The Solar System is the gravitationally bound system of the Sun and the objects that orbit it, either directly or indirectly. Of the objects that orbit the Sun directly, the largest are the eight planets, with the remainder being smaller objects, the dwarf planets, and small Solar System bodies.
Saturn is known most for its rings.
Galileo Galilei first thought it was an object with three parts: a planet and two large moons on either side.
Not knowing he was seeing a planet with rings, the stumped astronomer entered a small drawing — a symbol with one large circle and two smaller ones — in his notebook.
The rings are made of ice and rock and scientists are not yet sure how they formed. The gaseous planet is mostly hydrogen and helium.

A planet's day is the time it takes the planet to rotate or spin once on its axis.
Write down Saturn's day measured in Earth days.
Neptune is about the size of Uranus and is known for supersonic strong winds.
Neptune is far out and cold.
The planet is more than 30 times as far from the sun as Earth.
Neptune was the first planet predicted to exist by using math, before it was visually detected. Neptune is about 17 times as massive as Earth and has a rocky core.
Neptune has thirteen moons that we know of and one more waiting for confirmation.
The largest moon is slightly smaller than Earth's Moon and has active volcanoes which erupt like geysers and eject nitrogen frost over the surface.
Name this moon and at least 4 others.
It was once considered a planet but in August 2006 the International Astronomical Union (IAU) downgraded the status of Pluto to that of “dwarf planet.”
Pluto is unlike other planets in many respects. It is smaller than Earth's moon; its orbit is highly elliptical.
It's a cold, rocky world with a tenuous atmosphere. Pluto is a very active ice world that's covered in glaciers, mountains of ice water, icy dunes, and possibly even cryovolcanoes that erupt icy lava made of water, methane or ammonia.
The dwarf planet Pluto has five moons.
Name these moons.

Mars is a cold, desert-like place covered in dust. This dust is made of iron oxides, giving the planet its iconic red hue.
Mars shares similarities with Earth: It is rocky, has mountains, valleys and canyons, and storm systems ranging from localized tornado-like dust devils to planet-engulfing dust storms.

Venus is Earth's twin in size and has no moons.
Its surface has various mountains and volcanoes. Because of its thick, toxic atmosphere that's made of sulfuric acid clouds, Venus is an extreme example of the greenhouse effect. The average temperature on Venus' surface is 900 F (465 C).
Venus spins slowly from east to west, the opposite direction to most of the other planets.
The Greeks believed Venus was two different objects — one in the morning sky and another in the evening. Because it is often brighter than any other object in the sky, Venus has generated many UFO reports.

Casas conjunto:
Son un conjunto de sistemas capaces de automatizar una vivienda o edificación de cualquier tipo, aportando servicios de gestión energética, seguridad, bienestar y comunicación, y que pueden estar integrados por medio de redes interiores y exteriores de comunicación, cableadas o inalámbricas, y cuyo control goza de cierta ubicuidad, desde dentro y fuera del hogar.
E-Salud:Es la práctica de cuidados sanitarios apoyada en tecnologías de la información y las comunicaciones.
Tele trabajo: Permite trabajar en un lugar diferente a la oficina,realizando el trabajo en un lugar alejado de las oficinas centrales, a través de las nuevas tecnologías.
E-Administración:
Hace referencia a la incorporación
de las tecnologías de la información y las comunicaciones en las administraciones públicas en dos vertientes: Por un lado,transformar las oficinas tradicionales, convirtiendo los procesos en papel con el fin de crear una oficina sin papeles.Y por otro,habilitar la vía electrónica como un nuevo medio para la relación con el ciudadano y empresas,para mejorar la productividad y simplificación de los diferentes procesos del día a día que se dan en las diferentes organizaciones.

1- Inmigrantes digitales.
Son aquellos que nacieron en el siglo pasado y tienen que aprender a usar las nuevas herramientas que sustituyen a las analógicas que conocían.
Mercury is the smallest, only a little bit larger than Earth's moon. Mercury has no moon.
It experiences dramatic changes in its day and night temperatures: Day temperatures can reach a scorching 840 F (450 C), which is hot enough to melt lead. Meanwhile, on the night side, temperatures drop to minus 290 F (minus 180 C).
It also has a very thin atmosphere of oxygen, sodium, hydrogen, helium, and potassium and can't break-up incoming meteors, so its surface is pockmarked with craters, just like the moon.

Our Solar System has eight “official” planets which orbit the Sun.
Each planet is at a different distance from the sun. Name its position.
