Science students for the contemporary world have just completed group work and oral presentations on different aspects of the universe. The following video shows a trip to the limits of the universe with a detailed itinerary of the various "known structures" presented car warmer through real images and animations.
Students who have completed this activity, car warmer explain a summary of their work in the comments of this post. Follow the recommendations listed by posting comments on this blog post 341 DNA-DNA.
Exhibition on the Big Bang can be described as a giant fireball that exploded in a huge explosion at the beginning of the history of our space-time. The explosion in this area was expanding rapidly, the materials that were, were scattered forming space and as this cooling would formed the first stars and planets and galaxies that . At the same time came the first chemical elements hydrogen and helium and other elements being formed in the interior of stars. History: In 1924, Edwin Hubble calculated that there was a great distance between the nearest spiral nebulae showed that these systems were indeed galaxies. Law Hubble car warmer Constant mathematical said that the galaxies are moving away from each other faster the farther car warmer they are from. For this to happen the matter car warmer had to be concentrated at a point before. Testing the theory: 1) Doppler effect: When a galaxy emits waves while moving, these waves are distorted. If a body wave approaches it is compressed and if it alienates the wave expands. car warmer 2) cosmic background radiation: in 1964, came to Earth radiation of the universe (cosmic) and weak (background), is said to be the echo of the Big Bang that still reaches us. What will happen in the future? 1) Big Rip Theory (large tear): separating the galaxies will slowly until the moment when he began to create black holes and the whole matter to be disturbed car warmer in nothing. 2) Big Crunch Theory: The material reaches its maximum point of expansion, then back together and there will be a new explosion car warmer and so on. This theory is deprecated because it shows that galaxies never stops expanding.

Mars Mars is the fourth planet in the solar system. Also called the red planet because it is the color. It has two moons called Phobos and Deimos. FEATURES: equatorial radius -> Mars (3397 km) Land (6,378 km) Massa -> Mars (6.42 x 1023 kg) Earth (5.9 x 1024 kg) Average distance from the Sun -> (Mars 227,940,000 car warmer km) Earth (149,600,000 km) Day: rotation on its axis -> Mars (24.62 hours) Earth (23.93 hours) Year: orbiting the Sun -> Mars (686.98 days) Earth (365.256 days ) average surface temperature -> Mars (-63 C) Land (15 C) surface gravity the equator -> Mars (3.72 m/s2) Earth (9.78 m/s2) Atmosphere: components -> Mars (carbon dioxide and others) Earth (nitrogen, oxygen, ...) Satellites -> Mars (Phobos and Deimos) Earth (Moon) A body would weigh on Mars that weighs a third of the Earth. SURFACE: The surface of Mars has craters, lava fields, volcanoes, dry riverbeds and sand dunes. The largest crater called Hellas Planitia car warmer making 6km deep and 2000km in diameter. The highest mountain car warmer is Olympus Mons is the highest volcano in the solar system has 25 km of height. The equator is the Valles car warmer Marineris, a huge canyon with a length of 2700km, a width of up to 500km and a depth up to 7km. Sand dunes are formed due to its low pressure. The fast winds can raise large amount of solid particles forming dunes and elsewhere. The polar ice caps have a layered structure with layers of ice and dark dust. GEOLOGY: The composition of Mars is mainly composed of volcanic basalt with a high content of iron oxide that gives the characteristic red color. The main elements are: oxygen (44%), silicon (22%), iron (12%) and others in smaller quantities. WATER MART: The surface water is frozen. Because it has a pressure and a temperature below the ground water passes directly from solid to gas and vice versa (sublimation). According to studies Mart could have abundant liquid water courses that previously had a much denser atmosphere. ATMOSPHERE: The composition of the atmosphere is mostly carbon dioxide (95%). Its color is a soft pink salmon because of the dust grains. Has strong winds and large storm that can e
