Calidad del auga - contaminación con metales pesados

Principle

Heavy-metal ions may be carried into surface or ground water from mining fields or via the waste water of galvanic or similar production sites. They block the effect of enzymes so that the processes in the metabolism of the organisms that are controlled by these enzymes may ...

Cambios en la condición lumínica en bosques caducifolios

Principle

Why are there only a few different kinds of plants in a deciduous forest? Except for having trees that are all approximately of the same height, hardly any other plants grow in a deciduous forest, except for young plants of the same type of trees. This experiment shows how the ...

Cambios de pH en el curso del agua

Principle

The pH value (a measure of the concentration of hydrogen ions) in running waters depends on the geological conditions, the pollution load that is caused by agricultural production, and on plant activities. This experiment shows how the pH value of a stream changes even at a short ...

Estudio del pH de diferentes suelos

Principle

Information concerning the quality of soils is of great importance for agricultural production. The students are familiarised with this subject via two experiments with pH measurements that show how much soils may differ from each other (experiment  "Characteristic pH values ...

Salinidad de suelos y sustratos de plantas

Principle

How suitable are certain soils and plant substrates for the nutrition of plants? This experiment is about measuring the conductivity, which in turn provides information as to which of the examined soils and plant substrates already contain nutrient salts for plant growth and to ...

Turberas y humedales

Principle

Bogs and fens are habitats of plants that are specialised in soils with constant excess water. Apart from this specialisation, bogs and fens differ significantly from each other. Raised bogs and fens, for example, have different plant communities, which is due to their varied ...

Cambios de salinidad en el curso del agua

Principle

This experiment shows how the salt that is washed out of an abandoned potassium rock pile drastically increases the salinity of a watercourse, as well as how the salinity decreases only slightly further downstream, and how the salinity can still be measured after the stream has ...
