ASK THE SCIENTIST!

Getting into conversation with a real scientist? No problem! The traveling exhibition "Diversity counts!" makes it possible. A topic of the exhibition is explained in detail and related to recent research in the field of geosciences or mining. The offer is designed dialogically: It should encourage questions and lead to exciting discussions in the group. The exhibition will start with a short keynote speech. Depending on the topic, the scientist shows in the hands-on lab "Forschungsreise" suitable handpieces and rehearsals or short film contributions and photos. Participants are invited to actively participate, to study, discuss and ask questions.

Topics:

23. and 27.10 .:
"Biodiversity in an acid ocean"
(Prof. Broder Merkel/Dr. Thomas Grab)

On October 23th and 27th, scientists from the TU Bergakademie Freiberg´s "Scientific Diving Center" will accompany you on an expedition to the submarine volcano Panarea (Italy), where scientists will study a four-square-kilometer area that is massive due to submarine vulcanic carbon dioxide gas leaks. This area gives the opportunity to explore the impact of carbon dioxide on seawater and marine biodiversity on a natural laboratory, including not only normal marine species, but also autotrophic bacteria on the up to 130°C sulphurous fluid spills. But the submarine Volcano Panarea between Stromboli and Vulcano offers many other exciting scientific aspects...

30.10. and 3.11 .:
"I love you, I do not love you, I ... relationship models between plants and insects"
(Dr. Elke Richter/Dr. Roland Achtziger)

6. and 10.11.:
"Plants as miners - diversity creates profit"
(Prof. Hermann Heilmeier)

Value elements such as germanium and rare earths, which are in high demand in high technology, can hardly be mined due to the extremely rare deposit deposits. However, since they are present in soils everywhere, one can use the property of (energy) plants to pick up these elements from the soil and concentrate them in their biomass. Because of the usually low concentrations of these elements in soils, a scientific challenge is to increase the availability of elements for the plants. This can be achieved by mixed cultures of several species and above all a high diversity of root-type bacteria, whose diverse chemical and physiological mechanisms positively affect the soil enviroment and bring the value elements into solution, as shown in the event.

13 and 17.11 .:
"Discover the unknown or how species get their names"
(Dr. André Günther)

To protect biodiversity, it must be known. For many years Dr. Andre Günther is researching the tropical jewel dragonflies and still exposes new things. These colorful insects are characterized by spectacular threatening and advertising flights. The analysis of high-speed records of these flight styles is a tool for discovering and scientifically describing previously unknown species. Only when a species is described, its potential threat can be assessed in red lists. Red Lists are a scientific tool to identify priorites in biodiversity conservation and to plan conservation measures.

27.11. and 1.12 .:
"Raw materials in the deep sea - An option for the future?"
(Prof. Thomas Seifert/Tom Járóka)

4. and 8.12.:
"Fossils - evidence of biodiversity in the history of the earth"
(Prof. Thomas Wotte und Prof. Jörg Schneider)

Collecting fossils in not only an exciting hobby, fossils are also of scientific interest. The Freiberger paleontologists investigate fossils from marine and continental rock strata to draw conclusions about the evolution of organisms, to reconstruct past habitats and to make age dating. Exciting questions that scientists are dealing with include for example. the emergence of higher life, the reconstruction of seawater temperatures or the conquest of the mainland and the associated specializations of the organisms.

8. and 12.01.:
"Water, forest and meadow: historical perception of nature in the documents of the Bergarchiv Freiberg"
(Dr. Peter Hoheisel)

The Bergarchiv Freiberg is a special archive for the historical documents of the Saxon mountain administration and the mining industry. Water, forest and meadow appear primarily in the archives as resources. However, issues of resource scarcity, resource destruction and conservation also play an important role. And what we now refer to as enviromental protection can also be found (under other terms) for centuries in the historical mining documents. Selected examples illustrate the tension between the use and destruction of water, forest and meadow in the past.

15. and 19.01.:
"When is a forest a forest?"
(Prof. Jörg Matschullat)

Using the example of the Amazonas rainforest, we go into the (ecosystem) functions of forests. What happens in deforestation, what happens in case of natural disturbances? How do soil, atmosphere and biology react to such changes? How does nature achieve high biodiversity and why is that important? And does a forest look far beyond its surface? These are our topics.

Date: Always on Tuesdays at 5 pm and Saturdays at 4 pm, additional dates for school classes can be booked individually

Costs: Adults 3 Euro, children 2 Euro.
