Carbon cycle enclosure

Full description

Simple and clever enclosure for the experimental study of carbon cycle-based exchanges:

- Atmosphere - hydrosphere relations (Dissolution / Venting)

- Atmosphere - biosphere relations (Respiration / photosynthesis)

- Atmosphere - human activities relations (pollution, CO discharge₂ by combustion, etc.)

The carbon cycle enclosure provides you with a full, encouraging and easy to use investigation tool.

The different CO₂ exchange issues may be dealt with by different pairs to ultimately build the carbon cycle using a collaborative method:

- Thanks to the CO₂ probe, by introducing CO₂ rich air (exhaled air) via the syringe into the enclosure full of water, it is easy to highlight the CO₂ dissolution in the water by monitoring its reduction in the airborne part.

- Conversely, using CO₂ rich water will highlight the CO₂ venting into the atmosphere.

- If there are leaves or flowers present, the respiratory and photosynthetic exchange measurement enables the relationship between atmosphere and biosphere to be discussed.

- The influence of human activities in enhancing the atmosphere with CO₂ is also simple and quick to illustrate by introducing into the enclosure air sampled near an exhause pipe or the flame of a candle.
