Principle

Knowledge of the soil is of great importance for agriculture. In order to familiarize the students with this topic, two sub-experiments are used to show, on the basis of pH determinations, how different soils are (sub-experiment "Characteristic pH values of soils") and how great the differences are even within a soil (sub-experiment "Soil profile").

Benefits

Experiment is part of a complete solution with numerous experiments in the field of ecology
Measurements possible indoors and outdoors, for mobile and desktop use
Especially understandable and didactically prepared description of the experiment (relevance to everyday life, etc.) including protocol questions
Future-oriented teaching: Integration into digital science lessons with tablets or smartphones
Increased motivation of students by using the intuitive measureAPP

Tasks
