The pH value of various soils

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 ...

Salinity of soils and plant substrates

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 ...

Raised bog and fen

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 ...

Salinity changes of a watercourse

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 ...

We visit a wastewater treatment plant

Principle

A visit to a water treatment plant reveals some fascinating procedures and purification methods. We will not merely be concerned with interesting impressions, but instead we will increase our understanding for microbiological processes by measuring the key parameters: ...

We determine our heart frequency

Principle

An electrocardiogram (ECG) enables you to observe the regular sequence of heart contractions as well as to determine your heart frequency by determining the interval between two heart contractions. In a second experiment, you will measure the heart frequencies of test persons of ...

We investigate our physical fitness - the heart under stress with Cobra4

Principle

An electrocardiogram (ECG) can record the sum of the electrical activities of all of the heart muscle fibres. Under stress, cardiac activity increases in order to maintain the stability of the cardiovascular system. The heart contraction cannot be controlled at will. This ...
