1-Water, land and air analysis- 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.

3WATER -Hungary-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.Sample 1Sample 3Sample 2SóstóDongéri canal, where thermal water is let into the canalDongéri canal, near the school8 pH8,5 pHMinerals, plants and algae; water is kind of green
4WATER -Poland-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.

11Air -Hungary-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.Plants aren't affected by air pollution. The leaves are nice green, with no significant discolorations.
12We have found a lot of lichens around our school. Air -Hungary-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.We have found a lot of lichens around our school.
13Air -Poland-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.The map lichen can be seen in the survey area. It indicates low air pollution.
14The outskirt of the surveyed area Air -Poland-The outskirt of the surveyed areaSample 1A large dust contentSample 2A small dust contentIn the woodsSample 3
15Air -Czech Republic-Dub nad Moravou is a village far away from industrial centers.The corner of a school buildingSample 1Large pollution – dust and dirtNo dust or dirtAt the church, near the village parkSample 2
16Air -Romania-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.

18Soil Methods and materials: soil samples from various locations making a map of the locationsmacroscopic, microscopic and chemical analysis of soil samplesdecantation and filtrationpH (pH-meter)
19Roots, leaves, microorganisms, residues, twigs. Soil -Hungary-In Kiskunhalas, students found mainly sandy soil with humus and lick soil.Roots, leaves, microorganisms, residues, twigs.A soil sampleNearby fields8,8 pH
20Soil -Poland-In the area of Jastrzębie-Zdrój two types of soil are predominant: Podzols and Cambisols.
21Soil -Poland-A soil sampleIn the forest5,5 pHIn 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.
22Soil -Czech Republic- A nearby field A soil sample 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.A nearby fieldA soil sampleSmall plant roots, remains of soil microorganisms, residues, leaves and twigs5,7 pH
23Soil RomaniaBucharest 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.
24Soil Romania 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.

26We don't want the future to be a disaster, do we?! 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!We don't want the future to be a disaster, do we?!Good luck for saving our planet!
27One of the most important activities of the Virtual Eden project is the analysis of water, air and soil, because we must know which are the problems of our environment to be able to fix them.Children in Kiskunhalas collected three samples of water: one from Sosto, and two from the Dongeri canal. In both cases, the water was a little basic.Jastrzębie-Zdrój is situated between the Oder and the Vistula and eight streams have their sources in the city.The two samples were collected from a pond and a spring. In both cases, the water was almost neutral.Students in the Czech Republic analysed two water samples from the Morava river and a garden lake. The water was almost neutral, which means very low pollution.These are microscopic findings in the analyzed water.In Romania, three water samples were collected. Two of them were taken from rivers in large towns and the third from a natural lake in the mountains.We found that the water from the rivers was largely polluted, but the one from the lake was clear.Hungarian students didn’t see high pollution in the air, as the plants weren't affected.There were also lots of lichens on the trees, which show the purity of the air. Lichens are very sensitive to toxic gas, like carbon dioxide, and when the air is polluted, they can't survive.Polish students also saw lichens on trees, so the air was not full of toxic gas.There were lots of dirt and dust on the samples from the outskirt of the surveyed area, but none on the ones from the forest.Lichens were also found in the Czech Republic, especially in the park, where the air is clean. But on the roads, there were lots of dirt and dust, made by the cars.Especially in the center of Bucharest, there’s always a heavy traffic, so the air is largely polluted.In the schoolyard, there was dust in the air. But in the outskirts of Bucharest, air was not polluted and plants were healthy.Children in Kiskunhalas found basic soil on the nearby fields.In Poland, the most common types of soil are Podzols and CambisolsSoil in the forest is not polluted, but we must avoid creating illegal landfills.In the Czech Republic, soil analyzed by the students wasn’t polluted, only containing ordinary natural remains.Students in Romania collected three soil samples, two from the area of the city, one from Moieciu town.They largely contained natural remains, not being very polluted.The most polluted sample was from the center of Bucharest and the less polluted – from Moieciu, a small town in the mountains.After analyzing water, air and soil we found out that we need to protect our planet in order to be able to live on it. If we don’t care the future will surely be a disaster.
