Week 6: Observations

11/5/2015

 
My, how those plants have grown! We still have plenty of condensation on our bottles. Our soil levels seem to be slightly lower than they were last week,

The height of our tallest plant is up to almost 6 cm. Wow! Our other plants are 2 cm, 3 cm, and 3.5 cm. Our smallest plant doesn't seem to have grown. But wait! A little tiny plant is starting to emerge along one of the edges of the bottle. So now we have 5 sprouts all together. There also appears to be small amounts of mold growing on the dirt.

All our plants have grown taller
Our Elodea is much longer than it was last week and the webbing towards the top of the Elodea is much more extensive than it was last week. The water clarity is the same as it was last week. One of our snails seems to be very active while the other has stayed in a similar spot for the past couple of weeks, but it has moved away from the spot we marked before. Our water level has stayed pretty constant. It is about the same level that it was last week.

Seeing new growth popping up, especially after this much time, is exciting! I'm glad we get to have another observation next week so that we can see how much else will change in the upcoming week.
