We live in a universe of colours. Artists create colours. Colours mobilize emotions. Knowledge create products change colour with temperature, inform us of meteorology and of conservation related to humidity. Colour underlies language learning. The colours of the flowers facilitate the reproduction of plants, colours attract insects . Universe is present with different colours through telescope; each stellar object tells us a story. To the eye, the objects have different colours.
Students ask events of language of colors

  6. 6. ü I wonder why the sun is hot? ü The center of the sun (core) is formed by a kind of gas cloud (plasma) with hydrogen and helium. There is a force that unites everything inside (gravitation pressure) and there is a war into (hydrogen fusion), consuming hydrogen and helium increase. This war (fusion) releases energy and increases a lot the core temperature to 15 million degrees Celsius. The surface temperature of the sun is about 5600 degrees Celsius. Our body temperature is 37 degrees Celsius. MCarmenDiezCalzada.mdiez125@gmail.com..2015_16Thecolourlanguageatuniverse.ErnestLluchL.VilassarMar_BCN_Spain The colour language at Universe
  7. 7. ü I wonder why people's eyes are a different color ü Our skin, hair and eyes are very different colors. These colors are due to the same material (pigment) called melanin. Melanin gives brown or colornegre. The amount of melanin present in our eyes iris (the colored part of our eye) determines the color. When there is a lot of melanin are brown or black. If there is a small amount of melanin, melanin particles diffuse the light and make it appear blue. Something similar happens with particles that diffuse light in the sky and make it see blue. ü MCarmenDiezCalzada.mdiez125@gmail.com..2015_16Thecolourlanguageatuniverse.ErnestLluchL.VilassarMar_BCN_Spain The colour language at Universe
  8. 8. ü I wonder why water falls are round and are not triangles,and blue colour. Nature shows that everything is organized to have a minimum of energy. The drops are formed by units (water molecules) which together with the way they have less energy. The best way is the raindrop round. Sea colour depends on existing substances at sea Rayleigh explained that electromagnetic waves of visible light collide with small particles or substances (algae, salts) and are separated. Some waves are absorbed and others are reflected. We see the colors of the reflected waves.

  9. 9. I wonder why Sun is red ? ü • Sun is a star because it emits white light (energy). Sun light brings with it all the colors of the rainbow: travel as waves and particles (photons). • When the green sun combining with the blue sky, our eyes see yellow colour. Photons travelling are scattered far from our vision by particles in the atmosphere. Photons with wavelengths longer (orange and red) avoid dispersion entering into atmosphere easily. This is the reason we see these colors without changing and we associate to Sol. ü MCarmenDiezCalzada.mdiez125@gmail.com..2015_16Thecolourlanguageatuniverse.ErnestLluchL.VilassarMar_BCN_Spain The colour language at Universe
  10. 10. ü Why does chicken tail is blue when sun shine? Some substances change color with humidity. An example is the cobalt chloride: when there is humidity that material captures water from the air and takes red colour. We can use this to build a warning of rain. The air has high humidity when it will rain. MCarmenDiezCalzada.mdiez125@gmail.com..2015_16Thecolourlanguageatuniverse.ErnestLluchL.VilassarMar_BCN_Spain The colour language at Universe
  11. 11. ü I wonder how they prepare an egg of blue-green color Juice prepared with cabbage contains substances (anthocyanin molecules) that change colour from acidic substances. We add a few drops of cabbage extract (lilac) to an acid: it shows red. These drops in a basic medium (bicarbonate, yeast cakes, egg) shows a green or blue colour. ü MCarmenDiezCalzada.mdiez125@gmail.com..2015_16Thecolourlanguageatuniverse.ErnestLluchL.VilassarMar_BCN_Spain The colour language at Universe
  12. 12. ü Why does Aurora Borealis appear? Clouds of stellar particles travel in space at speeds very large (300 to 1,000 kilometers per second). When they approach Earth, forms a kind of elastic rubber and are attracted to a circle the North Pole; Earth's magnetic shield is the cause. Then energy is released, and we know that the energy released offers many radiation. We see radiation as colors. ü MCarmenDiezCalzada.mdiez125@gmail.com..2015_16Thecolourlanguageatuniverse.ErnestLluchL.VilassarMar_BCN_Spain The colour language at Universe
  13. 13. ü I wonder why white is divided in other colours through a triangle of glass. The triangle is called optical prism. It is an object that makes travel light with different speed and angle when crossing the triangle (reflection and refraction of light). It breaks the light in different waves of energy that are separate and we can see the colours of the rainbow. ü MCarmenDiezCalzada.mdiez125@gmail.com..2015_16Thecolourlanguageatuniverse.ErnestLluchL.VilassarMar_BCN_Spain The colour language at Universe
  14. 14. ü I wonder why storms exist in the sun ü Wars that occur inside the sun produce magnetic fields around the sun (plasma loops). Every 11 years solar activity reaches a maximum value with large explosions plasma: these are solar storms, reaching high temperatures near 20 million degrees. During a solar storm, radiation and particles expelled a lot of energy. Reaches Earth in 8 minutes. Our atmosphere protects us. The last was in 2012.

  15. 15. ü I wonder why colours are cold and hot Warm colors are those that go from red to yellow. Cool colors are ranging from blue to green. This division is simply human feeling and experience is completely subjective. A cool color and a warm complement each one. However the energy associated with colors is reverse. The red colour has an associated electromagnetic radiation with less energy . The blue and violet colors has an associated electromagnetic radiation with high energy. ü ü MCarmenDiezCalzada.mdiez125@gmail.com..2015_16Thecolourlanguageatuniverse.ErnestLluchL.VilassarMar_BCN_Spain The colour language at Universe
  16. 16. ü I wonder what nebula is. It is the interstellar matter. It’s formed by gases and particles. Nebula emitting colour light related to elements forming it. Swan Nebula contains hydrogen in green colour, red colour of sulphur, and oxygen in blue colour. ü MCarmenDiezCalzada.mdiez125@gmail.com..2015_16Thecolourlanguageatuniverse.ErnestLluchL.VilassarMar_BCN_Spain The colour language at Universe
  17. 17. ü Why does conos have colour? Retina is at the back of your eye and it has light-sensitive cells called rods and cones. The cone cells are sensitive to different wavelengths. Cones interpret the primary colors. The cone cells are different in each animal species.
