Manipulation:
The air becomes enriched in CO2 due to the respiration of organisms placed in the large chambers. The heavier CO2 descends through the pierced lid and clouds the limewater contained in the small chambers. The diameter of the chambers is adapted for small samples. Test the experiment on the BLOB with your students.
Format: 6 tests
Duration of the experiment: 50 min
Storage duration: No constraints
Storage conditions: Room temperature

- 6 large containers in PE (Ø x h): 3.5 x 7 cm and lids.
