Principle

We are dealing here with circuit learning for four work groups. Use is made of the Cobra4 Sensor-Units and Mobile-Link handheld measuring instruments that are provided in the environment and outdoors experimentation case. One of each of the instruments is required at each of the four stations.

The learning stations encompass measurements of conductivity, pH, temperature and weather with the Sensor-Units. The students can so familiarize themselves with sensing technology and measured variables. This learning circuit is in general suitable for first scientific experiments and, in particular, as entry to the Ecology/Environment theme.

Benefits
