Topics

  • No.: TG01 – Solar system
    Planets and Stars reflective or luminous moving or being moved an overview on planets of our solar system and planetary science from earth and out of universe.
  • No.: TG02 – History of the earth
    4.5 billion years of development on planet earth. How can we know this? Searching for witnesses for the fact, that the town of Kassel e.g. had already been lying in a desert in the past and that a few million years later a visit to Kassel would have been only possible by wearing a compressed air cylinder and a diving mask.
  • No.: TG03 – Volcanism
    Volcanic roots and why magma moves upwards against gravity. Let’s discover old volcanoes in the region and giant volcanoes on Mars. What are the consequences of Volcanism?
  • No.: TG04 – Earth dynamics
    Inside the earth heat generates giant amounts of power, which cannot be controlled. Earthquakes, volcanism, but above all movement, movement, movement ... It is worth to take a closer look into the blast furnace of earth.
  • No.: TG05 – Plate tectonics
    The surface of earth is everything else than just solid. Alfred Wegener observed interesting things, which conclude in an exciting “earth puzzle”. What is the speed of the continental rafts „Europe“and "America“?
  • No.: TG06 – The Earth’s magnetic field
    What links magnetic fields to electricity and why and how shows an iron needle our way back home when we are lost in the field? Earth magnetic field as a turncoat and magnetic fields in space.
  • No.: TG07 – Planetary science
    Landscapes on earth and in space. Compare the landscapes of Mercury, Venus, Earth and Mars. Find differences and analogies amongst others by using 3D- pictures of Mars from the DLR (Deutsches Luft- und Raumfahrtzentrum). An introduction to „Valles Marineris“.
  • No.: TG08 – Our Moon
    More than 80 % of the surface of the moon is highland with a lot of craters spread around. Beside this the highlands reflect high amounts of sunlight. What other kinds of characteristics shows our companion and how are we influenced by them? Why it is important to go for another walk on the moon.
  • No.: TG09 – Mars
    Season changes causing enormous dust storms; a thin atmosphere with 95% CO2, beside this mars is the host of the greatest volcano of the solar system. This makes Mars a special planet which still gives scientists a lot of riddles.
  • No.: TG10 – Galileo Galilee and Jupiter’s moons
    In 1610, Galileo discovered four moons of Jupiter. One hot and active, one ice cold, one as the greatest moon of the solar system and one with nine Palimpsests… A closer observation is worth the trouble. Until today there are 63 moons of Jupiter known.
  • No.: TG11 – Satellite and Asteroid
    How did they develop, where do they come from and where can they be found? Are asteroids dangerous? Travelling through space tracing our satellite and the ’Kuipergürtel’
  • No.: TG12 – Giant gas ball Saturn
    A gravity 95 times the mass of the earth, therefore able to catch comets. Emitting more heat than receiving. With seven groups of rings Saturn is not only a beauty but with its moon Titan an exciting goal of current science.
  • No.: TG13 – Venus, our sister planet
    It is covered by a gigantic Greenhouse; almost impossible to imagine on earth. Always hidden under clouds, which is the reason that - after sun and moon Venus is the lightest body in the sky. A journey to an inhospitable planet which wouldn’t be possible in reality…
  • No.: TG14 – Alternative energies
    The power of the sun, wind and water fires the imagination of scientists to new and more exciting ideas how to gain energy. It is interesting to build and observe our own power station.
  • No.: TG15 – Climate
    Everybody is talking about climate. What is „climate“, where does it originate and why is “climate catastrophe” rather a “climate change”. Learn about scientific findings on the climate of Mars.
  • No.: TG16 – Sun, light and colours
    A giant gas ball, a source of heat, a donator of light the sun; offering livelihood for all life on earth and being in central position for all planets of the solar system.
  • No.: TG17 – Atmosphere
    A thin layer of gas is enclosing our planet earth, saving our existence. A complex system in need of protection will be explained and experienced under this topic. Why can’t Venus give livelihood to human beings?
  • No.: TG18 – Weather
    From clanking, cold, star clear winter nights up to pressures, humid thunder like summer afternoons. Is there weather on Venus? Physical and chemical procedures in the atmosphere are the steersmen of weather on earth.
  • No.: TG19 – Deep-sea research
    The deep blue is dark, cold and mysterious. Gain knowledge about the unknown deep of the oceans. Technology makes possible what was unreachable for human beings. A physical challenge...
  • No.: TG20 – Ocean research
    There are currents, reefs and lagoons under the surface of the sea. Oceans are giant chemical pools collecting minerals, water and detritus. What Humboldt was fascinated of and old salts have already used for many years.
  • No.: TG21 – Rocks
    Rock is the substance various planets crusts are made of and which can tell exciting stories. Minerals are not just jewels and rocks are not just grey. Let’s go on a treasure-hunt in Germany and on the planets.
  • No.: TG22 – Soil science
    Life, air and minerals – that’s what soil exists of. Sun, wind, rain and ice are the reasons for the weathering of the surface of our earth, so that there sometimes develops a thin, colorful skin in which a lot things are going on.
