| July 6 |  |
We bought a water tank in a home center nearby. |
 |
We took out the contents of the box. Because the filter was contained, we use it. There were the bag that contained the bacteria. | |
 |
We washed stones to use for the water tank biotope. We fetched these stones from school biotope. These stones were heavy, and it was hard to carry them. | |
| July 7 |  |
We spread gravel all over the water tank today. Therefore at first we put gravel in a bucket. |
 |
We wash gravel with tap water. The image was a feeling washing rice. We should wash three times of gravel. | |
 |
We put gravel in a water tank. We had a hard time to take all out of the bucket. | |
 |
After having spread gravel, we set the stones which we washed yesterday. We spent time to think about a combination. | |
| July 11 |  |
We bought soil to use for a part of the land. We bought this as well as a water tank in a home center. Was a soil usable for plant upbringing? |
 |
We made a land part. We had a hard time to use up a soil. | |
| July 13 |  |
We gathered the plants such as the fern from the school biotope. |
 |
A mushroom grew in the school biotope because of rain. It may be a kind with the poison. | |
 |
We collected plants of the bank of the pond. | |
 |
Similarly we gathered the moss in the bank of the pond. | |
 |
We inoculated a land part of the water tank with them. The moss increased from here. | |
