Ali Velshi First Marriage

Karst - How a Slovenia / Croatia trip a lesson was

fall break 2005-40 counterparts in Rostock and the surrounding area make up, to explore a part of the Balkans. The impressions are varied - from the Alpine region Kranska Gora, on the Venetian city of Piran on the Adriatic as far as the barren landscapes of Istria and the island of Cres. But everywhere we followed the forms of karst. How can you convey this impressive impressions on the students? In class 6 can be defined us as a teaching Southeast Europe-including specific landscape in the karst area "as the contents, and geological factors on the relationship of water and geological structure is to be received in the form of an experiment on the solubility of limestone open teaching methods used. The objective of the Framework is: "In the treatment of selected areas, students learn about typical geographic phenomena in the regions. They capture that form the basis of the natural conditions for human existence and human understanding to use them in space. The knowledge about the interactions of the geological factors in concrete is Subjects at depth example. " had then I am alarmed to find that is questioned in any other place in the framework plans karstification, not in class 9 (water) and not in Class 12 (soil formation). There is therefore up to the full extent of the teacher, as he approached with this issue on to the students. In the 6th I would class schedule for this subject at least four hours. This time is needed if one uses the forms of open. It is also possible, using only textbook, atlas, manual and the images of this topic in an hour "work off" - that would be a pity. 1. Hour: Introduction and limestone as the starting material 2 Hour: "Stony ground" is karst - a mountain gives its name (group work) 3 Hour: presentation of group results 4 Hour: summary and consolidation and control at the end of the 4th Lesson could then be a written knowledge test on Southeastern Europe. first Three hours images could serve as a preparation for the lesson. "It begins" shows an approximately 50 cm x 80 cm 10 cm lowered piece of turf in the area of Velka Planina just north of Ljubljana (Slovenia). The Okroglica is a 90 m deep shaft, whose floor opens into a cave. The shaft was created by resolution of the rock, crumbling and collapsing. Here the Reka disappears for the first time (see figure below). The "Festive cave is part of the underground flow of this river.

1) "begins" 50 cmx80 cm (Velka Planina - Slovenia) 2) "Okroglica" - 90 m deep (Škocjan - Slovenia) 3) "Noisy Cave Škocjan" Slovenia students are asked to describe the pictures and speculations say what is presented here Þ Þ Þ cave collapse shapes as the cause of the collapses running water as the cause of the cavities with what force the water can create such a huge cavities? Q: Constant dripping wears away the stone "? Answer: that alone is enough here - help from chemistry limestone - a special material handpieces hand out to describe to the students and leave with 10% hydrochloric acid can be carried out to demonstrate and show how the process (but much slower) with carbon dioxide takes place (must be crushed by the rock dolomite) - color (white to gray-brown, some with fossils score - in the sea or fresh water formed by organisms (shells and skeletons of worm , shells, coral) - (make a scratch test), Hardness 5 - numerous cracks and crevices water can seep easily and dissolve in the deeper layers of the lime Þ creating different landscapes (more pictures)

7) karst landscape on the Croatian island of Cres 8) of the Reka River in Slovenia, a deep valley has created - then it disappears and Caves can be formed

9 to 11) caves in the area Škocjan (Slovenia) second Hour group work for Karst - "students explore the phenomenon of" as a repeat will be shown the pictures again second "Stony ground" is karst - a mountain gives its name Group 1: card working (Atlas, copy Karst in Germany, the world map) a) Where is the mountain karst with the name? b) Where there are karst landscapes in Germany? c) Where there are karst world? Group 2: Venice and the Karst (LB Westermann terminal 6 1999) a) Why is the karst landscape waldarm, or even waldlos? b) What were the consequences of human activity on the landscape? Group 3: sinkholes, and caves Polje (LB Westermann terminal 6 1999) a) Describe the block diagram of the karst landscape in the LB. b) Explain the formation of karst forms. Group 4: stalactites and stalagmites (LB and additional material) a) inform you about the growth of these structures. b) cavers - adventurers or scientists? Group 5: The life of the people in the Karst region a) Agriculture in Slovenia and Croatia b) The caves and tourist Similar to group work You can, of course, the 5 topics and some exercises to topography as stations embellish. Gathering of information through short student presentations and completing the worksheet in the workbook Possibly. as setting: use of school video "karst" Note: If you want to edit this issue with older pupils should look at http://www.webgeo.de/ under topics "Karst" offered the learning modules.
