Calculating the CO2 exchange rate in room air

Principle
Different environmental environments are created in the three chambers, which are interconnected. This is a long-term experiment that can be continuously monitored and measurements can be taken.

Benefits

• Development of an independent ecosystem in the classroom
• Evolution can be observed through the transparent chambers
• Changes in measurement parameters can be recorded and documented through the Cobra SMARTsense sensors

Tasks

1. The students create different environments in the three chambers.
2. In a second work step, the students observe the ecosystem they have created and measure various, relevant environmental factors.
3. In a third work step, the students change some factors in their ecosystem (light, temperature, ...) and observe the changes that occur as a result.

Learning objectives

• Interaction of ecosystems
• Influence of the changes in one ecosystem on others
