Week 5 (Oct 12, a little bit behind the curve.)

Week five comes in late at week 6, (apologies to all for the timeline anomaly!)
The columns are definitely growing...stuff (ewww....too cool!) It appears that the control is in the lead for stratification, but then I'm a geologist in the making, what would I know about stratifying layers of microbial growth? To restate that, it appears that the control column has the greatest growth of green micro organisms. The layers may be obscured by the prolific growth. A better visual of the layering or stratification can be seen in the 4% saline column; much less growth of the brightly colored, happy looking bacteria though.  As stated, this post is behind the times so may be redundant with another post, (apologies again.)

The columns (10/12/15)

Control, window side

4% saline, window side

8% saline, window side (sensing a pattern here?)

12% saline, again from the window side.

Top view of our protein shakes...ewww, just kidding.

Salinity	Stratification	Height
Control	water	4.2cm
	Sediment	12.2cm
4%	water	3.8cm
	Sediment	10.3cm
8%	water	3.8cm
	Sediment	10.8cm
12%	water	3.4cm
	Sediment	11.6cm

Streaky streak streak

No not the sort of streaking that first comes to a college student's mind. But this red streak thing in our dark mix control column... It's becoming larger. Whatever that means, we're not really sure yet but we are stoked to see it continue to streak. No, still no cool nematode things in our column sadly 😒 However, our covered mix column is still safely wrapped because as we said last time we're just trying to give it some space, you know? It's like a teenager, very fragile, doesn't like sunlight, hides in the basement--aka we imagine whatever is in there does not like UV light so we're just trying to baby it, don't judge.

Enjoy our streaking.
