This document discusses the design and development of a three-dimensional personal learning space (PLE). It provides an overview of PLE models and architectures, examines how PLEs can support quality education, and explores using 3D technologies to create personalized learning environments. Specifically, it analyzes the functional and technical aspects of building a 3D PLE, presents examples of using virtual worlds like Second Life for learning, and proposes a vision for a 3D PLE that would allow users to manage learning activities, interact socially, and access multimedia content in a customized 3D space.

Venus is the second planet from the Sun and the hottest planet in the Solar System, with surface temperatures over 460 degrees Celsius. It rotates slowly in the opposite direction of most planets and takes 243 Earth days to complete a rotation while orbiting the Sun every 262 Earth days. Venus has no moons, and its dense carbon dioxide atmosphere and lack of water mean it cannot support life.
Jupiter is the largest planet in the solar system with a diameter of 142,750 km. It is located 777 million km from the sun and takes 11 years to complete its orbit. Jupiter spins rapidly on its axis every 9.84 hours and is composed primarily of hydrogen and helium gases. It has over 60 moons and is known for the Great Red Spot, a massive storm that has raged for over 300 years.
Saturn is the second largest planet in the solar system after Jupiter, with a diameter of 142,750 km. It takes 29 and a half years to orbit the Sun and rotates on its axis every 10 hours. Saturn has at least 150 moons and moonlets, and is known for its prominent ring system that orbits at different speeds.
Uranus is the seventh planet from the Sun and the third largest planet in our solar system. It is a gas giant with a blue-green color, two rings, and 27 moons. Uranus takes 84 years to complete one orbit around the Sun and rotates once every 17.9 hours on its axis.
THE EARTH by Neus, Jaume, Alex and Judithaeriudavets
The Earth is the third planet from the Sun and is 149.6 million km away. It has unique characteristics among planets like being the only one with liquid water and life, having one large moon, taking 365 days to orbit the Sun, and rotating on its axis every 24 hours.
THE EARTH by Júlia S., Abril, Jack and Borjaaeriudavets
The Earth takes 365 days to complete its orbit around the sun and rotates once every 24 hours. It has an average temperature of 14-15 degrees Celsius and is 12,756 km in diameter. The Earth is unique in our solar system for supporting life and having liquid water, an atmosphere containing 21% oxygen, and a large moon.
Mercury is the closest planet to the Sun, located 58 million kilometers away. It has a diameter of 4,878 km and orbits the Sun every 88 days, taking 59 days to complete a rotation. Mercury has no atmosphere or natural satellites, its surface is cratered and dry, and it cannot support life due to extreme temperature variations between day and night sides.
NEPTUNE BY Jordi, Julen, Núria and Miriam aeriudavets
Neptune is the 8th planet from the sun and the third largest in the solar system with a diameter of 47,150 kilometers. It is a large gas giant with a blue hydrogen-methane atmosphere and faint rings that orbits the sun every 165 years while being covered in thin wispy white clouds.
The document provides information on the Shand & Jurs 94210 Emergency Vent and Manhole Cover. It describes the product's key features such as easy installation and handling, no required gasket replacement or unbolting for inspection, and materials of construction including aluminum, steel, and stainless steel. It also provides specifications on dimensions, pressure settings, materials of construction and an ordering guide for the emergency vent and manhole cover.
Uranus is the 7th planet from the sun located approximately 2.87 billion km away. It is the smallest of the four outer planets. Uranus has 13 rings, takes 17 hours to rotate and 84 years to complete one orbit around the sun. It has 27 moons and an extremely cold surface temperature of -197 degrees Celsius, earning it the name "ice giant".
Saturn is the sixth planet from the Sun and is 1426 million kilometers away. It is the second largest planet in the Solar System with a diameter of 142,750 kilometers. Saturn takes 29 1/2 years to orbit the Sun and has at least 31 moons, being surrounded by prominent rings that are composed primarily of ice particles and dust.
Mars is the fourth planet from the Sun and is nicknamed the "Red Planet" due to the iron oxide prevalent on its surface. It orbits the Sun every 687 Earth days and has a diameter of 6,800 km, turning once every day. Mars has two moons, seasonal changes in temperature and climate, and geographic features including polar ice caps, mountains, craters and caverns.
Neptune is the eighth and farthest planet from the sun. It is a gas giant similar to Uranus, with a diameter of 49,528 kilometers. Neptune has 13 moons and orbits the sun every 165 years while rotating on its axis every 19 hours.
MERCURY by Toni Miquel, Marta and Miquelaeriudavets
Mercury is the planet closest to the Sun, orbiting it every 88 days. It has extreme temperature variations between its day and night sides, reaching 400 Celsius on the sunny side but plunging to -200 Celsius on the dark side, due to its lack of an atmosphere. Mercury is a small planet with a diameter of only 4,878 kilometers, has no moons, and its cratered surface is too hot on one side and too cold on the other to support any life.
Mars is the fourth planet from the sun and is often called the red planet. It has polar ice caps and seasons, with temperatures dropping as low as -82 degrees Celsius in the winter due to its thin atmosphere. Mars has two moons named Phobos and Deimos, mountains, craters, and caverns, and completes one orbit around the sun every 1 year and 320 days as it spins on its axis every 24 hours and 39 minutes.
Jupiter is the largest planet in our solar system, with a diameter so large that over 1300 Earths could fit inside it. As a gas giant, Jupiter is composed primarily of hydrogen and helium and takes almost 12 months to complete one orbit of the Sun. Notable features include the Big Red Spot, a massive storm larger than Earth, and 67 known moons such as Io, Europa, Ganymede and Callisto.
Venus is the second planet from the Sun and the brightest object in the night sky. It has no moons and orbits the Sun every 243 Earth days. The surface of Venus is extremely hot due to its dense carbon dioxide atmosphere, with surface temperatures reaching over 460 degrees Celsius.
