Benefits
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. As a result, the experiment is ...
The compact Cobra4 "Weather" multisensor can be employed as a simple means to set up a weather station, which can then be used to explain the relationship between air pressure, humidity, temperature, and light intensity. The measurement combination of a Cobra4 Mobile-Link and a ...
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 contour lines can be added ...
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 ...
