Principle
The measurement of ammonium is a common method in analytical chemistry and is also used for the quality determination of water and soil.
Benefits
-
Particularly comprehensible and didactically prepared description of the experiment (relevance to everyday life etc.) incl. protocol questions.
-
Teach with an eye to the future: Integration into digital science lessons with tablets or smartphones.
-
Increased motivation among pupils through the use of the intuitive measureAPP.
-
Increased media competence.
Tasks
-
Measure the ammonium concentration of different samples (soil and water samples in biology lessons, ion measurement in chemistry lessons).
-
If a nitrate sensor is available, the nitrate and ammonium concentration of the samples can be compared.
Learning Objectives
-
Investigation of the ammonium content of various samples in biology and chemistry lessons
-
Comparison between ammonium and nitrate contents of samples using an additional nitrate sensor
