Week 6: 11/6/15

This week we observed our terrarium  and we are continuing to have good growth throughout both ecosystems.  We have a new sprout that is starting to come out of the soil. the other plants are continuing to grow.  There are beans starting to grow off of the stems.  We can see there are lots of roots growing within the soil. There is a lot of condensation on the top half of the terrarium and also on the top half of water ecosystem portion.  The elodea is still pretty clean with the same part still sticking out of the water.   There is mold on the top of the soil by where the string is, which is sticking up above the soil. The string appears to be very dirty. We are unsure if that part of the string was sticking out before. The part of the string that is in the water is very dirty.  The water level may have gone down some.  It is pretty clear with only a few particles floating around. Overall, we are continuing to have good growth.

We predict our 2-tier terrarium will continue to do well.

Questions for thought:

How do you think the mold got inside our terrarium?

Here you can tell that most of the elodea is pretty green with most of it remaining submerged under water.  

Our plants are growing well and you can see how green the sprouts are.  

The string is very dirty.

The roots are continuing to grow throughout the soil, the top tier portion of our terrarium.
