Understanding the function of soil organisms is essential for the sustainable use of soil by the human society. Soil biology is almost no represented in the Czech school curricula.
We therefore proposed a practical inquiry based course focused on measuring soil respiration in different environmental conditions by acid-base titration methods. We evaluated our proposal in a university course and in secondary school (gymnasium) chemistry classes.
This course provides a good opportunity for application and further development of pupils' knowledge and practical skills in analytical chemistry in studying biological research questions.
