Scientific report-Water, land and air
analysis-
This activity is a final product of the Virtual Eden project. Students from the four countries collected water, land and air samples and then they analysed them. So, we can see
how clean our environment is.
Water
Methods and materials:
- water samples from various locations
- making a map of the locations
- macroscopic, microscopic and chemical analysis
- decantation and filtration for residues
- pH (pH-meter)
Kiskunhalas is situated in between two major rivers, the Danube and the Tisza. The town used to be surrounded by lakes, ponds,
swamps, all rich in fish.

Jastrzębie-Zdrój is situated at the watershed of two drainage areas in Poland: the Vistula river and the Oder river. Within the Jastrzębie-Zdrój city limits eight streams have their sources.

Kiskunhalas is situated in the great plain of Hungary, called Alföld. The air pollution is moderate here. The main source of pollution is a main road, which goes across this area. In addition, in the winters we have to heat up our homes and we also generate some carbon dioxide, nitric oxide and loose soot with it.
Air-Hungary-
Plants aren't affected by air pollution. The leaves are nice green, with no significant discolorations.
Lichens are good indicators: if you can see lichens somewhere, the air has got very small amount of SO2 there or it hasn’t got any at all. This means the air is not polluted.
Air-Hungary-
We have found a lot of lichens around our school.
Air pollution is one of the most dangerous environmental hazards. Air pollutants arise from a wide variety of sources, although they are mainly a result of the combustion process.
Air-Poland-
The map lichen can be seen in the survey area. It indicates low air pollution.

Dub nad Moravou is a village far away from industrial centers.
Bucharest is the largest city of Romania, so it is the most polluted. The centre of Bucharest, where our school is situated, is the most polluted zone of the city.

Soil
Methods and materials:
- soil samples from various locations
- making a map of the locations
- macroscopic, microscopic and chemical analysis of soil samples
- decantation and filtration
- pH (pH-meter)
Soil-Hungary-
In Kiskunhalas, students found mainly sandy soil with humus and lick soil.

Soil-Poland-
In the area of Jastrzębie-Zdrój two types of soil are predominant: Podzols and Cambisols.
In the surveyed area three illegal landfills were traced. Each of them extends on the area 3-4 m². They consist mainly of household waste and old tires.

The main agricultural crops grown in the zone of Dub nad Moravou area are potatoes, wheat, maize, sugar beet, oilseed rape and vegetables. The brown soil around the village is very fertile, with humus horizon about 30 cm high.

Bucharest is situated in the south eastern corner of the Romanian Plain, in an area once covered by the Vlăsiei forest, which, after it was cleared, gave way to a fertile flatland.
Three samples of soil were taken and analyzed.They contained roots, microorganisms, residues, particles of sand and broken pebbles. Illegal landfills were found near the school and in the center of Romana Square.

After analyzing the most important elements of our planet and, definitely, the indispensable things for our life, we found out that the Earth is in trouble. This trouble isn't big, provided that we care about it. We must think twice before doing something that might be harmful to the inhabitants of our planet.
But if we don't care, it's going to be a disaster!
