Observations:
- Water Clarity – mostly clear, but with some microscopic material floating around
- Daphnia – increased in size
- Snails – increased in size, one abandoned its shell (Albert), showing active movement
- Evaporation and condensation in both levels
- Soil is dry
- Zero plant growth
- Cotton strings are moist in aquatic level, but appear dry in terrarium level
- Water level unchanged
- 9 cm
- Gravel appears the same
New Wondering:
- How is there enough water to create condensation in the top tier but leave the soil extremely dry?
 |
| We observed that the water clarity was relatively unchanged, as well as the water level. We inferred that a small amount of the water evaporated, causing the condensation shown above. |
 |
| Although there was a small amount of condensation present in the terrestrial tier, the soil appeared extremely dry. We did not observe any noticeable plant growth. |
