LIVING BEINGS.




Look around you. What do you see? A classmate, a brother or sister? Look out the window, or go for a walk. You will see trees, grass, plants, dogs, cats, bugs, and many other forms of life. 

Now, think about this. Life extends much further than what you can see. Everywhere around you, all over your keyboard, the computer monitor, your desk, the walls, the floor, the ceiling, your clothes, and even your skin, you can find billions and billions of tiny microscopic lifeforms.  



Life is all around us. From many kilometers (miles) into the atmosphere, to many meters (feet) beneath the surface of the Earth, life is everywhere. What is this stuff we call life? What are some things that all life forms have in common?


Living Things Are Made of Cell.

All living things are made up of cells. These cells are the basic building blocks of life. As an example, have you ever seen a sandcastle? At a distance, the sandcastle looks like a smooth brown building. As you get closer to the sandcastle, you can begin to see that it is not one smooth building, but instead that it is made up of millions of tiny grains of sand.

Looking at an elephant, you might see what looks like a smooth gray animal. And it is true that this is what you are seeing. However, just like the sandcastle, if you could get close enough, and if your eyes were powerful enough, you would realize that what looks like a smooth gray surface, is really made up of many billions of smaller objects called cells. 

Cells are tiny units of living materials separated by a cellular wall, or barrier. These cells are so small, that they can only be seen with a powerful tool known as a microscope. Cells make up every part of a living thing. Your skin, your hair, fingernails, blood, bones, nerves, and muscles are all made up of cells. These cells work together to keep the lifeform alive.  

Many lifeforms can move. 

Just like you, they might move to find food, to find shelter, to avoid danger, or in response to their environment. Animals move in many different ways. They might use fins to push them through the water, wings to help them fly, paws and tails to help them move on land.


Plants also move. They of course cannot move as well as animals, but many plants move their stems to face the Sun, open and close flowers, and more. Some carnivorous plants even move to trap prey.  


Living Things Grow.


What would you like to be when you grow up? Well, first you must eat a lot of food and get your rest. These things are necessary for your body to grow. Like you, other living things also grow. Almost all living things start their lives as smaller infant-like creatures. Over a period of time, they grow and develop into adults. Some lifeforms, such as frogs, start their life in a completely different form, and then change dramatically as they grow. A frog begins its life as a tadpole, then turns into an adult frog. A butterfly starts its life as a caterpillar before maturing into a full grown beautiful butterfly.
Living Things Reproduce.

A very important part of the life of living things is the ability and opportunity to reproduce, to create offspring. Reproduction is the process of one or more living things creating another living thing. Your parents created you. A mother and father dog reproduce, creating puppies. By reproducing, living things are able to pass on their characteristics to another generation.
Living Things Die.

Something that is definitely unique to living things is that they die.
Anything that is alive will eventually die. The period of time that something is expected to live is called the living thing‘s “lifespan.” The lifespan of living things can vary significantly.

What Is The Solar System? 

The Solar System formed around 4.6 billion years ago.
The Solar System is full of planets, moons, asteroids, comets, minor planets, and many other exciting objects.

The Solar System is made up of all the planets that orbit our Sun. Everything in the Solar System orbits or revolves around the Sun.
It is true that there are only eight planets. However, the Solar System is made up of over 100 worlds that are every bit as fascinating. Some of these minor planets, and moons are actually larger than the planet Mercury! 


There are eight planets in the Solar System. The four inner planets are Mercury, Venus, Earth and Mars while the four outer planets are Jupiter, Saturn, Uranus and Neptune.
The inner planets (also known as terrestrial planets) are smaller and made mostly of rock and metal.
The outer planets (also known as gas giants) are much larger and made mostly of hydrogen, helium and other gases.






THE EARTH’S ROTATION AND ORBIT


The Earth rotates on its axis. The Earth’s axis is tilted.
This rotation is why we have day and night.
It takes twenty-four hours to complete one rotation.
The Sun shines on one half of the Earth, so it’s day on the half of the Earth that faces the Sun and it’s night on the half of the Earth that faces away from the Sun.
When the Earth orbits the Sun, one hemisphere receives more light and heat than the other. This is why there are different climates and seasons on Earth.







THE EARTH’S MOON.


The moon is the Earth’s only natural satellite.
The moon takes about twenty-eight days to orbit the Earth and it rotates on its axis at the same time.
The bright part of the moon is the part that the Sun is shining on.
The moon reflects this light from the Sun and this is what we see from the Earth.
The moon looks as if it’s changing shape and we call these shapes the phases of the moon.
The six main phases of the moon are:

El algoritmo ABN.

En esta entrada voy a explicar un poco en qué consiste el método ABN. 

Este método surgió aproximadamente hace menos de diez años, y desde entonces ha ido divulgándose entre los docentes. Fue creado en por Jaime Martínez Montero, inspector de educación y maestro y doctor en Filosofía y Ciencias de la Educación.


En nuestro sistema educativo tenemos un algoritmo de cálculo que lleva tiempo implantado y del que no se ha cuestionado su validez o su eficacia, sino que únicamente se transmite a los alumnos, que aprenden a realizar las operaciones sencillas (sumas, restas...) a base de su repetición, es decir, de realizar más y más cuentas, llegando a ser un poco monótono y aburrido.  Por estas razones este profesor decidió crear este nuevo método, ya que, según sus propias palabras,
"Es posible calcular de manera más motivadora, más fácil, más conectada con el pensamiento de los niños, más adaptada a sus futuras necesidades. En definitiva, el modo más eficaz para que los alumnos alcancen competencia matemática".
Para comprenderlo, es necesario establecer de donde provienen sus siglas: "A" viene de Abiertos, ya que el alumno que resuelve una cuenta mediante este método puede elegir una forma particular de solucionarla, la que le resulte más fácil y comprensible; en cambio, en el algoritmo tradicional sólo pueden solventarla a través de un único camino ya marcado por las directrices del algoritmo. "BN" derivan de Basados en Números. En este aspecto es igual que el tradicional, pero con un tratamiento diferente y lleno de significación para el alumnado. En el método tradicional para realizar cuentas (con independencia del número de cifras que tengan cada número) se actúa sobre cada cifra por separado y se les aplica el mismo tratamiento. Es decir, no importa el lugar que ocupe un cifra, ya sea en las decenas , unidades de millar, .. el proceso es siempre el mismo para cada cifra, con lo cual se pierde el sentido que tienen esas decenas, centenas… En el método del algoritmo ABN, el alumno/a trabaja con unidades, decenas, centenas, componiéndolas y descomponiéndolas libremente, para llegar a la solución a través de los pasos que le permita su dominio del cálculo.



Características del método:

Según los expertos, estas son las características que lo definen: - Mejoran el cálculo mental y las estimaciones. - El alumnado aprende más rápido y mejor. - Aumenta la capacidad de resolución de problemas.
- Desaparecen ciertas dificultades y trabas del algoritmo tradicional como las llevadas en sumas y restas, la colocación de las cifras, el orden de los términos, las dificultades con los ceros intermedios en la multiplicación, o en la división el cero al cociente intermedio o al final...

- El alumno adapta las operaciones a su nivel de dominio en el cálculo y no es él quien se adapta a la operación.

- Mejora la actitud de los alumnos hacia las matemáticas.

- Afianzas la confianza en el cálculo.
 Aqui os dejo algunos ejemplos de cómo se realizarían las principales operaciones con el algoritmo:
