dolphins as well as all other living creatures will be very happy.

Educational video for children that talks about terrestrial and aquatic habitats. A habitat is a place that has the necessary resources for living beings to survive. These resources are light, water, temperature, soil and oxygen. The different characteristics of these resources are what make for different habitats. There are two types of natural habitats: terrestrial and aquatic. Among terrestrial habitats there are deserts, jungles, forests, grasslands and savannas. Aquatic habitats include landscapes such as rivers and lakes, oceans and seas. In aquatic habitats, living things have adapted to living in water.

This video is a very useful and interesting resource for children. It is perfect for teaching about natural habitats. It is an excellent video for primary education.

Educational video for children to learn about the thirteenth of the Sustainable Development Goals (SDGs), climate action. Climate is defined as the weather conditions that characterize a given place. This includes temperature, humidity and wind, among other things. Each year is hotter than the last and the levels of carbon dioxide and other harmful greenhouse gases continue to rise. For these and other reasons, the United Nations has made climate action one of its main sustainable development goals. Climate change is affecting all countries with no exceptions. Sea and ocean levels are rising and weather phenomena are becoming more extreme. We need to be aware of the climate change that our planet is undergoing, and we must try to minimize its effects as much as possible.

This video is a very useful and interesting resource for children. It is perfect for teaching what the Sustainable Development Goals are. It is an excellent video for primary education.

Potential energy is the energy held by an object because of its position relative to other objects, stresses within itself, its electric charge, or other factors.

Common types of potential energy include the gravitational potential energy of an object that depends on its mass and its distance from the center of mass of another object, the elastic potential energy of an extended spring, and the electric potential energy of an electric charge in an electric field. The unit for energy in the International System of Units (SI) is the joule, which has the symbol J.

The term potential energy was introduced by the 19th-century Scottish engineer and physicist William Rankine, although it has links to Greek philosopher Aristotle's concept of potentiality. Potential energy is associated with forces that act on a body in a way that the total work done by these forces on the body depends only on the initial and final positions of the body in space. These forces, that are called conservative forces, can be represented at every point in space by vectors expressed as gradients of a certain scalar function called potential.

Since the work of potential forces acting on a body that moves from a start to an end position is determined only by these two positions, and does not depend on the trajectory of the body, there is a function known as potential that can be evaluated at the two positions to determine this work.

There are various types of potential energy, each associated with a particular type of force. For example, the work of an elastic force is called elastic potential energy; work of the gravitational force is called gravitational potential energy; work of the Coulomb force is called electric potential energy; work of the strong nuclear force or weak nuclear force acting on the baryon charge is called nuclear potential energy; work of intermolecular forces is called intermolecular potential energy. Chemical potential energy, such as the energy stored in fossil fuels, is the work of the Coulomb force during rearrangement of mutual positions of electrons and nuclei in atoms and molecules. Thermal energy usually has two components: the kinetic energy of random motions of particles and the potential energy of their mutual positions.

Potential energy is closely linked with forces. If the work done by a force on a body that moves from A to B does not depend on the path between these points (if the work is done by a conservative force), then the work of this force measured from A assigns a scalar value to every other point in space and defines a scalar potential field. In this case, the force can be defined as the negative of the vector gradient of the potential field.

Gravitational energy is the potential energy associated with gravitational force, as work is required to elevate objects against Earth's gravity. The potential energy due to elevated positions is called gravitational potential energy, and is evidenced by water in an elevated reservoir or kept behind a dam. If an object falls from one point to another point inside a gravitational field, the force of gravity will do positive work on the object, and the gravitational potential energy will decrease by the same amount.

Consider a book placed on top of a table. As the book is raised from the floor to the table, some external force works against the gravitational force. If the book falls back to the floor, the "falling" energy the book receives is provided by the gravitational force. Thus, if the book falls off the table, this potential energy goes to accelerate the mass of the book and is converted into kinetic energy. When the book hits the floor this kinetic energy is converted into heat, deformation, and sound by the impact.

The factors that affect an object's gravitational potential energy are its height relative to some reference point, its mass, and the strength of the gravitational field it is in. Thus, a book lying on a table has less gravitational potential energy than the same book on top of a taller cupboard and less gravitational potential energy than a heavier book lying on the same table. An object at a certain height above the Moon's surface has less gravitational potential energy than at the same height above the Earth's surface because the Moon's gravity is weaker. "Height" in the common sense of the term cannot be used for gravitational potential energy calculations when gravity is not assumed to be a constant. The following sections provide more detail.
