Principle
Water can have different oxygen concentrations in different states. This will be demonstrated in this experiment.
Benefits
- Especially understandable and didactically prepared description of the experiment (reference 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
Students will use the Cobra SMARTsense Oxygen Sensor to measure the oxygen content of tap water, stale water, refrigerator cold water, hot water and water with a stem of water plague (Elodea canadensis).
Learning Objectives
The students should recognize that the oxygen content is influenced by the temperature, but also by the plants present in the water.
