Our Biosphere
Day 1
We are following along with The Magnifying Glass on their Make-along project: microbe biosphere. Our biosphere is starting to get very colorful. The dirt where we live is reddish orange, and ours is starting to show some black spots all around. Though it’s hard to tell from my photo, there is a layer of clear water on top of the mud, and a fine layer of sediment on top of the water. A darker layer has also formed around the top edge of the mud layer.
Day 18
Day 27
When we compare our biosphere at Day 27 to how it looked on Day 18, we noticed that it has many more black spots in it. There is a layer of dark gray fuzz on top of the mud layer. The water is still clear, but there is a layer of gray powdery-looking stuff on top of the water.
Day 34
Our Microbe Biosphere is still showing some changes. The dirt is looking far less red and has taken on a more brownish/grayish color. There are more black spots all around, and the layer on top of the water looks slightly thicker. The water is still clear, and the layer on top of the mud and under the water is blacker in color and thicker–you can see the line against the glass on top of the mud layer. The main difference between the way the Biosphere looks now and the way it looked on Day 27 is the color of the dirt.

Wow!! Yours is really coming along.
As long as you leave it alone (don’t move it / shake it) you will see even more changes in the coming weeks. This is just the beginning!
