- There is a lot of moisture circulating through the top portion as seen in the condensation forming on the top. 
- No plant growth to date. 

Aquatic portion: 
- A lot of condensation forming. 
- The elodea continues to grow.
​- Snails are alive and well

  • Is it because the seeds we planted?
  • Is it the amount of water that we put into the top part? Too little?
  • If we were to open up the top part and entered more water, would our flowers grow?
-Aquatic portion is experiencing change.
  • The elodea has grown and is wrapping around the bottom bottle. 
  • The water level has decreased some since Week 1. We marked a line (black marker) and today we marked a line where the water is now (purple marker).  
  • The string that is coming down to the aquatic portion from the terrestrial portion has dropped and it is now mostly in the aquatic portion of the terrarium.The string that is coming down to the aquatic portion from the terrestrial portion has dropped and it is now mostly in the aquatic portion of the terrarium. The string looks dirty and like it is filled with algae. 

We believe that the daphnia died because we cannot find them at all, even after looking through a magnifying glass. We entered three daphnia into our terrarium.

We noticed a small speck on the side of aquatic bottle, we believe that it is a baby snail. That means that the snails are reproducing.

<![CDATA[Week 4 October 20,2015]]>Tue, 27 Oct 2015 14:56:02 GMThttp://science5678.weebly.com/blog/week-4-october-272015We still do NOT have any plant growth. One group member believes because we do not have enough water in our terrarium. Another one believes because we cut too much of our bottle so our terrarium is too low. Our plant on the lower part has definitely grew. I wonder if it grew because of the spring water.

Top Level
-soil looks dry 
-there is a lot of condensation forming at the top 
-no plant growth has occurred

Bottom Level
-condensation has formed around the
-plant is still green but starting to turn brown in places
-water is getting dirtier 
-algae is forming on the string 

The plants on the bottom level are growing out of the water. The plant has actually began to grow. I think it is pretty cool that it has grown without soil. We planted 5 flower seeds and none of them has sprouted. I believe that either the soil is TOO dry or there is not enough water in the bottom level.
  • If we could add water to the top level, would the plants be able to grow?

There is still no plant growth in the terrestrial part of the terrarium and the soil looks dried out. In the aquatic part of the terrarium the water is murky, the snails look dead, and there is something brown growing on the string coming down from the terrestrial part. 

We Wonder:
- Is the water level dependent on the growth?
- Will are flowers sprout next week?

- Mild condensation on the top, only formed on one side 
- Condensation around the rim of the bottom 
- No plant growth, yet 
- Water on the bottom looks a little murky, algae floating around 
- Water level is the same height ( 11.8 cm)
- Daphnea are not visible

We made our terrarium and it was very fun! 
Our materials include:
  • organic soil
  • summer sunshine mix seeds
  • daphnia
  • spring water
  • elodea
  • 1 two liter bottle
  • 1 three liter bottle
  • clear packing tape
  • gravel
  • cotton strings
  • snails

We wonder.....
How will the ecosystem work?
How will the organisms survive?

So far, the snails are stationary and we do not have any plant growth (elodea looks healthy).
We put three daphnia into our terrarium and they are very small. We also planted five flower seeds and we hope they start to grow soon!
