Bottle biome observation

The bottle has condensation along the sides inside the bottle. The water is the same as it was earlier somewhat clear but dirt is starting to cling onto the string in the water. The water is lower than before and the seeds have sprouted and the plants have grown well almost to the very top of the bottle. Water has debris in it and it’s a little bit murky. Didn’t have a ruler but I think the waters only at 3 cm.

Bottle biome observation – Iyanae D and Makayla

We received two 2 liter bottles that have been cut in half. Then we put gravel in the bottom half put half a string through the hole on the bottle top. We put dirt water and seeds in the top half and sealed the bottles together with tape. I’m hoping the plants will grow well and something unexpected occurs. We have reused bottles one half had a lot of dirt on it and I think it may grow mold.
