Jiri Brezina Field Trips

The following FIELD TRIPS are available for my science classes:

Development of Planet Earth

Surroundings of Pirmasens (near Kaiserslautern - Ramstein), Pfalz Mountains (Palatinate Forest), Rabenfels near Lemberg. The features of the geologic formations, illustrating the development of planet Earth about 230 million years ago (Early Triassic age, beginning of Mesozoic):

  • The red color of the sandstone is caused by finely dispersed hematite, Fe2O3, a highly oxidized (3-electron) iron. This oxidation could be caused by free (elementary) oxygen only. Therefore, occurrence of the red sandstones is evidence of the free oxygen available in the time of the sandstone formation. On Mars, similar red sands are common. The red color was responsible for the planet's name Mars, god of war, bloody god. By the way, hema in Greek means bloody red; blood is red due to hemoglobin, being red by the 3-electron iron too. This is why the free oxygen had to be available in the Mars' atmosphere sometimes in the past (currently, there is no oxygen in the Mars' atmosphere). Because we know that the free (elemental) oxygen can form in the given Mars' environment by photosynthesis only - we must assume that this process had to operate also on Mars in the past - an indirect evidence of photosynthetic life on Mars in that time.

  • Hardness of the sandstone layers increasing toward the younger layers is caused by increasing content of opal. This mineral is hard, formed from silica ooze in the waters. The silica ooze was released by tropical weathering of silicate rocks. This is why the increasing hardness of the sandstones, due to increasing opal cementation, indicates warming climatic trends during the sandstone formation.

Ries Crater around Nördlingen Saturday, APR-MAY-08 (the date has not yet been determined). This field trip includes both geologic and astronomic aspects: uniquely preserved meteor crater since its origin 14.7 million years ago, 24 km diameter, formed by the energy equal to 250,000 Hiroshima bombs. In comparison, the famous Arizona meteor crater (owned by Barringer family) has been formed relatively recently (5,000 to 50,000 years ago), its diameter is 1.2 km (= 0.75 mile) only. We will visit the famous Museum in Nördlingen, providing multimedial simulation of the impact etc...

(the street name above bears the name of the American planetologist who disclosed the currently accepted explanation of the Ries crater by meteor/asteroid impact).

Heidelberg, two Astronomical institutions

Meeting: McDonald's, Heidelberg (see above), Saturday, 3-MAY-08, 10:00h. We will go to
Heidelberg, onto the hill Königstuhl:
MPI of Plasmaphysics, Institute of Planetology, the Gate, Phone: 06221-516-0
LSW Königstuhl (Astronomical Observatory) - Mrs. Stefanie Schwemmer, Phone: 06221-54-1727.

1 Gentner Laboratory (Institute of Planetology), Max-Planck-Institute of Plasmaphysics:

a 9-foot model of the Moon; extraterrestrial materials: differentiated (metallic & stony), non-differentiated and carbonaceous meteorites. The latter ones contain both the chondrules and volatiles - therefore they represent the least altered remains of the solar nebula; they seem to be a few million years older than the solar system (Scientific American, October 1990, p. 14-15). Some of them contain all three crystal forms of carbon (diamond, graphite and fullerenes - see below) and grains of silicon carbide.

In addition to the two known crystal forms of carbon (diamond and graphite), a third one was discovered recently: fullerenes, buckey balls, or Buckminster fullerenes (named in honor of Richard Buckminster Fuller, American architect, who advocated using such geometric structures in architectural design) are spherical clusters of carbon atoms. The most stable is C60 (soccer ball structure); C70, C76, C84 are also relatively stable. Fullerenes are soluble in non-polar liquids, such as benzene and toluene. Their discovery, on which some scientists of the Department of Planetology participated, was honored by the Nobel Prize in Chemistry 1996.

Moldavites, the Bohemian tektites (glassy meteorites), are considered they formed by an impact of a meteor which caused the 24km diameter Ries Crater, about 14.7 million years ago.

2 Astronomical Observatory (LandesSternWarte Königstuhl)

presents a model of the solar system alley; walk through the Solar System and experience the relative distances of planets from the Sun, and the relative sizes of planets. We may also examine several types of telescopes, research instruments, and some results of graphically processed data on computer screen.

About Some Old Field Trips:

Report by the Research team ASTR-100 Ramstein, Saturday, 22 July 2000

We have seen an incredible number of Sun spots, and - two days later - I received a report from Space Weather, which confirmed our unusual observation: http://www.spaceweather.com:

SUNSPOTS GALORE. The Boulder sunspot number reached 401 on July 20th, the first time during the current solar cycle that the index broke the 400 mark. Such a large value is rare. During most 11-yr solar cycles, the Boulder sunspot number will exceed 400 on no more than a few days.

Another discovery - I talked about growing number of known satellites of the jovian planets (Saturn, Uranus, and recently Jupiter): http://spaceflightnow.com/news/n0007/21jovianmoon

Another exciting astronomical event some of my students have seen by a binocular, was the comet LINEAR - click on: http://www.spacescience.com/headlines/y2000/ast05jul_1m.htm. The comet Linear was visible below the rear part of the Big Dipper constellation (opposite to Polar star).
