Unknown Principle Representation of the photosynthesis performance of a plant by measuring the increase in oxygen pressure in white and green light or in the dark. 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
Compact, easily transportable experimental set-up Suitable for demo experiments and practical training Flexible test execution thanks to wireless data transmission
Tasks - Comparison of oxygen pressure increase during photosynthesis under white light, green light and without light
- Discussion of the reasons for the differences in the rise of the printing curve
Learning objectives - Photosynthesis
- Intensity and color of light
- Pressure measurement
