Principle

When visiting the sewage treatment plant with its fascinating processes and cleaning methods, we are not content with sensual impressions alone, but deepen our understanding of the microbiological processes by measuring the most important parameters: temperature, pH and salt content.

Benefits

• experiment is part of a complete solution with numerous experiments in the field of ecology
• Measurements possible indoors and outdoors, for mobile 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.
• Increased media competence.

Tasks

1. visit of a sewage treatment plant and sampling
