Principle
In this experiment, acid rain is to be artificially prepared by passing gases such as SO2, NO2 and Co2 through water.
Tasks:
The altitude profile of a hiking trail or route to school can be measured during a school trip or as an exercise for the students. The altitude profile can also be used to demonstrate that the atmospheric pressure decreases when the altitude increases ...
The weather sensor can be used to determine the height of a tower as a function of the change in air pressure with the aid of the barometric formula.
The compact Cobra4 Weather multisensor makes for fitting out your own weatherstation with little means. It allows the relations between air pressure, humidity and temperature, and also brightness, to be made understandable. Fluctuations over a period ...
The compact Cobra4 "Weather" multisensor can be employed as a simple means to setup a weather station, which can then be used to explain the relationship between the air pressure, humidity, temperature, and the light intensity. The measurement combina ...
Dew or frost can be formed on the inside of windows, although one has the feeling that the air in the room is quite dry. A cellar cannot be dehumidified on warm days in summer by simply opening the cellar window. This experiment shows why.
The drawing of maps is one of the favourite tasks of the students during geography lessons and of a high didactic value. The altitude measuring function of the Cobra4 Sensor-Unit "Weather" is a user-friendly tool which provides altitude values so that ...
How does the temperature of the air affect the temperature of the soil in the course of a day?
Demonstration experiment using wireless data communication to send readings to a large-size display. Knowledge of soil characteristics is highly important for agriculture. To familiarise students with this topic, two sub-experiments use pH readings t ...
Demonstration experiment using wireless data communication to send readings to a large-size display. How suitable are certain soils and plant substrates in terms of plant nutrition? This experiment is concerned with the measurement of conductivity, which gives an in ...
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, whi ...
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 t ...
Various types of woodland exhibit different sorts of climate data. Temperature, humidity and lighting conditions do not only depend on meteorological factors but also on the nature of the vegetation. The density of the tree canopy determines how much light can penet ...
