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:

WEATHER AND CLIMATE.

What is climate?
 
Climate is the average weather usually taken over a 30-year time period for a particular region and time period. Climate is not the same as weather, but rather, it is the average pattern of weather for a particular region. Weather describes the short-term state of the atmosphere. 

Climate is a country’s normal weather over a long period of time.  By climate we mean a country’s rain and sunshine, winds, storms and everything else that makes up the weather. 

The weather changes from day to day and even from hour to hour.  It can be sunny in the morning and cold and wet in the afternoon.  The climate changes very slowly over thousands of years. 

We know that the Equator means heat and the Arctic means cold.  Climates are also affected by how close a country is to the sea and by how high a country is. 

What is weather?
The weather is just the state of the atmosphere at any time, including things such as temperature, precipitation, air pressure and cloud cover. Daily changes in the weather are due to winds and storms. Seasonal changes are due to the Earth revolving around the sun.

 There is one basic reason we have weather, and that is the sun. Weather systems start because the sun’s energy heats up some parts of Earth more than others. Most of the time the sun shines most directly on the middle of Earth, with less heating at the north and south poles. Earth is tilted on its axis at exactly the right angle to have seasons, with different parts of Earth being heated more or less during different times of the year. Land heats up faster than water, wetting up temperature differences between oceans and continents. This unequal heating creates variations in temperature and air pressure, winds, and ocean currents.
 

What causes weather?
 
Because the Earth is round and not flat, the Sun's rays don't fall evenly on the land and oceans. The Sun shines more directly near the equator bringing these areas more warmth. However, the polar regions are at such an angle to the Sun that they get little or no sunlight during the winter, causing colder temperatures. These differences in temperature create a restless movement of air and water in great swirling currents to distribute heat energy from the Sun across the planet. When air in one region is warmer than the surrounding air, it becomes less dense and begins to rise, drawing more air in underneath. Elsewhere, cooler denser air sinks, pushing air outward to flow along the surface and complete the cycle.

SEASONS.

We divide up the year into four seasons: spring, summer, autumn, and winter. Each season lasts 3 months with summer being the warmest season, winter being the coldest, and spring and autumn lying in between.

The seasons have a lot of impact on what happens on the earth. In the spring, animals are born and plants come back to life. Summer is hot and is when kids are usually out of school and we take vacations to the beach. Often crops are harvested at the end of the summer. In autumn the leaves change colors and fall off the trees and school starts again. Winter is cold and it snows in many places. Some animals, like bears, hibernate in the winter while other animals, like birds, migrate to warmer climates.

Seasons are caused because of the Earth's changing relationship to the Sun. The Earth travels around the Sun, called an orbit, once a year or every 365 days. As the Earth orbits the Sun the amount of sunlight each place on the planet gets every day changes slightly. This change causes the seasons.
